The present study was undertaken for the purpose of clarifying the difference of value between the right limb the take off and the left limb the take off in the Hop Step Jump. The subjects were 120 technical college students aged 16, they were all healthy ordinary males. The results of the measurment were as follows; 1. Difference of the value between the right limb the take off and the left limb the take off in the Hop Step Jump was smaller than that of the Running Broad Jump. 2. The pass curve of the knee joint and the ankle joint of the swing up leg on Hop, natural swing up limb was longer than that of the other side limb. 3. The natural arm action is reflex and parallels the action of the legs, this movement being similar to actual walking. And arm movements are synchronized with the movements of the legs in natural jumping style. 4. Reliable correlation was found between the Hop Step Jump record and the 50 meter Dash, the Running Broad Jump record. And it was assumed that the Hop Step Jump record was closely related to the coordination in the total physical fitness.
