  • Supportive Communities: Conceptualizing Supportive Structures for Coaches' Learning and Well-Being in Community Youth Soccer
  • 2022
  • Ingår i: International Journal of Environmental Research and Public Health. - Basel : MDPI AG. - 1660-4601 .- 1661-7827. ; 19:14
  • Tidskriftsartikel (refereegranskat)abstract
    • Sweden has an extensive culture of community club sports for children and youths, based on voluntary leadership. Being a voluntary coach can be stressful and can affect coaches' well-being. Since voluntary coaching is closely connected to and conditioned by family life and civil occupation, coaches need support for practical issues as well as for developing their coaching assignment in relation to the constantly changing conditions within sports for children and youths. The aim of this paper was to conceptualize and problematize the supportive structures in everyday activities, in order to promote learning and well-being and to prevent mental health issues. This paper is conceptual and based on a paradigm case. The starting point is communities of practice (CoP) and how CoPs can contribute to the development of supportive structures for coaches in youth sports. In conclusion, a CoP is dependent on negotiation within the coaching team as well as on facilitating factors that can add knowledge, perspectives, and experiences to the CoP. The facilitating factors mean that a CoP has the potential to be health-promoting for both coaches and players. Hence, it is important to create conditions, structures, and support-such as policies, practice-based education, mentorship, and facilitators.

  • Is Physiological Equivalent Temperature (PET) a superior screening tool for heat stress risk than Wet-Bulb Globe Temperature (WBGT) index? : Eight years of data from the Gothenburg half marathon
  • 2021
  • Ingår i: British Journal of Sports Medicine. - : BMJ Publishing Group Ltd. - 0306-3674 .- 1473-0480. ; 55:15, s. 825-830
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The Wet-Bulb Globe Temperature (WBGT) index is a common tool to screen for heat stress for sporting events. However, the index has a number of limitations. Rational indices, such as the physiological equivalent temperature (PET) and Universal Thermal Climate Index (UTCI), are potential alternatives. Aim: To identify the thermal index that best predicts ambulance-required assistances and collapses during a city half marathon. Methods: Eight years (2010-2017) of meteorological and ambulance transport data, including medical records, from Gothenburg's half-marathon were used to analyse associations between WBGT, PET and UTCI and the rates of ambulance-required assistances and collapses. All associations were evaluated by Monte-Carlo simulations and leave-one-out-cross-validation. Results: The PET index showed the strongest correlation with both the rate of ambulance-required assistances (R2=0.72, p=0.008) and collapses (R2=0.71, p=0.008), followed by the UTCI (R2=0.64, p=0.017; R2=0.64, p=0.017) whereas the WBGT index showed substantially poorer correlations (R2=0.56, p=0.031; R2=0.56, p=0.033). PET stages of stress, match the rates of collapses better that the WBGT flag colour warning. Compared with the PET, the WBGT underestimates heat stress, especially at high radiant heat load. The rate of collapses increases with increasing heat stress; large increase from the day before the race seems to have an impact of the rate of collapses. Conclusion: We contend that the PET is a better predictor of collapses during a half marathon than the WBGT. We call for further investigation of PET as a screening tool alongside WBGT.

  • Effects of a 16-Week Digital Intervention on Sports Nutrition Knowledge and Behavior in Female Endurance Athletes with Risk of Relative Energy Deficiency in Sport (REDs)
  • 2023
  • Ingår i: Nutrients. - Basel : MDPI. - 2072-6643. ; 15:5
  • Tidskriftsartikel (refereegranskat)abstract
    • Female endurance athletes are considered a high-risk group for developing Relative Energy Deficiency in Sport (REDs). Due to the lack of educational and behavioral intervention studies, targeting and evaluating the effects of the practical daily management of REDs, we developed the Food and nUtrition for Endurance athletes—a Learning (FUEL) program, consisting of 16 weekly online lectures and individual athlete-centered nutrition counseling every other week. We recruited female endurance athletes from Norway (n = 60), Sweden (n = 84), Ireland (n = 17), and Germany (n = 47). Fifty athletes with symptoms of REDs and with low risk of eating disorders, with no use of hormonal contraceptives and no chronic diseases, were allocated to either the FUEL intervention (n = 32) (FUEL) or a 16-week control period (n = 18) (CON). All but one completed FUEL, while 15 completed CON. We found strong evidence for improvements in sports nutrition knowledge, assessed via interviews, and moderate to strong evidence in the ratings concerning self-perceived sports nutrition knowledge in FUEL versus CON. Analyses of the seven-day prospective weighed food record and questions related to sports nutrition habits, suggested weak evidence for improvements in FUEL versus CON. The FUEL intervention improved sports nutrition knowledge and suggested weak evidence for improved sports nutrition behavior in female endurance athletes with symptoms of REDs.

  • From giving orders to engaging in dialogue : Military norms being challenged at the Swedish riding school
  • 2018
  • Ingår i: International Review for the Sociology of Sport. - London, UK : Sage Publications. - 1012-6902 .- 1461-7218. ; 53:4, s. 451-470

    • Equestrian sport is one of the largest sports among young girls in Sweden. A majority of these girls get their riding education at riding schools that provide horses and instructors. Previous research has pointed out that the Swedish riding school is characterised by a traditional stable culture that originated in army practices. Presently Swedish children and youth sport at large are undergoing a change driven by increased commercialisation and individualisation. The aim of this article is therefore to explore and analyse how Swedish riding instructors perceive and experience their professional role in regards to these changes. Interviews with 10 riding instructors have been analysed using a constructivist approach of Grounded theory, as well as institutional theory and institutional economic theory. It was discovered that the riding instructors, due to an economic recession, feel that the institutional arrangements of the riding schools have become governed by the economy. The riding instructors thus feel impelled to change and adapt to new teaching styles - from instruction characterised by giving orders to teaching characterised by dialogue. This study illustrates how economic challenges require continuous development of the riding instructors' pedagogical ability, and have made them more aware of their profession, its historical heritage and norms.

  • Mindful Recovery : A Case Study of a Burned-Out Elite Shooter
  • 2013
  • Ingår i: The Sport psychologist. - : Human Kinetics. - 0888-4781 .- 1543-2793. ; 27:1, s. 92-102
  • Tidskriftsartikel (refereegranskat)abstract
    • Research on how to recover from athlete burnout is scarce. The current aim is therefore to describe an intervention with an elite shooter suffering from burnout, and the use of mindfulness and Qigong to reestablish sport functioning as well as general well-being. The participant used mindfulness and Qigong exercise on a daily basis. Exercise frequency, exercise time, concentration level and Qigong state were noted daily, and levels of stress, energy and primordial force were self-rated weekly for 20 weeks, and followed up after 30, 40 and 50 weeks. The participant recovered from burnout to a state of general well-being (energy and primordial force changed from weak to strong), and her ability to stay concentrated in a Qigong state changed from weak to strong. Her capacity to shoot high scores was reestablished, even if her shooting endurance was not fully recovered. Mindfulness and Qigong techniques may be useful in the prevention of and recovery from athlete burnout.

  • Sexual harassment and abuse in coach–athlete relationships in Sweden
  • 2017
  • Ingår i: European Journal for Sport and Society. - : Informa UK Limited. - 1613-8171 .- 2380-5919. ; 14:2, s. 117-137
  • Tidskriftsartikel (refereegranskat)abstract
    • Sexual harassment and abuse (SHA) can have a profound negative impact, but research on SHA in sport is scarce and studies of SHA in Swedish sport are absent. This study explores (a) self-reported prevalence of SHA perpetrated by coaches among male and female Swedish athletes, and (b) descriptive statistics for coach–athlete relationship factors and the association between these relationship factors and reported SHA. Current and former Swedish club sport athletes (n = 477) aged 25 participated in the survey. Athletes reported 5.5% prevalence of coach SHA, of which inappropriate, unpleasant, or offensive physical contact were most common. No significant differences of SHA frequency were displayed across gender, sport performance levels, or individual/team sports. A majority of athletes (55–95%) reported trust, closeness, substantial coach influence over sport performance, and instructional physical contact as main coach–athlete relationship factors. A minority (13–39%) reported dependency, substantial coach influence over personal-life, non-instructional physical contact, sexualized comments and jokes, and flirting. Prevalence of coach–athlete friendships, athlete attraction to coaches, and coaches’ instructional physical contact differed significantly between male and female athletes. Closeness and athlete attraction to coaches were negatively related, and coaches’ non-instructional physical contact and flirting were positively related to reported SHA. Multi-causality and ambiguity of coach–athlete relationship factors are discussed.

  • Motivational profiles and burnout in elite athletes: A person-centered approach
  • 2018
  • Ingår i: Psychology of Sport And Exercise. - : Elsevier BV. - 1469-0292 .- 1878-5476. ; 35, s. 118-125
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim of this study was to assess the link between elite athletes' motivational profiles and burnout using a person-centered approach. Participants were 391 Spanish elite athletes (201 males and 190 females), aged 16-30 years who completed questionnaires measuring demographic information, self-determined motivation, and athlete burnout. Latent profile analysis resulted in a five profile solution labeled: amotivation (Class 1), low motivation (Class 2), moderately autonomous motivation (Class 3), amotivated and moderately controlled motivation (Class 4), and highly motivated (Class 5). While no significant differences were found in emotional/physical exhaustion, Class 4 (amotivated and moderately controlled motivation) scored higher than classes 2 (low motivation), 3 (moderately autonomous motivation), and 5 (highly motivated) on a Reduced sense of Accomplishment and Sport Devaluation. Findings are discussed in relation to Self-Determination Theory, suggesting that the quality of one's motivation may be equally, if not more important than the quantity of motivation in determining subsequent health, well-being, and performance outcomes.

  • Medical Emergencies During a Half Marathon Race - The Influence of Weather
  • 2019
  • Ingår i: International Journal of Sports Medicine. - Stuttgart : Georg Thieme Verlag KG. - 0172-4622 .- 1439-3964. ; 40:5, s. 312-316
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim was to analyze the influence of weather conditions on medical emergencies in a half-marathon, specifically by evaluating its relation to the number of non-finishers, ambulance-required assistances, and collapses in need of ambulance as well as looking at the location of such emergencies on the race course. Seven years of data from the world's largest half marathon were used. Meteorological data were obtained from a nearby weather station, and the Physiological Equivalent Temperature (PET) index was used as a measure of general weather conditions. Of the 315,919 race starters, 104 runners out of the 140 ambulance-required assistances needed ambulance services due to collapses. Maximum air temperature and PET significantly co-variated with ambulance-required assistances, collapses, and non-finishers (R (2) =0.65-0.92; p=0.001-0.03). When air temperatures vary between 15-29 degrees C, an increase of 1 degrees C results in an increase of 2.5 (0.008/1000) ambulance-required assistances, 2.5 (0.008/1000) collapses (needing ambulance services), and 107 (0.34/1000) non-finishers. The results also indicate that when the daily maximum PET varies between 18-35 degrees C, an increase of 1 degrees C PET results in an increase of 1.8 collapses (0.006/1000) needing ambulance services and 66 non-finishers (0.21/1000).

  • The prevalence of emotional exhaustion in professional and semiprofessional coaches
  • 2023
  • Ingår i: Journal of Clinical Sport Psychology. - : Human Kinetics. - 1932-9261 .- 1932-927X. ; 17:4, s. 376-389
  • Tidskriftsartikel (refereegranskat)abstract
    • The present study examined levels of emotional exhaustion, a key symptom of burnout, in Swedish professional and semiprofessional sport coaches in comparison to the normative values specified in the Maslach Burnout Inventory manual, and to the clinical cutoffs developed by Kleijweg, Verbraak, and Van Dijk. The sample contained 318 Swedish coaches (Mage = 42.7 years, 12% female) working at least 50% full time away from both team (60%) and individual (40%) sports. Our study shows that, in general, coaches in this sample experience lower average levels of exhaustion than normative samples both regarding the Maslach Burnout Inventory and clinical cutoffs. Two groups of coaches did, however, stand out. Coaches living in single households as well as coaches working part time had higher risk of severe levels of emotional exhaustion. These results place coach exhaustion levels in relation to other occupations and highlight that in this sample, the coaching profession does not stand out as more emotionally exhausting than other occupations.
