  • Orthorexia nervosa : An integrative literature review of a lifestyle syndrome
  • 2015
  • Ingår i: International Journal of Qualitative Studies on Health and Well-being. - Järfälla : Taylor & Francis. - 1748-2623 .- 1748-2631. ; 10:1
  • Forskningsöversikt (refereegranskat)abstract
    • Bratman first proposed orthorexia nervosa in the late 1990s, defining it an obsession with eating healthy food to achieve, for instance, improved health. Today, in the Swedish media, excessive exercising plays a central role in relation to orthorexia. A few review articles on orthorexia have been conducted; however, these have not focused on aspects of food and eating, sport, exercise, or a societal perspective. The overall aim of this study was to provide an overview and synthesis of what philosophies of science approaches form the current academic framework of orthorexia. Key questions were: What aspects of food and eating are related to orthorexia? What role do exercise and sports play in relation to orthorexia? In what ways are orthorexia contextualized? Consequently, the concept of healthism was used to discuss and contextualize orthorexia. The method used was an integrative literature review; the material covered 19 empirical and theoretical articles published in peer-reviewed journals. This review demonstrates a multifaceted nature of orthorexia research; this field has been examined from four different philosophies of science approaches (i.e., empirical-atomistic, empirical-atomistic with elements of empirical-holistic, empirical-holistic, and rational-holistic) on individual, social, and societal levels. The majority of the articles followed an empirical-atomistic approach that focused on orthorexia as an individual issue, which was discussed using healthism. Our analysis indicates a need for (a) more empirical-holistic research that applies interpretive qualitative methods and uses a social perspective of health, e.g., healthism and (b) examining the role of sports and exercise in relation to orthorexia that takes the problematizing of "orthorexic behaviours" within the sports context into account.

  • Gender Differences and Inequality? A 20-Year Retrospective Analysis Based on 39,980 Students' Perceptions of Physical Education in Sweden
  • 2023
  • Ingår i: Journal of Teaching in Physical Education. - : Human Kinetics. - 0273-5024 .- 1543-2769. ; 42:2, s. 371-382
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: The aim of this study was to critically examine previous studies' claims about the magnitude of gender differences and gender inequality in physical education (PE) in Sweden. Method: The data were based on students' (N = 39,980) perceptions of PE and were gathered from four large research projects in Sweden. Three effect size measures (Cramer's V, r squared, and Cohen's d) were calculated for gender differences. Results: In general, there are small gender differences; and after controlling for students' grade, "sports capital," and parents' "educational capital," the differences are practically irrelevant. Conclusion: This study provides compelling evidence that there are small, or even irrelevant, gender differences in students' perceptions of PE in Sweden. Moreover, given that previous research asserts that large gender differences can be used as an indicator of inequality, this study suggests that gender inequality issues related to students' perceptions of PE are relatively small.

  • 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.

  • The role of greenery for physical activity play at school grounds
  • 2014
  • Ingår i: Urban Forestry & Urban Greening. - : Elsevier BV. - 1618-8667 .- 1610-8167. ; 13:1, s. 103-113
  • Tidskriftsartikel (refereegranskat)abstract
    • Greenery is assumed to promote physical activity at school grounds by facilitating open and flexible play situations that engage many children. The role of greenery for school ground activity was investigated at two schools, one of which contained a substantial amount of greenery and the other one little greenery. All in all 197 children from 4th (10-11 years) and 6th grade (12-13 years), were involved in a one week field study, documenting self-reported school ground use, their favourite places and favourite activities and counting their steps by pedometer. The most common school ground activities were related to the use of balls as part of different sports, games and other playful activity. The more extensive green areas belonged to children's favourite places, but were little used, whereas settings with a mix of green and built elements in proximity to buildings were well-used favourites. Physical activity in steps was similar at the two schools, but on average girls got less of the activity they need during recess. Greenery was found important by contributing to settings attractive to visit for girls as well as boys and for younger as well as older children, if located in ways that also supported peer interaction and various games.

  • 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.

  • Electronic sport and its impact on future sport
  • 2010
  • Ingår i: Sport in Society. - Abingdon : Informa UK Limited. - 1743-0437 .- 1743-0445. ; 13:2, s. 287-299
  • Tidskriftsartikel (refereegranskat)abstract
    • According to public health and media discourses, the mere mentioning of computer gaming (E-sport) as a form of sports might be considered subversive. As a matter of fact, the two practices are considered to be oppositional. Sports are often regarded as virtuous, whereas computer gaming is looked upon as a vice. In this light, the basic aim of this essay is to discuss and analyse the ‘sporting qualities’ of competitive computer gaming in relation to the definition of sport. The reasoning will also forecast the future of competitive computer gaming. How might this new form of ‘sport’ develop and what impact will it have on future sports in general? We answer the question by presenting three possible scenarios. Might it even be that we are standing on the threshold of a new phase in the evolution of sports?

  • The social construction of ability in movement assessment tools
  • 2017
  • Ingår i: Sport Education and Society. - : Informa UK Limited. - 1357-3322 .- 1470-1243. ; 22:6, s. 697-709
  • Tidskriftsartikel (refereegranskat)abstract
    • This paper focuses on how ability' is conceptualised, configured and produced in movement assessment tools. The aim of the study was to critically analyse assessment tools used for healthy and typically developed children. The sample consists of 10 tools from 6 different countries. In the study, we pay special attention to content and evaluation methods. The theoretical analysis explores and discusses what kind of movement ability the tools construct. The theoretical framework is inspired by Bourdieu's concepts of habitus, capital and field which are used as analytical tools to explore how the testing processes and content shape what is regarded as ability. Our findings show both a great variation of concepts and evaluation methods and a narrow view of what is regarded as valuable to assess. The assessed movements are strongly related to traditional sports and construct a specific form of physical capital. None of the tasks assessed take place in natural outdoor environments. Open skills, rhythmical movements to music or tasks including a wider range of flexibility are also absent in the assessment tools. The explored tools and tests assess a limited number of decontextualised movements and produce a narrow view of ability'. Hence, the testing process itself often promotes a child who is physically mature and benefits those who have experience of traditional sports. In other words, the assessed taste for sport' and the embodied physical capital' construct what is considered to be legitimate knowledge in relation to movement and physical culture. Accordingly, the social construction of movement ability through assessment tools is far from a neutral concept and could affect how children see themselves and their ability'.

  • Stress Fractures of Pars Interarticularis in Adolescent Athletes a Classification System with MRI and CT Enabling Evaluation of The Healing Process
  • 2018
  • Ingår i: Journal of Exercise, Sports & Orthopedics. - : Symbiosis Group. - 2374-6904. ; 5:1
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.

  • Does behaviour match user typologies? An exploratory cluster analysis of behavioural data from a gamified fitness platform.
  • 2022
  • Ingår i: CEUR Workshop Proceedings. - RWTH Aachen : CEUR Workshop. - 1613-0073. ; , s. 105-114
  • Konferensbidrag (refereegranskat)abstract
    • A promising solution to increase user engagement in gamified applications is tailored gamification design. However, current personalisation relies primarily on user types identified through self-reporting rather than actual behaviour. As a novel approach, the present study used an exploratory machine learning analysis to identify seven clusters of users in a gamified fitness application based on their behavioural data (N = 19,576). The clusters were then conceptually compared to common user typologies in gamification, identifying possible relationships between behavioural user clusters and user types motivated by achievement, sociability, and extrinsic incentives. The findings shed light on nuanced behaviour patterns of user types in the fitness context and how knowing these patterns can inform the way in which tailored gamification could be implemented to meet the needs of specific types. Thereby, they contribute to the discussion on utilising behavioural data and user typologies for tailored gamification design.

  • Moving from Knowledge to Action: A Qualitative Study of Elite Coaches’ Capacity for Early Intervention in Cases of Eating Disorders
  • 2013
  • Ingår i: International Journal of Sports Science & Coaching. - : SAGE Publications. - 1747-9541 .- 2048-397X. ; 8:2, s. 343-355
  • Tidskriftsartikel (refereegranskat)abstract
    • This study investigates elite coaches’ attitudes toward eating disorders (ED), knowledge about ED, and early intervention skills when confronted with possible ED in their female athletes. We interviewed 18 coaches in Sweden responsible for athletes representing national teams in the three sports categories most at risk for ED: aesthetic, weight class, and endurance. The interviews revealed that, although most coaches knew athletes with ED, they did not perceive ED as a problem in their sport. The majority of coaches cited difficulties in identifying ED symptoms, especially symptoms associated with bulimia nervosa. Coaches also described several barriers in approaching the athletes, including the athletes’ denial of ED, lack of female colleagues on the team and the lack of easily accessible resources for treatment referral on both the national sports federation and the club levels. This study reveals that elite coaches have insufficient capacity to identify ED and conduct early intervention, resulting in delayed treatment.

  • Rehabilitation after first-time anterior cruciate ligament injury and reconstruction in female football players: a study of resilience factors
  • 2016
  • Ingår i: Bmc Sports Science Medicine and Rehabilitation. - London : Springer Science and Business Media LLC. - 2052-1847. ; 8
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Most of the research in the area of psychosocial factors in rehabilitation after sports injuries has focused on risk behaviors, while relatively few studies have focused on behaviors that facilitate rehabilitation. The objective of our study was to understand the psychosocial features that characterize elite female football players who express a resilient behaviour during rehabilitation after a first-time anterior cruciate ligament (ACL) injury and reconstruction. Methods: A qualitative method was used based on individual in-person interviews and video communication of players who incurred a first-time ACL tear during the 2012 season of the Swedish Women's Elite Football League. In total, 13 players had a first-time ACL and were interviewed post-season. The interviews were followed by a thematic content analysis. Based on this, eight players were identified as showing resilient behaviors during their rehabilitation and were included in the final analysis. Results: Three core themes representing psychosocial factors that help players cope successfully with rehabilitation were identified: (I) constructive communication and rich interaction with significant others; (II) strong belief in the importance and efficacy of one's own actions; and (III) the ability to set reasonable goals. Conclusions: The findings suggest three core themes of psychosocial factors that characterize first-time ACL-injured elite female football players showing resilience during rehabilitation after ACL reconstruction. Suggestions for medical teams about ways to support communication, self-efficacy, and goal-setting during the rehabilitation process, are provided.

  • Empowering aspects for healthy food and physical activity habits : adolescents’ experiences of a school-based intervention in a disadvantaged urban community
  • 2018
  • Ingår i: International Journal of Qualitative Studies on Health and Well-being. - Abingdon : Taylor & Francis. - 1748-2623 .- 1748-2631. ; 13:sup1: Equal Health
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose:This study aimed to describe adolescents’ experiences of participating in a health-promoting school-based intervention regarding food and physical activity, with a focus on empowering aspects. Method:The school was located in a urban disadvantaged community in Sweden, characterized by poorer self-reported health and lower life expectancy than the municipality average. Focus group interviews with adolescents (29 girls, 20 boys, 14–15 years) and their teachers (n = 4) were conducted two years after intervention. Data were categorized using qualitative content analysis. Results: A theme was generated, intersecting with all the categories: Gaining control over one’s health: deciding, trying, and practicing together, in new ways, using reflective tools. The adolescents appreciated influencing the components of the intervention and collaborating with peers in active learning activities such as practicing sports and preparing meals. They also reported acquiring new health information, that trying new activities was inspiring, and the use of pedometers and photo-food diaries helped them reflect on their health behaviours. The adolescents’ experiences were also echoed by their teachers. Conclusions: To facilitate empowerment and stimulate learning, health-promotion interventions targeting adolescents could enable active learning activities in groups, by using visualizing tools to facilitate self-reflection, and allowing adolescents to influence intervention activities.

  • Effects of a 10-Week Physical Activity Intervention on Asylum Seekers' Physiological Health
  • 2022
  • Ingår i: Brain Sciences. - : MDPI. - 2076-3425. ; 12:7
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: The rise in armed conflicts has contributed to an increase in the number of asylum seekers. Prolonged asylum processes may negatively affect asylum seekers' health and lead to inactivity. Studies show that physical activity interventions are associated with improvements in health outcomes. However, there are a limited number of studies investigating the associations of physical activity on asylum seekers' health. Methods: Participants (263 males and 204 females), mostly from Syria, were assessed before and after a 10-week intervention for VO2 max, body mass index (BMI), skeletal muscle mass (SMM), body fat, and visceral fat. Linear mixed models were used to test differences within groups, and a linear regression model analysis was performed to test whether physiological variables predicted adherence. Results: Participants' VO2 max increased: males by 2.96 mL/min/kg and females 2.57 mL/min/kg. Increased SMM percentages were seen in both genders: females by 0.38% and males 0.23%. Visceral fat area decreased: males by 0.73 cm(2) and females 5.44 cm(2). Conclusions: Participants showed significant increases in VO2 max and SMM and decreased visceral fat. This study provides an insight into asylum seekers' health and serves as a starting point to new interventions in which physical activity is used as a tool to promote and improve vulnerable populations' health.

  • 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.

  • Psychological Distress and Problem Gambling in Elite Athletes during COVID-19 Restrictions : A Web Survey in Top Leagues of Three Sports during the Pandemic.
  • 2020
  • Ingår i: International Journal of Environmental Research and Public Health. - : MDPI. - 1661-7827 .- 1660-4601. ; 17:18
  • Tidskriftsartikel (refereegranskat)abstract
    • COVID-19 and lockdown strategies may affect mental health and addictive behavior differently in the population, and elite athletes are among the professions clearly affected by the pandemic. This study in top elite athletes aimed to study current perceived psychological influence from COVID-19 and symptoms of depression, anxiety and changes in alcohol drinking, gambling behavior and problem gambling in the midst of the COVID-19 lockdown. This web survey included athletes in top leagues of soccer, ice hockey and handball in Sweden (N = 327, 62% men). A total of 66% and 51% were worried about the future of their sport or about their own future in sports, respectively. Feeling worse psychologically during the pandemic was common (72% of women, 40% of men, p < 0.001); depression criteria were endorsed by 19% of women and three percent of men (p < 0.001); anxiety criteria by 20% of women and five percent of men (p < 0.001). Reporting increased gambling during the pandemic was associated with gambling problem severity. Moderate-risk or problem gambling was seen in 10% of men and none of the women (p < 0.001). Depression and anxiety were associated with feeling worse during the COVID-19 pandemic and with concern over one's own sports future. In conclusion, COVID-19-related distress is common in elite athletes and associated with mental health symptoms. Gambling increase during the pandemic was rare, but related to gambling problems, which were common in male athletes. The calls for increased focus on COVID-19-related concerns in athletes and on problem gambling in male athletes.

  • Re-examination of accelerometer data processing and calibration for the assessment of physical activity intensity.
  • 2019
  • Ingår i: Scandinavian Journal of Medicine and Science in Sports. - : John Wiley & Sons. - 0905-7188 .- 1600-0838. ; 29:10, s. 1442-1452
  • Tidskriftsartikel (refereegranskat)abstract
    • This review reexamines use of accelerometer and oxygen uptake data for assessment of activity intensity. Accelerometers capture mechanical work, while oxygen uptake captures the energy cost of this work. Frequency filtering needs to be considered when processing acceleration data. A too restrictive filter attenuates the acceleration signal for walking and, to a higher degree, for running. This measurement error affects shorter (children) more than taller (adults) individuals due to their higher movement frequency. Less restrictive filtering includes more movement related signals and provide measures that better capture mechanical work, but may include more noise. An optimal filter cut-point is determined where most relevant acceleration signals are included. Further, accelerometer placement affects what part of mechanical work being captured. While the waist placement captures total mechanical work and therefore contributes to measures of activity intensity equivalent by age and stature, the thigh and wrist placements capture more internal work and do not provide equivalent measures. Value calibration of accelerometer measures is usually performed using measured oxygen uptake with the metabolic equivalent of task (MET) as reference measure of activity intensity. However, the use of MET is not stringent and is not a measure of activity intensity equivalent by age and stature. A candidate measure is the mass-specific net oxygen uptake, VO2 net (VO2 tot - VO2 stand). To improve measurement of physical activity intensity using accelerometers, research developments are suggested concerning processing of accelerometer data, use of energy expenditure as reference for activity intensity, and calibration procedure with absolute versus relative intensity.

  • Being a Group Fitness Instructor during the COVID-19 Crisis : Navigating Professional Identity, Social Distancing, and Community
  • 2021
  • Ingår i: Social Sciences. - : MDPI. - 2076-0760. ; 10:4
  • Tidskriftsartikel (refereegranskat)abstract
    • Research question and purpose: Les Mills is a New Zealand-based fitness distributor with a community consisting of approximately 140.000 instructors worldwide who teach standardized workout routines. This paper aims to explore how the COVID-19 pandemic and related measurements, such as social distancing affect the everyday lives and professions of Les Mills International (LMI) group fitness instructors. The aim was met with the following research questions: RQ1: How are social distancing and social connectedness understood, and how do they condition LMI instructors' understanding of their profession? RQ2: What do LMI instructors think about the #LesMillsUnited campaign to maintain a strong trainer community in the midst of the pandemic? RQ3: How do LMI instructors think that group fitness will change long term due to social distancing? Research methods: Using qualitative measures and a case-study-based approach, data were gathered through interviews with LMI-certified group fitness instructors. Seven semi-structured focused group discussions with fifteen group fitness instructors from different countries were conducted and audio recorded. The first round of virtual discussions took place in April 2020, and the follow-up talks in September 2020. A thematic analysis was employed to analyze the material. Results and findings: According to the participants, online classes as a means of upholding group fitness in times of social distancing is an insufficient substitute to face-to-face instructing, lacking social connectedness that is normally maintained through successful rituals or social scripts. Navigating "instructorhood" during the pandemic includes emotional labor where not only relationships to clients are challenged, but instructors also experience societal pressure to reinvent themselves as instructors. Implications: With no way of telling how long social distancing needs to be practiced, the group fitness industry is facing unprecedented challenges. Making sense of the group fitness profession currently preoccupies instructors who may now have to redefine to themselves how they can teach, and who for.

  • Musculoskeletal pain and its association with health status, maturity, and sports performance in adolescent sport school students: a 2-year follow-up
  • 2022
  • Ingår i: Bmc Sports Science Medicine and Rehabilitation. - London : Springer Science and Business Media LLC. - 2052-1847. ; 14:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Background Musculoskeletal pain and its risk factors are rarely assessed in studies on adolescent athletes. The aim was to identify risk factors at baseline that were associated with the persistence or development of musculoskeletal pain at a two-year follow-up in adolescent sport school students, and to study cross-sectional associations at follow-up between musculoskeletal pain and sports performance. Methods Sport school students (79 boys and 52 girls, aged 14 years at baseline) were divided into infrequent (never-monthly) or frequent (weekly-almost daily) pain groups, based on frequency of pain using a pain mannequin. Logistic regression analyses were performed to study longitudinal associations between frequent pain at follow-up and baseline variables: pain group, number of regions with frequent pain, health status by EQ-5D, maturity offset (pre, average, or post peak height velocity), and sports (contact or non-contact). Linear regression analyses were used to study cross-sectional associations between pain groups and 20-m sprint, agility T-test, counter-movement jump, and grip strength at follow-up. Results were stratified by sex. Results A higher percentage of girls than boys reported frequent pain at follow-up (62% vs. 37%; p = 0.005). In boys, frequent pain at follow-up was associated with being pre peak height velocity at baseline (OR 3.884, CI 1.146-13.171; p = 0.029) and participating in non-contact sports (OR 3.429, CI 1.001-11.748; p = 0.050). In girls, frequent pain at follow-up was associated with having frequent pain in two or more body regions at baseline (OR 3.600, CI 1.033-12.542; p = 0.044), having a worse health status at baseline (OR 3.571, CI 1.026-12.434; p = 0.045), and participating in non-contact sports (OR 8.282, CI 2.011-34.116; p = 0.003). In boys, frequent pain was associated with worse performances in 20-m sprint and counter-movement jump, but not in agility T-test and grip strength. Conclusions Baseline risk factors for having frequent pain at follow-up were late maturation in boys, frequent pain and worse health status in girls, and participation in non-contact sports in both sexes. Boys with pain performed worse in sports tests. Coaches and school health-care services should pay attention to the risk factors and work towards preventing pain from becoming persistent.

  • Effects of a 10-Week Physical Activity Program on Asylum Seekers’ Physiological Health
  • 2020
  • Ingår i: 32nd Association for Psychological Science Annual Convention. Chicago, Illinois, USA.
  • Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
    • We evaluated the effect of a 10-week training program on physiological health among a sample of 465 asylum seekers in Sweden, most of them from Syria. We found increases on the overall maximum aerobic fitness along with body composition (e.g., skeletal muscle mass) and a decrease in body fat.

  • Vigorous Physical Activity may be Important for the Insulin Sensitivity in Immigrants From the Middle East and Native Swedes
  • 2015
  • Ingår i: Journal of Physical Activity & Health. - : Human Kinetics. - 1543-3080 .- 1543-5474. ; 12:2, s. 273-281
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: To compare physical activity measures and their associations with insulin sensitivity, beta-cell function and body mass index (BMI) between Iraqi immigrants and native Swedes. Methods: A cross-sectional study of 493 Iraqis (58% men) and 469 Swedes (54% men) aged 30 to 75 years living in the city of Malmo, Sweden. Accelerometry was used for physical activity measures (sedentary time, breaks in sedentary time, moderate and vigorous physical activity, total counts). Insulin sensitivity index and oral disposal index were determined from an oral glucose tolerance test and BMI by body weight and height. Results: Iraqi men were less physically active than Swedish men, while the physical activity was more similar in the women. BMI was a strong predictor of insulin sensitivity and beta-cell function and frequently associated with the physical activity measures. BMI modified the associations of insulin sensitivity and beta-cell function with the physical activity measures to such extent that only VPA and total counts show direct associations with insulin sensitivity in addition to the indirect associations via BMI. Iraqi women demonstrated weaker associations compared with Swedish women. Conclusions: Physical activity and performed at vigorous intensity may be important mainly for the insulin sensitivity in Iraqi immigrants and native Swedes.
