Abstract Summary
The purpose of this study was to investigate the changes in the knee joint mechanics in the frontal plane induced by two typical exercise-induced fatigue protocols. Fifteen trained male athletes were recruited. Frontal plane knee joint kinematics and ground reaction forces were recorded. No significant differences were observed in the PKM1, PKM2, PKM3 and θmax between the pre- and post- fatigue tests (p > 0.05) in both R-FP and SJ-FP conditions. Only the initial knee joint angular velocity significantly increased after fatigue in R-FP. Current preliminary findings indicated that no differences were observed for knee joint mechanics during landings in the frontal plane after fatigue, regardless of fatigue protocols. Further studies are necessary to establish the relationship between motor control strategies of knee joint and the risk for ACL injuries with more exercise-induced fatigue protocols and target manoeuvres, e.g., cutting.
