Optimising exercise prescription for cancer-related fatigue, lean mass, physical function and muscle strength in women with breast cancer: a systematic review with dose-response network meta-analysis

Jun 23, 2026

The authors aimed to systematically review and analyze the dose-response relationship of different exercise modalities—aerobic, resistance, and combined exercise—on cancer-related fatigue, lean mass, physical function, and muscle strength in women with breast cancer during and after treatment. They found that combined exercise was most effective for reducing fatigue and increasing lean mass, while resistance exercise was superior for enhancing physical function and muscle strength, with significant benefits observed at relatively low exercise doses. The study highlights the potential for tailored exercise prescriptions to improve outcomes in this population.

Evaluating movement breaks as a public health strategy to mitigate the harms of prolonged sitting: a large-scale pragmatic intervention

Jun 23, 2026

This study investigates the effectiveness and feasibility of implementing brief, regular movement breaks as a public health strategy to counteract the negative effects of prolonged sitting. Conducted with over 19,000 adults, the findings indicate that movement breaks significantly improved psychosocial outcomes, such as reducing fatigue and enhancing positive affect, with hourly breaks providing the optimal balance between feasibility and effectiveness. The results support the potential of movement breaks as a viable intervention to mitigate the harms associated with sedentary behavior.

Factors associated with return-to-sport outcomes following pathogen-confirmed acute respiratory infections in athletes: AWARE X study

Jun 19, 2026

The authors aimed to identify factors influencing return-to-sport (RTS) outcomes in athletes following confirmed acute respiratory infections (ARinf). Their study found that RTS outcomes were significantly affected by the athlete's level of participation, the severity of the illness, and the specific pathogen involved, with amateur athletes and those with severe infections experiencing longer recovery times. The findings suggest that assessing illness severity and identifying the causative pathogen can enhance clinical decision-making regarding RTS.

GLP-1 receptor agonists and weight-loss strategies for individuals with obesity and hip or knee osteoarthritis: a scoping review

Jun 19, 2026

The authors conducted a scoping review to explore current weight-loss strategies for individuals with obesity and hip or knee osteoarthritis, particularly focusing on the role of glucagon-like peptide-1 receptor agonists (GLP-1-RAs). They found that while GLP-1-RAs are associated with significant weight loss and improved symptoms in knee osteoarthritis, evidence for their effectiveness in hip osteoarthritis is limited. The review suggests that GLP-1-RAs should be used as part of a comprehensive treatment approach rather than as standalone solutions.

Mental health in tennis: a cross-organisational hybrid summit-Delphi consensus process

Jun 18, 2026

The authors aimed to generate actionable recommendations for enhancing mental healthcare and promoting mental wellness among elite and junior tennis athletes. Through a hybrid summit and Delphi consensus process involving diverse stakeholders from the tennis community, they established two foundational principles and 25 recommendations across five key domains. This initiative serves as a framework for prioritizing mental health in tennis and offers a model for similar collaborative efforts in other high-performance sports.

Substance use patterns in elite athletes: a scoping review of alcohol, performance-enhancing drugs and other psychoactive substances

Jun 17, 2026

The authors conducted a scoping review to systematically map and synthesize the literature on substance use patterns among elite athletes, including recreational substances, performance-enhancing drugs (PEDs), and polysubstance use. They found that while alcohol was the most studied substance, the research exhibited significant gaps in methodology, conceptual understanding, and representation of diverse athlete populations. The authors advocate for future studies to adopt longitudinal designs and incorporate mental health frameworks to better address substance-related vulnerabilities in this demographic.

Longitudinal cohort study of the association between labral pathology and cartilage loss in high-impact athletes: the FORCe study

Jun 17, 2026

The study aimed to investigate whether labral tears in high-impact athletes are associated with accelerated cartilage loss over time. The findings indicated weak-to-moderate associations between baseline labral tears and subsequent cartilage loss, suggesting that while labral tears may contribute to cartilage deterioration in young athletes, other factors also play a significant role. Further research is needed to develop strategies for preventing cartilage loss in this population.

Ready to respond? Safeguarding structures in European National Olympic Committees

Jun 11, 2026

The authors aimed to assess the safeguarding structures and organizational readiness of 20 European National Olympic Committees (NOCs) to respond to interpersonal violence. Their findings revealed that while most NOCs have appointed safeguarding officers and some established reporting mechanisms, significant gaps in policy implementation, referral pathways, and staff capacity remain. The study highlights the need for improved safeguarding infrastructure and resources to enhance the readiness of NOCs to effectively address and respond to incidents of harm.

Optimal 24-hour movement behaviour compositions across trimesters and risk of hypertensive disorders of pregnancy: the Pregnancy 24/7 cohort study

Jun 10, 2026

This study aimed to identify optimal 24-hour movement behavior compositions during pregnancy that are associated with a lower risk of hypertensive disorders of pregnancy (HDP). Analyzing data from 470 participants, the authors found that lower sedentary behavior and higher light-intensity physical activity were significant predictors of reduced HDP risk. These findings suggest that modifying daily movement behaviors could serve as effective intervention strategies to mitigate HDP risk.

Post-concussion screen time duration and type and its association with symptom resolution in youth aged 11-17 years

Jun 9, 2026

The authors aimed to investigate the relationship between screen time duration and type during the first week post-concussion and the time to symptom resolution in youth aged 11-17 years. They found that moderate screen time of approximately 141 minutes per day was associated with a faster rate of symptom resolution compared to both lower and higher screen time levels. The study suggests that clinicians might recommend a balanced level of screen use rather than complete avoidance to aid in recovery from concussion.
