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 data used in this study are managed by the Korean government and can only be accessed by those with permission from the Korean government.","PeriodicalId":9276,"journal":{"name":"British Journal of Sports Medicine","volume":"37 1","pages":""},"PeriodicalIF":18.4,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142986718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

This includes fostering emotional, psychological and social growth alongside physical recovery. Social-structural and interpersonal barriers hinder adherence to exercise maintenance. A lack of psychological and social support significantly impacts adherence to exercise interventions, both during and after rehabilitation, which is essential for initiating and sustaining health-related behaviours.2 4 5 Habitual behaviours, deeply ingrained and automatic, inhibit new interventions, highlighting the need for targeted, context-specific strategies.4 Enhancing the expertise of rehabilitation professionals to use theoretical models promoting holistic approaches can help break down entrenched beliefs and foster new cultural understandings about rehabilitation.6 Compliance has been an issue in physiotherapy since the 1970s.7 The role of rehabilitation in patients’ lives should not be reduced to just ‘medicine’. Such programmes ought to integrate into a patient’s life, seeking not just health (mostly physical)8 results but also personal growth, emotional enhancement and positive social connections. The motivation for individuals to adhere to a rehabilitation programme, ensuring exercise maintenance, should not be dictated only by fear of health deterioration, physical performance or other external factors.

I was a sophomore student at Station Camp High School in Gallatin, Tennessee. Like every morning, the bell would ring, students would take their seats and our teacher (Coach Bartlett) would begin class. It is interesting how we define seemingly meaningless times in our lives. We even have phrases like ‘killing time’ to characterise these throwaway moments. I looked down at my watch. I had plenty of time to eat my strawberry Pop Tart before class started. Coach Bartlett worked hard to challenge students but was also flexible and laid-back enough to let students eat in his classroom before class.

We identified differences in force-sharing between patients with Achilles tendinopathy and healthy controls, assessed Achilles tendon property changes over time, compared responders from non-responders throughout rehabilitation and investigated the impact of incorporating Achilles (sub)tendon characteristics into musculoskeletal models. ### Why did I do it? The Achilles tendon is connected to, and loaded through force production of the three triceps surae muscle forces: the soleus (SOL), the gastrocnemius lateralis (GL) and medialis (GM). Tendon remodelling occurs due to repetitive, high or unusual loads as internal tendon strains will increase, leading to microtrauma, where the arrangement of collagen fibres within the tendon gets disorganised. This common overuse injury, known as Achilles tendinopathy, affects both competitive and recreational athletes. Various structural and functional changes in the tendinopathic tendon are observed compared with healthy tendons, for example, increased volume and cross-sectional area, and decreased stiffness, …","PeriodicalId":9276,"journal":{"name":"British Journal of Sports Medicine","volume":"25 1","pages":""},"PeriodicalIF":18.4,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142935102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
