ABSTRACT:
A jumping assist system to be mounted in conjunction with each lower leg and foot of a human which will cause the imparting of additional energy during the jumping movement which will result in the individual being able to jump higher, especially in a succession of jumps, as well as having greater endurance in jumping. When the lower leg moves forwardly into the jump-ready position, a pulling force is applied from the lower leg to a tension brace which extends substantially parallel to the back of the leg to under the heel of the foot causing a forward rotational force at the ankle joint. This force will assist the individual in the jumping action. There is also a separate strap connection over the dorsum of the foot which extends along the bottom of the foot and under the heel, anchoring in the achilles area. This dorsum strap further assists in achieving an increased level of upward support and some rotational force that assists the individual in the jumping motion.
