Difference Between Adolescent and Collegiate Baseball Pitchers in the Kinematics and Kinetics of the Lower Limbs and Trunk During Pitching Motion

Figure 3. Phases of pitching motion. MKH; Maximal stride knee height. MAP; Maximal anterior push-off force. SFC; Stride foot contacts ground. MER; Maximum shoulder external rotation. REL; Ball release. Values measured from MHL until a particular event, expressed in time (s) or percentage of phase 1 (where 0% corresponds to the instant of maximal height of the knee of the stride leg and 100% corresponds to the instant of stride foot contact) and phase 2 (where 100% corresponds to the instant of stride foot contact and 200% corresponds to the instant of ball release).
