Each summer, schools and general club teams hold training camps in summer resorts for a few days to a week or two, participating in training sessions and tournaments. For rugby players, Sugadaira in Nagano prefecture is a popular training camp sanctuary. Each year, hundreds of thousands of athletes and spectators gather in Sugadaira to cheer on student-athletes as they get ready for their fall and winter competition seasons. One of the primary reasons for Sugadaira’s popularity among teams is the number of athletic fields in the area. In total, there are 107 athletic fields (figure 1), most of which are managed by the lodges that provide housing and meals for the teams during their stay. Outside of the high-demand seasons by sports lovers, the area is rural and sparsely populated (population of 940, according to the national census report in 2020). The area has an average emergency medical service response time of 33.4 min due to its geographical characteristics (ie, highlands) that warrant the ambulance dispatch from towns at the foot of the mountains (national average: 10.3 min1). In 2021, a college student-athlete experienced cardiopulmonary arrest during a rugby match and was successfully resuscitated. This dramatic save was possible due to a seamless and efficient chain of survival facilitated by fortunate circumstances: the bystander was a cardiologist, an automated external defibrillator (AED) was accessible at a nearby facility within 3 min and favourable weather conditions allowed for the air ambulance service to reach the collapsed athlete.

This scoping review, accompanied by an evidence gap map, aims to systematically chart current literature on BFR’s impact on non-restricted muscles, summarise key outcomes and identify methodological trends to guide future research. Methods Searches were conducted in PubMed, Scopus and Web of Science. Studies included adults—healthy or with musculoskeletal conditions—undergoing BFR resistance training, with passive or active comparator groups in two-arm or multi-arm designs. Data focused on chronic physiological (eg, muscle properties) and physical fitness (eg, strength, power) adaptations. Risk of bias was assessed using RoB 2 (Cochrane Risk of Bias 2 tool) for randomised and ROBINS-I (Risk of Bias in Non-Randomised Studies - of Interventions) for non-randomised studies. Results From 1740 records, 19 studies (540 participants; 6 women) met the criteria. Intervention durations ranged from 2 to 12 weeks, with training frequencies of 2–6 sessions per week and cuff pressures of 50–270 mm Hg. The most reported outcomes were 1-repetition maximum strength, muscle cross-sectional area and thickness. The pectoralis major and shoulder rotators were the most frequently studied muscles. Most studies implemented BFR training two to three times weekly for an average of 8 weeks. Conclusions Evidence suggests BFR training may benefit non-restricted muscles, but variability in study protocols, small sample sizes and limited standardisation hinder broad conclusions. Future research should employ consistent methodologies, larger cohorts and extended interventions to enhance comparability and generalisability.

Methods Methods followed the Consensus Head Acceleration Measure Practices guidelines. This prospective observational cohort study involved 52 elite male players from four clubs in the first and third tiers of English football, and 20 elite female football players from two clubs in the first tier. Players wore iMGs during outfield training sessions to collect data. A linear mixed model was used to identify differences in heading metrics based on sex, age and header situations, analysing 13 distinct metrics related to heading frequency and intensity. Results The study recorded 1496 heading impacts across 63 training sessions. The mean peak (SD) heading intensity was 18.1 (8.5) g and 1068 (776) rad/s2, with a mean impact duration of 10.4 (8.9) ms. Male players had a mean peak linear acceleration (PLA) of 17.8 (8.2) g and a mean peak rotational acceleration (PRA) of 1025 (741) rad/s2. Females had a PLA of 20.1 (9.7) g and a PRA of 1374 (934) rad/s2. Significant sex differences were found for rotational acceleration, with female players showing higher values (p=0.015, 𝑛𝑝2=0.004), but not for linear acceleration (p=0.152, 𝑛𝑝2=0.001). Significant differences in PLA and PRA were also observed between different header situations, with the lowest values recorded for headers from throws. Conclusions This understanding of heading demands has important implications for player health and safety. The information can be used to inform training practices and quantification of heading loads.
