A relação entre carga de treinamento e lesões em atletas profissionais de voleibol do sexo masculino: estudo prospectivo durante três temporadas

Abstract

The objective of this thesis was to analyze the relationship between training load and injuries in professional male volleyball athletes. The sample consisted of 43 male volleyball players (23.04 ± 5.23 years, 192.99 cm, 88.97 ± 12.26. kg) from a team that competed in national level tournaments for three seasons. This is a longitudinal, prospective, and observational study carried out during three seasons of a professional male volleyball team. Data on training load and injuries were collected daily. The monitoring of the Training Load was carried out using the Session Rating of Perceived Exertion method and the ACWR was calculated in different ways. The International Volleyball Federation Injury Surveillance System was used to record injuries. 13283 hours were counted during 8021 individual training and game sessions. The injury incidence was calculated from the number of injuries per 1000 hours of training. Injury odds ratios associated with different Training Load metrics were estimated using logistic models with parameters calculated from generalized estimating equation (GEE). In this period there were 108 injuries and a total incidence of 8.13 injuries / 1000 h. The Pre-Season had a higher training load and a higher incidence of injuries compared to the competitive period. Among all the analyzes of the Training Load metrics, the highest values of risk of injury were observed in ACWR calculated from the exponential mean, coupled and in the Pre-Season periods. It was observed that most training sessions and games were classified in ACWR ranges "low to moderate" and "moderate to high". Consequently, most injuries also occurred when athletes had ACWR values within these categories
