The purpose of the study was to determine the effects of fatigue on the impact forces and sagittal plane kinematics of the lower extremities in a drop landing task.
15 male collegiate athletes were recruited.
Five successful trials of a drop landing task were obtained during prefatigue and postfatigue in two fatigue protocols (constant speed running fatigue protocol [R-FP] and shuttle running + vertical jumping fatigue protocol [SV-FP]).
Duration time, maximal heart rate, and RPE of each protocol were measured separately.
Kinematic measures of the hip, knee, and ankle joints at different times coupled with peak impact force and loading rate were acquired.
Our results showed a more flexed landing posture due to an increase in hip and knee flexion angles in the postfatigue condition.
However, no differences in peak impact force and loading rate were found between pre- and postfatigue conditions.
The changes were similar between protocols, but the SV-FP showed a significantly shorter exercise duration time than the R-FP.
Fatigued athletes in this study demonstrated altered motor control strategies during a drop landing task, which may be an intentional or unintentional protective strategy for preventing themselves from potential ACL injury.
