    Bringing light into the dark: effects of compression clothing on performance and recovery2013Ingår i: International Journal of Sports Physiology and Performance, ISSN 1555-0265, E-ISSN 1555-0273, Vol. 8, nr 1, s. 4-18Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    To assess original research addressing the effect of the application of compression clothing on sport performance and recovery after exercise, a computer-based literature research was performed in July 2011 using the electronic databases PubMed, MEDLINE, SPORTDiscus, and Web of Science. Studies examining the effect of compression clothing on endurance, strength and power, motor control, and physiological, psychological, and biomechanical parameters during or after exercise were included, and means and measures of variability of the outcome measures were recorded to estimate the effect size (Hedges g) and associated 95% confidence intervals for comparisons of experimental (compression) and control trials (noncompression). The characteristics of the compression clothing, participants, and study design were also extracted. The original research from peer-reviewed journals was examined using the Physiotherapy Evidence Database (PEDro) Scale. Results indicated small effect sizes for the application of compression clothing during exercise for shortduration sprints (10-60 m), vertical-jump height, extending time to exhaustion (such as running at VO2maxor during incremental tests), and time-trial performance (3-60 min). When compression clothing was applied for recovery purposes after exercise, small to moderate effect sizes were observed in recovery of maximal strength and power, especially vertical-jump exercise; reductions in muscle swelling and perceived muscle pain; blood lactate removal; and increases in body temperature. These results suggest that the application of compression clothing may assist athletic performance and recovery in given situations with consideration of the effects magnitude and practical relevance.

    Near-Infrared Spectroscopy: More Accurate Than Heart Rate for Monitoring Intensity in Running in Hilly Terrain2017Ingår i: International Journal of Sports Physiology and Performance, ISSN 1555-0265, E-ISSN 1555-0273, Vol. 12, nr 4, s. 440-447Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose:

    To 1) investigate the cardiorespiratory and metabolic response of trail running and 2) evaluate whether heart rate (HR) adequately reflects the exercise intensity or whether the tissue saturation index (TSI) could provide a more accurate measure when running in hilly terrain.

    Methods:

    Seventeen competitive runners (female: n=4, V’O2max: 55±6 mL·kg−1·min−1; male: n=13, V’O2max: 68±6 mL·kg−1·min−1) performed a time trial on an off-road trail course. The course was made up of two laps covering a total distance of 7 km and included six steep up- and downhill sections with an elevation gain of 486 m. All runners were equipped with a portable breath-by-breath gas analyzer, HR belt, global positioning system receiver and near-infrared spectroscopy (NIRS) device to measure the TSI.

    Results:

    During the trail run, the exercise intensity within the uphill and downhill sections was 94±2% and 91±3% of HRmax, 84±8% and 68±7% of V’O2max, respectively. The oxygen uptake (V’O2) increased within the uphill and decreased within the downhill sections (P< .01). While HR was unaffected by the altering slope conditions, the TSI was inversely correlated to the changes in V’O2 (r = - .70, P< .05).

    Conclusions:

    The HR was unaffected by the continuously changing exercise intensity, however, the TSI reflected the alternations in V’O2. Recently used exclusively for scientific purpose, this NIRS based variable may offer a more accurate alternative to HR to monitor running intensity in the future, especially for training and competition in hilly terrain.

    Muscle oxygenation asymmetry in ice speed skaters is not compensated by compression2014Ingår i: International Journal of Sports Physiology and Performance, ISSN 1555-0265, E-ISSN 1555-0273, Vol. 9, nr 1, s. 58-67Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    PURPOSE:

    The present investigation assessed tissue oxygenation and local blood volume in both vastus lateralis muscles during 3000 m race simulations in elite speed skaters on ice and the effects of leg compression on physiological, perceptual and performance measures.

    METHODS:

    Ten (6 female) elite ice speed skaters completed two on-ice trials with and without leg compression. Tissue oxygenation and local blood volume in both vastus lateralis muscles was assessed by applying near-infrared spectroscopy (NIRS). Continuous measures of oxygen uptake, ventilation, heart rate and velocity were conducted throughout the race simulations as well as blood lactate concentration and ratings of perceived exertion before and after the trials. In addition, lap times were assessed.

    RESULTS:

    The investigation of tissue oxygenation in both vastus lateralis muscles revealed an asymmetry (P<0.00; effect size=1.81) throughout the 3000 m race simulation. The application of leg compression did not affect oxygenation asymmetry (smallest P=0.99; largest effect size=0.31) or local blood volume (P=0.33; 0.95). Lap times (P=0.88; 0.43), velocity (P=0.24; 0.84), oxygen uptake (P=0.79; 0.10), ventilation (P=0.11; 0.59), heart rate (P=0.21; 0.89), blood lactate concentration (P=0.82; 0.59) and ratings of perceived exertion (P=0.19; 1.01) were also unaffected by the different types of clothing.

    CONCLUSION:

    Elite ice speed skaters show an asymmetry in tissue oxygenation of both vastus lateralis muscles during 3000 m events remaining during the long gliding phases along the straight sections of the track. Based on our data, we conclude no performance enhancing benefits from wearing leg compression under a normal racing suit.

    A novel compression garment with adhesive silicone stripes improves repeated sprint performance: a multi-experimental approach on the underlying mechanisms.2014Ingår i: BMC Sports Science, Medicine and Rehabilitation, ISSN 2052-1847, Vol. 6, nr 21Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND:

    Repeated sprint performance is determined by explosive production of power, as well as rapid recovery between successive sprints, and there is evidence that compression garments and sports taping can improve both of these factors.

    METHODS:

    In each of two sub-studies, female athletes performed two sets of 30 30-m sprints (one sprint per minute), one set wearing compression garment with adhesive silicone stripes (CGSS) intended to mimic taping and the other with normal clothing, in randomized order. Sub-study 1 (n = 12) focused on cardio-respiratory, metabolic, hemodynamic and perceptual responses, while neuronal and biomechanical parameters were examined in sub-study 2 (n = 12).

    RESULTS:

    In both sub-studies the CGSS improved repeated sprint performance during the final 10 sprints (best P < 0.01, d = 0.61). None of the cardio-respiratory or metabolic variables monitored were altered by wearing this garment (best P = 0.06, d = 0.71). Also during the final 10 sprints, rating of perceived exertion by the upper leg muscles was reduced (P = 0.01, d = 1.1), step length increased (P = 0.01, d = 0.91) and activation of the m. rectus femoris elevated (P = 0.01, d = 1.24), while the hip flexion angle was lowered throughout the protocol (best P < 0.01, d = 2.28) and step frequency (best P = 0.34, d = 0.2) remained unaltered.

    CONCLUSION:

    Although the physiological parameters monitored were unchanged, the CGSS appears to improve performance during 30 30-m repeated sprints by reducing perceived exertion and altering running technique.

    Learning style differences between nursing and teaching students i Sweden: A comparative study2013Ingår i: International Journal of Higher Education, ISSN 1927-6044, Vol. 2, nr 1, s. 22-34Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The teaching profession has been continually challenged to provide evidence of the effectiveness of teaching and learning methods. Teacher education, as well as nursing education, is currently undergoing reforms in Sweden. At the university where the research was conducted, teaching and nursing programs are two priority educational programs and maybe knowledge of learning styles can improve the quality of these programs. The purpose of this research was to examine the learning style preferences for two student groups, teachers and nurses, to analyze their differences in light of international research on learning styles. The study involved 78 teaching students and 78 nursing students. Twenty subscales of the Productivity Environmental Preference Survey (PEPS) (Dunn, Dunn, & Price, 1984; 1991;2000) were used to identify the participants’ learning style preferences. The results showed statistically significant differences between the two student groups. In comparison to teaching students, more nursing students were highly motivated, kinesthetic, and preferred authorities. More teaching students were highly persistent. The findings suggest the need for widely diverse teaching approaches and conscious didactic action skills in higher education, as well as implementation of learning strategies for students.

    Lived biographies of changing integration regimes: Migrant narratives ofinstitutional support and labor market in/exclusion in Sweden2016Konferensbidrag (Refereegranskat)
    Abstract [en]

    The aim of this study is to explore the interconnection between lived biographies and changing integration policies through migrant narratives on institutional support and labor market experiences. The approach applied in this study allows us to pay particular attention to the dynamic character of integration and to make links between personal, organizational and policy domains, analyzing the shifted integration regimes from the standpoint of migrants. The Swedish politics of integration has during the last year’s undergone vast changes and in 2010, the largest change in the Swedish history of integration policies was performed (etableringsreformen) which meant an increasingly emphasized focus on employment and workfare before welfare and the responsibility for new migrants was transferred from the municipalities to the employment service. As a consequence the rhetoric of integration in Sweden also changed, from what was in municipalities talked about as introduction, to what is now talked about as reception and establishment. By combining immigrants’ subjective views and evaluations with the trajectories of their work biographies, we will discuss changing integration regimes as ‘lived experiences’ of individuals who are subjected to and employed in different occupations that the different integration regimes produces.

    Lived Experiences of Changing Integration Policies:: Immigrant Narratives of Institutional Support and Labour Market Inclusion/Exclusion in Sweden2018Ingår i: Nordic Journal of Migration Research, ISSN 1799-649X, E-ISSN 1799-649X, Vol. 8, nr 1, s. 25-34Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This study aims to map, locate and make visible the everyday experiences of newly arrived immigrants in government-sponsored integration activities and to trace how these experiences are linked to changes in policy. The study pays particular attention to the dynamic nature of integration and draws links between personal, organisational and policy domains while analysing shifting integration policies from the standpoint of immigrants. Swedish integration policy has undergone vast changes during recent years as the government implements one of the largest changes in Swedish history, beginning in 2010. With this came an emphasis on employment and workfare over welfare. Consequently, the rhetoric of integration in Sweden also changed from what in municipalities was called an introduction to a sense of establishment. By examining the subjective views of immigrants, we discuss the lived experiences of individuals who are subjected to and employed in different occupations due to various integration regimes.

    Downhill turn techniques and associated physical characteristics in cross-country skiers2014Ingår i: Scandinavian Journal of Medicine and Science in Sports, ISSN 0905-7188, E-ISSN 1600-0838, Vol. 24, nr 4, s. 708-716Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Three dominant techniques are used for downhill turning in cross-country skiing. In this study, kinematic, kinetic, and temporal characteristics of these techniques are described and related to skier strength and power. Twelve elite female cross-country skiers performed six consecutive turns of standardized geometry while being monitored by a Global Navigation Satellite System. Overall time was used as an indicator of performance. Skiing and turning parameters were determined from skier trajectories; the proportional use of each technique was determined from video analysis. Leg strength and power were determined by isometric squats and countermovement jumps on a force plate. Snow plowing, parallel skidding, and step turning were utilized for all turns. Faster skiers employed less snow plowing and more step turning, more rapid deceleration and earlier initiation of step turning at higher speed (r = 0.80–0.93; all P < 0.01). Better performance was significantly correlated to higher mean speed and shorter trajectory (r

    = 0.99/0.65; both P < 0.05) and to countermovement jump characteristics of peak force, time to peak force, and rate of force development (r  = -0.71/0.78/-0.83; all P < 0.05). In conclusion, faster skiers used step turning to a greater extent and exhibited higher maximal leg power, which enabled them to combine high speeds with shorter trajectories during turns.

    A time-efficient reduction of fat mass in 4 days with exercise and caloric restriction2015Ingår i: Scandinavian Journal of Medicine and Science in Sports, ISSN 0905-7188, E-ISSN 1600-0838, Vol. 25, nr 2, s. 223-233Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    To determine whether a fast reduction in fat mass can be achieved in 4 days by combining caloric restriction (CR: 3.2kcal/kg body weight per day) with exercise (8-h walking+45-min arm cranking per day) to induce an energy deficit of approximate to 5000kcal/day, 15 overweight men underwent five experimental phases: pretest, exercise+CR for 4 days (WCR), control diet+reduced exercise for 3 days (DIET), and follow-up 4 weeks (POST1) and 1 year later (POST2). During WCR, the diet consisted solely of whey protein (n=8) or sucrose (n=7) (0.8g/kg body weight per day). After WCR, DIET, POST1, and POST2, fat mass was reduced by a mean of 2.1, 2.8, 3.8, and 1.9kg (P<0.05), with two thirds of this loss from the trunk; and lean mass by 2.8, 1.0, 0.5, and 0.4kg, respectively. After WCR, serum glucose, insulin, homeostatic model assessment, total and low-density lipoprotein cholesterol and triglycerides were reduced, and free fatty acid and cortisol increased. Serum leptin was reduced by 64%, 50%, and 33% following WCR, DIET, and POST1, respectively (P<0.05). The effects were similar in both groups. In conclusion, a clinically relevant reduction in fat mass can be achieved in overweight men in just 4 days by combining prolonged exercise with CR.

    Exercise Preserves Lean Mass and Performance during Severe Energy Deficit: The Role of Exercise Volume and Dietary Protein Content2017Ingår i: Frontiers in Physiology, ISSN 1664-042X, E-ISSN 1664-042X, Vol. 8, artikel-id 483Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The loss of fat-free mass (FFM) caused by very-low-calorie diets (VLCD) can be attenuated by exercise. The aim of this study was to determine the role played by exercise and dietary protein content in preserving the lean mass and performance of exercised and non-exercised muscles, during a short period of extreme energy deficit (similar to 23 MJ deficit/day). Fifteen overweight men underwent three consecutive experimental phases: baseline assessment (PRE), followed by 4 days of caloric restriction and exercise (CRE) and then 3 days on a control diet combined with reduced exercise (CD). During CRE, the participants ingested a VLCD and performed 45 min of one-arm cranking followed by 8 h walking each day. The VLCD consisted of 0.8 g/kg body weight/day of either whey protein (PRO, n = 8) or sucrose (SU, n = 7). FFM was reduced after CRE (P < 0.001), with the legs and the exercised arm losing proportionally less FFM than the control arm [57% (P < 0.05) and 29% (P = 0.05), respectively]. Performance during leg pedaling, as reflected by the peak oxygen uptake and power output (Wpeak), was reduced after CRE by 15 and 12%, respectively (P < 0.05), and recovered only partially after CD. The deterioration of cycling performance was more pronounced in the whey protein than sucrose group (P < 0.05). Wpeak during arm cranking was unchanged in the control arm, but improved in the contralateral arm by arm cranking. There was a linear relationship between the reduction in whole-body FFM between PRE and CRE and the changes in the cortisol/free testosterone ratio (C/FT), serum isoleucine, leucine, tryptophan, valine, BCAA, and EAA (r = -0.54 to -0.71, respectively, P < 0.05). C/FT tended to be higher in the PRO than the SU group following CRE (P = 0.06). In conclusion, concomitant low-intensity exercise such as walking or arm cranking even during an extreme energy deficit results in remarkable preservation of lean mass. The intake of proteins alone may be associated with greater cortisol/free testosterone ratio and is not better than the ingestion of only carbohydrates for preserving FFM and muscle performance in interventions of short duration.

    Superior Intrinsic Mitochondria Respiration in Women Than in Men2018Ingår i: Frontiers in Physiology, ISSN 1664-042X, E-ISSN 1664-042X, Vol. 9, nr AUG, artikel-id 1133Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Sexual dimorphism is apparent in humans, however, to date no studies have investigated mitochondria! function focusing on intrinsic mitochondrial respiration (i.e., mitochondrial respiration for a given amount of mitochondrial protein) and mitochondrial oxygen affinity (p50(mito)) in relation to biological sex in human. A skeletal muscle biopsy was donated by nine active women, and ten men matched for maximal oxygen consumption (VO2max) and by nine endurance trained men. Intrinsic mitochondrial respiration, assessed in isolated mitochondria, was higher in women compared to men when activating complex I (Cl-p) and complex I+II(Cl+IIp) (p < 0.05), and was similar to trained men (Cl-p, p = 0.053; Cl+IIp, p = 0.066). Proton leak and p50(mito) to were higher in women compared to men independent of VO2max. In conclusion, significant novel differences in mitochondrial oxidative function, intrinsic mitochondrial respiration and p50(mito) to exist between women and men. These findings may represent an adaptation in the oxygen cascade in women to optimize muscle oxygen uptake to compensate for a lower oxygen delivery during exercise.

    Officials Reflections about Health Promoting Factors among Newly Arrivals: An Introductory Analysis2017Ingår i: International Journal of Community & Family Medicine, ISSN 2456-3498, Vol. 2, nr 1, artikel-id IJCFM-124Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Resulting from conflicts, millions of peoples have been forced to leave their countries of origin. In Sweden, the Employment Agency is responsible for making decisions of immigrants’ residence in municipalities and in co-operation with these allow the immigrants’ establishment in the society. Preventive interventions among migrants and refugees, and health interventions in heterogeneous populations show that increased participation in society has positive imprints on health development. A new country includes getting acquaintance with non-familiar cultures. For example, other expectations on rules of gender, sickness, and illness. Recent years the low density populated areas in northern Sweden have received a high number of refugees in comparison with their population size. The purpose of this study was to explore how officials the Employment Agency and a selection of municipalities reflect over and define health promoting factors in their meetings with newly arrived.

    Methods: All officials (N 68) in one of the four northern counties were invited to recording their reflections on health promoting factors close to their meetings with newly arrived. The officials recorded how they defined health promoting factors according to the Audit method. The data collection of experiences of importance considering health promotion and social determinants was collected by five focus group interviews with twenty-three officials.

    Results: This study showed that the officials defined access to the health care, participation in the society, and sufficient collaboration between the authorities for not losing valuable time during the establishment period as imported factors for their clients’ opportunities for health. The officials take power among males for given, while they more often reflected over lack of power among women. However, the Swedish ideal of gender as equal quite often a challenge the newly arrivals.

    How Bullying Involvement is Associated with the Distribution of Parental Background and With Subjective Health Complaints Among Swedish Boys and Girls2013Ingår i: Social Indicators Research, ISSN 0303-8300, E-ISSN 1573-0921, Vol. 111, nr 3, s. 775-783Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This study aimed to analyze how bullying involvement is associated with the distribution of parental background and with subjective health complaints (SHC) among Swedish boys and girls. Data were collected from the World Health Organization, Health Behavior in School-aged Children (WHO/HBSC) survey, measurement years 1997/1998, 2001/2002 and 2005/2006. A total of 11,972 boys (50.6 %) and girls (49.4 %) in grades five, seven and nine participated in the study. The adolescents were categorized in subgroups according to parental background: Swedish (80.1 %), mixed (10.5 %) and foreign(9.7 %). Multivariate logistic regressions were used to estimate remaining risk of SHC in the categories of bullying involvement. The frequencies of bullying involvement once or more were: none involved (74.8 %), victims (10.6 %), bullies (10.3 %) and bully/victims (4.4 %). Six out of ten involved in bullying were boys. Boys of foreign background were more involved as bullies compared to boys of mixed or Swedish background. Girls of foreign background were more involved in all three categories of bullying than girls of mixed or Swedish background. Increased risk of SHC was estimated among all adolescents involved in bullying, with highest OR in the category of bully/victims, OR 3.95 (CI 3.13–4.97) for the boys and OR 4.51 (CI 4.51–6.40) for the girls. The multivariate models were stable even after adjustment for socio-demographics. There are some associations between bullying involvement and parental background. Regardless of parental background, family affluence, family structure and gender, all adolescents involved in bullying are at increased risk of SHC.

    Kroniskt obstruktiv lungsjukdom: Egenvård och coping2013Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Bakgrund: Kroniskt obstruktiv lungsjukdom (KOL) är en sjukdom som ökar i utbredning. Sjukdomen kännetecknas av tilltagande dyspné och funktionsnedsättning hos den drabbade. KOL saknar botemedel och individen tvingas att hantera sin kroniska sjukdom med andra metoder. Syfte: Syftet med litteraturstudien var att belysa hur individer med KOL hanterar sin levnadssituation och vilka egenvårds- och copingstrategier de använder sig av. Metod: Litteraturstudien innefattade granskning, värdering, kvalitetsbedömning, analysering och sammanställning av material från 13 vetenskapliga artiklar. Resultat: Individer med KOL byter ofta till en mindre aktiv livsstil. De planerar och prioriterar dagliga aktiviteter och väger fördelar mot nackdelar vid beslut om egenvårdsaktiviteter. Ett mål i livet beskrevs vara en balans mellan liv och sjukdomshantering. Må bra för stunden jämfördes med att må bra längre fram i livet. Erfarenheter av dyspné och veta vad som fungerar kunde skapa effektiva metoder att hantera andnöden. Diskussion: Genom att hantera sjukdomssymtomen kan många problem motverkas. Ibland kan individen behöva mycket uppmuntran och stöd medan det i andra fall räcker med individens egna ansträngning. Slutsats: Kunskap om hur individen hanterar sin KOL kan leda till bättre insatser av sjukvården och ökad möjlighet för sjuksköterskan att stödja individens motivation till egenvård.

    Risk behaviour in Swedish adolescents: is shared physical custody after divorce a risk or a protective factor?2013Ingår i: European Journal of Public Health, ISSN 1101-1262, E-ISSN 1464-360X, Vol. 23, nr 1, s. 3-8Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: The increase in shared physical custody in Sweden has been dramatic; 20 years ago only a small percentage of adolescents lived in shared physical custody, but currently ∼30% of the adolescents whose parents have separated or divorced divide their residence between parents. We hypothesized that living in shared physical custody or in a single-parent family is associated with a higher prevalence of adolescent risk behaviour than living in a two-parent family. METHODS: Data on 15-year-old adolescents from the 2005/2006 to 2009/2010 Swedish Health Behaviour in School-aged Children (HBSC) survey were analysed using logistic regression. RESULTS: Adolescents living in shared physical custody had slightly higher rates of risk behaviour compared with adolescents from two-parent families, but significantly lower rates than their counterparts from single-parent families. Their odds of being a smoker or having been drunk were 60 and 50% higher, respectively, than those of their counterparts in two-parent families. CONCLUSION: Shared physical custody after marriage break-up seems to constitute a health protective factor for adolescents' health and problem behaviour. In order to deepen our understanding of the positive and negative aspects of shared physical custody, our study should be followed by qualitative analyses and longitudinal studies of adolescents' experiences.

    Shared physical custody after family split-up: implications for health and well-being in Swedish schoolchildren.2013Ingår i: Acta Paediatrica, ISSN 0803-5253, E-ISSN 1651-2227, Vol. 102, nr 3, s. 318-323Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    AIM: In Sweden, shared physical custody following a parental separation has emerged as means for children to keep close relationships with both parents. Previous studies show that children benefit from regular contact with both parents, who share responsibility for their social, emotional, and economic welfare. In this study we investigate any associations between family arrangements, i.e. two parent, single and shared physical custody families and child health outcomes and whether this association was modified by parent-child communication Methods Data on 11-15-year-old children from the 2005/2006 and 2009/2010 Swedish Health Behaviour in School-aged Children survey were analysed using multivariate logistic regression RESULTS: Children in shared physical custody were more likely than children in two-parent families to report multiple health complaints (OR 1.26) and low well-being (OR 1.71). When variables of parent-child communication were entered in the model, the initial differences remained between children living in shared physical custody and those living in two-parent families. Conclusion Children in shared physical custody and single parent families are more at risk of negative outcomes compared to children in two parent families. This association was not modified by parent-child communication in children in shared custody families, indicating that the communication equals that in two-parent family children.

    Nutritional intake in elite cross-country skiers during a simulated sprint race2017Konferensbidrag (Refereegranskat)
    Abstract [en]

    Introduction: Habitual nutritional intakes in cross-country skiers have previously been reported (Fogelholm et al., 1992), however in elite cross-country skiers there is limited knowledge about race-specific nutritional practices, or the prevalence of dehydration and persistent low energy availability (EA). This study aimed to investigate, in the context of a simulated sprint race, energy intake, macronutrient intake, hydration status and the risk of persistent low EA in elite cross-country skiers. Methods: Thirty-two male (n = 18) and female (n = 14) elite Swedish cross-country skiers completed weighed food records the day prior to (day 1) and the day of a simulated sprint race (day 2); the food records were analysed for energy (kcal/kg), macronutrient (g/kg) and fluid intake (L). Urine specific gravity (USG) was also measured on day 1 and day 2. The risk for persistent low EA was assessed in the female skiers using the Low Energy Availability in Females Questionnaire (LEAF-Q; Melin et al., 2014). Results were analysed using a three-way mixed ANOVA. Statistical significance was set to a level of p ≤ 0.05. Results: Males had a higher energy intake (65±9 kcal/kg) on day 1, (pre-race) compared with day 2 (simulated sprint race; 58±9kcal/kg; p = 0.002). Females consumed 57±10 kcal/kg on day 1, which was similar to their day 2 energy intake (54±6 kcal on day 2; p > 0.05). Males consumed less carbohydrate (8.2±2.3g/kg) on day 1 compared with day 2 (8.9±2.3g/kg) (p = 0.026), as did females, consuming 7.0±1.5g/kg on day 1, and 8.4±1.7g/kg on day 2 (p = 0.003). There were similar fluid intakes across the two days for males (p > 0.05) and females (p > 0.05). Nine of the 18 males and 6 of the 14 females were dehydrated (USG > 1.020) on day 1, and 9 males and 5 females were dehydrated on day 2. Five of the 14 females were classified as being at risk of persistent low EA. Discussion: This study provides an initial insight into nutritional competition habits in elite cross-country skiers. The findings indicate that elite skiers’ nutritional intakes are consistent with guidelines, particularly those for endurance athletes’ carbohydrate intake for competitive events (Burke et al., 2001). There was however some evidence of persistent low EA and dehydration, suggesting additional considerations that may be relevant to cross-country skiers’ nutritional intakes for sprint races.

    Bioelectrical impedance vector analysis (BIVA) for measuring the hydration status in young elite synchronized swimmers2017Ingår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 12, nr 6, artikel-id e0178819Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose The assessment of body hydration is a complex process, and no measurement is valid for all situations. Bioelectrical impedance vector analysis (BIVA) has emerged as a relatively novel technique for assessing hydration status in sports. We applied BIVA a) to determine hydration changes evoked by an intense synchronized swimming (SS) training session; b) to characterize the sample of young elite swimmers in relation with a nonathletic reference population; and c) to generate its 50%, 75% and 95% percentiles of the bioelectrical variables. Methods Forty-nine elite SS female swimmers of two age categories, comen (Co: 13.9 ± 0.9 years, n = 34) and junior (Jr: 16.3 ± 0.6 years, n = 15), performed a long, high intensity training session. Body mass (BM) and bioelectrical variables (R, resistance; Xc, reactance; PA, phase angle; and Z, impedance module) were assessed pre-and post-Training. BIVA was used to characterize 1) the distribution pattern of the bioelectrical vector (BIA vector) for both age groups, and 2) pre-To post-Training BIA vector migration. Bioelectrical variables were also correlated with BM change values. Results Most swimmers were mostly located outside the 75% and some beyond the 95% percentile of the bioelectrical tolerance ellipses of the general population. The BIA vector showed statistically significant differences in both Co (T2= 134.7, p = 0.0001) and Jr (T2 = 126.2, p &lt; 0.001). Both groups were also bioelectrically different (T2= 17.6, p &lt; 0.001). After the training session, a decrease in BM (p = 0.0001) and an increase in BIA variables (p = 0.01) was observed. BIVA also showed a significant pre-post vector migration both in Co (T(T2 = 82.1; p &lt; 0.001) and Jr (T2 = 41.8; p &lt; 0.001). No correlations were observed between BM changes and bioelectrical variables. Conclusions BIVA showed specific bioelectrical characteristics in young elite SS athletes. Considering the decrease in BM and the migration of the BIA vector, we conclude that the homeostatic hydration status of these young elite female swimmers was affected by the execution of intense training sessions. From a methodological perspective, BIVA appears to be sensitive enough to detect subtle hydration changes, but further research is needed to ensure its validity and reliability. Moreover, these findings highlight the importance of ensuring adequate fluid intake during training in young SS athletes.

    Heart rate variability to assess ventilatory threshold in ski-mountaineering2015Ingår i: European Journal of Sport Science, ISSN 1746-1391, E-ISSN 1536-7290, Vol. 15, nr 7, s. 615-622Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The capacity to predict the heart rate (HR) and speed at the first (VT1) and second (VT2) ventilatory thresholds was evaluated during an incremental ski-mountaineering test using heart rate variability (HRV). Nine skiers performed a field test to exhaustion on an alpine skiing track. VT1 and VT2 were individually determined by visual analysis from gas exchanges (VT1V and VT2V) and time-varying spectral HRV analysis (VT1fH, VT2fH and VT2H). VT1 could not be determined with the HRV methods used. On the contrary, the VT2 was determined in all skiers. No significant difference between HR and speed at VT2H and VT2V was observed (174.3 +/- 5.6 vs. 174.3 +/- 5.3 bpm, and 6.3 +/- 0.9 and 6.3 +/- 0.9 km h(-1), respectively). Strong correlations were obtained for HR (r = 0.91) and speed (r = 0.92) at VT2H and VT2V with small limits of agreement (+/- 3.6 bpm for HR). Our results indicated that HRV enables determination of HR and speed at VT2 during a specific ski-mountaineering incremental test. These findings provide practical applications for skiers in order to evaluate and control specific training loads, at least when referring to VT2.

    Sexual and physical intimate partner violence among women using prenatal care in Nampula, Mozambique2015Konferensbidrag (Refereegranskat)
    Abstract [en]

    Abstract

    Background: Intimate partner violence (IPV) is a major public health problem worldwide but research on IPV in Africa remains limited. This study aims to estimate the prevalence of sexual and physical intimate partner violence against women and its associated factors, in a sample of women using prenatal care in  Nampula, province-Mozambique.

    Methods: This is a cross-sectional study, carried out in six health units, from February 2013 to January 2014. One in every three pregnant women who visited primary health facilities for the first pre-natal appointment was eligible and invited to participate. After obtaining informed consent 869 pregnant answered the Conflict Tactics Scale 2. Odds ratios (OR) and respective 95% confidence intervals (95%CI) were calculated by using Logistic Regression.

    Results: The prevalence of sexual abuse ever in life was 49% and of physical abuse was 46%. The past year prevalence was 46% and 44% for sexual and physical abuse, respectively. Sexual abuse and physical violence occurred in every age group. Significant associations were found between previous neonatal deaths and being physically abused, during the life-time (OR= 3.00, 95% IC: 1.67 to 5:39), and the past year (OR=3.23, 95% CI: 1.80 - 5.80).

    Conclusion: This study found a high lifetime and past year violence prevalence among women using prenatal care in Mozambique. Prenatal care provides a window of opportunity for identifying women who experience violence.

    Message 1

    The prevalence of intimate partner violence is very high among women in Mozambique and prenatal care can be a sentinel setting

    Message 2

    The implementation of strategies to support women victims of violence in Mozambique is urgently needed

    Sexual and physical intimate partner violence among women using antenatal care in Nampula, Mozambique2018Ingår i: Journal of Public Health in Africa, ISSN 2038-9922, E-ISSN 2038-9930, Vol. 9, nr 1, s. 1-6, artikel-id 744Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The aim was to estimate the prevalence of sexual and physical intimate partner violence (IPV) and its associated factors, in a sample of pregnant women using antenatal care (ANC) in Nampula province - Mozambique. This cross-sectional study was carried out in six health units in Nampula, from February 2013 to January 2014. Overall, 869 participants answered the Conflict Tactics Scale 2. The lifetime and past year prevalence of sexual abuse was 49% and 46%, and of physical abuse was 46% and 44%, respectively. Lifetime and past year sexual abuse was significantly associated with living as a couple, alcohol drinking and having a past diagnosis of gonorrhea. Lifetime and past year physical abuse increased significantly with age and was associated with living as a couple, alcohol drinking and history with syphilis. The prevalence of lifetime and previous year violence among women using ANC was high and similar showing that most women were constantly exposed to IPV. ANC provides a window of opportunity for identifying and acting on violence against women.

    Doublet discharge stimulation increases sarcoplasmic reticulum Ca2+ release and improves performance during fatiguing contractions in mouse muscle fibres2013Ingår i: Journal of Physiology, ISSN 0022-3751, E-ISSN 1469-7793, Vol. 591, nr 15, s. 3739-3748Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Double discharges (doublets) of motor neurones at the onset of contractions increase both force and rate of force development during voluntary submaximal contractions. The purpose of this study was to examine the role of doublet discharges on force and myoplasmic free [Ca2+] ([Ca2+](i)) during repeated fatiguing contractions, using a stimulation protocol mimicking the in vivo activation pattern during running. Individual intact fibres from the flexor digitorum brevis muscle of mice were stimulated at 33 degrees C to undergo 150 constant-frequency (five pulses at 70 Hz) or doublet (an initial, extra pulse at 200 Hz) contractions at 300 ms intervals. In the unfatigued state, doublet stimulation resulted in a transient (approximate to 10 ms) approximate doubling of [Ca2+](i), which was accompanied by a greater force-time integral (approximate to 70%) and peak force (approximate to 40%) compared to constant frequency contractions. Moreover, doublets markedly increased force-time integral and peak force during the first 25 contractions of the fatiguing stimulation. In later stages of fatigue, addition of doublets increased force production but the increase in force production corresponded to only a minor portion of the fatigue-induced reduction in force. In conclusion, double discharges at the onset of contractions effectively increase force production, especially in early stages of fatigue. This beneficial effect occurs without additional force loss in later stages of fatigue, indicating that the additional energy cost induced by doublet discharges to skeletal muscle is limited.

    Post-exercise recovery of contractile function and endurance in humans and mice is accelerated by heating and slowed by cooling skeletal muscle2017Ingår i: Journal of Physiology, ISSN 0022-3751, E-ISSN 1469-7793, Vol. 595, nr 24, s. 7413-7426Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Key points: We investigated whether intramuscular temperature affects the acute recovery of exercise performance following fatigue-induced by endurance exercise. Mean power output was better preserved during an all-out arm-cycling exercise following a 2 h recovery period in which the upper arms were warmed to an intramuscular temperature of ˜ 38°C than when they were cooled to as low as 15°C, which suggested that recovery of exercise performance in humans is dependent on muscle temperature. Mechanisms underlying the temperature-dependent effect on recovery were studied in intact single mouse muscle fibres where we found that recovery of submaximal force and restoration of fatigue resistance was worsened by cooling (16-26°C) and improved by heating (36°C). Isolated whole mouse muscle experiments confirmed that cooling impaired muscle glycogen resynthesis. We conclude that skeletal muscle recovery from fatigue-induced by endurance exercise is impaired by cooling and improved by heating, due to changes in glycogen resynthesis rate.

    Manipulation of muscle temperature is believed to improve post-exercise recovery, with cooling being especially popular among athletes. However, it is unclear whether such temperature manipulations actually have positive effects. Accordingly, we studied the effect of muscle temperature on the acute recovery of force and fatigue resistance after endurance exercise. One hour of moderate-intensity arm cycling exercise in humans was followed by 2 h recovery in which the upper arms were either heated to 38°C, not treated (33°C), or cooled to ∼15°C. Fatigue resistance after the recovery period was assessed by performing 3 × 5 min sessions of all-out arm cycling at physiological temperature for all conditions (i.e. not heated or cooled). Power output during the all-out exercise was better maintained when muscles were heated during recovery, whereas cooling had the opposite effect. Mechanisms underlying the temperature-dependent effect on recovery were tested in mouse intact single muscle fibres, which were exposed to ∼12 min of glycogen-depleting fatiguing stimulation (350 ms tetani given at 10 s interval until force decreased to 30% of the starting force). Fibres were subsequently exposed to the same fatiguing stimulation protocol after 1-2 h of recovery at 16-36°C. Recovery of submaximal force (30 Hz), the tetanic myoplasmic free [Ca2+] (measured with the fluorescent indicator indo-1), and fatigue resistance were all impaired by cooling (16-26°C) and improved by heating (36°C). In addition, glycogen resynthesis was faster at 36°C than 26°C in whole flexor digitorum brevis muscles. We conclude that recovery from exhaustive endurance exercise is accelerated by raising and slowed by lowering muscle temperature.

    Salivary testosterone is related to self-selected training load in elite female athletes2013Ingår i: Physiology and Behavior, ISSN 0031-9384, E-ISSN 1873-507X, Vol. 116-117, s. 8-12Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Testosterone has been related to improved acute neuromuscular performance in athletic populations. It is our contention that testosterone may also contribute to improved volitional motivation and, when monitored longitudinally, may provide one proxy marker for readiness to perform. Methods: Twelve female netball players provided saliva samples prior to five standardized training sessions in which they completed a maximal-distance medicine ball throw, and then 3 sets of bench press and then back squat using a self-selected load perceived to equal a 3-repetition maximum load. Additional repetitions were encouraged when possible and total voluntary workload was calculated from the product of the load lifted and repetitions performed. Results: Relative salivary testosterone levels as a group were correlated with bench press (r = 0.8399; p = 0.0007) and squat (r = 0.6703; p = 0.0171) self-selected workload, as well as maximal medicine ball throw performance (r = 0.7062; p = 0.0103). Conclusions: Individual salivary testosterone, when viewed relatively over time, demonstrated strong relationships with self-selected workloads during an in-season training period in female netball players. As such, daily variations in testosterone may provide information regarding voluntary training motivation and readiness to perform in elite athletic populations. Psychological and behavioral aspects of testosterone may have the potential to enhance training adaptation by complementing the known anabolic and permissive properties of testosterone.

    Improving strength and power in trained athletes with 3 weeks of occlusion training2014Ingår i: International Journal of Sports Physiology and Performance, ISSN 1555-0265, E-ISSN 1555-0273, Vol. 9, nr 1, s. 166-172Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose: To examine the effects of moderate-load exercise with and without blood-flow restriction (BFR) on strength, power, and repeated-sprint ability, along with acute and chronic salivary hormonal parameters. Methods: Twenty male semiprofessional rugby union athletes were randomized to a lower-body BFR intervention (an occlusion cuff inflated to 180 mmHg worn intermittently on the proximal thighs) or a control intervention that trained without occlusion in a crossover design. Experimental sessions were performed 3 times a week for 3 wk with 5 sets of 5 repetitions of bench press, leg squat, and pull-ups performed at 70% of 1-repetition maximum. Results: Greater improvements were observed (occlusion training vs control) in bench press (5.4 ± 2.6 vs 3.3 ± 1.4 kg), squat (7.8 ± 2.1 vs 4.3 ± 1.4 kg), maximum sprint time (-0.03 ± 0.03 vs -0.01 ± 0.02 s), and leg power (168 ± 105 vs 68 ± 50 W). Greater exercise-induced salivary testosterone (ES 0.84-0.61) and cortisol responses (ES 0.65-0.20) were observed after the occlusion intervention sessions compared with the nonoccluded controls; however, the acute cortisol increases were attenuated across the training block. Conclusions: Occlusion training can potentially improve the rate of strength-training gains and fatigue resistance in trained athletes, possibly allowing greater gains from lower loading that could be of benefit during high training loads, in competitive seasons, or in a rehabilitative setting. The clear improvement in bench-press strength resulting from lower-body occlusion suggests a systemic effect of BFR training. © 2014 Human Kinetics, Inc.

    Morning based strength training improves afternoon physical performance in rugby union players2014Ingår i: Journal of Science and Medicine in Sport, ISSN 1878-1861, Vol. 17, nr 3, s. 317-321Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    ObjectivesTo determine if a morning training session could alter afternoon physical performance. Moreover, as testosterone (T) and cortisol (C) concentrations are significant predictors of physical performance, and both show circadian declines across the day, we examined the effects of morning training on diurnal T and C responses. DesignEighteen semi-professional rugby union players completed this randomised and counter-balanced study. MethodsFollowing morning saliva collection (0900. h), players completed a control (rested), Sprint (5 × 40 m) or Weights (3 repetition-maximum [RM] bench press and squat) trial. In the afternoon (15:00. h) of each trial, a further saliva sample was collected before players completed a performance test (3RM back squat and bench press, 40. m sprint, countermovement jump [CMJ]). ResultsSalivary T concentrations declined from am to pm under Control and Sprint, but not under Weights. Delta T, from am to pm, was greater under Control (-10.9±2.4pgml-1) compared to Sprints (-6.2±7.1pgml-1) and Weights (-1.2±5.5pgml-1) (p≤0.001). Delta C, from am to pm, was greater under Control compared to both Sprint and Weights (p&lt;0.05). Players elicited better CMJ peak power, 40-m time, 3RM bench and squat performance under Weights compared with Control and Sprint (p&lt;0.05). Faster 40-m times were seen under Sprint, when compared to Control (p&lt;0.05). ConclusionsPerforming morning strength training is associated with improved physical performance in the afternoon. Additionally, the circadian decline in T concentrations appeared offset by morning training. However, it is unclear if T concentrations are, in part, causal of these improved responses or simply a reflective marker. © 2013 Sports Medicine Australia.

    Individual perception of recovery is related to subsequent sprint performance2013Ingår i: British Journal of Sports Medicine, ISSN 0306-3674, E-ISSN 1473-0480, Vol. 47, nr 11, s. 705-709Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background Training recovery is vital for adaptation and performance, and to avoid cumulative fatigue and symptoms associated with overtraining. The use of cold-water immersion (CWI) as a recovery strategy is common; however, the physiological and biochemical rationale behind its use remains unclear. This study aimed to assess the relationship between body temperature responses to water immersion and individual perception of recovery, with subsequent exercise performance. Methods Twelve male rugby players participated in a 3-week cross-over trial where an intense 60 min conditioning session was followed immediately by 15 min of either 14 degrees C CWI, 30 degrees C warm-water immersion (WWI) or passive control (CON) recovery intervention. Postexercise body temperatures and subjective ratings of the recovery intervention were recorded and subsequently related to performance in a 5x40 m repeated sprint protocol undertaken 24 h later. Results CWI induced large reductions in core body temperature postimmersion (effect size (ES) range 1.05-3.21) and improved subsequent sprint performance compared to WWI (ES 1.04 +/- 0.84) and CON (ES 1.44 +/- 0.84). Both the degree of temperature decrease at 60 min postimmersion (r=0.6948; p=0.0121) and the subjective rating of the recovery intervention (r=0.5886; p=0.0441) were related to subsequent sprint performance. A very strong linear correlation was observed when these two factors were integrated (r=0.7743; p=0.0031). Conclusion A combination of physiological and psychological indices provides an improved indication of subsequent performance and suggests an important role of individual perception in enhancing training recovery.

    THREE WEEKS OF ECCENTRIC TRAINING COMBINED WITH OVERSPEED EXERCISES ENHANCES POWER AND RUNNING SPEED PERFORMANCE GAINS IN TRAINED ATHLETES2013Ingår i: Journal of Strength and Conditioning Research, ISSN 1064-8011, E-ISSN 1533-4287, Vol. 27, nr 5, s. 1280-1286Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Eccentric and overspeed training modalities are effective in improving components of muscular power. Eccentric training induces specific training adaptations relating to muscular force, whereas overspeed stimuli target the velocity component of power expression. We aimed to compare the effects of traditional or eccentric training with volume-matched training that incorporated overspeed exercises. Twenty team-sport athletes performed 4 counterbalanced 3-week training blocks consecutively as part of a preseason training period: (1) traditional resistance training; (2) eccentric-only resistance training; (3) traditional resistance training with overspeed exercises; and (4) eccentric resistance training with overspeed exercises. The overspeed exercises performed were assisted countermovement jumps and downhill running. Improvements in bench press (15.0 +/- 5.1 kg; effect size [ES]: 1.52), squat (19.5 +/- 9.1 kg; ES: 1.12), and peak power in the countermovement jump (447 +/- 248 W; ES: 0.94) were observed following the 12-week training period. Greater strength increases were observed as a result of the eccentric training modalities (ES: 0.72-1.09) with no effect of the overspeed stimuli on these measures (p > 0.05). Eccentric training with overspeed stimuli was more effective than traditional resistance training in increasing peak power in the countermovement jump (94 +/- 55 W; ES: 0.95). Eccentric training induced no beneficial training response in maximal running speed (p > 0.05); how-ever, the addition of overspeed exercises salvaged this relatively negative effect when compared with eccentric training alone (0.03 +/- 0.01 seconds; ES: 1.33). These training results achieved in 3-week training blocks suggest that it is important to target-specific aspects of both force and movement velocity to enhance functional measures of power expression.

    Male and female physical intimate partner violence and socio-economic position: a cross-sectional international multicentre study in Europe2016Ingår i: Journal of Public Health, ISSN 2198-1833, E-ISSN 1613-2238, Vol. 139, s. 44-52Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives

    This work explores the association between socio-economic position (SEP) and intimate partner violence (IPV) considering the perspectives of men and women as victims, perpetrators and as both (bidirectional).

    Study design

    Cross-sectional international multicentre study.

    Methods

    A sample of 3496 men and women, (aged 18–64 years), randomly selected from the general population of residents from six European cities was assessed: Athens; Budapest; London; Östersund; Porto; and Stuttgart. Their education (primary, secondary and university), occupation (upper white collar, lower white collar and blue collar) and unemployment duration (never, ≤12 months and >12 months) were considered as SEP indicators and physical IPV was measured with the Revised Conflict Tactics Scales.

    Results

    Past year physical IPV was declared by 17.7% of women (3.5% victims, 4.2% perpetrators and 10.0% bidirectional) and 19.8% of men (4.1% victims, 3.8% perpetrators and 11.9% bidirectional). Low educational level (primary vs university) was associated with female victimisation (adjusted odds ratio, 95% confidence interval: 3.2; 1.3–8.0) and with female bidirectional IPV (4.1, 2.4–7.1). Blue collar occupation (vs upper white) was associated with female victimisation (2.1, 1.1–4.0), female perpetration (3.0, 1.3–6.8) and female bidirectional IPV (4.0, 2.3–7.0). Unemployment duration was associated with male perpetration (>12 months of unemployment vs never unemployed: 3.8; 1.7–8.7) and with bidirectional IPV in both sex (women: 1.8, 1.2–2.7; men: 1.7, 1.0–2.8).

    Conclusions

    In these European centres, physical IPV was associated with a disadvantaged SEP. A consistent socio-economic gradient was observed in female bidirectional involvement, but victims or perpetrators-only presented gender specificities according to levels of education, occupation differentiation and unemployment duration potentially useful for designing interventions.
