    A spatial approach on tourists’ travel routes in Sweden2005Report (Other academic)
    Abstract [en]

    Bakgrund

    Destinationer och deras attraktioner har varit föremål för omfattande forskning. Detta gäller

    emellertid inte de olika förfl yttningar som görs under en resa. Förfl yttningarna görs inte bara

    till och från en destination, utan också på själva destinationen. Under de sista åren har så kalllade

    multidestinationsresor blivit allt populärare, där turister reser från en plats till en annan

    längs en resrutt.

    I denna studie har turisters olika förfl yttningar i Sverige undersökts. Som målgrupp har tyska

    bilturister valts, som utgör en av de viktigaste inkommande besöksgrupperna när det gäller

    fl erdagsresor. I studien ingår både turister som gör en rundresa genom Sverige, och de som

    bor på en och samma plats och gör dagsutfl ykter därifrån.

    Syfte och metod

    Syftet med studien är att undersöka hur typiska resrutter ser ut och vilka faktorer som påverkar

    dessa. Vidare analyseras turisternas resvana i Sverige samt resans längd. Även frågan om

    det fi nns återkommande resmönster, som sker oberoende av attraktionerna, belyses.

    Data har samlats in med hjälp av resdagböcker som 70-talet tyska bilturister skrev under sin

    resa genom Sverige. Varje dag skrev de ned hur långt de körde, var och varför de stannade

    och vilka aktiviteter de deltog i. Dessutom ritade de upp sin dagliga resrutt på en karta. Datainsamlingen

    gjordes under sommaren 2004.

    Resultat

    Resultaten visar att de fl esta turisterna reser enligt en viss rytm, oberoende av attraktioner som

    besöks. Antalet tidigare besök i Sverige påverkar inte den individuella rytmen. Däremot visar

    det sig att ett större antal tidigare besök i Sverige ökar benägenheten att resa längre norrut.

    Tiden som turisten spenderar i Sverige är en viktig faktor för dagliga förfl yttning. Turister

    som är i Sverige kortare tid reser inte kortare total körsträcka, utan kompenserar en kortare

    vistelsetid med längre dagliga körsträckor.

    Germans' tourist behaviour in Sweden2008In: Tourism, ISSN 1332-7461, Vol. 56, no 2, p. 143-158Article in journal (Refereed)
    Abstract [en]

    Tourism research has identified a number of factors that influence tourist behaviour, among them socio-demographic characteristics and the number of previous visits. This article argues that also tourists' spatial mobility, the time period within the holiday, the characteristics of the places visited, and the access to information act as important determinants for the level and choice of tourist activities. Focus in this analysis is lying on German car tourists in Sweden. For this study, a combination of methodologies is employed. This includes travel diaries on access to information as well as on type, place and length of activities, which were written by the respondents during their holiday in Sweden, and personal interviews, which were carried out after the respondents had returned home. Tourist behaviour was found to be similar to the respondents' behaviour at home, and place in combination with a limited time period and the absence of externally imposed routines was a major factor for this. In general, tourists took part in an activity for a relatively short period time before moving on. The level of spatial mobility was found to positively influence the level of tourist activity, and was to a great part responsible for the succession of activities. The time period within the holiday did not specifically influence activities, but so did access to tourist information, which affected the choice and duration of activities. Guidebooks were found to constitute the most important tourist information for the analysed tourist group.

    The importance of guidebooks for the choice of tourist sites: a study of German tourists in Sweden.2006In: Scandinavian Journal of Hospitality and Tourism, ISSN 1502-2250, E-ISSN 1502-2269, Vol. 6, no 3, p. 229-247Article in journal (Refereed)
    Abstract [en]

    Guidebooks contain important sources of information for travellers. It can be assumed that they influence the reader's choice of tourist sites, as a selection of tourist attractions is presented in the books. In this study, the influence of guidebooks on German tourists' choice of tourist sites in Sweden was examined. Nine guidebooks were analysed. In order to analyse the relationship between the presentation in the guidebooks and tourist journeys to these places, a comparison between presented tourist sites and accommodation statistics (for the year 2002) was accomplished. Further, the content of the presented tourist regions was analysed. The results indicate that the distance from home affects how strongly tourists are influenced by guidebooks. In addition, it was found that individually created tourist regions are regularly used in guidebooks and that a stereotype picture of these tourist regions is provided.

    Tourist routes: a time-geographical approach on German car-tourists in Sweden2007In: Tourism Geographies, ISSN 1461-6688, E-ISSN 1470-1340, Vol. 9, no 1, p. 64-83Article in journal (Refereed)
    Abstract [en]

    Tourism is often studied as if it was static. Yet, mobility constitutes an important part of the tourism system. The paper argues that tourists are travelling according to an individual travel rhythm, which can be defined as a travel pattern that tourists relate to, independent from the tourist sites that are visited. It was found out that there are long travel distances on the first and last day of the holiday, that mobility and stationariness are concentrated in time and that tourists along a round tour often spend the longest time in the region with the longest distance to the home region. The paper concludes that a travel rhythm exists, and that it is only partly influenced by the time the tourist spends at the destination, and the previous number of visits. Time geography was applied as underlying theory, and its use can be encouraged in forthcoming tourism studies.

    Internetgenerationen bit för bit: Representationer av IT och ungdom i ett informationssamhälle2014Doctoral thesis, monograph (Other academic)
    Abstract [en]

    The aim of this thesis is to gain a deeper understanding in relation to the construction of a ‘Net Generation’. With regards to the idea of an information society, technologies and young people are given certain positions, which are not in any sense natural but are socially constructed. This thesis explores these socially given meanings and shows what types of meanings are prioritized and legitimized. The exploration is conducted by examining, both externally and internally, given meanings of a generation identity. The external (nominal identification) in this study is understood as the construction of an abstract user and is studied by means of academic texts concerning the ‘Net Generation’. The internal (virtual identification) involves young people’s construction of their generation identity and is studied by means of collage. The collages are used to understand how the young participants position themselves in contemporary society and how they, as concrete users, articulate their relationship with information technologies.

     

    The findings show that the ‘type of behavior’ which is articulated in the signifying practice of the construction of the abstract user, ‘Net Generation’, reduces users and technology to a marketing / economical discourse. In addition the idea of the abstract user implies that all users have the same possibilities to achieve ‘success’ in the information society, by being active ‘prosumers’. The concrete users articulate that they feel stressed and pressured in relation to all the choices that they are expected to make. In this sense, the participants do not articulate the (economical) interests as assumed for the ‘Net Generation’, but, rather articulate interests to play, to have a hobby and be social when using information technologies.

     

    What this thesis thus proposes, is to critically explore the ‘taken for granted’ notions of a technological order in society as pertaining to young people. Only if we understand how socially given meaning is constructed can we break loose from the temporarily prioritized values to which the position of technology and users are fixed.

    Not so ‘techno-savvy’: Challenging the stereotypical images of the ‘Net generation’2009In: Digital Culture & Education, ISSN 1836-8301, E-ISSN 1836-8301, Vol. 1, no 2, p. 129-144Article in journal (Refereed)
    Abstract [en]

    It is often argued that young people growing up in the presence of the Internet and new media are ‘techno savvy’. They are often distinguished as a new generation because of their relationship with new media,which is assumed to be considerably different, in comparison, to older generations. This new generation has also been characterized as the ‘Net generation’ (Tapscott, 1998). However the stereotypical images of ‘net geners’—being technologically savvy—have rarely been questioned. This article aims at nuancing these images with the objective of exploring the stereotypical images, rather than proving if the images are true or false. By using a statistical representative study of Swedish people’s Internet behaviour and linking the results to an analytical frame of Internet skills, the question, “what is it young people know when it comes to the Internet use and how is it related to the stereotypical image of the ´Net generation’?” is explored. The main findings suggest that various Internet activities differ by age and few activities could be ascribed solely to the so-called ‘Net generation’.

    OPENING THE BOX: Exploring the presumptions about the 'Net Generation'2010Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    There are many names or labels which refer to the generation growing up with digital media and these include labels such as ‘Net Generation’ (Tapscott, 1998), ‘digital natives’ (Prensky, 2001), ‘cyberkids’ (Holloway, 2003) and ‘MySpacegeneration’ (Rosen, 2008). The core idea behind these labels is that young people who have grown up surrounded by digital technology are very different to previous generations in their way of using and even thinking about the new digital technology. This appears to be reinforcing a generational divide and makes the assumption that young people can be categorized into one group in relation to their use of ICTs. The approach in this thesis is to empirically explore, in order to nuance, some of these presumptions about the ‘Net Generation’ (defined according to Tapscott). Thus, the research question is: How can the presumptions about the ‘Net Generation’ be nuanced?

    The following three presumptions have been explored within the three papers included in the thesis: i) The ‘Net Generation’ diverges from previous generations in relation to the use of internet; ii) The ‘Net Generation’ is techno-savvy or digitally competent; iii) The digitally competent ‘Net Geners’ are also digital participants since there is a causal relationship between digital competence and digital participation. The explorations are conducted by using the theoretical concepts ‘digital skills’, ‘self-efficacy’ and ‘participatory culture’. Several hypotheses,deduced from previous research, have been tested on a national representative sample of people born between the years 1978 and 1997 (categorised as the ‘Net Generation’). The results show that ‘Net Geners’ internet usage is diversified;hence, it is simplified to talk about them as a homogeneous group. Those included in the categorisation have different opportunities to participate in the digital society. Their internet usage differs both in terms of how much time they spend and what they do online. Their digital skills and self-efficacy in the use of computers are also different and so is the perceived feeling of participation in the information society. This implies that the ‘Net Geners’ do not have equal conditions in relation to participation in the digital society. However, what is meant by participation is still an unresolved question which requires further exploration.

    Predicting the participation in information society2011In: Interactive Media Use and Youth: Learning, Knowledge Exchange and Behavior, IGI Global, 2011, p. 207-221Chapter in book (Other academic)
    Abstract [en]

    The approach in this chapter is to recognize what is said to be important regarding the feeling of participation in the information society. The perceived feeling of participation is assumed to be an important indicator for young people's online experiences. In previous research, digital skills and other related concepts such as self-efficacy and a relationship with technology are shown to be important in order to be able to participate in the information society. In this case, there is an exploration into the amount that social factors, digital skills, self-efficacy and a relationship with technology are able to explain the variance in perceived feelings regarding participation. It has been determined that education, selfefficacy, instrumental computer skills, information skills and strategic skills can explain 22 percent of the variance in the perceived feeling of participation. This implies that young people themselves might define other factors as being more important with regards to participation in the information society.

    Ungdomar i Härnösand - åsikter och attityder: LUPP - lokal uppföljning av ungdomspolitiken2016Report (Other academic)
    Abstract [sv]

    Myndigheten för Ungdoms och Civilsamhällesfrågor MUCF (tidigare Ungdoms-styrelsen) har utvecklat Lupp-enkäten - Lokal uppföljning av ungdomspolitiken som ett verktyg för kommunernas ungdomspolitiska arbete. Tanken är att kommunerna på ett enkelt sätt ska kunna ta reda på hur ungas situation ser ut lokalt och utveckla en effektiv ungdomspolitik som bygger på samarbete mellan olika sektorer.Denna rapport är produkten av Härnösand kommuns analys av enkätsvaren från ungdomar i årskurs 8 på högstadiet och gymnasiets år 2. I lupp besvarar ungdomar frågor som är indelande i sju tematiska avsnitt – fritid; skola; politik och samhälle; trygghet; hälsa; arbete och framtid. I rapporten tillämpas ett normkritiskt ung-domsperspektiv. Det innebär bland annat att resultaten, det vill säga ungdomars svar, analytiskt ställs i relation till dominerande föreställningar som finns om unga och föreställningar om relationen mellan ungdom och vuxen. I denna rapport be-traktas inte kategorierna ungdom och vuxen som naturligt givna utan snarare som konstruktioner inbäddade i samhällets strukturer.Delaktighet är ett genomgående tema i rapporten som diskuteras främst utifrån vilka möjligheter ungdomar har till delaktighet och inflytande. Med möjligheter av-ses de yttre ramarna eller förutsättningarna att inkluderas, att få vara delaktig och göra sin röst hörd.Rapporten innehåller åtta kapitel som består av en inledning, en redogörelse för ur-val och genomförande och därefter kapitel som fokuserar på specifika teman som omfattas av luppundersökningen.

    Abstract [sv]

    Myndigheten för Ungdoms och Civilsamhällesfrågor MUCF (tidigare Ungdoms-styrelsen) har utvecklat Lupp-enkäten - Lokal uppföljning av ungdomspolitiken som ett verktyg för kommunernas ungdomspolitiska arbete. Tanken är att kommunerna på ett enkelt sätt ska kunna ta reda på hur ungas situation ser ut lokalt och utveckla en effektiv ungdomspolitik som bygger på samarbete mellan olika sektorer. Denna rapport är produkten av Ånge kommuns analys av enkätsvaren från ungdomar i årskurs 8 på högstadiet och gymnasiets år 2.

I rapporten tillämpas ett normkritiskt ungdomsperspektiv. Det innebär bland annat att resultaten, det vill säga ungdomars svar, analytiskt ställs i relation till dominerande föreställningar som finns om unga och föreställningar om relationen mellan ungdom och vuxen. I denna rapport betraktas inte kategorierna ungdom och vuxen som naturligt givna utan snarare som konstruktioner inbäddade i samhällets strukturer. Delaktighet är ett genomgående tema i rapporten som diskuteras främst utifrån vilka möjligheter ungdomar har till delaktighet och inflytande.

    Body growth of noble crayfish (Astacus astacus) after reintroduction to a northern river (Ljungan, Sweden)Manuscript (preprint) (Other academic)
    Abstract [en]

    Noble crayfish were introduced to the River Ljungan as part of a reintroduction program. Crayfish were caught at five sites and individually marked with passive integrated transponders (PIT-tags). At each sampling occasion, the crayfish were sexed and their total lengths measured before being released to the same spot where they were captured. The size structure and growth rates were compared between the different sites and a linear growth model was developed from recapture data. The analysis revealed that crayfish moulted once annually with length increments close to the maximum that is reported for the species. The relative growth increment of males was 20% greater than for females. The growth and size of the length increment were not associated to different habitats or water temperature at the sites. Growth was also measured in the River Ljungan in the 1960s. When compared to the conditions from the 1960s, it could not be precluded whether the differences in climate or population density from that time had a positive effect on the body size growth rate as observed today. A conclusion from this study is that noble crayfish have ability to grow just fast as at its southern locations as the northern edge of its distribution area.

    Noble Crayfish (Astacus astacus) in a Changing World: Implications for Management2012Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The noble crayfish (Astacus astacus) is critically endangered in Sweden. This is mainly due to the crayfish plague (Aphanomyces astaci), a lethal disease that, among other things, can be spread through the stocking of fish from contaminated water or contaminated fishing gear. The largest single propagation path is the illegal introduction of infected signal crayfish (Pacifastacus leniusculus). A conservation measure for crayfish is to re-introduce it to where it has a chance to survive, though a sustainable, locally regulated fishing can also serve as an indirect protection for the species. When the local inhabitants are allowed to keep their fishing culture and when fishing is acceptable, the incentive for illegal stocking of signal crayfish is low. However, it is important to avoid overfishing because the recovery, especially in the northern regions, can take several years. Therefore, it is important to know how crayfish respond long-term to fishing and environmental factors.

    Crayfish populations became extinct in the River Ljungan for unknown reasons in 1999. The water flow of the river has been used for activities such as fishing, timber transport and hydroelectric power since the 1500s, and the noble crayfish has been part of the fauna since the last century. The River Ljungan was known as one of Sweden's best fishing areas for crayfish and fishing became an important part of the local tradition. When the crayfish populations became extinct, a reintroduction program was a natural step, and crayfish are nowadays re-established in the river.

    From 1963 to 1990 the Swedish Board of Fisheries collected data from crayfish fishing in the River Ljungan to determine the economic damage to fishery owners caused by the construction of a power plant. After each season the fishermen reported the catch. In this thesis, the data was used to investigate which factors influence the long-term size of the crayfish catch and how the crayfish catches were affected by the power plant building. After re-introduction of the crayfish to the River Ljungan, the local fishermen monitored the population development in a simple, standardized way. To examine the validity of their measurements and to investigate the body growth of the individuals, a capture-recapture technique with a permanent marking of the crayfish was used.

    The crayfish catches were primarily impacted by the previous years' catch size, and a large catch the previous year resulted in a reduced catch the following year. A mild winter climate (NAO-index > -0.7) six years before the catch implied a large catch, whereas a high water flow during the autumn or spring (>95m3s-1) two years before the catch, implied a poor catch. Major habitat changes in the form of greatly reduced water flow (~90%) were negative for crayfish catches. The standardized method of fishing used by the local fishermen to monitor the development of the crayfish population was precise enough to detect population trends and this method can therefore be recommended to monitor future re-introductions of crayfish. Although the River Ljungan is located at the northern edge of the species' range, noble crayfish in the river presently have a body growth rate that is close to the maximum measured for crayfish (8 mm/moult for females and 10 mm/moult for males).

    Based on the results, the most important advice for sustainable fisheries in Ljungan and other northern rivers is to:

    • Monitor the population trends, NAO-index and water flow in May and October. 
    • Use the results from the monitoring to determine the number of allowed fishing days and traps.
    • Collect data about the catch size and efforts from legal fishing and use it to evaluate the sustainability of the fishing.
    • Enhance the buildup of the harvestable cohort by

    -saving reproductive females

    -introduce a size limit of 10 cm

    -provide proper shelters for the non-harvestable cohort.

    Slutrapport Förstudie för Älvens Hus: Ett LEADER-projekt i samarbete med Mittuniversitetet, Ånge kommun, 16 lokala fiskevårdsområden och en entreprenör2011Report (Other (popular science, discussion, etc.))
    Abstract [sv]

    Arbetet med förstudie för ”Älvens Hus” visar att det går att överbrygga både läns- och kommungränser när det gäller fiske. Det går att diskutera förvaltningsfrågor över gränserna. Arbetet visar också att det finns ett behov av lättförståelig information och utbildning om hur man förvaltar den utrotningshotade flodkräftan. Projektet har visat att det finns förutsättningar i vår region för att utveckla en uthållig, ekologisk verksamhet kring flodkräftan och fiske, men att det saknas entreprenörer i form av kunniga fiskeguider som kan länka samman deltagare, fiskevårdsområden och besöksnäring. Projektet har visat att naturum Ånge kan arbeta tematiskt över ett vidare geografiskt område och vara ett fönster för hela Mittlandregionen samt att naturum Ånge behöver förnya sin utställning för att klara detta. Projektet har visat att naturum Ånge har behov av att inleda nya samarbeten; både av ekonomisk och av kunskapsmässig natur. Detta är ett tidsödande arbete, men nödvändigt för att få till stånd en utveckling.

    De erfarenheter vi har fått i projektet visar att det är viktigt att låta samverkan och nätverksbyggande ta tid. Det tar tid att bygga upp förtroende. Vår projekttid på ett och ett halvt år var tillräcklig när det gällde fiskevårdsområdena, men för att inleda nya samarbeten för naturum Ånge var tiden för kort.

    Projektet har fört samman fiskevårdsområden från hela regionen i ett gemensamt nätverk och bidragit till ökad kunskap om flodkräftan till en bredare allmänhet genom ”Kräftkokbok – om konsten att sköta ett kräftvatten”. Projektet har också bidragit till att naturum Ånge får behålla sin status som naturum och att det kommer anläggas en naturstig med vatten- och kräfttema i anslutning till naturum Ånge.

    Time series analysis of climate-related factors and their impact on a red-listed noble crayfish population in northern Sweden2012In: Freshwater Biology, ISSN 0046-5070, E-ISSN 1365-2427, Vol. 57, no 5, p. 1031-1041Article in journal (Refereed)
    Abstract [en]

    1. Global climate change is predicted to raise water temperatures and alter flow regimes in northern river systems. Climate-related factors might have profound impacts on survival, reproduction and distribution of freshwater species such as red-listed noble crayfish (Astacus astacus) in its northern limit of distribution.2. In this study, noble crayfish capture data over 27 years from the River Ljungan, Sweden, were examined. Time series of catch per unit effort (CPUE) were analysed in relation to the North Atlantic Oscillation (NAO) index, regional weather factors and water flow. CPUE was assumed to reflect differences in population size. Two models were constructed to explore the relative impact of different climate factors and density dependence on variability of catch sizes.3. The most parsimonious model for CPUE time series, explaining 72% of the variance in CPUE, included density-dependent population dynamics of the crayfish and climate or weather factors. The specific effect from density dependence in the model was 37%, while climate/weather factors contributed with 35% of the variation. The most important climate/weather factors are variations in NAO index and water flow. Temperature did not improve the model fit to capture data.4. The best model was evaluated using independent data sets that gave correlations between model predictions and data ranging from 0.44 to 0.53. The density dependence shows a time lag of 1 year, while climate variables show time lags from 2 to 6 years in relation to CPUE, indicating effects on different cohorts of the crayfish population.5. Both density dependence and climatic factors play a significant role in population fluctuations of noble crayfish. A 6-year time lag for NAO index is puzzling but indicates that some as yet unidentified factors related to NAO might act on the juvenile stages of the population. Water flow shows a 2-year lag to the CPUE, and high flow in the river may affect adult survival. The reasons for fluctuation of crayfish catches in response to climate need to be identified, and fishing quotas should consider the different cohort sizes because of variation in environment. Reintroduction programmes for crayfish need to consider effects of climate change when designing management strategies.

    Abstract [en]

    Catch per unit effort (CPUE) is used as a standardized trapping method by local fishermen and in monitoring studies. In this study, CPUE was compared with population estimates made with a capture-recapture method based on the passive integrated transponder (PIT-tag) marking of individuals. The results show a stronger positive correlation between the estimated population sizes from the capture-recapture method with an estimated CPUE effort of 120 traps. The fishermen used 15 traps, and even this effort showed a fair correlation with the mark-recapture estimates. This indicates that the standardized way of trapping with 15 traps can be used to evaluate reintroduction programs and monitor crayfish populations

    Free-flowing water is thought to be of importance for reproduction and body growth of noble crayfish, Astacus astacus (Linnaeus), in the northern edge of its distribution area. A hydroelectric power plant with a bypass tunnel was built in the River Ljungan, Sweden, in 1976. This reduced the mean water flow in the old river bed from about 60 m3 s-1 to 3 m3 s-1. The sites with the largest reduction of water flow had the largest decline in catch per unit effort of crayfish. At one site the catches were reduced by > 60%, but the catch success varied between locations. At all sites, water regulation seemed to have an effect, even though catch per unit effort was possibly affected by a number of other factors. © 2010 International Association of Astacology.

    Free-flowing water is thought to be of importance for reproduction and body growth of noble crayfish (Astacus astacus (Linné)) in the northern edge of its distribution area.

    A hydroelectric power plant with a bypass tunnel was built in the river Ljungan in 1976.  This reduced the mean water flow in the old river bed from about 60m3/s to 3m3/s. The sites with the largest reduction of water flow had the largest decline in catch per unit effort of crayfish.  At one site the catches were reduced by >60%, but the catch success varied between locations.  In all sites the regulation seemed to have an effect, even though catch per unit effort was possibly affected by a number of other factors.

    The meaning of risk-taking – key concepts and dimensions2017In: Journal of Risk Research, ISSN 1366-9877, E-ISSN 1466-4461Article in journal (Refereed)
    Abstract [en]

    Dealing with and taking risks are central issues of current societies which had been characterised by heightened debates and conflicts about risk (Beck, Giddens). Even though there is good knowledge available, policies and strategies to reduce people’s risk-taking are often less successful than expected. Experts are puzzled about common people not following good advice presuming people’s lack of understanding. While this might be true in many cases a growing body of research shows, rather than being merely ignorant or misinformed, people often have good knowledge when taking risks. A growing body of research provides knowledge about the complexities, dynamics and contradictions of people’s risk-taking. However, there have been little attempts to systematise this body of knowledge. This article contributes to such an enterprise. It suggests distinguishing between different motives for risk-taking, different levels of control and a number of ways how reflexivity about risk is rooted in the social realm. It also explores how risk-taking is part of developing and protecting a valued identity. The article concludes, across different domains there is good evidence for how structural and cultural forces combine and shape risk-taking while people take risks to develop a valued identity and to protect it. Advancing expert’s understanding of risk-taking and change people’s risk-taking require considering and approaching the larger social contexts and individual risk practices in everyday life.

    Exposure to a combination of heat and hyperoxia during cycling at submaximal intensity does not alter thermoregulatory responses2016In: Biology of Sport, ISSN 0860-021X, E-ISSN 2083-1862, Vol. 33, no 1, p. 71-76Article in journal (Refereed)
    Abstract [en]

    In this study, we tested the hypothesis that breathing hyperoxic air (FinO2 = 0.40) while exercising in a hot environment exerts negative effects on the total tissue level of haemoglobin concentration (tHb); core (T-core) and skin (T-skin) temperatures; muscle activity; heart rate; blood concentration of lactate; pH; partial pressure of oxygen (PaO2) and carbon dioxide; arterial oxygen saturation (SaO2); and perceptual responses. Ten well-trained male athletes cycled at submaximal intensity at 21 degrees C or 33 degrees C in randomized order: first for 20 min while breathing normal air (FinO2 = 0.21) and then 10 min with FinO2 = 0.40 (HOX). At both temperatures, SaO2 and PaO2, but not tHb, were increased by HOX. Tskin and perception of exertion and thermal discomfort were higher at 33 degrees C than 21 degrees C (p < 0.01), but independent of FinO2. Tcore and muscle activity were the same under all conditions (p > 0.07). Blood lactate and heart rate were higher at 33 degrees C than 21 degrees C. In conclusion, during 30 min of submaximal cycling at 21 degrees C or 33 degrees C, T-core, T-skin and T-body, tHb, muscle activity and ratings of perceived exertion and thermal discomfort were the same under normoxic and hyperoxic conditions. Accordingly, breathing hyperoxic air (FinO2 = 0.40) did not affect thermoregulation under these conditions.

    Effect of resistance training with vibration and compression on the formation of muscle and bone2017In: Muscle and Nerve, ISSN 0148-639X, E-ISSN 1097-4598, Vol. 56, no 6, p. 1137-1142Article in journal (Refereed)
    Abstract [en]

    IntroductionIn this study we investigated the effects of resistance training with vibration in combination with leg compression to restrict blood flow on strength, muscle oxygenation, muscle mass, and bone formation. MethodsTwelve participants were tested before and after 12 weeks of resistance training with application of vibration (VIBRA; 1-2mm, 30Hz) to both legs and compression (approximate to 35mm Hg, VIBRA+COMP) to only 1 leg. ResultsVIBRA+COMP and VIBRA improved 1 repetition maximum (1-RM), increased the number of repetitions preceding muscle exhaustion, enhanced cortical bone mass, and lowered the mass and fat fraction in the thigh, with no changes in total muscle mass. The mass of cancellous bone decreased to a similar extent after VIBRA and VIBRA+COMP. DiscussionResistance training with VIBRA+COMP and VIBRA improved 1-RM, increased the number of repetitions preceding muscular exhaustion, and enhanced formation of cortical bone, with no alteration of muscle mass.

    Influence of Hypoxic Interval Training and Hyperoxic Recovery on Muscle Activation and Oxygenation in Connection with Double-Poling Exercise2015In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 10, no 10, article id e0140616Article in journal (Refereed)
    Abstract [en]

    Here, we evaluated the influence of breathing oxygen at different partial pressures during recovery from exercise on performance at sea-level and a simulated altitude of 1800 m, as reflected in activation of different upper body muscles, and oxygenation of the m. triceps brachii. Ten well-trained, male endurance athletes (25.3 +/- 4.1 yrs; 179.2 +/- 4.5 cm; 74.2 +/- 3.4 kg) performed four test trials, each involving three 3-min sessions on a double-poling ergometer with 3-min intervals of recovery. One trial was conducted entirely under normoxic (No) and another under hypoxic conditions (Ho; FiO2 = 0.165). In the third and fourth trials, the exercise was performed in normoxia and hypoxia, respectively, with hyperoxic recovery (HOX; FiO2 = 1.00) in both cases. Arterial hemoglobin saturation was higher under the two HOX conditions than without HOX (p<0.05). Integrated muscle electrical activity was not influenced by the oxygen content (best d = 0.51). Furthermore, the only difference in tissue saturation index measured via near-infrared spectroscopy observed was between the recovery periods during the NoNo and HoHOX interventions (P<0.05, d = 0.93). In the case of HoHo the athletes' P-mean declined from the first to the third interval (P < 0.05), whereas P-mean was unaltered under the HoHOX, NoHOX and NoNo conditions. We conclude that the less pronounced decline in P-mean during 3 x 3-min double-poling sprints in normoxia and hypoxia with hyperoxic recovery is not related to changes inmuscle activity or oxygenation. Moreover, we conclude that hyperoxia (FiO2 = 1.00) used in conjunction with hypoxic or normoxic work intervals may serve as an effective aid when inhaled during the subsequent recovery intervals.
