    Are web-based questionnaires accepted in patients attending rehabilitation?2016Ingår i: Disability and Rehabilitation, ISSN 0963-8288, E-ISSN 1464-5165, Vol. 38, nr 24-26, s. 2406-2412Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose: The aim of the present paper was to study preferences for web based self-administered questionnaires (web SAQs) vs. paper-based self-administered questionnaires (paper SAQs) and to evaluate the feasibility of using web SAQs in patients referred to cardiac, lung, occupational and cancer rehabilitation programs. Methods: The patients were approached by mail and given the choice to answer the compulsory SAQs either on paper or on a web-based platform. Results: Hundred and twenty seven out of 183 eligible patients (69.3%) were willing to participate and 126 completed the study. Web SAQs were preferred by 77.7%, and these patients were significantly younger, more often cohabiting and tended to have higher level of education than paper SAQ users. Mean number of data missing per patient was less among the web SAQ users than the paper SAQ users (0.55 vs. 2.15, p <0.001). Costs related to human resources were estimated to be 60% lower with web SAQs compared to paper SAQs. Conclusions: Web SAQs were well accepted among the patients scheduled for rehabilitation, led to less missing data and considerable cost savings related to human resources. Patients referred to rehabilitation should be offered the choice to complete self-administered questionnaires on internet platforms when internet access is common and available.

    The effect of climbing mount everest on spleen contraction and increase in hemoglobin concentration during breath holding and exercise2014Ingår i: High Altitude Medicine & Biology, ISSN 1527-0297, E-ISSN 1557-8682, Vol. 15, nr 1, s. 52-57Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Release of stored red blood cells resulting from spleen contraction improves human performance in various hypoxic situations. This study determined spleen volume resulting from two contraction-evoking stimuli: breath holding and exercise before and after altitude acclimatization during a Mount Everest ascent (8848m). Eight climbers performed the following protocol before and after the climb: 5min ambient air respiration at 1370m during rest, 20min oxygen respiration, 20min ambient air respiration at 1370m, three maximal-effort breath holds spaced by 2min, 10min ambient air respiration, 5min of cycling at 100 W, and finally 10min ambient air respiration. We measured spleen volume by ultrasound and capillary hemoglobin (HB) concentration after each exposure, and heart rate (HR) and arterial oxygen saturation (Sao2) continuously. Mean (SD) baseline spleen volume was unchanged at 213 (101) mL before and 206 (52) mL after the climb. Before the climb, spleen volume was reduced to 184 (83) mL after three breath holds, and after the climb three breath holds resulted in a spleen volume of 132 (26) mL (p=0.032). After exercise, the preclimb spleen volume was 186 (89) mL vs. 112 (389) mL) after the climb (p=0.003). Breath hold duration and cardiovascular responses were unchanged after the climb. We concluded that spleen contraction may be enhanced by altitude acclimatization, probably reflecting both the acclimatization to chronic hypoxic exposure and acute hypoxia during physical work. © Copyright 2014, Mary Ann Liebert, Inc. 2014.

    Is There Evidence that Runners can Benefit from Wearing Compression Clothing?2016Ingår i: Sports Medicine, ISSN 0112-1642, E-ISSN 1179-2035, Vol. 46, nr 12, s. 1939-1952Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Runners at various levels of performance and specializing in different events (from 800 m to marathons) wear compression socks, sleeves, shorts, and/or tights in attempt to improve their performance and facilitate recovery. Recently, a number of publications reporting contradictory results with regard to the influence of compression garments in this context have appeared. Objectives: To assess original research on the effects of compression clothing (socks, calf sleeves, shorts, and tights) on running performance and recovery. Method: A computerized research of the electronic databases PubMed, MEDLINE, SPORTDiscus, and Web of Science was performed in September of 2015, and the relevant articles published in peer-reviewed journals were thus identified rated using the Physiotherapy Evidence Database (PEDro) Scale. Studies examining effects on physiological, psychological, and/or biomechanical parameters during or after running were included, and means and measures of variability for the outcome employed to calculate Hedges’g effect size and associated 95 % confidence intervals for comparison of experimental (compression) and control (non-compression) trials. Results: Compression garments exerted no statistically significant mean effects on running performance (times for a (half) marathon, 15-km trail running, 5- and 10-km runs, and 400-m sprint), maximal and submaximal oxygen uptake, blood lactate concentrations, blood gas kinetics, cardiac parameters (including heart rate, cardiac output, cardiac index, and stroke volume), body and perceived temperature, or the performance of strength-related tasks after running. Small positive effect sizes were calculated for the time to exhaustion (in incremental or step tests), running economy (including biomechanical variables), clearance of blood lactate, perceived exertion, maximal voluntary isometric contraction and peak leg muscle power immediately after running, and markers of muscle damage and inflammation. The body core temperature was moderately affected by compression, while the effect size values for post-exercise leg soreness and the delay in onset of muscle fatigue indicated large positive effects. Conclusion: Our present findings suggest that by wearing compression clothing, runners may improve variables related to endurance performance (i.e., time to exhaustion) slightly, due to improvements in running economy, biomechanical variables, perception, and muscle temperature. They should also benefit from reduced muscle pain, damage, and inflammation.

    The kinetics of blood lactate in boys during and following a single and repeated all-out sprints of cycling are different than in men2015Ingår i: Applied Physiology, Nutrition and Metabolism, ISSN 1715-5312, E-ISSN 1715-5320, Vol. 40, nr 6, s. 623-631Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This study characterized the impact of high-intensity interval training on the kinetics of blood lactate and performance in trained boys and men. Twenty-one boys (11.4 +/- 0.8 years) and 19 men (29.4 +/- 5.0 years) performed a set of four 30-s sprints with 2-min of rest and a single 30-s sprint on 2 separate occasions (randomized order) with assessment of performance. Blood lactate was assayed after each sprint and during 30 min of recovery from both tests. The individual time-curves of blood lactate concentration were fitted to the biexponential function as follows: [LA](t) = [LA](0) + A(1) (1 - e(-gamma 1t)) +A(2) (1 - e (-gamma 2t)), where the velocity parameters gamma(1) and gamma(2) reflect the capacity to release lactate from the previously active muscle into the blood and to subsequently eliminate lactate from the organism, respectively. In both tests, peak blood lactate concentration was significantly lower in the boys (four 30-s sprints: 12.2 +/- 3.6 mmol.L-1; single 30-s sprint: 8.7 +/- 1.8 mmol.L-1) than men (four 30-s sprints: 16.1 +/- 3.3 mmol.L-1; single 30-s sprint: 11.5 +/- 2.1; p < 0.001). The boys exhibited faster gamma(1) (1.4531 +/- 0.65 min; p < 0.001) and gamma(2) (0.059 +/- 0.023 min; p = 0.01) in the single 30-s sprint and faster gamma(2) (0.049 +/- 0.016 min; p = 0.01) in the four 30-s sprints. The worsening of performance from the first to the last of the four 30-s sprints was less pronounced in boys (9.2% +/- 13.9%) than men (19.2% +/- 11.5%; p = 0.01). In the present study boys, when compared with men, exhibited lower Peak blood lactate concentration; less pronounced decline in performance during the sprints concomitantly with more rapid release and elimination during the single 30-s sprint; and faster elimination of lactate following the four 30-s sprints.

    Obalans mellan arbetet och privatlivet bland offentliganställda: betydelsen av kontroll och socialt stöd på arbetsplatsen2017Ingår i: Socialmedicinsk Tidskrift, ISSN 0037-833X, Vol. 94, nr 5, s. 610-622Artikel i tidskrift (Refereegranskat)
    Abstract [sv]

    Obalans mellan arbetet och privatlivet kan leda till ohälsa och sjukfrånvaro. Det finns visst stöd i forskning för att kontroll och socialt stöd i arbetet var för sig relaterar till individers upplevelse av balans. I denna studie undersöks relationen mellan socialt stöd, kontroll och  obalans mellan arbete och privatliv. Vidare studeras additiva och multiplikativa effekter.

    Data är hämtad från en undersökning som gjorts inom offentlig sektor (vård, omsorg och skola) i mellersta Sverige. Enkäten skickades ut till 743 anställda och svarsfrekvensen var 51 procent. En linjär regression genomfördes med obalans som utfall.

    Resultatet visar att kontroll och socialt stöd i arbetet är skyddande faktorer mot obalans. Det finns en additiv effekt, och kontroll och socialt stöd har tillsammans en högre förklaringsgrad än var för sig.

    Test-retest reliability of repeated knee laxity measurements in the acute phase following a knee trauma using a Rolimeter2017Ingår i: Journal of Exercise Rehabilitation, ISSN 2288-176X, Vol. 13, nr 5, s. 550-558Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The purpose was to examine the test-retest reliability of the Rolimeter measurement procedure in the acute time phase, following a substantial knee trauma. In total, 15 participants with acute knee trauma were examined by one single observer at three different time-points with the Rolimeter using a maximum force. The selected time-points were: baseline (0–7 days after the trauma), midpoint (3–4 weeks after the trauma), and endpoint (3–4 weeks after the trauma). The anterior-posterior displacement was recorded where the endpoint evaluation was used as the reference value. The mean anterior laxity scores remained constant over the measurement time-points for both knees, with an anterior laxity that was 2.7 mm higher (on average) in the injured than the noninjured knee (9.5 mm vs. 6.8 mm). The mean difference (i.e., bias) between laxity scores, for the injured knee, measured at endpoint versus baseline was 0.2±1.0 mm and −0.2±1.1 mm when measured at endpoint versus midpoint, with average typical errors of 0.7 and 0.8 mm and intra-class correlations that were very strong (both r=~0.93). For the same comparisons on the noninjured knee, systematic bias was close to zero (0.1±0.3 and −0.1±0.3 mm, respectively), and both the intra-class correlations were almost perfect (r=~0.99). The current study implicates that repeated Rolimeter measurements are relatively reliable for quantifying anterior knee laxity during the acute time-phases following knee trauma. Hence, the Rolimeter, in combination with manual tests, seems to be a valuable tool for identifying anterior cruciate ligament injuries.

    A numerical model for fatigue effects in whole-body human exercise2016Ingår i: Mathematical and Computer Modelling of Dynamical Systems, ISSN 1387-3954, E-ISSN 1744-5051, Vol. 22, nr 1, s. 21-38Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    A physiology-based fatigue model was developed and tested, with the long-term objective to study optimal pacing strategies in cross-country skiing. The model considers both aerobic and anaerobic power contributions, with different demands for carbohydrate fuel. The fatigue model accumulates traces from anaerobic efforts, and dissipates fatigue exponentially. The current fatigue value affects the effective work rate output. A limited reservoir of fuel is considered. This paper discusses the numerical formulations. Examples show the relevance of the model for basic regimes of power output, and give qualitatively relevant results, but demonstrate the need for individual physiological parameters. Further examples study the model's predictions with respect to interval training strategies, with conclusions on work rates and interval lengths.

    Fysisk aktivitet efter skoltid: En studie på Östersunds kommuns 7:e och 9:e klassare2013Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Att fysisk aktivitet har en mängd positiva effekter på människors hälsa och välmående är väl känt i dagens samhälle. För barns utvecklingsprocess, både motoriskt, socialt och personligt är det viktigt att vara fysiskt aktiv. Syftet med studien var att dokumentera fysiska aktivitetsvanor efter skoltid hos Östersunds kommuns 7:e och 9:e  klassare. Studien utfördes via enkäter där 382st elever medverkade under lektionstid under vårterminen 2013. Majoriteten av eleverna ansåg att det var viktigt att vara fysiskt aktiv efter skoltid. Flickor var något mer fysiskt aktiva gällande antal dagar och timmar än pojkar. Samma tendens sågs gällande årskurs 9 jämfört med årskurs 7. De två främsta orsakerna till att ej vara mer fysiskt aktiv var brist på tid och bristande intresse. För pojkar var den vanligaste formen av fysisk aktivitet fotboll och för flickor promenader. Majoriteten av eleverna ansåg sig ha stöd från sina föräldrar och vänner till att vara fysiskt aktiv. Sammanfattningsvis, vetskapen om att fysisk aktivitet efter skoltid är viktig är väl känt för de allra flesta elever men de svenska rekommendationerna (60min måttligt/intensiv aktivitet per dag) levs ej upp till i praktiken. Positivt att se var att en klar majoritet av eleverna ansåg sig ha stöd av föräldrar och vänner till att vara fysiskt aktiv.

    Abstract [en]

    Background and objectives: Stress-related illness is a growing public health problem in Sweden and it is the most common reason for sick leave today. Stress-related illness causes suffering on a number of levels and affects the patient’s health and life in the long term. The stress-related ill health also leads to consequences for society, causing high costs for sick leave and health care as well as lost workforce since people partially or entirely lose their capacity to work. Research on stress-related ill health and rehabilitation often underline work-related conditions as crucial in dealing with the problem. There is also research that points out psychosocial factors in understanding stress-related ill health. What we know little about is the existential perspective of clinical burn-out. Therefore, it is of importance to investigate people’s existential experiences of clinical burn-out and the significance of an existential perspective in rehabilitation.

    Aim: The overall aim of this thesis is to gain insight into the existential experience of clinical burn-out as well as to highlight the significance of an existential perspective in rehabilitation. In addition, the thesis aims to reach a deeper understanding of clinical burn-out from an existential point of view and contribute to the field with knowledge of the existential dimension of health.

    Methods: The study, conducted in 2011, is based on qualitative interviews made with an inductive hermeneutic approach. Five patients and seven care givers were interviewed, focusing their existential experiences of clinical burn-out as well as their experiences of rehabilitation with an existential approach. A strategic selection was made of informants in the context of a rehabilitation program with an existential approach for people diagnosed with clinical burn-out. The data was analysed in two steps. In the first step the data was interpreted with an inductive hermeneutic approach. In step two of the analysis, the data was interpreted with a deductive hermeneutic approach, using Karl Jasper’s concept of limit situation as a way of interpreting the existential experience. Aaron Antonovsky’s concept sense of coherence was used as a tool for understanding components that can contribute to restoring health.

    Results: In this study, the patients describe clinical burn-out as a comprehensive existential experience that can be perceived as being in between life and death, in a shadow world, trapped in a dead end. It’s a situation characterized by being powerless. It creates a need to comprehend one’s situation in order to be able to regain control and manage it. It’s a struggle to make sense of the life situation. When not being met with understanding, the patients lose hope. Existential issues in terms of meaning, existence and life choices become urgent. Working with the existential perspective requires trust, openness from both caregiver and patient, distinctness, a way to communicate it and courage to take on the challenge of dealing with existential issues. The perspective also requires that the existential suffering can be contained. Dealing with existential questions leads to self-knowledge and insights that enables a possibility to make different choices and leave negative behavioural patterns. Also, it can lead to a discovery of spirituality and religion as a resource in life. Besides their personal struggle for meaning, the patients see an existential void in society, leaving people without tools to handle existential needs. This is understood as something that affects people’s ability to handle stressful times in life.

    The care providers understand burn-out as a manifestation of a way of living that is not sustainable. It is an existential experience embodied in body and mind that can be experienced as being drained of life. It’s an existential challenge, causing grief when realizing one’s limitations as a human being. Also, loss of meaning and sense of existential vulnerability due to an experience of being annihilated is crucial for understanding the deep existential crisis that clinical burn-out can induce. This situation makes the patient ask existential questions about identity, meaning, values and direction. In the burnout-process the patients have distanced themselves from their own self and therefore need to reconnect with themselves. This makes the existential questions central in the rehabilitation as a way to reconnect to inner strength and resources, which are prerequisites for starting a health promoting, sustainable process which is empowering, making it possible to see oneself as a human being who experience meaning, not only as a patient with a diagnosis. Instead of finding meaning in the diagnosis, the patient’s existential questions and the existential experience is a key to moving forward, out of the situation. Meaning-making is therefore important in the rehabilitation.

    A holistic-existential approach and view of man makes it possible to work with the complexity of the situation. The holistic-existential approach creates synergies and offers an extra tool both for the caregiver and the patient. Focusing on the patient’s resources and competence makes it possible to see the crisis as a way to learn from it.

    The existential perspective in health care and rehabilitation is enabled by competence, openness, reliance, empathy and respect when meeting the patient. It also requires courage to take on the challenge of dealing with existential issues. It can be hard for both the patient and the care giver to confront existential suffering. It is the responsibility of the care giver to enable the existential perspective by acknowledging and making the existential perspective possible to communicate and work it through.

    The care providers understands values in modern society as contributing to people’s experience of feeling alone with existential needs, which intensifies their existential aloneness.

    The care providers’ experience is that the biomedical paradigm aggravates an existential perspective. The perspective is not associated with the care situation. There is a lack of knowledge about and understanding of the value of the existential perspective, all the way from the decision-making level to the clinical meeting with the patient. In addition, the paradigm affects how the patients express their illness. Also, the perspective requires time. Existential perspectives, therefore, tend to be concealed in the health care context.

    Applying Karl Jasper’s concept of limit situation, clinical burn-out can be interpreted as a defining existential experience. It can be understood as a limit situation when humans realize their limitations and at the same time get insights that are crucial for their lives. It’s an experience they wish they had not gone through, but on the other hand, it has led to insights they do not want to be without. The meaning-making process is health promoting by recreating meaning, the fundamental part of sense of coherence, which is crucial for a salutogenic direction.

    Conclusion: The existential state that the clinical burnout patients go through can, using Karl Jasper’s concept, be understood as a limit situation. According to Jasper’s reasoning, the limit situation can be perceived as facing an abyss, making it clear one has limitations as a human being. At the same time, the experience can be perceived as reaching a limit where humans can get insights about human life that can enhance life. Clinical burn-out, using Aaron Antonovsky’s concept, can be understood as a loss of the components that create sense of coherence. Loss of meaning is particularly central for understanding burn-out.

    Consequently, it is crucial to acknowledge the existential challenge that the patient is facing, as well as the importance of the meaning-making process for facilitating a movement in a health promoting manner. It gives a deeper understanding of the challenges and needs of patients suffering from clinical burn-out.

    The existential dimension of health has been highlighted in health promotion, but gets little attention in practice. This is especially significant in the health care context. This points out the need for a discussion about how the existential health dimension can be used as a resource in health care and rehabilitation and how this resource for health can be applied in a better way in health promotion and public health.

    Symptoms of moderate exercise in subzero temperatures - An experimental exposure study2018Ingår i: European Respiratory Journal, ISSN 0903-1936, E-ISSN 1399-3003, Vol. 52Artikel i tidskrift (Övrigt vetenskapligt)
    Abstract [en]

    Humans react to cold with various symptoms. Previous studies enquiring about symptoms during cold exposure have for the most part been population based studies using questionnaries and have focused on a narrow spectrum of symptoms. The purpose of this study was to study the effect of cold air and physical exercise on a wide range of symptoms in healthy individuals.

    A total of 31 healthy subjects were experimentally exposed to +10 °C and -10 °C in an environmental chamber for one hour, on two separate occasions. During each exposure, subjects performed an intermittent moderate-intensity running protocol between 62-78% of maximal oxygen consumption (VO2 max). At five timepoints, before, during and after the exposures, subjects were asked about 18 symptoms and their intensity. The Borg CR10 scale was used to rate the intensity from 0 to 11, where 0 meant "none" and 11 meant "maximal". The sum of all five Borg CR10-scores were added together to form a single score for each exposure. Paired Wilcoxon signed-rank test was used for analysis. Data are presented as medians.

    Symptoms of cough, eye irritation, physical discomfort, and cold extremities were present only at -10 °C. Compared to exercise in +10 °C, exercise in -10 °C induced significantly higher summed symptom scores for eye irritation 2.0 vs 0.5 (p=0.011), rhinitis 12.0 vs 8.0 (p=0.000), nasal irritation 3.5 vs 0.5 (p=0.001), cold face 7.0 vs 1.0 (p=0.000), physical discomfort 6.5 vs 0.0 (p=0.000), and cold extremities 10.0 vs 0.5 (p=0.000).

    In healthy subjects, moderate-intensity exercise in -10 °C can induce and enhance the intensity of a wide range of symptoms. Symptoms of the lower airways were infrequent and mild.

    Symptom av måttlig träning i minusgrader: En experimentell exponeringsstudie2018Konferensbidrag (Övrigt vetenskapligt)
    Abstract [sv]

    Bakgrund: Exponering för kyla leder till ökad sjuklighet och dödlighet i befolkningen. Tidigare studier av symptom i samband med köldexponering har mestadels varit befolkningsbaserade enkätstudier fokuserade på ett smalt symptomspektrum. Syftet meddenna studie var att undersöka effekten av kyla och fysisk aktivitet på ett brett spektrumav symptom hos friska individer.Material och metod: Trettioen friska försökspersoner exponerades i en köldkammare för +10 °C och -10 °C under en timme, vid två separata tillfällen. Under varje exponeringsprang försökspersonerna intermittent på 62-78% av maximal syreupptagningsförmåga. Vid fem tillfällen, före, under och efter exponeringarna, frågades försökspersonerna om 18 symptom och dessas intensitet. Borgs CR10 skala användes för att skatta intensitetenfrån 0 till 11, där 0 betydde ”inget alls” och 11 betydde ”maximalt”. Maximalt Borg-värdeför varje symptom under exponeringarna jämfördes med värdena innan exponeringarna. Summan av alla fem Borg CR10-värdena jämfördes mellan de två exponeringarna. PairedWilcoxon signed-rank test användes för analyser. Data presenteras som medianvärden.Resultat: En signifikant stegring av symptomen hosta, ögonirritation, fysiskt obehag ochkalla extremiteter förekom endast vid -10 °C. I jämförelse med fysisk aktivitet i +10 °C, gav fysisk aktivitet i -10 °C upphov till signifikant högre summerade värden för ögonirritation 2,0 jfr 0,5 (p=0,011), rinit 12,0 jfr 8,0 (p=0,000), irritation i näsan 3,5 jfr 0,5 (p=0,001), kyla i ansiktet 7,0 jfr 1,0 (p=0,000), fysiskt obehag 6,5 jfr 0,0 (p=0,000), och kalla extremiteter 10,0 jfr 0,5 (p=0,000).Slutsats: Hos friska individer kan fysisk aktivitet på måttlig intensitet i -10 °C ge upphovtill och öka intensiteten av ett brett spektrum av symptom. Symptom från de nedre luftvägarna var milda och inte frekventa vid de aktuella exponeringarna.

    Fysiologisk jämförelse av sprintintervallträning och högintensiv intervallträning2013Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Sprintintervallträning (SIT) och högintensiv intervallträning (HIIT) är relativt nya träningsmetoder som används av både idrottsaktiva och motionärer för att öka både prestationsförmåga och hälsofrämjande fysiologiska effekter. Syftet av denna studie var därmed att undersöka de fysiologiska förändringar som uppkom efter två veckors SIT och HIIT hos tio unga, friska motionärer. Försökspersonerna delades in i två homogena grupper, en SIT-grupp (n = 5) och en HIIT-grupp (n = 5). De båda grupperna utförde fyra förtester för att fastställa kroppssammansättning, anaerob effekt, benstyrka och maximal syreupptagningsförmåga innan en två veckors träningsintervention startade. Under det första intervallpasset mättes de akuta effekterna av träningen och efter avslutad träningsperiod upprepades förtesterna för att påvisa eventuella fysiologiska förändringar. Det fanns en förändring hos SIT-gruppen i average power (SIT: före = 6,7 ± 1,6 watt/kg, efter = 7,5 ± 1,1 watt/kg, HIIT: före = 7,3 ± 1,0 watt/kg, efter = 7,3 ± 1,0 watt/kg) samt en förändring i laktatnivå på 75 watt under maxtestet för de båda grupperna (SIT: före = 2,0 ± 0,7 mmol, efter = 2,4 ± 0,8 mmol, HIIT: före = 2,2 ± 0,4 mmol, efter = 1,9 ± 0,8 mmol) (P<0,05). Två veckors SIT samt HIIT gav ingen signifikant förändring i syreupptag, muskelstyrka, tid till utmattning eller kroppssammansättning. Sammanfattningsvis krävs det vidare forskning med fler försökspersoner samt längre träningsintervention för att kunna fastställa möjliga fysiologiska skillnaders mellan SIT och HIIT.

    Correlates of posttraumatic stress disorder in adultswith congenital heart disease2017Ingår i: Congenital Heart Disease, ISSN 1747-079X, E-ISSN 1747-0803, Vol. 12, nr 3, s. 357-363Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: The aims of this study were to compare the level of posttraumatic stress disorder between adults with and without congenital heart disease, and to examine the correlates of posttraumatic stress disorder (e.g., sociodemographics).

    Design: Cross-sectional.

    Setting: Two university-affiliated heart hospitals in Tehran, Iran.

    Patients: A sample of 347 adults with congenital heart disease aged 18–64 years (52% women), and 353 adults without congenital heart disease matched by sex and age (±2 years) was recruited.

    Outcome Measures: The PTSD Scale: Self-report version was used to assess the diagnosis and severity of posttraumatic stress disorder. Hierarchical multivariate logistic regression analyses were performed to explore correlates of likely posttraumatic stress disorder diagnosis among each group of participants.

    Results: The posttraumatic stress disorder in the patients was comparable to those of the control group, except for increased arousal (P = .027) which was scored higher among the patients. Over 52% of adults with congenital heart disease met the criteria for a likely posttraumatic stress disorder diagnosis compared with 48% of adults without congenital heart disease. The regression analyses among patients revealed that elevated depressive symptoms (OR = 1.27) and a positive history of cardiac surgery (OR = 2.02) were significantly associated with posttraumatic stress disorder. The model could explain 29% of the variance in posttraumatic stress disorder.

    Conclusions: The high and comparable prevalence of posttraumatic stress disorder among patients and nonpatients highlight the significance of the context in which adults with congenital heart disease may face other/additional stressors than disease-related ones, an issue that clinicians need also take into account. Furthermore, the association of posttraumatic stress disorder with elevated depressive symptoms warrant a comprehensive psychological assessment and management of adults with congenital heart disease, in particular among those with a history of invasive procedures.

    The Psychosocial Situation of Adults with Congenital Heart Disease in Iran2013Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Background and objectives:Adults with congenital heart disease (CHD) are a new group of patients with a prevalence of 4 per 1000. They have evolved as a result of significant improvements in medical management during the past decades. However, adults with CHD experience various medical and social challenges that may influence their psychosocial functioning. Providing appropriate medical, rehabilitation and social care for adults with CHD, and indeed improving their well-being require the evaluation of their current psychosocial situation. This thesis aims to increase the understanding of the mental health, somatic symptoms, social support, style of coping, quality of life and life satisfaction of adults with CHD and to examine the possible contributing factors in the context of a developing country; issues not addressed in the current literature.Methods:This thesis is based on four studies. Study I recruited 347 consecutive CHD patients (18-64 years) from two heart hospitals in Tehran, Iran. The study iscross-sectional and focused on sex differences in socio-economic status, lifestyle and medical characteristics of adults with CHD. Studies II, III and IV havea cross-sectional case-control design comparing the aforementioned CHD patients with 353 non-CHD participants, matched by sex and age. Outcome variables were anxiety, depressive and somatic symptoms (Study II), styles of coping (Study III), and life satisfaction/quality of life (Study IV). The data were analysed with bivariate and multivariate methods. Multivariate linear regression analyses were performed to scrutinize the association of demographic/socio-economic variables, social support, mental health, and medical variables with the aforementioned outcome variables among adults with CHD (Studies II, III, IV). Results:Study I showed that women with CHD were more often married and had children and were less often employed, but had healthier behaviour compared to men. Even though most of the patients received regular medical viiicare from different typesof medical professionals, half of them had no knowledge about the type of their cardiac defect. Study II showed that CHD patients experienced more anxiety and somatic symptoms than the healthy controls, whereas there were no differences in depressive symptoms. Perceived financial strain, lower social support and low annual income were positively associated with worse outcome in mental health and somatic symptoms. None of the medical variables were related to anxiety, depressive and somatic symptoms. Study III showed that the styles of coping of the CHD patients were comparable to those of the control group and CHD per se was not associated with a certain style of coping, except for palliative reaction pattern. Problem-focused styles of coping were associated with being never married, parenthood, higher level of anxiety and somatic symptoms, lower level of depressive symptoms and higher social support. Emotion-focused styles of coping were associated with annual income and higher level of anxiety. None of theadopted coping strategies were related to the heart disease variables. Study IV showed that adults with CHD had poorer quality of life and lower life satisfaction than the control group. However, CHD was associated only with decreased overall quality of life and its physical health domain, and life and health satisfaction. Among CHD patients, higher quality of life was associated with female sex, younger age, employment status, having less emotional distress and higher social support, while life satisfaction was associated with female sex, being employed, less emotional distress and higher social support. Conclusions:The results support the notion that psychosocial factors contribute to the well-being of adults with CHD.Socio-economic factors, emotional health and social support are significant determinants in nearly all outcomes of interest which need to be considered by health care providers and policy makers in their efforts to improve the health ofadults with CHD. However, longitudinal studies are warranted to establish causal linksand qualitative studies are recommended to deepen the understanding of coping and quality of life.

    Lifetime abuse and perceived social support among the elderly: a study from seven European countries2017Ingår i: European Journal of Public Health, ISSN 1101-1262, E-ISSN 1464-360X, Vol. 27, nr 4, s. 686-692Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Being a victim of abuse during one's life course may affect social relations in later life. The aims of this study were to: (i) examine the association between lifetime abuse and perceived social support and (ii) identify correlates of perceived social support among older persons living in seven European countries. Methods: A sample of 4467 women and men aged 60-84 years living in Germany, Greece, Italy, Lithuania, Portugal, Spain and Sweden was collected through a cross-sectional population-based study. Abuse (psychological, physical, sexual, financial and injury) was assessed through interviews or interviews/self-response questionnaire based on the Conflict Tactics Scale-2 and the UK study on elder abuse. Perceived social support was assessed by the Multidimensional Scale of Perceived Social Support. Results: Victims of lifetime abuse perceived poorer social support in later life. Multivariate analyses showed that high levels of perceived social support were associated with being from Greece and Lithuania (compared to Germany), being female, not living alone, consuming alcohol and physical activity. Poorer perceived social support was associated with being from Portugal, being old, having social benefits as the main source of income, experiencing financial strain and being exposed to lifetime psychological abuse and injuries. Conclusions: Our findings showed that exposure to psychological abuse and injuries across the lifespan were associated with low levels of perceived social support, emphasizing the importance of detection and appropriate treatment of victims of abuse during their life course. Future research should focus on coping strategies buffering the negative effects of abuse on social relationships.

    Hopelessness among adults with congenital heart disease: Cause for despair or hope?2017Ingår i: International Journal of Cardiology, ISSN 0167-5273, E-ISSN 1874-1754, Vol. 230, nr March 2017, s. 64-69Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background

    Adults with congenital heart disease (CHD) face unique life courses and challenges that may negatively influence their psychological functioning. The aims of this study were to (1) examine the level of hopelessness among adults with CHD in comparison with non-CHD participants and (2) identify correlates of elevated hopelessness among adults with CHD.

    Methods

    We enrolled 347 patients with CHD (18–64 years, 52.2% female) and 353 matched (by sex/age) non-CHD persons in this cross-sectional study. Hopelessness was assessed by Beck Hopelessness Scale. Hierarchical multiple logistic regression analyses were performed to explore correlates of elevated hopelessness.

    Results

    The mean total hopelessness score did not significantly differ between the CHD and non-CHD groups. Twenty-eight percent of CHD patients had elevated hopelessness scores. Within the CHD patient sample, regression analyses revealed that being male (odds ratio = 2.62), not having children (odds ratio = 3.57), being unemployed (odds ratio = 2.27), and elevated depressive symptoms (odds ratio = 1.21) were significantly associated with hopelessness. Regular physical activity (odds ratio = 0.36) emerged as a protective factor and all CHD disease parameters were unrelated to hopelessness. The final model explained 43% of the variance in hopelessness.

    Conclusions

    Adult CHD teams are encouraged to continue to explore strategies to support patients to live as rich and full as lives as possible by pursuing relationships, employment and physical activity, as well as managing depression and hopelessness.

    Life-time abuse and mental health among older persons: a European study2017Ingår i: Journal of Aggression, Maltreatment & Trauma, ISSN 1092-6771, E-ISSN 1545-083X, Vol. 26, nr 6, s. 590-607Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This study aimed to investigate the association of lifetime abuse and mental health among older persons, considering associated factors (e.g., demographics) through a cross-sectional design. We recruited 4,467 women and men ages 60–84 years from 7 European cities. Mental health was measured with the Hospital Anxiety and Depression Scale, and abuse (psychological, physical, sexual, financial, and physical injuries) based on the Revised Conflict Tactics Scale and the UK survey of abuse/neglect of older people. Multiple logistic regression analyses showed that country of residence, low educational level, and experienced financial strain increased the odds of probable cases of anxiety and depression. Female sex, white-collar profession, and financial support by social/other benefits/or partner income were associated with higher odds of anxiety, while older age and experience of lifetime injury were associated with increased odds of depressive symptoms. The findings of this study indicate that socioeconomic factors, as well as experienced lifetime severe physical abuse leading to injuries, are significant in perceived mental health of adults in later life.

    Quality of life and life satisfaction among adults with and without congenital heart disease in a developing country2015Ingår i: European Journal of Preventive Cardiology, ISSN 2047-4873, E-ISSN 2047-4881, Vol. 22, nr 2, s. 169-179Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background Life-expectancy of adults with congenital heart disease (CHD) has improved world-wide, but there are limited data on these patients' experiences of quality of life (QoL), life satisfaction (LS), and their determinants (e.g. social support), particularly among patients from developing countries.

    Design Cross-sectional case-control.

    Methods A total of 347 CHD patients (18-64 years, 52.2% women) and 353 non-CHD participants, matched by sex/age, were recruited from two heart hospitals in Tehran, Iran. LS and QoL served as dependent variables, and demographic/socioeconomic status, mental-somatic symptoms, social support, and clinical factors (e.g. defect category) served as independent variables in multiple regression analyses once among all participants, and once only among CHD patients.

    Results The CHD patients had significantly lower scores in LS and all domains of QoL than the control group. However, having CHD was independently negatively associated only with overall QoL, physical health, and life and health satisfaction. Additionally, multivariate analyses among the CHD patients revealed that female sex, younger age, being employed, less emotional distress, and higher social support were significantly associated with higher perceived QoL in most domains, while LS was associated with female sex, being employed, less emotional distress, and better social support. Neither QoL nor LS was associated with cardiac defect severity.

    Conclusions The adults with CHD had poorer QoL and LS than their non-CHD peers in our developing country. Socio-demographics, emotional health, and social support were important 'determinants' of QoL and LS among the CHD patients. Longitudinal studies are warranted to establish causal links.

    Style of Coping and its Determinants in Adults with Congenital Heart Disease in a Developing Country2014Ingår i: Congenital Heart Disease, ISSN 1747-079X, E-ISSN 1747-0803, Vol. 9, nr 4, s. 349-360Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective The objective of this study is to compare coping strategies between adults with and without congenital heart disease and to scrutinize the associations between different available resources (e.g., social support) and adoption of certain coping strategies.

    DesignThe study has a cross-sectional case-control design.

    SettingThe study was conducted in two university-affilliated heart hospitals in Tehran, Iran.

    Patients The participants comprised 347 persons (18–64 years) with and 353 individuals without congenital heart disease, matched by gender and age.

    Outcome Measures Coping strategies, assessed with the Utrecht Coping List-short form, were compared between both groups. Block-wise multiple regression analyses were conducted to scrutinize the associations between different independent variables (e.g., demographic/socioeconomic statuses) and adoption of certain styles of coping (dependent variables) among all participants and separately for each group.

    Results The styles of coping in the patients were comparable with those of the control group. Multivariate analyses revealed that congenital heart disease per se was not associated with style of coping except for palliative reaction pattern. The active problem-solving coping style was associated with never married marital status, parenthood, unemployment, higher level of anxiety/somatic symptoms, lower level of depressive symptoms, and better social support. The avoidance behavior style was associated with having a low income, whereas the expression of emotion style was associated with higher anxiety symptoms, experience of financial strain, and income. None of the adopted coping strategies was related to the heart disease variables.

    Conclusions The adults with congenital heart disease coped as well as adults without congenital heart disease. Marital status, parenthood, annual income, financial strain, psychological adjustment, and perceived social support were important explanatory factors in adopting a certain style of coping among adults with congenital heart disease. However, longitudinal studies with repeated measures are warranted.

    Gender differences in health conditions and socio-economic status of adults with congenital heart disease in a developing country2013Ingår i: Cardiology in the Young, ISSN 1047-9511, E-ISSN 1467-1107, Vol. 23, nr 02, s. 209-218Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background Providing appropriate care for adults with congenital heart disease requires the evaluation of their current situation. There is limited research in Iran about these patients, particularly in relation to gender differences in the demographic/socio-economic and lifestyle factors, as well as disease parameters.

    Materials and methods The sample consisted of 347 congenital heart disease patients in the age group of 18–64 years, including 181 women, assessed by an analytical cross-sectional study. The patients were recruited from the two major heart hospitals in Tehran. Data were collected using questionnaires.

    Results The mean age of the patients was 33.24 years. Women were more often married and more often had offspring than men (p < 0.001). Educational level and annual income were similar between women and men. Unemployment was higher among women (p < 0.001), but financial strain was higher among men (p < 0.001). Smoking, alcohol, and water-pipe use was higher among men than among women (p < 0.001). Cardiac factors, for example number of cardiac defects, were similar among women and men, except that there were more hospitalisations owing to cardiac problems, for example arrhythmia, among men. Disease was diagnosed mostly at the hospital (57.4%). Most medical care was provided by cardiologists (65.1%). Only 50.1% of patients had knowledge about their type of cardiac defect.

    Conclusion Gender differences exist in the socio-economic and lifestyle characteristics of adults with congenital heart disease, in some cases related to the disease severity. Our findings also point to the need for interventions to increase patients’ knowledge about, and use of, healthier lifestyle behaviours, irrespective of gender. Furthermore, providing appropriate jobs, vocational training, and career counselling may help patients to be more productive.

    Anxiety, depressive and somatic symptoms in adults with congenital heart disease2013Ingår i: Journal of Psychosomatic Research, ISSN 0022-3999, E-ISSN 1879-1360, Vol. 74, nr 1, s. 49-56Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective

    Despite the improvement in life-expectancy of adults with congenital heart disease, they may experience unique medical and social challenges that could impact on their psychological functioning. The aims of this study were to address the experience of anxiety, depressive and somatic symptoms among adults with congenital heart disease in comparison with that of non-heart diseased persons considering the role of various factors (e.g. socio-economic).

    Methods

    In cross-sectional case–control study, the participants consisted of 347 patients with congenital heart disease (18–64 years, 52.2% female) and 353 matched (by sex/age) non-heart diseased persons. The participants completed a questionnaire. The data were analyzed with bivariate and multivariate methods.

    Results

    In bivariate analyses, scores in anxiety and somatic symptoms were higher among patients than the healthy controls (both at p ≤ 0.001), whereas the groups did not differ in depressive symptoms. Following multiple-linear-regression-analyses, only the association between congenital heart disease and somatic symptoms was confirmed. Among the patients, perceived financial strain was significantly related to anxiety, depressive and somatic symptoms; lower perceived social support to anxiety and depression; and low annual income to somatic symptoms. Additionally, somatic symptoms were associated with anxiety and depressive symptoms, and vice versa. And no medical variables were related to anxiety, depressive and somatic symptoms.

    Conclusions

    Congenital heart disease was only independently associated with somatic symptoms. Financial strain, social support and co-existence of emotional distress with somatic symptoms should be considered in developing appropriate interventions to improve the well-being of patients with congenital heart disease. However, longitudinal research is warranted to clarify causality.

    The prevalence of lifetime abuse among older adults in seven European countries2016Ingår i: International Journal of Public Health, ISSN 1661-8556, E-ISSN 1661-8564, Vol. 61, nr 8, s. 891-901Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives To investigate the lifetime prevalence rate of abuse among older persons and to scrutinize the associated factors (e.g. demographics).

    Methods This cross-sectional population-based study had 4467 participants, aged 60–84, from seven European cities. Abuse (psychological, physical, sexual, financial and injuries) was measured based on The Revised Conflict Tactics Scale, and the UK survey of abuse/neglect of older people.

    Results Over 34 % of participants reported experiencing lifetime psychological, 11.5 % physical, 18.5 % financial and 5 % sexual abuse and 4.3 % reported injuries. Lifetime psychological abuse was associated with country, younger age, education and alcohol consumption; physical abuse with country, age, not living in partnership; injuries with country, female sex, age, education, not living in partnership; financial abuse with country, age, not living in partnership, education, benefiting social/partner income, drinking alcohol; and sexual abuse with country, female sex and financial strain.

    Conclusions High lifetime prevalence rates confirm that elder abuse is a considerable public health problem warranting further longitudinal studies. Country of residence is an independent factor associated with all types of elder abuse which highlights the importance of national interventions alongside international collaborations.

    Validity and reliability properties of canine short-term heart rate variability measures-a pilot study2015Ingår i: Journal of Veterinary Behavior: Clinical Applications and Research, ISSN 1558-7878, E-ISSN 1878-7517, Vol. 10, nr 5, s. 384-390Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The objective of the pilot study was to compare validity and reliability properties of Polar RS800CX (Polar Electro Oy, Kempele, Finland) against simultaneously recorded electrocardiogram (ECG) measuring time- and frequency-based short-term heart rate variability (HRV) parameters, in dogs during stationary standing position. Five-minute recordings with less than 5% error rates from inter-beat interval (IBI) series obtained by Polar RS800CX and ECG, in 8 adult dogs, were used for HRV analysis. Polar data were statistically compared to the ECG data to assess for systematic differences in time- and frequency-based HRV parameters. Relative and absolute reliabilities were estimated by intraclass correlation coefficient, Spearman ρ, Bland and Altman analysis, standard error of measurement, and standard error of measurements in percentage. Paired t test was used to determine the statistical significance of differences between the measurement methods. Results: There were high correlation coefficients between HRV parameters obtained from Polar RS800CX and ECG. Intraclass correlation coefficients were 0.98-1.00, and Spearman ρ was 0.93-0.98. There were differences between the methods in 2 HRV parameters, the standard deviation of normal-to-normal IBIs (SDNN) (P = 0.035) and the square root of the mean squared differences of successive normal-to normal IBIs (RMSSD) (P = 0.034). Standard error of measurements was between 2.8-11.6% in ECG and between 2.6-11.8% in Polar, indicating rather high measurement error in 3 of the HRV parameters in both measurement methods. Close agreements and high correlation estimates in this pilot study indicated acceptable relative reliability in Polar RS800CX measuring time- and frequency-based HRV parameters in the group of dogs studied. However, the present pilot study revealed differences between Polar RS800CX and ECG in time-based standard deviation of normal-to-normal and square root of the mean squared differences of successive normal-to normal parameters, and that small amounts of erroneous IBI segments from Polar negatively impact on the validity and reliability properties of Polar RS800CX. © 2015 Elsevier Inc.

    Comparison of Polar® RS800CX heart rate monitor and electrocardiogram for measuring inter-beat intervals in healthy dogs2015Ingår i: Physiology and Behavior, ISSN 0031-9384, E-ISSN 1873-507X, Vol. 138, nr January, s. 247-253Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The aim of the present study was to assess the criterion validity, relative reliability and level of agreement ofPolar® RS800CX heart rate monitor measuring inter-beat intervals (IBIs), compared to simultaneously recordedelectrocardiogram (ECG) in dogs.Methods: Five continuous minutes of simultaneously recorded IBIs from Polar® RS800CX and Cardiostore ECG in11 adult healthy dogs maintaining standing position were analyzed. Polar® data was statistically compared toECG data to assess for systematic differences between the methods. Three different methods for handling missingIBI data were used. Criterion validities were calculated by intraclass correlation coefficients (ICCs) and corresponding95% confidence intervals (CIs). Relative reliabilities and levels of agreement were calculated by ICCsand the Bland and Altman analysis for repeated measurements per subject.Results: Correlation coefficients between IBI data from ECG and Polar® RS800CX varied between 0.73 and 0.84depending on how missing values were handled. Polar® was over- and underestimating IBI data compared toECG. The mean difference in log transformed (base10) IBI data was 0.8%, and 93.2% of the values were withinthe limits of agreement. Internally excluding three subjects presenting IBI series containing more than 5% erroneousIBIs resulted in ICCs between 0.97 and 0.99. Bland and Altman analysis (n = 8) showed mean differencewas 1.8 ms, and 98.5% of the IBI values were plotted inside limits of agreement.Conclusion: This study showed that Polar® systematically biased recorded IBI series and that it was fundamentalto detect measurement errors. For Polar® RS800CX heart rate monitor to be used interchangeably to ECG, byshowing excellent criterion validity and reliable IBI measures in group and individual samples, only less than5% of artifacts could be accepted.

    Validity and reliability of Polar® RS800CX heart rate monitor, measuring heart rate in dogs during standing position and at trot on a treadmil2013Ingår i: Physiology and Behavior, ISSN 0031-9384, E-ISSN 1873-507X, Vol. 114-115, s. 1-5Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Abstract

    The aim of the present study was to assess criterion validity, and relative and absolute reliability of Polar® RS800CX heart rate monitor, compared to simultaneously recorded electrocardiogram (ECG) data, in measuring heart rate of dogs during standing position and at trot on a treadmill.

    Methods

    Heart beats from Polar® RS800CX and Cardiostore ECG were recorded simultaneously during seven continuous minutes in standing position and at trot, in 10 adult healthy dogs. Polar® data was statistically compared to ECG data for a variety of mean beats per minute (BPM), standard deviation and confidence interval. Criterion validity was calculated by Pearson product moment correlation method and intraclass correlation coefficient (ICC2.1). Relative and absolute reliability were calculated by ICC2.1, the Bland and Altman analysis and standard error of measurement (SEM and SEM%).

    Results

    The correlation, criterion validity, between Polar® and ECG data in standing position was r = 0.99 (p < 0.0005) and at trot r = 0.97 (p < 0.0005). Polar® data was not significantly different from ECG data. Mean difference between ECG and uncorrected Polar® data was − 0.6 BPM in standing position and − 0.6 BPM at trot. Polar® was over- and underestimating ECG data. SEM and SEM% in standing were ± 2.6 BPM and 3.0%, at trot ± 3.8 BPM and 3.1%, indicating that measurement errors were low.

    Conclusion

    This study showed that the criterion validity and the instrument reliability were excellent in Polar® RS800CX heart rate measuring system. The equipment seemed to be valid and reliable in measuring BPM in the dogs studied during submaximal cardiovascular conditions such as in standing position and at trot on a treadmill.

    A novel approach for lactate threshold assessment based on rating of perceived exertion2013Ingår i: International Journal of Sports Physiology and Performance, ISSN 1555-0265, E-ISSN 1555-0273, ISSN ISSN 1555-0265, Vol. 8, nr 3, s. 263-270Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This study tested the hypothesis that the DMAX (for maximal distance) method could be applied to ratings of perceived exertion (RPE), to propose a novel method for individual detection of the lactate threshold (LT) using RPE alone during an incremental test to exhaustion. Twenty-one participants performed an incremental test on a cycle ergometer. At the end of each stage, lactate concentration was measured and the participants estimated RPE using the Borg CR100 scale. The intensity corresponding to the fixed lactate values of 2 or 4 mmol • L-1 (2mM and 4mM), the ventilatory threshold (VT), the respiratory-compensation point (RCP), and the instant of equality of pulmonary gas exchange (RER=1.00) were determined. Lactate (DMAX La) and RPE (DMAX RPE) thresholds were determined using the DMAX method. Oxygen uptake (VO2), heart rate, and power output measured at DMAX RPE and at D MAX La were not statistically different. Bland-Altman plots showed small bias and good agreements when DMAX RPE was compared with the DMAX La and RER=1.00 methods (bias = -0.05% and -2% of VO2max, respectively). Conversely, VO2 from the D MAX RPE method was lower than VO2 at 4 mM and at RCP and was higher than VO2 at 2 mM and at VT. VO2 at D MAX RPE was strongly correlated with VO2 at D MAX La (r = .97), at RER=1.00 (r = .97), at 2 mM (r = .85), at 4 mM (r = .93), at VT (r = .95), and at RCP (r = .95). The combination of the DMAX method with the RPE responses permitted precise and individualized estimates of LT using the DMAX method.

    Alterations in aerobic energy expenditure and neuromuscular function during a simulated cross-country skiathlon with the skating technique2015Ingår i: Human Movement Science, ISSN 0167-9457, E-ISSN 1872-7646, Vol. 40, s. 326-340Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Here, we tested the hypothesis that aerobic energy expenditure (AEE) is higher during a simulated 6-km (2 loops of 3-km each) "skiathlon" than during skating only on a treadmill and attempted to link any such increase to biomechanical and neuromuscular responses. Six elite male cross-country skiers performed two pretesting time-trials (TT) to determine their best performances and to choose an appropriate submaximal speed for collection of physiological, biomechanical and neuromuscular data during two experimental sessions ((exp)). Each skier used, in randomized order, either the classical (CL) or skating technique (SK) for the first 3-km loop, followed by transition to the skating technique for the second 3-km loop. Respiratory parameters were recorded continuously. The EMG activity of the triceps brachii (TBr and vastus lateralis (VLa) muscles during isometric contractions performed when the skiers were stationary (i.e., just before the first loop, during the transition, and after the second loop); their corresponding activity during dynamic contractions; and pole and plantar forces during the second loop were recorded. During the second 3-km of the 'IT, skating speed was significantly higher for the SK-SK than CL-SK. During this second loop, AEE was also higher (+1.5%) for CL-SKexp than SK-SKexp, in association with higher VLa EMG activity during both isometric and dynamic contractions, despite no differences in plantar or pole forces, poling times or cycle rates. Although the underlying mechanism remains unclear, during a skiathlon, the transition between the sections of classical skiing and skating alters skating performance (i.e., skiing speed), AEE and neuromuscular function.
