RESUMO
BACKGROUND: The fitness trainer could have an important role in the prevention of injuries among fitness attendants. In several Countries, including Italy, there is not a formal regulation about the qualification of fitness trainers. The aim of our study is to estimate the incidence of injuries in a sample of amateur fitness athletes training in Apulia (southern Italy) and evaluate if being the presence of a trainer graduated in Sports and Movement Science could be a protective factor for injuries. METHODS: This is a retrospective, cross-sectional study, carried out in a convenience sample of amateur athletes enrolled in 16 Apulian fitness centers. The survey was carried out by an anonymous self-administered questionnaire distributed and compiled in the gym. RESULTS: We enrolled 205 amateur athletes, of which 105/205 (51.2%) cared by a trainer graduated in Sports and Movement Science and 100/205 (48.8%) trained by a person with a qualification from Olympic Committee or Sport Federation. The incidence rate of injury ×1000 person-months of training is 6.1 (95%CI=4.4-8.1), 5.5 (95%CI=3.1-9.2) among athletes trained by graduated and 6.3 (95%CI=4.2-9.2) in ones trained by a person with a different qualification (IRR=1.1; 95%CI=0.6-2.3; P=0.348). CONCLUSIONS: Our study showed a mild lifetime prevalence of injury among subjects attending fitness activities (21%), higher among athletes trained by an instructor not graduated in Sports Science. This is a topic poorly investigated previously but very important in the future, in particular in the view of the diffusion of fitness worldwide.
