Growth-related and overuse injuries are commonly reported in young gymnasts. Two risk factors of these injuries are growth and maturation, and training load. However, little is known regarding current coaching knowledge and practice in relation to these risk factors. To help understand current knowledge and practice, 44 coaches of competitive, young gymnasts, from 3 gymnastics disciplines (men’s artistic, women’s artistic, trampoline) took part in focus groups. The focus groups explored the awareness, experience and practice of coaches in relation to growth and maturation, training load and injury in competitive, young gymnasts. Data were analysed manually using an inductive thematic approach to identify core themes. The findings showed that coaches were aware of the physical changes and injuries that occur during the adolescent growth spurt. Both psychological changes and skill loss/confusion were also identified as challenges during this time. The knowledge and practice of monitoring growth and maturation, and training load did however differ between disciplines. Sports science and medicine practitioners were recognised as key stakeholders in helping manage and reduce the risk of injuries during growth. There appears to be gap between coach knowledge of growth and maturation, and training load, and practices such as monitoring training load and growth. Educating coaches and further research in these areas will aid coaches in reducing the risk of injuries in young, competitive gymnasts.
In March 2020, following the outbreak of , the UK entered its first national lockdown as an attempt to reduce the spread of the virus. As a result, all organised sport was suspended, and during this time, young gymnasts, like many other athletes, were restricted to home-based exercise and training. Following the easing of restrictions, gymnasts in England, gradually followed by gymnasts in Northern Ireland, Wales, and Scotland, were able to return to training within a gym environment.
There is currently limited research exploring the relationship between growth, training load and injury in gymnasts. Twenty-one national level, trampoline gymnasts recorded training load and injury for 8-weeks. Percentage of predicted adult height (%PAH) was calculated using the Khamis-Roche method and used to define growth spurt status. Training load was calculated using the session rate of perceived exertion and analysed as differential loads and as a 7-day exponentially weighted moving average (EWMA7day). There was a significant non-linear association between %PAH and the probability of injury when adjusting for either training load metric (differential load, P = 0.015; EWMA7day; P = 0.008), with the highest injury risk estimated at ~90% PAH (circa growth spurt). The probability of injury significantly increased with increases in EWMA7day training load (RR: 1.88 95% CI: 1.21-2.91, P = 0.005) but not with differential load. No significant interaction between %PAH, training load and the probability of injury were observed. Data suggest that competitive trampoline gymnasts are at an increased risk of injury during the adolescent growth spurt or with higher weekly training loads. Coaches should be educated and encouraged to identify periods of rapid growth and monitor training load, to reduce the risk of injury.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
