Comparative Study of the Continuous Vertical Jumping Ability of Adolescent Athletes Majoring in Different Sports

Abstract

The purpose of this study was to find the difference of lower limb explosive force of adolescent athletes in different majors by comparing continuous vertical jumping ability, include basketball, volleyball and football. All jumps were executed with the goal of attaining maximum height and no restrictions were placed on the magnitude of countermovement or contact time of ground. 30 subjects were involved in this test and performed CJb (Continuous Jump with Bent Legs). The Portable Kistler 9286AA Measuring Force Platform was used to test the vertical jump in situ. Dynamics parameters were obtained in CJb test. It was known by comparative analysis of mean of force, peak of force and gradient value of force, the force of continuous vertical jumping of volleyball athletes is maximal, and football athletes is minimal. Maximum force value of volleyball athletes is 5.99 %bw, basketball athletes is 5.22 %bw, and football athletes is 4.49 %bw. Through one-way analysis of variance, we found that the height of three majors is not significant difference.
