Abstract

The purpose of this study was to investigate the effect of eight weeks training with extra weight in the hands on standing long jump performance. Fifteen junior high school male students participated in the study. Vicon motion system (10 cameras, 200Hz) and two Kistler force plates (1000 Hz) were used to collect the kinematics and kinetic data of pretraining and post-training tests. The results found the jumping distance increased 18 % after extra weight training. The horizontal velocity of center of mass (CM) at takeoff, flight distance, landing distance, the CM difference at takeoff, the horizontal positive impulse and the peak horizontal ground reaction force were all significantly enhanced. It was concluded that eight weeks of extra weight in the hands jump training increased the high school male standing long jump performance.
