Method A systematic review with meta-analysis was carried out. Five bibliographic databases were searched to August 2023. Results Forty-two studies were included (n=46 694). Overall, cancer patients with high muscle strength or CRF levels (when dichotomised as high vs low) had a significant reduction in risk of all-cause mortality by 31–46% compared with those with low physical fitness levels. Similarly, a significant 11% reduction was found for change per unit increments in muscle strength. In addition, muscle strength and CRF were associated with an 8–46% reduced risk of all-cause mortality in patients with advanced cancer stages, and a 19–41% reduced risk of all-cause mortality was observed in lung and digestive cancers. Lastly, unit increments in CRF were associated with a significant 18% reduced risk of cancer-specific mortality. Conclusion High muscle strength and CRF were significantly associated with a lower risk of all-cause mortality. In addition, increases in CRF were associated with a reduced risk of cancer-specific mortality. These fitness components were especially predictive in patients with advanced cancer stages as well as in lung and digestive cancers. This highlights the importance of assessing fitness measures for predicting mortality in cancer patients. Given these findings, tailored exercise prescriptions to improve muscle strength and CRF in patients with cancer may contribute to reducing cancer-related mortality.

Methods We analysed data from the Adolescent Behaviour and Experiences Survey, a nationally representative survey of adolescents in the USA. Our independent variables were history of concussion in the 12 months preceding survey completion; self-reported weekly physical activity (days per week with >60 min of physical activity, 0–7 scale); substance use over the past 30 days (yes vs no) and illicit drug use throughout lifetime (yes vs no). Our dependent variable was participant-reported sadness/hopelessness over the past 12 months (yes vs no). Results Among 7499 adolescents (9th–12th grade, 50.4% female), reporting one or more concussions over the past year was not associated with the odds of depressive symptoms (OR: 1.13, 95% CI: 0.93 to 1.37, p=0.21). Each additional day of physical activity per week was associated with a lower odds of depressive symptoms (OR: 0.91; 95% CI: 0.89 to 0.94; p<0.0001). Illicit drug use (OR ever vs never: 2.48; 95% CI: 1.96 to 3.13; p<0.0001) and substance use (OR yes vs no: 2.77; 95% CI: 2.34 to 3.29; p<0.001) were associated with a higher odds of depressive symptoms. Conclusions Adjusting for physical activity, substance use and illicit drug use, concussion was not significantly associated with depressive symptoms. This novel discovery informs clinicians as they counsel adolescents with concussion; future research should examine physical activity and avoidance of substance/illicit drug use as postinjury recommendations in an effort to lower the risk of depressive symptoms.

These interventions offer a range of benefits, including increased physical activity, improved fitness and strengthened social connections, addressing the physical, psychological and social challenges faced by individuals with SMD.4 However, access to such interventions remains limited by psychosocial and structural barriers such as insufficient resources, support and motivation, hindering their implementation and integration into patient care. To address this need, PowerONyou was started in 2013 at the University Pablo de Olavide, as a research project by the CTS-948 group, ‘Physical Activity, Health and Sports’. Over time, it has evolved into a community intervention programme, implemented in mental health centres and sociohealth environments in collaboration with healthcare professionals.

To optimise athlete development and performance outcomes, the maintenance and support of physical and psychological health of an athlete are essential. Therefore, limiting injury and illness (including mental health conditions) requires consideration across an athlete’s development journey.2 Contextual-driven prevention strategies addressing the complex and multifactorial nature of injury and illness occurrence are a part of the socioecological system, which includes individual, sociocultural and environmental levels.3 This editorial proposes an illustration of an integrative and empowering approach to athlete development in any sport aiming to grow an athlete holistically for long-term health and performance. The greenhouse concept (figure 1) highlights the analogy of nurturing elite athletes ( plants ) from the development stage ( inside the greenhouse ) to peak performance ( outside of the greenhouse ), by providing a multidisciplinary supported pathway ( greenhouse with gardeners ) of both stability and challenge.1 Consideration is given to each athlete’s unique contextual and environmental requirements described as greenhouse characteristics for optimal growth and development (just like a plant ) to grow robustness and flourish as an elite athlete.

Recent studies indicate that the Copenhagen Hip and Groin Outcome Score (HAGOS), in the original or the revised scoring format, and the Oxford Hip Score (OHS) may be relevant for use in patients with hip-abductor tendon pathology. The objective of this study was to assess the validity of the Danish version of the HAGOS, the revised HAGOS, and the OHS psychometrically in patients with hip-abductor tendon pathology. This involved the six subscales in the original and the revised version of HAGOS, the standard one-factor scoring of the OHS and the two-factor scoring of the OHS. Methods We included individual responses to HAGOS and OHS from 210 patients with hip-abductor tendon pathology (17 men; 193 women; median age 56 years, range 18–91, IQR 48–65). Overall fit, model fit, individual item fit and measurement invariance were examined using confirmatory factor analysis (CFA) and item response theory. Results CFA rejected psychometric validity of three original HAGOS subscales (symptoms, pain, physical function in sport and recreation) (p<0.0001) and the OHS (p<0.0001), whereas the revised scoring format for HAGOS subscales fit adequately. Results indicate a notable discrepancy between observed and expected scores on OHS item 10 in the patient group. Conclusion The original HAGOS and OHS are not psychometrically valid, but the revised HAGOS scoring format is an appropriate PROM for patients with hip-abductor tendon pathology. The OHS would need slight adjustment before being used in patients with hip-abductor tendon pathology. Data are available upon reasonable request.

Data extraction from the articles included the researcher’s names, sex/gender, total number of authors, number of black authors, their position in the author list, publication year, article title and type and digital object identifier. Sex/gender and race/skin colour were identified using publicly available photographs and methodologies aligned with previous studies and Brazilian racial heteroidentification practices. Results The analysis included 1737 articles and 11 158 authors. Only 144 (1.30%) authors were identified as black, of which only 38 were women, corresponding to 0.34% and 26.4% of total authors and total black authors, respectively. When considering authorship positions, only 16 (0.92%) were the first author and 19 (1.09%) were the last (senior) author. Merely 13 (0.75%) articles had two or more black authors.

However, recommending moderate to vigorous PA (MVPA) to patients with recent acute coronary syndrome (ACS) raises concerns owing to potential risk of recurrent ACS or fatal arrhythmias. This study investigated the association between longitudinal PA changes following an ACS diagnosis and subsequent cardiovascular outcomes, including non-fatal coronary events, non-fatal stroke and cardiovascular mortality. Methods This longitudinal cohort study used Korean National Health Insurance Service data from 2010 to 2017, comprising 30 840 patients diagnosed with ACS following invasive coronary angiography or bypass surgery. Leisure-time PA was self-reported, with the frequency and intensity measured weekly. The primary endpoint was a composite of nonfatal coronary events, non-fatal stroke and cardiovascular mortality. Multivariable Cox proportional hazards regression models assessed the association between PA changes and cardiovascular outcomes. Results Among patients with ACS (mean age: 60±11 years, men: 81.3%), mean PA levels increased from 544±556 metabolic equivalent task (MET)-min/week to 594±567 MET-min/week. Over 6.7 years of median follow-up, 5639 cardiovascular events occurred. Increased PA was associated with lower cardiovascular event risk (HR 0.95, 95% CI 0.92 to 0.98). Consistent MVPA pre-ACS and post-ACS reduced cardiovascular event risk (HR 0.87, 95% CI 0.79 to 0.96) and MVPA initiation showed a modest risk reduction (HR: 0.91, MET-min/95% CI 0.82 to 1.01). Conclusions Longitudinal increases in self-reported PA, maintenance of MVPA and possibly MVPA initiation after ACS reduced the risk of cardiovascular events. Initiating or maintaining MVPA could be an important strategy in improving cardiovascular outcomes following ACS. Data are available on reasonable request.

The definitions used in sports injury epidemiology have received much attention,1 2 as have the required sport-specific data fields3 and, recently, the inclusion of female-specific considerations.4 Voluntary informed consent is key when undertaking research with an opt-in rather than opt-out system in place and is typically required to legally comply with data protection and processing regulations (eg, General Data Protection Regulation in Europe).5 This can pose challenges to sports injury epidemiology where data may be recorded for internal medical purposes, but not all data can and or should be used for research purposes. Consent can be obtained in different ways, such as consent for sharing data for research purposes when athletes sign contracts with a club or project-specific consent whereby the research team seek consent directly from athletes. It is likely that sports injury epidemiology studies use different methods based on country-specific data laws, how data are collected and the partnerships in place conducting the research. Regardless, published sports injury epidemiology research states consent was obtained from athletes (eg,6 7); however, many studies do not report the proportion of consent within the cohort. For example, in a squad of 50 athletes, how many will provide voluntary informed consent? When an athlete does not grant consent, their injuries will not be included in the numerator part of injury incidence (eg, number of injuries in a squad during a season). However, understanding how many of the cohort provide consent is important for calculating the denominator (exposure) in time-based injury incidence.
