Objective To examine sex differences in the dose–response association of VILPA with major adverse cardiovascular events (MACE) and its subtypes. Methods Using multivariable-adjusted cubic splines, we examined the associations of daily VILPA duration with overall MACE and its subtypes (incident myocardial infarction, heart failure and stroke) among non-exercisers (individuals self-reporting no leisure-time exercise and no more than one recreational walk per week) in the UK Biobank. We also undertook analogous analyses for vigorous physical activity among exercisers (individuals self-reporting participation in leisure-time exercise and/or recreational walking more than once a week). Results Among 13 018 women and 9350 men, there were 331 and 488 all MACE, respectively, over a 7.9-year follow-up. In women, daily VILPA duration exhibited a near-linear dose–response association with all MACE, myocardial infarction and heart failure. In men, dose-reponse curves were less clear with less evidence of statistical signifigance. Compared with women with no VILPA, women’s median daily VILPA duration of 3.4 min was associated with hazard ratios (HRs; 95% confidence intervals) of 0.55 (0.41 to 0.75) for all MACE and 0.33 (0.18 to 0.59) for heart failure. Women’s minimum doses of 1.2–1.6 min of VILPA per day were associated with HRs of 0.70 (0.58 to 0.86) for all MACE, 0.67 (0.50 to 0.91) for myocardial infarction, and 0.60 (0.45 to 0.81) for heart failure. The equivalent analyses in UK Biobank’s accelerometry sub-study exercisers suggested no appreciable sex differences in dose–response. Conclusions Among non-exercising women, small amounts of VILPA were associated with a substantially lower risk of all MACE, myocardial infarction and heart failure. VILPA may be a promising physical activity target for cardiovascular disease prevention, particularly in women unable or not willing to engage in formal exercise.

Methods Male athletes ages 15–30 years presenting to a sports medicine clinic at two tertiary care centres were invited to complete a survey about athlete health and well-being. Participants were divided into low EA and adequate EA groups based on survey responses. The associations between low EA and REDs outcomes were evaluated using χ2 tests and ORs were calculated using binomial logistic regression (significance: p<0.05). Results Low EA was associated with increased frequency of self-reported immunological, metabolic, psychological, cardiovascular and gastrointestinal dysfunction; reduced endurance performance, response to training, judgement, coordination and muscle strength; and increased irritability and depression. Low EA athletes were more likely to have self-reported cardiovascular dysfunction (OR 2.87, 95% CI 1.56 to 5.26) and psychological illness (OR 3.23, 95% CI 1.91 to 5.41), decreased training response (OR 2.64, 95% CI 1.38 to 5.03) and endurance performance (OR 2.26, 95% CI 1.13 to 4.52) and were less likely to have self-reported gonadal dysfunction (OR 0.49, 95% CI 0.30 to 0.81), than adequate EA athletes (p<0.05).

Conducting such research presents unique considerations for researchers, particularly in relation to supporting participant and researcher well-being. Similarly, approaching this sensitive topic with clear definitions of IV in sport and an understanding of trauma- and violence-informed care (TVIC) is paramount to the protection and care of everyone involved in the research. The landscape for researching IV in sport that has rapidly emerged to investigate its determinants from various lenses including ethical, sociological, psychological, criminological and organisational.1 2 The siloed nature of research on IV in sport also has led to inconsistency in terminology, hindering effective communication and collaboration within and outside the field. The terms used to describe and study IV in sport have a profound impact on how the problem is communicated and understood. The use of diverging definitions creates challenges for determining what is within or outside the scope of research, limits our ability to meaningfully compare prevalences and experiences reported across projects, and impacts methodological considerations such as the effective recruitment of participants. Currently, terms such as maltreatment, non-accidental violence, harm, harassment, abuse and IV are used interchangeably, and clarification on the use of terminologies is essential.

The aim of this study was to evaluate the diagnostic effectiveness of SMHAT-1 supplemented by a brief, in-person clinical intake interview in evaluating the prevalence of mental health concerns in elite athletes. Methods Sections 1 and 2 from SMHAT-1 were administered in person during the routine biannual medical check-up for Olympic athletes at the National Centre for Sports Medicine in Poland. Immediately after completing the measures, all athletes were interviewed by qualified psychologists who evaluated their mental health and provided recommendations. Results A total of 1121 elite athletes (545 female, 576 male) aged 18–53 (M=24.39, SD=5.09) were evaluated 2–8 months before the 2024 Paris Olympic Games; 72.4% scored above the triage threshold and 51% were positively screened in SMHAT-1’s section 2. Based on the subsequent mental health evaluation, only 9.5% showed signs of persistent mental health concerns and required referral to a mental health specialist. In 24.2%, their distress levels/symptoms were assessed as occasional and normal in relation to demands, and they underwent a psychoeducational intervention or were advised to consult a sports psychologist. Female athletes scored significantly higher in most questionnaires. Conclusion SMHAT-1 proved a useful addition to the routine medical check-ups for elite athletes.

Methods During 10 international outdoor athletic championships from 2007 to 2022, in-competition injuries were collected by medical teams and local organising committees. UTCI was extracted hourly from a global reanalysis of observed atmospheric conditions during each championship. We performed Poisson regressions with incidence rates (number of injuries per 1000 athlete starts) as outcomes and UTCI as a predictive variable adjusted for sex, for all and time-loss injuries, for different injured tissue types (ie, muscle, tendon, ligament, articular, bone and skin) and specific discipline (ie, sprints, hurdles, jumps, throws, middle distance, long distance, marathon and race walking). Results A total of 1203 in-competition injuries were reported for 29 579 athlete starts. For all in-competition injuries (ie, all injured tissue types and all disciplines), higher UTCI was associated with lower incidence rates for time-loss injuries (IRR=0.98, 95% CI 0.97 to 0.98) but not for all injuries (IRR=1.00, 95% CI 1.00 to 1.01). Based on injured tissue type with all disciplines included, higher UTCI was associated with lower incidence rates for all (IRR=0.97, 95% CI 0.97 to 0.98) and time-loss (IRR=0.96, 95% CI 0.96 to 0.96) muscle injuries. Based on the specific discipline, higher UTCI was associated with lower incidence rates for all and time-loss muscle injuries for sprints (IRR=0.95, 95% CI 0.95 to 0.96, and IRR=0.94, 95% CI 0.93 to 0.94, respectively), hurdles (IRR=0.97, 95% CI 0.96 to 97, and IRR=0.95, 95% CI 0.94 to 0.96, respectively) and throws (IRR=0.97, 95% CI 0.97 to 0.98). Conclusions Higher feel-like temperatures were associated with a decreased risk of time-loss and muscle injuries, particularly in sprints, hurdles and throws.

Methods Injury and exposure data were captured over 20 seasons using a prospective cohort design. Knee injury incidence, days’ absence and burden were recorded for each injury type and by pitch surface type for match and training. Results The rate of knee injury in matches was 9.8/1000 hours (95% CIs 9.3–10.3). Mean days lost were 50 (95% CI 46 to 53) in matches and 51 (95% CI 44 to 57) in training. In matches, medial collateral ligament injuries were the most common, while anterior cruciate ligament (ACL) injuries had the highest mean severity and burden. There was no significant change in the count of knee injuries over time; however, average severity increased significantly (annual change: 2.18 days (95% CI 1.60 to 2.77); p<0.001). The incidence of match knee injury was 44% higher on artificial pitches than grass pitches (incidence rate ratio: 1.44 (95% CI 1.21 to 1.69); p<0.01), with no significant difference in severity between surfaces. In matches, the tackle was the event most commonly associated with knee injuries for all diagnoses, except ACL injuries (running). In training, running was a more common injury event than the tackle. Conclusion Knee injuries in matches are common and severe in English professional men’s rugby union. Despite an increased focus on player conditioning and injury prevention throughout the study period, rates of knee injury remained stable, and resulting days’ absence increased.

Specifically, to estimate the (1) direction and strength of the association; (2) risk of spinal pain onset and (3) effect on spinal pain prognosis. Design Systematic review with meta-analysis. Data sources Electronic searches of MEDLINE, Embase, CINAHL and Web of Science up to 23 March 2023. Eligibility criteria for selecting studies Reports estimating the effect of sedentary behaviour on spinal pain in young people (≤19 years). Results We included 129 reports, 14 were longitudinal (n = 8 433) and 115 were cross-sectional (n > 697 590). We incorporated 86 studies into meta-analyses. (1) From cross-sectional data, we found low certainty evidence of a small positive association between sedentary behaviour and spinal pain (adjusted odds ratio 1.25 (95% CI 1.17 to 1.33), k = 44, n > 92 617). (2) From longitudinal data, we found low certainty evidence of no increased risk for the onset of spinal pain due to sedentary behaviour (adjusted risk ratio 1.07 (95% CI 0.84 to 1.35), k = 4, n = 1 292). (3) No studies assessed prognosis. Conclusion Cross-sectional data suggest minimally higher odds of spinal pain for children and adolescents who engage in greater sedentary behaviours. However, longitudinal data do not support a causal relationship, indicating that sedentary behaviour does not increase the risk for onset of spinal pain. Due to the low certainty of evidence, these findings must be interpreted with caution. We found no evidence of the effect sedentary behaviour has on spinal pain prognosis in children and adolescents, highlighting a considerable gap in the literature.
