FUNCTIONS OF EACH LOWER LIMB SEGMENTS DURING REBOUND JUMPING TAKEOFF
Keywords: body segments function, relative impulse, aocelerative force
AbstractThe objective of this study was to examine the functions of various leg components during takeoff in rebound jumping in terms of the relative impulse and accelerabon force of each leg component The test subjects were 23 male student athletes. The experimental attempts consisted of hnno sets of tive consecutive rebound jumps, where the subjective degree of efibrt varied among six levels, loo%, 90%, 80%, 60%, 45%, and 30%, which were applied in rand om order. The focus was on the relative jump height in the derived junp height results. The funetion of the leg mpbnents during rebund jumping was examined, and the attempts involving relative jump heights near 60%, 70%, 80%, 90%, and 100% were analyzed. The resub s W dth at during rebaund jumping takeoffs, the foot mttibuted significantly to achieving the jump height. The foot was responsible for accelerating the upper body in the initial stage of takeoff, whereas that role was taken over by the leg in the middle, and in the second half of the process, the foot once again assumed that role, irrespedrve of the relative jump height
