Introduction: Knee kinetics and kinematics are important in anterior cruciate ligament (ACL) loading in elite basketball players who repeatedly practice jumping maneuvers such as hopping. The aim of this study was to evaluate the effect of 8 weeks of functional training on the knee flexion, reaction force, and load rate during hopping in professional basketball players.Materials and Methods: In this quasi-experimental study, 30 professional basketball players were randomly assigned into experimental and control groups (n = 15 per group). The experimental group attended the functional training program three times a week, each 40 to 50 minutes, for eight weeks. Lower extremity kinetics and kinematics were collected in the pre-test and post-test stages during the hopping movement using a force plate and motion analysis system. The data were analyzed by repeated measures analysis of variance (ANOVA) at the significance level of α = 0.05.Results: The peak vertical ground reaction forces and peak loading rate significantly decreased following eight weeks of functional training (P < 0.001 and P = 0.030, respectively). The knee flexion angle in the experimental group significantly increased after 8 weeks of training (P = 0.030).Conclusion: Based on the present findings, functional training improved the muscle recruitment strategy during the hopping movement probably through increasing the functional stability of the body. Therefore, it can be concluded that functional training may help to manage the risk factors for ACL injury, such as some biomechanical factors, during dynamic movements.
