The Cardiac Health in Breast Cancer study is a two-arm, single-centre, randomised controlled trial investigating the impact of an exercise programme on cardiac changes in patients with breast cancer undergoing cardiotoxic cancer therapy. 48 females with breast cancer will be randomised to either a 12-month intervention group (IG) or a control group (CG). The IG will receive a combination of supervised high-intensity interval training (HIIT) and high-intensity resistance training (HIRT) for 6 months, while the CG will follow WHO guidelines for physical activity independently.

The primary endpoint is the occurrence of symptomatic or asymptomatic CTRCD at the time points of examination, detected by cardiac imaging, which may be mitigated by structured physical exercise.

To become or remain a professional esports player, individuals practice video gaming for several hours a day while remaining in a sitting posture which may not only lead to a decrease in training quality in the short term (eg, due to cognitive fatigue) but also put them at a higher risk for negative health events in the long-term (eg, overuse injuries). Thus, interrupting periods of prolonged video gaming in a sitting posture with acute physical exercise is strongly recommended for esports players even though the optimal dosage of acute physical exercise breaks remains unclear. To address this gap, we propose in this viewpoint that traditional concepts of exercise prescription and dosage determination using the variables frequency, intensity, time (also referred to as duration) and type of physical exercise (ie, abbreviated with the acronym FITT) should be complemented by the variable density which characterises the timing of consecutive bouts of acute physical exercise during an esports session.</p>","PeriodicalId":47417,"journal":{"name":"BMJ Open Sport & Exercise Medicine","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11499780/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142510305","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 data inputted were screened daily by the lead event physician and UCI medical delegate.</p><p><strong>Results: </strong>Throughout 5 days of the championships, 10.4% of the 230 cyclists sustained at least one injury. The overall injury incidence rate was 3.3 (95% CI 3.1 to 3.5) per 100 rides. The incidence rates were higher in the training 4.3 (95% CI 4.0 to 4.6)/100 rides than in the racing 2.2 (95% CI 2.1 to 2.3)/100 rides. There was a greater incidence of injury in female cyclists in the training 5.8 (95% CI 5.0 to 6.6)/100 rides and racing 4.5 (95% CI 3.9 to 4.9)/100 rides compared with male cyclists. Female cyclists experienced more severe injuries, with an average of 12.6 (±14, 95% CI 5.66 to 19.54) days lost to injury compared with 5.5 (±1.6 95% CI 1.89 to 9.11) seen in male cyclists. The main event medical actions were lifting, immobilisation and helmet removal.</p><p><strong>Conclusion: </strong>This study provides insights into the risk of injury to athletes within DHMTB. Our findings suggest more focus should be placed on the female DHMTB athlete. Additionally, this study provides unique information about common medical actions required of medical professionals working at DHMTB events and the importance of pre-event scenario training.</p>","PeriodicalId":47417,"journal":{"name":"BMJ Open Sport & Exercise Medicine","volume":null,"pages":null},"PeriodicalIF":3.9,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11474835/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142477615","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}
