GROUND AND KNEE JOINT REACTION FORCES DURING VARIATIONS OF PLYOMETRIC EXERCISES

Abstract

Six Division-I athletes, who routinely used piyometric exercises, performed drop jumps from 46 and 61 cm, a pike jump, tuck jump, single leg jump, counter movement jump, squat jump, and a squat jump holding dumb ells equal to 30% of 1 RM squat. GRF obtained via an AMTI force plate and video analysis of mar1 0.05). Results indicate that although peak GRF forces of landing from plyometric exercise may not differ, the KRF do possibly due to variability in landing technIques.
