| Research Abstract |
In this study, the connection between the center of gravity and the ball of the foot seen in alternating one-legged jumping was modeled as an in verted pendulum system. And, spring-like behavior of the leg and inverted pendulum move ment were compared by superiority or inferiority of the sprinting ability. The subjects with superior sprinting ability showed the following results.(1) The leg demonstrate in a shorter duration.(2) The spring index of leg(stiffness) was greater.(3) The range of the inverted pendulum was narrower, and(4) the angular velocity of the inver ted pendulum was greater.
