In accordance with the right hand rule, hip flexion, adduction, internal rotation, knee extension, and adduction are presented as positive.

^*Some athletes performed the DVJ in hip adduction (+) others in hip abduction (-). As a result the mean peak hip adduction angle was negative, and actually represents a small hip abduction angle.

^**Similar to the peak hip adduction angle, some athletes performed the DVJ in hip internal rotation (+) some in hip external rotation (-). As a result the mean peak hip internal rotation angle was negative, and actually represents a small hip external rotation angle.
