Differences in Kinematic Parameters of the Long Jump between Male and Female Finalists of World Championships - Berlin 2009

Abstract

In order to have successful technical analysis athletics uses modern biomechanical methods, and the obtained results are subjected to numerous analyzes. On the basis of the results of biomechanical parameters the most successful motor structure techniques of a competitor can be planned, programmed and analyzed, and based on this information projections for the top model in a given discipline can be made. Also based on these data possible gender differences between the jumpers can be analyzed, in order to possibly establish model and numerical values for both male and female population of jumpers. The survey was conducted on a sample of male and female finalists of the World Athletics Championships in Berlin in 2009 with the aim of determining the difference in the kinematic parameters that are important in achieving the score success. The sample included 16 athletes (8 female and 8 male), who participated in the finals World Championship. Using T-test module were obtained the results which established statistically significant differences between male and female athletes in eight (72%) of the analyzed kinematic parameters in favor of male jumpers. The differences were identified in the following kinematic parameters: running speed on the section run (11-6m; T=8,347) and (6-1m, T=8,031), the speed of the second step (VLCT2SB, T=8,678), the first step (VLCT1SB, T=11,463) and the horizontal speed of the rebound (HoVLCT, T=4,627) to the level of significance (p<0,001).Also were identified differences in the parameters of the length of the third step (LNGT3SB, T=2,840), the first step (LNGT1SB, T=2,270) and vertical speed of the rebound (VoVLCT, T=2,246) to the level of significance (p<0,05). Kinematic parameters (28%) of the second step length (LNGT2SB), the duration of phase contact (CONTACT) and the angle of reflection (ANGLE) have not recorded statistically significant differences between male and female finalists, which amounts to 28%.
