The Kinematic Analysis of Three Step's Distance for National Elite Male and Female Triple Jumpers
摘要
The purpose of this study were to analyze 10.male and 10 female triple jumpers three Step's distance and percent, and to compare with international elite triple jumpers. Three cameras with a speed of 60 frames per second were used to film all performances in three national final competition. This study chose the best record of the means of a 14-segment and 21-point body model. The data of three competitions were provided compute. According to the result we obtained some discussions and conclusion were as follow: 1. Among these 10 male and 10 female jumpers, there are 8 jumpers of each adopt Hop-dominate technique, the other 2 jumpers of each adopt Jump-dominate technique. 2. The three Step's percent of the male Hop-dominate technique jumpers is 38.13%:27.23%:34.60% and 38.50%:26.80%:34.62% to the female jumpers. 3. The three Step's percent of the male Jump-dominate technique jumpers is 35.33%:28.44%:36.23% and 34.50%:30.20%:35.30% to the female jumpers. 4. There are marked relationships between the achievement and the Jump phase of the male jumpers as well as the Step and Jump phase distance of the female jumpers. (P＜0.05) It shows that both male and female jumpers could get higher achievement if they raise their Jump phase distance. 5. The step phase distance percent of male and female jumpers are 27.82% and 27.00%. Obviously, the distant rates are smaller than elite jumpers. It could be considered as one of the differences between ordinary and higher achievers.
