plate-loaded kneeling leg curl with internal rotation
The participant was instructed to point toes toward medial side as knee flexing. This is an open-kinetic chain (OKC) exercise and medial hamstring was emphasized.
plate-loaded squat press
The subject was instructed to position his back properly against the backrest on a machine, with the feet slightly apart. He was instructed to place his feet higher on the foot plate and draw his two knees as close as possible while the knees flexed so that medial hamstring would supposedly bear more tension in the course of knee flexion. This is a closed-kinetic chain (CKC) exercise and was expected to strengthen the quadriceps and hamstring with medial hamstring emphasized.
