Effects of Two Fatigue Protocols on Impact Forces and Lower Extremity Kinematics during Drop Landings: Implications for Noncontact Anterior Cruciate Ligament Injury

Table 3

Comparison of the joint angle and angular velocity of lower extremities in the sagittal plane during landings between pre- and postfatigue conditions within different fatigue-induced protocols (R-FP and SV-FP; ).
