Özet

The aim of this study was to analyze the jumping and force parameters affecting the kinematics and sprint performance of stride length in 20, 40, 60 and 80th meters during the 100m sprint run. 14 female athletes voluntarily participated in this study (age=19.15±3.18 year, height=162.33±3.09cm, body weight=54.50±3.44kg, body fat%=8.42±3.01, 100m time=13.3±.60, training year=5.64±2.34). Anthropometric measurements, Squat Jump (SJ), Counter Movement Jump (CMJ), standing long jumping, standing three-step, standing five-step and standing ten-step jumping tests were administered to the participants. For kinematic analysis 100m sprint run was recorded by 4 cameras placed 20m apart. A 5th camera was used to determine the number of the steps during 100m run. Kinematic analysis was performed by identifying 18 anthropometric points and adding the 6 points of calibration cage to this fix point. A direct linear transformation method was employed to convert the results to a mathematical model. The best indicators of 100m running time were the speed of the center of gravity in the 80m (r=-.86; p>0.05) and the standing ten-step jumping (r=-.75; p>0.05). The speed of the center of gravity in the 20, 40 and 60 meters were correlated with standing tenstep jumping (respectively, r=.74, r=.68, r=.76; p>0.05). Standing long jumping performance associated with the 40m stride length (r=.62; p>0.05). A strong relationship was found between CMJ and 100m running time (r=-.79; p>0.05). The following regression formulas have been developed predicting 100m running time: 100m running time=17.168208-0.110204 x (CMJ); 100m running time=22.795469-0.390397 x (standing ten-step jumping).
