Abstract
Objectives: Poor knee alignment during the deceleration phase of closed kinetic chain movements, such as landings, is a relevant risk factor for injuries in sports. This study assessed the knee alignment and possible associated factors in young Brazilian volleyball athletes Methods: One hundred and seventeen athletes of both genders (9-19 years old) were assessed during a drop jump for the observation of knee alignment. Chi-square test was used to describe the association between poor knee alignment and: gender, age category (≤14 years and ≥15 years), sports experience, participation in competitions, the presence of knee pain during training, and history of lower limb injury Results: Seventy percent of athletes presented poor knee alignment, which was slightly associated with a sports experience lower than one year. Conclusion: Thus, considering the high number of volleyball practitioners and its strong presence in physical education classes, preventive measures should be adopted for young volleyball athletes of both genders, especially in the sports initiation phase.
