THE BIOMECHANICAL DIAGNOSIS OF TRIP-PUTTING TECHNIQUE

The purpose of this paper was to apply biomechanical analysis to the shot put technique of a Chinese high performance athlete. The data collected on trip-putting technique was recorded with fixed-spot method using PANASONIC DP200 Professional Camera, with a speed of 50 fields/second. The AIJIE 2D Analysis System was used to analyze the images, collect relevant kinetic data. In order to determine the cause of an unsatisfactory performance, the focus of the study was on the technique during the transition phase. During transition phase the interval between landings is too long, the distance between two feet after landing is too small. In addition, it was important to determine the main reason for an apparent loss of power in this phase
