- Background Previous research demonstrates an injury risk of traumatic and overuse injuries in floor-ball which is one of the major sports in Sweden with 1 24 000 licensed players. One important step to prevent overuse injuries to occur is to understand its psychosocial nature. Objective The aim of this study is to describe and structure athletes' experience of psychosocial risk factors preceding overuse injury. Design Elite floor-ball players were interviewed by the first author and based on a semi-structured interview guide. To uncover the underlying meaning in the transcribed interviews, a thematic content analysis was used. Setting Team doctors and physiotherapists in the highest floor-ball leagues (women and men), were contacted and asked to make contact with overuse injured players for interviews regarding their injury. Interviews were recorded at the interviewer's office or the floor-ball arena. The interviews were transcribed verbatim. Participants were informed about the purpose and the method of the study. That participation was voluntary, that their responses would be treated confidentially and that their identities would not be revealed in the reporting of the findings. Participants Nine male and one female elite floor-ball players diagnosed with a present overuse injury were recruited for voluntary participation. Main outcome measurements Psychosocial factors experienced by elite floor-ball players preceding overuse injuries. Assessment of risk factors Assessment is conducted through qualitative analysis. Results Three main themes evolved in the analysis; a) several players experienced pain while competing. However, it is difficult to separate normal/daily pain to warnings signals of an injury, b) many players experienced a culture in the team including not talking about their first symptoms, and, c) time for mental and physical recovery was not given during the season. Conclusion Players experienced a culture where it is not acceptable to talk about non traumatic pain. Periods of rest were limited leading to a need for mental recovery.

Journal article (peer-reviewed)abstract
- In October 2017, the International Olympic Committee hosted an international expert group of physiotherapists and orthopaedic surgeons who specialise in treating and researching paediatric ACL injuries. Representatives from the American Orthopaedic Society for Sports Medicine, European Paediatric Orthopaedic Society, European Society for Sports Traumatology, Knee Surgery & Arthroscopy, International Society of Arthroscopy Knee Surgery and Orthopaedic Sports Medicine, Pediatric Orthopaedic Society of North America and Sociedad Latinoamericana de Artroscopia, Rodilla y Deporte attended. Physiotherapists and orthopaedic surgeons with clinical and research experience in the field, and an ethics expert with substantial experience in the area of sports injuries also participated. Injury management is challenging in the current landscape of clinical uncertainty and limited scientific knowledge. Injury management decisions also occur against the backdrop of the complexity of shared decision-making with children and the potential long-term ramifications of the injury. This consensus statement addresses six fundamental clinical questions regarding the prevention, diagnosis and management of paediatric ACL injuries. The aim of this consensus statement is to provide a comprehensive, evidence-informed summary to support the clinician, and help children with ACL injury and their parents/guardians make the best possible decisions.

GRANADA consensus on analytical approaches to assess associations with accelerometer-determined physical behaviours (physical activity, sedentary behaviour and sleep) in epidemiological studies
- 2022
-
In: British Journal of Sports Medicine. - : BMJ. - 0306-3674 .- 1473-0480. ; 56:7, s. 376-384

Journal article (peer-reviewed)abstract
- The inter-relationship between physical activity, sedentary behaviour and sleep (collectively defined as physical behaviours) is of interest to researchers from different fields. Each of these physical behaviours has been investigated in epidemiological studies, yet their codependency and interactions need to be further explored and accounted for in data analysis. Modern accelerometers capture continuous movement through the day, which presents the challenge of how to best use the richness of these data. In recent years, analytical approaches first applied in other scientific fields have been applied to physical behaviour epidemiology (eg, isotemporal substitution models, compositional data analysis, multivariate pattern analysis, functional data analysis and machine learning). A comprehensive description, discussion, and consensus on the strengths and limitations of these analytical approaches will help researchers decide which approach to use in different situations. In this context, a scientific workshop and meeting were held in Granada to discuss: (1) analytical approaches currently used in the scientific literature on physical behaviour, highlighting strengths and limitations, providing practical recommendations on their use and including a decision tree for assisting researchers decision-making; and (2) current gaps and future research directions around the analysis and use of accelerometer data. Advances in analytical approaches to accelerometer-determined physical behaviours in epidemiological studies are expected to influence the interpretation of current and future evidence, and ultimately impact on future physical behaviour guidelines.

- 2006
-
In: British Journal of Sports Medicine. - : BMJ. - 0306-3674 .- 1473-0480. ; 40:1, s. 25-29; discussion 25
-
Journal article (peer-reviewed)abstract
- OBJECTIVE:To measure the graded relation between cardiorespiratory fitness and sum of skinfolds, waist circumference, and blood pressure in children and adolescents participating in the European youth heart study.METHODS:The participants were 4072 children and adolescents (aged 9 and 15) from Denmark, Portugal, Estonia, and Norway. Cardiorespiratory fitness was indirectly determined using a maximal ergometer cycle test. The sum of four skinfolds, waist circumference, and blood pressure were assessed with a standardised protocol. Linear regression analysis was used to test the graded relation between cardiorespiratory fitness and the dependent variables adjusted for pubertal stage, sex, and country.RESULTS:A significant curvilinear graded relation was found between cardiorespiratory fitness and waist circumference and sum of skinfolds (partial r2 for cardiorespiratory fitness was 0.09-0.26 for the different sexes and age groups). Systolic and diastolic blood pressure also showed a curvilinear relation with cardiorespiratory fitness, and fitness explained 2% of the variance in systolic blood pressure. The difference in systolic blood pressure between the least and most fit was 6 mm Hg.CONCLUSION:A curvilinear graded relation was found between cardiorespiratory fitness and waist circumference, sum of skinfolds, and systolic blood pressure. The greatest difference in these health variables was observed between low and moderate fitness levels.

Sport Medicine Diagnostic Coding System (SMDCS) and the Orchard Sports Injury and Illness Classification System (OSIICS): revised 2020 consensus versions
- 2020
-
In: British Journal of Sports Medicine. - : BMJ PUBLISHING GROUP. - 0306-3674 .- 1473-0480. ; 54:7, s. 397-401
-
Journal article (peer-reviewed)abstract
- Coding in sports medicine generally uses sports-specific coding systems rather than the International Classification of Diseases (ICD), because of superior applicability to the profile of injury and illness presentations in sport. New categories for coding were agreed on in the International Olympic Committee (IOC) consensus statement: Methods for recording and reporting of epidemiological data on injury and illness in sports 2020. We explain the process for determining the new categories and update both the Sport Medicine Diagnostic Coding System (SMDCS) and the Orchard Sports Injury and Illness Classification System (OSIICS) with new versions that operationalise the new consensus categories. The author group included members from an expert group attending the IOC consensus conference. The primary authors of the SMDCS (WM) and OSIICS (JO) produced new versions that were then agreed on by the remaining authors using expert consensus methodology. The SMDCS and OSIICS systems have been adjusted and confirmed through a consensus process to align with the IOC consensus statement to facilitate translation between the two systems. Problematic areas for defining body part categories included the groin and ankle regions. For illness codes, in contrast to the ICD, we elected to have a taxonomy of organ system/region (eg, cardiovascular and respiratory), followed by an aetiology/pathology (eg, environmental, infectious disease and allergy). Companion data files have been produced that provide translations between the coding systems. The similar structure of coding underpinning the OSIICS and SMDCS systems aligns the new versions of these systems with the IOC consensus statement and also facilitates easier translation between the two systems. These coding systems are freely available to the sport and exercise research community.

Cardiovascular fitness modifies the associations between physical activity and abdominal adiposity in children and adolescents : The European Youth Heart Study
- 2010
-
In: British Journal of Sports Medicine. - London, United Kingdom : BMJ Publishing Group Ltd. - 0306-3674 .- 1473-0480. ; 44:4, s. 256-262
-
Journal article (peer-reviewed)abstract
- Objective: To examine the associations between physical activity (PA) and abdominal adiposity, as measured by waist circumference, in children and adolescents, and to test whether cardiovascular fitness (CVF) modifies these associations.Methods: PA components were measured by accelerometry in 1075 individuals aged 9 or 15 years old. CVF was measured by a maximal cycling test. Self-reported maternal educational level, body mass index, children's birth weight and television viewing were used as confounders.Results: Linear regression did not show any association between the PA variables and waist circumference, after controlling for sex, age and height. When stratifying by CVF level (low/high), time spent at vigorous PA was inversely associated with waist circumference (p≤0.05) in the low CVF group. Unexpectedly, in the high CVF group, the PA variables were positively associated with waist circumference (p≤0.05). In both groups, the results were unchanged after controlling for the confounders. CVF was inversely associated with waist circumference, after controlling for all PA variables (p≤0.01) and confounders (p≤0.01).Conclusion: CVF is inversely associated with abdominal adiposity and seems to modify the associations between PA and abdominal adiposity. In low-fit children and adolescents, time spent in vigorous PA seems to be the key component linked to abdominal adiposity. This finding should be considered in further development of lifestyle intervention strategies. The results found in the high-fit group need to be confirmed.

- Background: Sedentary behaviour is associated with impaired cognition, whereas exercise can acutely improve cognition.Objective: We compared the effects of a morning bout of moderate-intensity exercise, with and without subsequent light-intensity walking breaks from sitting, on cognition in older adults.Methods: Sedentary overweight/obese older adults with normal cognitive function (n=67, 67±7 years, 31.2±4.1 kg/m2 ) completed three conditions (6-day washout): SIT (sitting): uninterrupted sitting (8 hours, control); EX+SIT (exercise + sitting): sitting (1 hour), moderate-intensity walking (30min), uninterrupted sitting (6.5 hours); and EX+BR (exercise + breaks): sitting (1 hour), moderate-intensity walking (30min), sitting interrupted every 30min with 3min of light-intensity walking (6.5 hours). Cognitive testing (Cogstate) was completed at four time points assessing psychomotor function, attention, executive function, visual learning and working memory. Serum brain-derived neurotrophic growth factor (BDNF) was assessed at six time points. The 8-hour net area under the curve (AUC) was calculated for each outcome.Results: Working memory net AUC z-score·hour (95%CI) was improved in EX+BR with a z-score of +28 (−26 to +81), relative to SIT, −25 (−79 to +29, p=0.04 vs EX+BR). Executive function net AUC was improved in EX+SIT, −8 (− 71 to +55), relative to SIT, −80 (−142 to −17, p=0.03 vs EX+SIT). Serum BDNF net AUC ng/mL·hour (95%CI) was increased in both EX+SIT, +171 (−449 to +791, p=0.03 vs SIT), and EX+BR, +139 (−481 to +759, p=0.045 vs SIT), relative to SIT, −227 (−851 to +396).Conclusion: A morning bout of moderate-intensity exercise improves serum BDNF and working memory or executive function in older adults, depending on whether or not subsequent sitting is also interrupted with intermittent light-intensity walking.

Towards prevention of self-objectification in young female athletes on social media : instagram posting patterns of female elite athletes in aesthetic and non-aesthetic individual sports
- 2024
-
In: British journal of sports medicine. - : BMJ Publishing Group Ltd. - 1473-0480. ; 58:Suppl 2, s. 69-70
-
Conference paper (peer-reviewed)abstract
- Background Elite athletes are role models for young sportspersons regarding social media use. Self-objectification, including self-sexualizing, contributes to body dissatisfaction and body shame, especially in young females. For efficient prevention of self-objectification, knowledge is needed about elite athletes’ self-presentation on social media.Objective To compare social media postings indicative of self-objectification among female elite athletes in an aesthetic and a non-aesthetic individual sport and by age.Design Cross-sectional quantitative visual content analysis study.Setting Instagram on October 1st, 2021.Participants All Swedish elite female athletes aged 16 years or older with open Instagram accounts in figure skaters (n=26) and athletics (track and field) athletes (n=40).Assessment of Risk Factors The 30 most recently posted images were identified from each athlete’s Instagram account (Figure). Following exclusion of non-topical images, a panel (4 women/4 men) individually scored factors indicative of self-objectification in the remaining images. The scores were analyzed quantitatively by sport (figure skating/athletics) and age group (age-cut at 21 years).Main Outcome Measurements Proportion of sexually suggestive images in Instagram postings.Results In total, 1,869 images were analyzed; 669 posted by figure skaters and 1200 by athletics athletes. Seventy-four images (4%) were classified as containing sexually suggestive content. Figure skaters posted more images with sexually suggestive content (p=0.032) than athletics athletes (especially images with sexual posing (p=0.005) and sexualized body parts in focus (chest (p=0.049); hip-region (p=0.001)). Younger athletes published more images interpreted to contain sexual suggestion than older athletes (p<0.001) (especially images focusing on the chest (p=0.008)).
