In Phase I, healthy adults aged between 18 and 45 years (n=104) will be recruited for an intervention trial that involves exposure to one of the four stressors: heat, musculoskeletal, psychosocial or sleep deprivation. Biomarkers will be identified from molecular markers in biological samples (eg, blood, saliva, sweat and stool), physiological measures and psychological assessments to predict cognitive and physical performance under stress. A within-subjects design will determine changes in molecular and non-molecular markers before and after stress exposure. In Phase II, we will use the biomarkers identified in Phase I to develop a wearable sensor to predict and monitor human performance under stress.","PeriodicalId":47417,"journal":{"name":"BMJ Open Sport & Exercise Medicine","volume":"11 1","pages":"e002410"},"PeriodicalIF":3.9,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11784218/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143081676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pre- and postintervention measures included: self-rated health, parents' occupation, psychological distress, nutritional status and PA levels. The overall intervention effect was estimated using linear regression method, and heterogeneity in intervention effect was assessed by modelling complex variance.Results: Group-based exercise intervention significantly increased total PA time by more than 10 metabolic equivalents (METS) hours per week compared with individual-based exercise control group. When considering different types of activities, the intervention effect was stronger for vigorous activity (increase by almost 6 METS hours per week) than walking activity (2.5 METS hours per week). The change in moderate activity level was not significant after covariate adjustment. In addition, intervention was also effective in reducing sedentary hours. Finally, when complex level-1 heterogeneity was modelled by intervention status, we found substantially larger variance in the intervention group compared with the controls, indicating presence of heterogeneous treatment effect.Conclusions: This study discusses major implications of different ways of exercising among youths from a health, educational and sport perspective. Intervention and policies that leverage school social capital might serve as an avenue for health promotion in youth.","PeriodicalId":47417,"journal":{"name":"BMJ Open Sport & Exercise Medicine","volume":"11 1","pages":"e002024"},"PeriodicalIF":3.9,"publicationDate":"2025-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11781084/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143081554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the emergency readiness for SCA in German amateur football clubs.Methods: A cross-sectional survey of 253 German amateur football clubs (fifth division and lower) was conducted between January and August 2023. Club representatives participated in a 30-point questionnaire on automated external defibrillator (AED) availability, visibility, purchase, usage, frequency of staff trained in cardiopulmonary resuscitation (CPR) and AED usage, regular CPR and AED training, and the existence of an emergency action plan (EAP).Results: 161 of 253 eligible clubs (64% response rate) participated. An AED was available in 48/161 (30%) clubs. 46 of 161 clubs (29%) had no CPR-trained staff. A high availability of CPR- and AED-trained staff (>75% likelihood of being present at the pitch) was more likely during a match (61% and 84%) than training (40% and 51%), respectively. Retrospectively, over 7 years, five clubs reported that CPR-trained staff used an AED, resulting in a survival rate of 80%. 16 clubs (10%) had an EAP in the event of an SCA.Conclusion: German amateur football clubs show low emergency readiness for SCA despite a promising survival rate when an AED is used by CPR-trained staff on-site. Regular CPR and AED training for club members, increased availability of AEDs, and the development of EAPs might be beneficial in responding adequately to an SCA during football training and matches.","PeriodicalId":47417,"journal":{"name":"BMJ Open Sport & Exercise Medicine","volume":"11 1","pages":"e002274"},"PeriodicalIF":3.9,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11781088/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143081546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Team physiotherapists recorded injuries using an online surveillance system, classifying them by location, type, mode, mechanism and impact, including severity (time-loss days, TL) and medical attention days (MA). Injury incidence (I) and TL/MA injury burden were calculated per 1000 player hours. χ2 analysis compared match and training differences.Results: Thirty-nine players sustained 70 injuries (n=35 match, 35 training). Match incidence exceeded training (I=41.12 vs 1.10 injuries). Acute injuries were higher in matches (27 vs 17), while overuse injuries were higher in training (18 vs 3; p=0.001). Contact injuries were higher in matches (21 vs 7), and non-contact injuries were higher in training (10 vs 6; p=0.028). Acute ankle ligament injuries in matches caused substantial TL burden (411.7 days lost), while overuse lower leg injuries in training led to high MA burden (13.8). Anterior cruciate ligament (ACL) injuries were infrequent but burdensome (TL 496). The centre position sustained the most injuries (41%).Conclusion: This study underpinned implementing the first injury surveillance system in the elite UK netball competition, revealing match injury rates ~40 times higher than in training, with distinct injury characteristics. Findings suggest that prevention should target acute lower limb injuries and overuse conditions. Further research should assess the impact of playing with overuse injuries.","PeriodicalId":47417,"journal":{"name":"BMJ Open Sport & Exercise Medicine","volume":"11 1","pages":"e002324"},"PeriodicalIF":3.9,"publicationDate":"2025-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11781087/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143081669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All age groups, genders and levels of play were represented.Results: Examination of 19 studies with male (60%) and female players (41%) at different player levels (age: 10-50 years). The mean injury incidence was between 1 and 4 injuries/1000 hours, whereby the incidence in the studies that were only carried out with elite players tended to be at the upper end. Lower body injuries occurred most frequently (41%-92%), including strains (11%-64%), sprains (10%-61%), tendinopathy (6%-14%) and stress fractures (5%-11%). There was a high proportion of overuse injuries (25%-74%) and a predominance of mild and moderate injuries (73%-100%). The following risk factors can only be cautiously emphasised due to the heterogeneous results: The risk of injury increases with increasing level of play and a history of injury.Conclusion: Young players with a history of injury quickly moving to higher competition classes must be targeted with the highest injury prevention priority.

The Acti-Pair 2 study is an interventional, comparative, multicentre, randomised, stepped-wedge cluster study. The control group will consist of patients being followed for prostate cancer and receiving advice and recommendations for PA during consultations to make patients more active in their daily lives (=usual practice, PA to be performed independently at home). The intervention group will consist of patients being followed up for prostate cancer and benefiting from the Acti-Pair programme, which combines three interventions: (1) motivational support from a peer; (2) construction of a personalised and realistic project and (3) support from health and adapted PA professionals.

In Germany, smoking prevalence is high at around 30%, and only 45% achieve the WHO recommendation for physical activity (PA). Understanding how smoking and physical inactivity co-occur can inform interventions targeting these behaviours.Methods: We analysed data from 4073 adults (≥18 years) participating in a national household survey between April and July 2022. We tested the association between PA level (not=reference/low/medium/very active) and smoking status (never=reference/ex/current smoker). Among current smokers, we tested associations between PA level and cigarettes smoked per day, time spent with and strength of urges to smoke and motivation to stop smoking.Results: Overall, 29.9% (95% CI=28.5; 31.4) reported no leisure-time PA; among current smokers, it was 39.8% (95% CI=37.3; 42.4). Higher PA levels were associated with lower odds of being a current versus never smoker (OR=0.74, 95% CI=0.69; 0.79). Among current smokers, higher PA levels were associated with smoking fewer cigarettes per day (β=-0.98, 95% CI=-1.39; -0.56), weaker urges to smoke (OR=0.81, 95% CI=0.74; 0.89) and higher motivation to stop smoking (OR=1.13, 95% CI=1.02; 1.24). The association between PA and time spent with urges to smoke was not statistically significant (OR=0.93, 95% CI=0.85; 1.02).Conclusion: People who are more physically active are less likely to smoke. Current smokers with higher PA levels smoke less, are less dependent and are more motivated to quit. Further research is required to determine whether these associations are causal and, if so, whether interventions to increase PA could help people to quit smoking.","PeriodicalId":47417,"journal":{"name":"BMJ Open Sport & Exercise Medicine","volume":"10 4","pages":"e002087"},"PeriodicalIF":3.9,"publicationDate":"2024-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11667452/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142886353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
