THE PROPERTIES OF GROUND REACTION FORCE IN STANDING HOP, RUNNING THREE STEPS HOP AND HURDLE HOP

Abstract

INTRODUCTION: Both theoretical and experimental research has shown that the effect of the jump was highly related to the vertical reaction force of foot in contact. Current research has focused on the jump as it occurs in specific sporting activities. There is an apparent lack of research on basic jumps therefore the purpose of this study was to explore the characteristic of jump performance. Through measurement and analysis of dynamic properties of some common hops used in jump training, a significant contribution will be made to the knowledge base of this subject that will benefit athletes and coaches in many different sports.
