    Physical education - educating bodies after postmodernism?2018In: Educational Philosophy and Theory, ISSN 0013-1857, E-ISSN 1469-5812, Vol. 50, no 14, p. 1435-1436Article in journal (Refereed)
    Abstract [en]

    The article offers the author's perspective about what comes after postmodernism and how it affects educational philosophy and theory, focusing on physical education (PE) in schools. The author argues that the adoption of the idea of performative pedagogies as a way to elicit social change also indicates adoption of movement. Education insights about bodies and embodiment from the case of Indian sprinter Dutee Chand are noted.

    Vägen till återhämtning- Stressrelaterad ohälsa & överträning/överträningssyndrom till utmattningssyndrom: En intervjustudie: konsensus i begrepp, diagnostisering och behandling2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis

    ABSTRACT

    Aim: The aim of this study was to get a more precise definition, diagnosis and treatment of the phenomenon stress related illness and the process to exhaustion. Stress related illness covers the term overtraining syndrome (OTS) which is a common problem in elite sports. Experts, clinics and health workers in Sweden have been interviewed. By recognizing early signals, stress related illness may be dealt with an earlier treatment which leads to a better prognosis. Stress related illness and OTS can be a long-lasting process before exhaustion comes. Sports and work give the same stress to our bodies and minds. Different treatments of the clients were investigated in this study.

    Method: The method chosen was a quality study with semi structural interviews that investigate these phenomenon’s. Five experts (three in clinics who regularly sets diagnosis) and five health workers (two in clinics who regularly sets diagnosis) were interviewed. Terms were developed after the aim and the interviews were recorded. Systematic text condensation (STC) was used for the analysis.

    Results: Six codes were found after the analysis. 1.” The capacity of understanding the process”. The patient must admit his problem in order to be able to treat it. 2.” Defining stress related illnesses”. A finer grade of definitions will aid psychologists and doctors to set a certain diagnosis. 3.” The preemptive work is the treatment”. The best treatment is to find it at an early stage. 4.” The road to recovery” visualizes the entire course, from the first symptoms, to treatment and finally recovery. 5.” Challenges of the future”. The highest virtues in our society today are efficiency and performance. In itself those are great and should be revered, but as all things in extreme they can be dangerous. Education is vital if we want to avoid these problems in the future. 6.” Recovery”. When examining and diagnosing stress related illnesses, attention to recovery should always be your first and foremost concern.

    Conclusions: The definition of stress related illness is still too broad and covers a large field. Cases regarding these kind of illnesses differs and is highly individual. Exhaustion may occur quickly or not at all. The goal should be to coordinate with the rest of Europe to get a joint medical diagnosis. As it is now, definitions and treatments vary even inside of Sweden. If the knowledge regarding stress would be more widespread, exhaustion could be avoided. One should strive to identify the symptoms at an early stage to prevent them becoming severe. OTS should be picked up by health workers in their daily work and not only as a term in elite sports.

    Ger fysisk aktivitet bättre studieresultat?: En enkätundersökning om samband mellan fysisk aktivitet och studieresultat2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte och frågeställningar

    Syftet med studien är att undersöka eventuella samband mellan fysisk aktivitet och studieresultat hos elever i årskurs nio i en skola utanför Stockholm. I syfte att utföra detta användes följande frågeställning:

    ● Ger en ökad mängd fysisk aktivitet ett högre meritvärde hos elever i årskurs nio?

    Metod Studien är baserad på en enkätundersökning besvarad av 71 deltagare från tre klasser i årskurs nio på en skola utanför Stockholm. Enkäten innehåller frågor om elevens mängd av fysisk träning, fysisk aktivitet och stillasittande samt en fråga om elevens totala meritvärde från terminen innan. Eleverna fick själva uppskatta mängden tid de spenderade på de olika aktiviteterna. Elevernas meritvärden kontrollerades med skolans betygskatalog för att säkerställa att rätt meritvärde var angivet.

    Resultat Resultatet visade inget samband mellan fysisk aktivitet och studieresultat i form av ökat meritvärde. Det kunde heller inte påvisas något samband mellan fysisk träning och studieresultat. Däremot upptäcktes ett medelstarkt samband mellan ett ökat stillasittande och ett ökat meritvärde.SlutsatsDenna undersökning har inte påvisat något samband mellan fysisk aktivitet och studieresultat hos den undersökta populationen.

    Governance of local sports policy: A Swedish case study in the post-NPM era

    Aim

    This study is about the distribution of public sport resources in Sweden since 1985 on the local level. A motive is that earlier research has not univocally been able to show if the socioeconomic transformations in society, the change of ideas about how to arrange and govern it, and implemented policy has made any difference for the actual outcome of sport policies.

    The aim is to analyze the governance of public resource allocation to sport in Stockholm city 1985-2017 and its consequences. The research questions are as follows:

    -          How is the resources distributed?

    • How much resources and what resources are distributed?
    • In what ways are they distributed?
    • To whom are they distributed?

    -          Which principles are the basis for resource allocation?

    • What are the guidelines of the decision makers and what are the underlying norms and values?

    -          How are the guiding decisions taken and how are they implemented?

    • Who and what is involved and effect resource allocation, i.e. which actors participate in the decisions, who implement them and what structures affect them?

    Theoretical background and literature review

    The analytical approach starts within historical and political science and research of societal governing. Three forms of political social governing are scrutinized: hierarchic governing, discursive governing and interactive governing. The concept governing is stipulated as a long-term impact that brings on certain specific effects.

    The changes during the last three to four decades that have influenced sport policies on a national level has been thoroughly described. From the beginning of the 1990s, sport scientists discern a gradual change in the stately view of the sport movement’s societal role. They refer among other things to new general principles regarding the governing of aims and results in Swedish administration, and also to more cooperation and trust between governmental actors and to a rapidly growing element of aimed public project funding.[1] At the same time though it is pointed out that “the greater part of sport support today lies within the appropriation of ‘common nature’ that RF has at its independent disposal”, and that ”the state /…/ has avoided political pressure regarding regulation and normative development of sport clubs and federations”.[2]

    The centralized attempts to control have, as earlier on in history, mainly been in form of expressed wishes and interests – not regulations and sanctions. The matter of a new basis for negotiations and its penetration in practice can thereby only be settled empirically.   

    Research design, methodology and data analysis

    The method is a case study of Stockholm city. The empirical data is collected from meeting minutes and decision protocols from the public sports authority, contemporary literature and recorded and transcribed interviews with representatives of politics and public administration. The interviews are qualitative and semi-structured.

    The data consists of leading decisions, i.e. those decisions that – in retrospect – can be seen as indicative on how the public sport resources should be (and have been) used. It could be long-term policy decisions or more direct, acting decisions. Mainly it is decisions and acting on support for sporting facilities and sport clubs that is being analyzed. The concept of support refers mainly to financial support.

    Results/findings and discussion

    The survey about the governing forms and practices indicates, that a lot of different shapes and practices have been used for a long time working parallel as a complement to each other rather than succeeding (replacing) each other.

    Primary results regarding the accomplished sport politics, i.e. the sport policy and administration-effects and consequences, are in the first place that the allowance of public funds to sports has increased during the period. Secondly that the resources are distributed in mainly the same ways (channels) as before and that there are mainly the same physical activities, organizations and social groups as before that are favoured – while others in comparison are disadvantaged. This is a fact in spite of that the politicians since quite a long time are fully aware of which groups have been neglected when it comes to physical activities, what kind of new desires citizens have today, and that there are many new initiatives from public authorities time and again to bring about a change.

    Conclusion, contribution and implications

    The conclusion reads that the structural elements economy, tradition (worked up systems and routine procedures) and culture (normed/standardized behaviours) have influenced the shaping of sports policy after 1985 more than individual actors and their articulated interests and expressed values. A fact is also that politicians and civil servants have a main responsibility regarding the implemented policies, but that they at the same time are forced to take into consideration the investments already done and the economic reality that reigns here and now.

    Interestingly enough international research often come to similar conclusions, which shows that there is much to gain by comparisons on procedures and outcomes of public sport support. Obviously there is local sports policy with high ambitions all around Europe. At the same time economic ideas, established structures and strong traditions often set more or less distinct limits of what could be done.

    The contribution this article provides concerns details on how the leading decisions are taken, by whom and why. The article also elaborates on the routines that make the setting for the civil servants in the local public sport administration and the cultures/traditions that influences the representatives in the public sport authority as well as the employees in the administration.

    The effect of a reduced first step width on starting block and first stance power and impulses during an athletic sprint start.2018In: Journal of Sports Sciences, ISSN 0264-0414, E-ISSN 1466-447X, p. 1-9Article in journal (Refereed)
    Abstract [en]

    This study investigated how manipulating first step width affects 3D external force production, centre of mass (CoM) motion and performance in athletic sprinting. Eight male and 2 female competitive sprinters (100m PB: 11.03 ± 0.36 s male and 11.6 ± 0.45 s female) performed 10 maximal effort block starts. External force and three-dimensional kinematics were recorded in both the block and first stance phases. Five trials were performed with the athletes performing their preferred technique (Skating) and five trials with the athletes running inside a 0.3 m lane (Narrow). By reducing step width from a mean of 0.31 ± 0.06 m (Skating) to 0.19 ± 0.03 m (Narrow), reductions were found between the two styles in medial block and medial 1st stance impulses, 1st stance anterior toe-off velocity and mediolateral motion of the CoM. No differences were found in block time, step length, stance time, average net resultant force vector, net anteroposterior impulse nor normalised external power. Step width correlated positively with medial impulse but not with braking nor net anteroposterior impulse. Despite less medially directed forces and less mediolateral motion of the CoM in the Narrow trials, no immediate improvement to performance was found by restricting step width.

    The Transtemporality of Online Performance2016In: Performance Research, ISSN 1352-8165, E-ISSN 1469-9990, Vol. 21, no 5, p. 107-110Article in journal (Refereed)
    Abstract [en]

    This article examines notions of temporality of online performance as a way to rethink earlier debates about performance ontologies. Today, online, and increasingly mobile, technological activities such as photo and video sharing, instant messaging, blogging and social networking organise around performance practitioners' day-to-day existence. In this networked society, performances are constantly mediated through the prism of myriads of digital platforms. Because performances are enacted within or supported by digitally mediated networks and, this is crucial, they incessantly expand temporally, I will refer to online performance in terms of transtemporality, rather than depend on an ontology of unmediation and presence. I depart from Rebecca Schneider's Performance Remains (2011) where she argues how notions of performance, reiteration and documentation are intertwined and contingent, and from the recent performative answers to the logic of the archive found in Amelia Jones's and Adrian Heathfield's anthology Perform Repeat Record: Live Art in History (2012). I argue, by illustrations of Adam Weinert's performance work (2013-2014) as well as my own (2010-2012), that online performance is never fully present but immanently distended through remediation. Performances participate in inherently ruptured transtemporal networks (tweets, reperformances, blogging, video sharing) through which they are continuously remediated and transformed. I propose that online performance even might suggest that performance continuously escapes a sense of Being. Performance's ontology, or rather its ontogenesis proposed by Heathfield (2012), resides with the elements of transformation inherent in its online remediations.

    Baseball, glima and Gotlandic sport: An analysis of the demonstration sports in the 1912 Stockholm Olympics2018In: Diagoras: International Academic Journal on Olympic Studies, Vol. 2, p. 103-122Article in journal (Refereed)
    Abstract [en]

    The purpose of the study is to analyse the demonstration sports (baseball, glima and Gotlandic sport) into the 1912 Stockholm Olympics. Who took the initiative for the demonstration sports? The IOC or the Swedish Organising Committee? How were the demonstration sports received by the public and the press, and what was their legacy? The study is based mainly on primary sources from the 1912 Stockholm Olympics’ archive. The 1912 Stockholm Olympics has been well explored, mainly by Swedes and internationals, and this gives a good picture of the 1912 Stockholm Olympics from different perspectives. On the other hand, research into the demonstration sports in the Olympic Games is clearly limited and there is thus a great need for further studies. This current study covers just a small part of this need. The results show that in 1912 there was no considered strategy on the part of either the IOC or the Swedish Organising Committee concerning the demonstration sports. The initiative for the demonstration sports came from individual representatives of each type of sport, and the Swedish organisers were positive towards three of those proposed: baseball, glima and Gotlandic sport. The Swedish organisers had control over which demonstration sports would be included in the programme. This meant that the choice of demonstration sports lay beyond the control of the 1912 IOC, but this would change in the 1900s. During the games they were given limited attention at most, both publicly and in the press. The demonstration sports were removed from the Olympic programme before the 1992 Olympic Games.

    National injury prevention measures in team sports should focus on knee, head, and severe upper limb injuries.2018In: Knee Surgery, Sports Traumatology, Arthroscopy, ISSN 0942-2056, E-ISSN 1433-7347Article in journal (Refereed)
    Abstract [en]

    PURPOSE: To examine acute injuries in licensed floorball, football, handball, and ice hockey players in all ages nationwide in Sweden, and to identify the most common and severe injuries in each body location and recommend injury prevention measures.

    METHODS: Using national sport insurance data from years 2006-2015 was the incidence and proportion of acute injuries, and injuries leading to permanent medical impairment (PMI), calculated in the four team sports. The most common injury type and injured body part was identified, with a particular focus of the severe injuries. Comparison between sexes was made.

    RESULTS: In total, there were 92,162 registered injuries in all sports together. Knee injuries were most common, and also had the highest incidence of PMI, in all ball sports and in female ice hockey players. In male ice hockey, the most common injury was a dental and face injury, and PMI injuries were mostly in the shoulder. The most severe PMI injuries were rare and most often a face/eye injury in male floorball and ice hockey, a concussion in female ice hockey, and a knee injury in female floorball, and in both sexes in football and handball.

    CONCLUSIONS: To achieve the greatest impact in reducing the adverse effects of acute sport injuries nationwide in Sweden, preventive measures should focus on knee injuries in all the investigated team sports. The severe head/face and upper limb injuries also need attention. Protective equipment, neuromuscular training programs, rules enforcements, and fair-play interventions may reduce the incidence of injuries.

    Omklädningsrummet: En studie om elevers uppfattning om miljön i omklädningsrummet2018Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning

    Syfte och frågeställningar

    Syftet med denna undersökning är att ta reda på vad elever i årskurs 7-9 har för åsikter om miljön i omklädningsrummet som används i samband med idrott och hälsa samt vilka faktorer som gör att vissa elever avstår från att byta om och duscha efter idrottslektionen.

    - Vad anser eleverna om att duscha och byta om öppet med andra elever?

    - Skiljer sig tjejernas och killarnas erfarenheter av omklädningsrummet åt?

    Metod

    Undersökningen är kvantitativ och jag använde mig av en enkätundersökning som omfattar 60 elever. Deltagarna i min undersökning är elever från en klass i årskurs 7, 8 och 9.

    Resultat

    Resultatet av enkätundersökningen visade att hälften av alla elever inte duschade och många av dem på grund av risken för kränkande behandling, hur ens kropp ser ut och att det är ofräscht i omklädningsrummet. Undersökningen visade också att hälften av eleverna ansåg att det aldrig sker kränkande behandlingar i omklädningsrummet. Studien visade inga stora könsskillnader i omklädningsrummet men antalet flickor som blivit utsatta för kränkande behandling var några fler än pojkarna. Däremot visade undersökningen att antalet flickor som är missnöjda med sitt kroppsutseende är högre än pojkarna. Undersökningen visade även att de elever som var missnöjda med sin kropp också var de som undvek att duscha efter idrottslektionen.

    Slutsats

    Undersökningen visar att många elever är missnöjda med sitt kroppsutseende och detta kan vara en orsak till att hälften av eleverna i undersökningen inte duschar efter lektionen. I denna studie framkommer det även att cirka en tredjedel av eleverna säger sig ha blivit utsatta för kränkande behandlingar. Detta är viktigt att skolan tar denna problematik på allvar då en av deras uppgifter är att motverka kränkande behandling.

    Estimating duration-distance relations in cycle commuting in the general population2018In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 13, no 11, article id e0207573Article in journal (Refereed)
    Abstract [en]

    It is important to estimate the duration-distance relation in cycle commuting in the general  population since this enables analyses of the potential for various public health outcomes. Therefore, the aim is to estimate this relation in the Swedish adult population of 2015. For that purpose, the first step was to establish it for adult male and female cycle commuters in Greater Stockholm, Sweden. Whether or not the slopes of these relations needed to be altered in order to make them representative of the general population was evaluated by comparing the levels of maximal oxygen uptake in samples of commuter cyclists and the population. The measure used was the maximal oxygen uptake divided by both the body weight and a cycle weight of 18.5 kg. The body weights in the population samples were adjusted to mirror relevant levels in 2015. Age adjustments for the duration–distance relations were calculated on the basis of the maximal oxygen uptake in the population samples aged 20–65 years. The duration-distance relations of the cycle commuters were downscaled by about 24–28% to mirror levels in the general population. The empirical formula for the distance (D, km) was based on duration (T, minutes)  x  speed (km/min)  x  a correction factor from cycle commuter to the general population  x  age adjustment (A, years). For the males in the general population the formula was: D = T  x  20.76 km/h  x  0.719  x  (1.676 – 0.0147  x  A). For females, the  formula was: D = T  x  16.14 km/h  x  0.763  x  (1.604 – 0.0129  x  A). These formulas, combined with distributions of route distances between home and work in the population, enable realistic evaluations of the potential for different public health outcomes through cycle commuting.

    Decline in cardiorespiratory fitness in the Swedish working force between 1995 and 2017.2018In: Scandinavian Journal of Medicine and Science in Sports, ISSN 0905-7188, E-ISSN 1600-0838Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Long-term trend analyses of cardiorespiratory fitness (VO2 max) in the general population are limited.

    OBJECTIVES: To describe trends in VO2 max from 1995 to 2017 in the Swedish working force and to study developments across categories of sex, age, education, and geographic regions.

    METHODS: 354.277 participants (44% women, 18-74 years) who participated in a nationwide occupational health service screening between 1995 and 2017 were included. Changes in standardized mean values of absolute (L·min-1 ) and relative (ml·min-1 ·kg-1 ) VO2 max, and the proportion with low (<32) relative VO2 max are reported. VO2 max was estimated using a submaximal cycle test.

    RESULTS: Absolute VO2 max decreased by -6.7% (-0.19 L·min-1 ) in the total population. Relative VO2 max decreased by -10.8% (-4.2 ml·min-1 ·kg-1 ) with approximately one-third explained by a simultaneous increase in body mass. Decreases in absolute fitness were more pronounced in men vs. women (8.7% vs. 5.3%), in younger vs. older (6.5% vs 2.3%), in short (11.4%) vs. long (4.5%) education, and in rural vs. urban regions (6.5% vs 3.5%), all p<0.001. The proportions with low VO2 max increased from 27% to 46% (p<0.001).

    CONCLUSION: Between 1995 and 2017, there was a steady and pronounced decline in mean cardiorespiratory fitness in Swedish adults. Male gender, young age, short education and living in a rural area were predictive of greater reductions. The proportion with low cardiorespiratory fitness almost doubled. Given the strong associations between cardiorespiratory fitness and multiple morbidities and mortality, preventing further decreases is a clear public health priority, especially for vulnerable groups.

    Effects of Proton Pump Inhibitors on the bioactivation of dietary nitrate during submaximal exercise2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Abstract

    Aim: The purpose of the study is to show the influence of Proton Pump Inhibitors (PPI in form of esomeprazole) on the bioactivation of dietary nitrate (sodium-nitrate solution) in submaximal exercise, through affecting the gastric pH.

    Method: Randomized, doubled-blinded, placebo-controlled and crossover study with six subjects (mean ± SD, age 29 ± 5years, height 170 ± 5 centimeters, weight 70 ± 5 Kg, BMI 24,36 ± 1,75 Kg/m2 blood pressure 119/ 77 ± 6 mmHg, 3 male and 3 female). They were tested in two different trials. Every trial consisted of two parts. One part was cycling on 4 different submaximal stages (80W/60RPM, 80W/90RPM, 120W/60RPM, 120W/90RPM) for 5 minutes each, with 90 minutes rest in between. The same protocol was repeated. In the beginning of the resting time a sodium nitrate solution (NaNO3-, 10mg/kg body weight) was ingested. VO2, VCO2, RER, VE, Lactate, Glucose, heart rate and blood pressure were recorded. Venous blood samples were taken. Whether esomeprazole (10mg) or a placebo were taken 24h, 12h and directly before being tested in both trials. Subjects were pleased to have a nitrate poor diet starting when taking the pills. An information sheet was provided.

    Results: No significant differences were found between the post values and the treatment. Tendencies of a higher oxygen consumption when taking esomeprazole (2,62%) in comparison to placebo (0,11%) were observed. Systolic BP decreased by 3,91% with the placebo while it decreased just 2,04% with esomeprazole after intake. Sex-specific differences occurred in the metabolism of esomeprazole and dietary nitrate. RER showed a significant post nitrate difference between the female and male participants with t=.006 and a significance in predietary nitrate intake. VE in female (40,79 ± 7,20 L/min) and (50,03 ± 10,09 L/min) in male were as well significant (t=.017).

    Conclusion: Tendencies of effects of PPI are seen in the post-values of VO2 and BP after intake of dietary nitrate. Gender-differences are shown in RER and VE. More research is needed to see the impact of dietary nitrate on the human body under submaximal load.

    Abstract [sv]

    Psykisk ohälsa är den vanligaste orsaken till sjukskrivning. Fysisk aktivitet kan förebygga många former av ohälsa, men vilka fysiska aktivitetsmönster som gynnar psykisk hälsa och kognitiva förmågor är fortfarande okänt. Denna typ av forskning är komplex och kräver samarbete med många olika aktörer i samhället.

    The significance of mitochondrial respiratory function in regulating oxygen uptake and performance in humans2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The mitochondrion is one of the most fascinating organelles of our cells which has kept and keeps researchers busy in studying its origin, the complex morphology, the numerous functions, the rapid adaptations to a variety of stimuli and its role in health and disease. Exercise challenges cellular homeostasis and skeletal muscle mitochondria greatly adapt to repeated bouts of exercise by increasing mitochondrial respiratory function and content to match energy requirements and to better sustain future perturbations induced by muscle contractions. The oxidative capacity of mitochondria has been shown to exceed the capacity of the cardiorespiratory system to supply oxygen to active muscle at maximal exercise intensity. Despite this, exercise training further increases this overcapacity. Little is known about the role of this excess oxidative capacity of mitochondria in regulating oxygen consumption, the role of oxygen delivery in determining exercise-induced skeletal muscle adaptations, and whether any sex-related differences exist. The assessment of mitochondrial respiratory function in high resolution respirometer is largely used for clinical and scientific purposes. However, the reliability of this method has not been systematically investigated and warrant further investigation.

    With this background, specific measures of reliability associated with repeated determination of maximal mitochondrial oxidative phosphorylation in saponin-permeabilized fibres, comparison of the right and left legs, variability with measurements at different time-points and over time, as well as influence of the local anesthetic and wet weight of the fiber bundle on determined maximal mitochondrial oxidative phosphorylation were investigated in paper I. The importance of having the same technicians in preparing the samples, and that the major source of variation in measuring mitochondrial oxidative capacity is the sample preparation per se were shown. Furthermore, other factors such as the possible difference between left and right limbs, two time points of sample collection, fibres bundle weight, time that elapsed after collection of the biopsy, and the use of an anesthetic have only a minor impact on the standard error of the measurement.

    In paper II the physiological significance of having a mitochondrial oxidative capacity in excess of the capacity of the central circulation to deliver oxygen to the tissue was shown by integrating measures of ex vivo mitochondrial respiratory function with direct in vivo measure of oxygen consumption when performing two-legged cycling and one-legged knee extension exercise while inspiring atmospheric air and oxygen enriched air in the same participants. Excess capacity of mitochondria allows submaximal mitochondrial activation at maximal oxygen delivery, thereby maintaining a high mitochondrial oxygen affinity and a high oxygen extraction peripherally. Considering the widespread and increasing sedentary behavior in a society plagued by diseases often linked to mitochondrial dysfunction, these results suggest the importance of preserving a high muscle oxidative capacity throughout life, which can be of significance in patients with heart, circulatory, and overall metabolic diseases.

    Despite known sex-specific metabolic differences in human skeletal muscle and that animal models have consistently shown females having a superior mitochondrial function compare to males, data in humans are lacking. In paper III the first evidence that women possess higher mitochondrial quality compared to men with equal cardiorespiratory fitness and endurance performance was provided. Mitochondrial oxygen affinity varied with the degree of mitochondrial respiration rate and was lower in women compared to men. These results indicate that the higher mitochondrial quality in women may be an important physiological adaptation that compensates for the lower mitochondrial oxygen affinity allowing a higher oxygen extraction peripherally. Moreover, these results could possibly be linked to the difference in life expectancy, disease occurrence and aging between women and men.

    Lastly, in paper IV it was shown that increasing oxygen delivery and exercise intensity by means of breathing hyperoxia during high-intensity exercise did not enhance cardiorespiratory fitness and exercise-induced skeletal muscle adaptations but still resulted in a small beneficial effect on performance in trained cyclists. This small positive effect on performance can be exploited in elite athletes; however, considering the cost/benefit, the unknown health-related problems, and ethical issues of performing hyperoxic-supplemented endurance training, it is arguable if the use of this strategy to maximize endurance performance is worthwhile.

    Overall, this thesis provides useful information for future research on various factors influencing the error of the measurement when assessing mitochondrial respiratory function. Moreover, this thesis sheds light on novel factors that regulate oxygen consumption during exercise, highlighting the importance of maintaining a good mitochondrial function. This thesis also provides possible directions for future studies on mitochondrial function, metabolism and exercise-induced adaptations.

    Stress Fractures of Pars Interarticularis in Adolescent Athletes a Classification System with MRI and CT Enabling Evaluation of The Healing Process2018In: Journal of Exercise, Sports & Orthopedics, E-ISSN 2374-6904, Vol. 5, no 1Article in journal (Refereed)
    Abstract [en]

    Introduction: The purpose of this study was to evaluate healing frequency in different stages of stress reactions in the Pars Interarticularis (PI) using a classification system with MRI and CT. The intervention was 3-month rest from physical activity, without a brace, with the exception of activities of daily living.

    Materials & Method: Twelve adolescent athletes with different stages of Spondolysis were included in the study. They had pathology in the Pars Interarticularis and were clinically examined with MRI and CT 3-6 weeks after debut of Low Back Pain (LBP) and re-evaluated after 3 months intervention with rest from physical activity.

    Results: A combination of MRI and CT scanning to investigate suspected injuries to Pars Interarticularis in adolescent athletes revealed 6 different stages of Spondolysis that ranged from marrow oedema to pseudoarthrosis. After 3 months of rest from physical activity the early stages of Pars Interarticularis injuries healed significantly better than the later stages with rest from physical activity.

    Conclusion: The combination of MRI and CT revealed 6 stages of stress reactions instead of 4 as in Hollenberg's staging with MRI only. In the 3 earliest stages, of these 6, rest from physical activity for 3 months can heal the stress reaction.

    Tränares utbildningar: En undersökning av fyra specialidrottsförbunds validering av tränares utbildning2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syfte och frågeställningar

    Syftet med denna studie är att undersöka om valda specialidrottsförbund har tagit tillvara den utbildningsbakgrund som huvudtränare på elitnivå besitter.

     

    1. Vad för utbildningar har huvudtränare på elitnivå inom valda specialidrottsförbund?

    2. Anser tränarna att deras övriga utbildningar är relevanta för deras tränarskap?

    3. Har dessa tränare fått sina tidigare utbildningar validerade av specialförbunden?

     

    Metod

    Urvalet bestod av 180 huvudtränare inom fyra specialidrottsförbund: fotboll, innebandy, ishockey och basket. Tillvägagångssättet var enkäter, och då i form av den webbaserade tjänsten Google Forms. Enkäten bestod av 16 frågor, där både öppna och slutna frågor förekom. Resultatet baseras på 61 besvarade enkäter.

     

    Resultat

    Sett till högsta utbildningsnivå så hade 25% av tränarna eftergymnasial utbildning, 36% av tränarna högskole-/universitetsutbildning och 39% av tränarna gymnasieutbildning. 54% av tränarna ansåg att deras övriga utbildning var relevant. Två tränare har kunnat validera tidigare kunskaper.

     

    Slutsats

    Utifrån studien och tidigare forskning så kan man konstatera att specialidrottsförbunden har en välutbildad tränarkår. Majoriteten av tränarna ansåg dessutom att deras övriga utbildning var relevant i förhållande till sitt uppdrag, trots detta var det endast ett fåtal tränare som lyckats ta en annan väg till toppen än genom förbundets utbildningar, vilket tolkas som att det bara finns en väg som leder till elittränarskap och att förbunden inte tar tillvara tränarnas tidigare kunskaper

    Idrottslärarnas inställning till styrketräning för högstadieelever2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning

    Syfte

    Denna studie syftar till att undersöka svenska idrottslärares inställning till styrketräning. Jag undersöker ett antal lärares inställning till styrketräning i idrottsämnet på högstadienivån och konstaterar att alla har en positiv syn men att det finns en viss skepsis mot styrketräning på gym. Det verkar som om nya idrottslärare kan behöva få information om ny forskning som påvisar att även träning på gym har positiva effekter på ungdomar om den utförs rätt.

    Frågeställningar

    • Hur ser lärarna på styrketräning på lektionerna i Idrott och hälsa på högstadiet?

    • Vad anser lärarna angående fördelar och nackdelar med styrketräning?

    • Vad är lärarnas uppfattning om Riksidrottsförbundets rekommendationer när det

       gäller styrketräning för barn?

    • Går det att säga utifrån det som framkommer av intervjuerna att kunskap om

       styrketräningens effekter saknas hos många lärare?

    Metod

    Metoden som används är kvalitativa intervjuer. Urvalet bestod av sex stycken idrottslärare på högstadienivå, fyra män och två kvinnor. Intervjuerna spelades in. Jag ville helst ha lärare med flera års erfarenhet av att undervisa för barn eftersom jag ville ha lärare som hunnit reflektera över hur de ska göra med styrketräningen i skolan och som hunnit stöta på eventuella problem. Sedan handlar det också om att utvärdera resultaten i förhållande till Riksidrottsförbundets rekommendationer och den moderna forskningens syn på styrketräning för barn och ungdomar.

    Resultat

    De flesta idrottslärare är ense om att styrketräning medför mest fördelar för barnen. Både lärarna och forskningen anser att styrketräning förebygger både skador och påskyndar rehabilitering. Lärarna känner delvis till Riksidrottsförbundets rekommendationer men verkar inte ta så stort intryck av dem.

    Slutsats

    Slutsatsen av denna studie är att inställningen i huvudsak är positiv men att det verkar finns en utbredd uppfattning om att gymträning bör undvikas som idrottslärarutbildningen kanske ska utmana.

    "Idrott åt alla" men anläggningar åt vissa: En kvalitativ studie om kommunal idrottspolitik2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Aim: This study aims to explore the reasoning of Swedish municipality councils, in regards to the decision-making process of building new sports facilities, and their relationship to national sports policies. The Swedish sports policy has been specified through a proposition (Prop. 2008/09:126) given by the government and approved by the parliament in 2009 together with the policy program of the Swedish Sports Confederation called Idrotten vill.

    Method: Three Swedish municipalities with sports establishments subsidized by tax money constructed after 2009 were selected for the study. The municipality council’s decisions have been qualitatively studied through Fairclough and Fariclough’s model for political reasoning. The assumption was made that each municipality’s core goal is to maximize their control over political office, in accordance with Strom’s theory of political party behavior.

    Results: The analysis shows that the policies advocated on state level only plays a minor role in the decision-making of municipality councils. Values like the town’s appeal to outsiders, stimulation of the market and the prestige of local sports teams are more dominant in the decision-making process. The reasoning behind all three of the newly built establishments goes in the same direction, which indicates that this might be a trend embraced by several Swedish municipalities.

    Conclusions: Swedish municipality councils reasoning within the decision-making process does not seem to accord with the sports policies advocated on a national level. Previous research has shown indications that personal interests plays a role in municipal decision-making and that the popular belief among both voters and political actors is that the economical benefits of elite sports on the local community is a lot higher than research shows. Both these factors may be explanatory as to why municipal councils chose to disregard national values and policies of sports and the whole advocated concepts of “sports for all” that permeates all of the Swedish sports society.

    The effect of flywheel training on functional neuromuscular performance in physically active youth2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Aim

    The aim of this study was to investigate the effect of flywheel resistance training on functional neuromuscular performance in physically active youth.

     

    Method

    Forty-four healthy and physically active youth between 12-14 years of age (n=19 boys & n=25 girls) volunteered to participate and were randomized into three different groups of flywheel resistance training (FRT) (n=15, body mass = 42,9 ± 8,6 kg, time to Peak Height Velocity (PHV) = - 0,8 ± 1,6), traditional strength training (TST) (n=15, body mass = 44,7 ± 10,3 kg, time to PHV = - 0,8 ± 1,5) and a control group (CON) (n=14, body mass = 43,8 ± 9,0 kg, time to PHV- 0,8 ± 1,5. Squat jump (SQ), Countermovement jump (CMJ), 10-m acceleration, 20-m speed and 30-sprint was assessed pre- and post-intervention. All training groups performed 12 resistance training sessions over a 6-week intervention. The FRT-group performed bilateral flywheel resistance squats with 4 sets of 6 repetitions with 0,025 to 0,05 kgm2 and the TST-group performed bilateral barbell squats with 4 sets of 6 repetitions at a predicted 80 %1RM, while the control group only performed their regular sports training.

     

    Results

    Repeated measures two way-ANOVA, 3 x 2 (training group x time), showed no significant mean effects between groups after the intervention. A significant increase occurred in the control group for SQ; 2,4 ± 2,5 (cm) p ≤ 0,008 and CMJ; 2,2 ± 3,1 (cm) p ≤ 0,037. Both training groups increased significantly in body mass from pre- to post-tests by 2,0 ± 2,7 kg for the flywheel training group and 1,3 ± 0,9 kg in the traditional strength training group (p ≤ 0,05).

     

    Conclusions

    This study indicates that flywheel training can be used as a resistance training method for youth athletes without inducing training related injuries. Flywheel resistance training resulted in a small but non-significant increase from pre to post test in squat jump and 10-m sprint. Future studies on flywheel resistance training for youth needs to investigate the implementation of longer training periods, additional training sessions, more experienced youth in resistance training and faster movement speed.

    En pilotstudie av kognitiv beteendeterapi som metod för beteendeförändring gällande fysisk aktivitet2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sammanfattning

    Syfte

    Syftet med föreliggande studie var att genomföra ett pilottest av delar av forskningsprojektet "Fysisk aktivitet och hjärnhälsa" på Gymnastik- och idrottshögskolan. Pilottestet prövade en manualbaserad metod som grundar sig i kognitiv beteendeterapi, och utvärderade manualen som metod för beteendeförändring av fysisk aktivitet. Frågeställningarna var: Hur genomförbar ansåg samtalsledarna att den manualbaserade metoden med tillhörande verktyg var? Vilka styrkor och svagheter förekom? Hur upplevde deltagarna att deras beteende gällande fysisk aktivitet förändrades med hjälp av samtalsstödet?

    Metod

    Med en kvalitativ utgångspunkt genomfördes totalt 12 individuella samtal med fyra deltagare. Varje samtal utgick från en manualbaserad metod som grundar sig i kognitiv beteendeterapi, med fem tillhörande verktyg. Resultatet av frågeställning ett (1) besvarades genom samtalsledarnas reflektioner kring styrkor och svagheter avseende genomförbarheten av KBT-manualen. Samtalsledarna antecknade sina tankar kring manualens upplägg, såsom förbättringar av verktygen eller utformning av manualen. Frågeställning två besvarades genom innehållsanalys där meningsbärande enheter togs fram genom ett utvärderingsformulär och verktygen Vidmakthållande och Bakslagshantering samt VAS-skalorna.

    Resultat

    Resultatet av studien visade att manualen för kognitiv beteendeterapi med tillhörande verktyg var genomförbar med flertal styrkor men med utrymme för fåtal korrigeringar. Samtalsstödet hjälpte deltagarna att öka sin nivå av fysisk aktivitet.

    Slutsats

    Denna studie har visat att en beteendeförändring i fysisk aktivitet kan uppnås med hjälp av samtalsstöd i form av kognitiv beteendeterapi med tillhörande verktyg. Kognitiv beteendeterapi visade sig i föreliggande studie vara ett hjälpsamt verktyg i en beteendeförändring för fysisk aktivitet, och med hjälp av samtalsstödet skapades nya önskvärda beteendemönster.

    Abstract

    The aim was to explore women’s perceptions of web-based physiotherapy for musculoskeletal pain treatment delivered through an interactive application for smartphones. Questions: To what extent do women have a positive experience of participation, information and availability after web-based physiotherapy through an interactive app? Is there a difference in a-c between women who had visited primary care 2016 (NPE) and the ones who had received physiotherapeutic treatment trough the app (FT-app)?

    Background: The popularity of eHealth is growing both among health care innovators and media. eHealth may increase the access of health services and the evaluation of new services is important. Internet based psychological treatment for musculoskeletal pain is an alternative to traditional treatment in Sweden. A pilot with web-based physiotherapeutic treatment delivered through an interactive app (FT-app) was tested 2014-2017 for treatment in women with musculoskeletal pain. The app included a chat where the physiotherapist answered questions within 24 hours (mon-fri), an activity diary, videos of the exercises and uploaded movies from the patient doing the exercise. The treatment was based on behavioral medicine and lasted for at least 12 weeks. The women were screened for red and yellow flags before start and had no acute pain.

    Method: A web-based survey with 37 questions was emailed to the women (n=139) 1-24 months after finishing the treatment in FT-app. A Likert scale was used for rating the answer 1-4 and 1-5. The results were compared to results from women’s perceptions of primary health care in Sweden 2016 (NPE). The response rate in both samples were analyzed with a z-test.

    Results: 52,5 % answered the survey. The majority answered positively to the claim that getting answer and feedback within 24 hours made compliance to treatment plan easier (92,3%) and helped them accomplish the prescribed exercises and activity (94,5%). The written dialogue was effective for remembering the advices (93,2%) and the FT-app made it possible for the women to adjust the treatment to their everyday living (95,9%). There were significant differences between NPE and FT-app regarding explanation of the treatment (p=0,0045) information of warning signals (p=0,0002) and ways of contact (p=0,0045).

    Conclusion: This study shows that the FT-app women experienced a significant greater participation and access to the service compared to the primary care women in some claims. The response rate was not big enough to generalize the results to the population and the survey was not tested for validity or reliability. This study suggests more research in this field to investigate perceptions of internet-based treatment and to identify when telerehabilitation is suitable as an alternative to traditional health care.
