Table Tennis Forehand Loop Drive Ground On The Soles Of The Feet Of The Supporting Force And Gravitv Transfer Analysis

This paper uses the Swiss Kistler force platform and constant speed cameras on the Beijing Sport University’s excellent two athletes and two the following players were in the pull loop of ground on the soles of the feet of the support force measurement and analysis. In view of the different level athletes, grouping test. In the use of force platform testing ground for athletes foot support force at the same time, will also be subjects of the technology action process of constant speed camera. For each of the subjects were tested individually, and through EXCEL software on measured data are described and analyzed. Through the test bench test, the data packet is compared, and the action cycle divided the backswing and follow through swing phase, phase and the reduction phase. While on the ground supporting capacity, from subjects around the foot, left and right direction and vertical direction and direction of these aspects of two different levels of subjects were described analyzed. And from the support force data to infer the subjects in the action cycle in various stages of body weight transfer case, and according to the ground on the soles of the feet of the support force peak and trough values appear to determine the subjects in each group at each of the stages of the time and the cycle time ratio. The purpose is to the two level of the practice in the pull loop ground on the soles of the feet support vaLue carries on the contrast analysis, find the two at each of the stages of dissimilarity, and their existing problems, in order to send now exercises in the loop technique defects, correct its problems. In this paper, the backswing stage through the ground support force value reflect, the following two in the continuous attack pull loop of the interface between the upper full backswing, the starting time of plantar pressure value fully shows the following two at last after reduction is not sufficient, in various stages of link articulation is not too good. Ground on the soles of the feet support force at each of the stages of change curve also shows the following two subjects in the action cycle of the soles of the feet on the ground of the ground is not continuous, low efficiency will affect the ball when the force caused by the poor quality of batting.
