Two Dimensional Kinematic Analysis of Set position to First Step with Sprinting Performance of University Athletes

Abstract

The purpose of the study was to assess the effect of kinematical selected parameters of set position to first step with sprinting performance of University athletes. Six (3 Intervarsity and 3 Intercollegiate level) athletes of Lakshmibai National Institute of Physical Education, NERC, Guwahati has been selected for this study. The mean and standard deviation (SD) of sprinters were age (20.64, 1.64), height (1.73.13 cm, 5.84), weight (61.14 kg, 3.44), arm length (62.00 cm, 3.72) and leg length (93.33 cm, 2.71). For acquiring two-dimensional kinematical data, each subject was asked to warm-up for at least 15 minutes by stretching all major muscle groups for better performing the first step during block start. Biokin-2D motion analysis system V4.5 can be used for kinematical analysis of Set position to First Step on Block Start Sprinting Performance. A standard motion driven camera i.e. handy camera of Sony Company, which frequency of the camera was 50 frame/ second. Even though this camera register photograph, at the moments from set position to first step was selected for the purpose of analysis. The photographic sequence was taken under controlled condition. The distance of the camera from the subjects was 10 mts away and was fixed at one-meter height. The alpha level of significance was set at p<0.05 for all statistical tests. The result was found that Intervarsity and Intercollege athletes in there, Trajectory Knee, Trajectory Ankle, Displacement Knee, Displacement Ankle, Linear Velocity Knee, Linear Velocity Ankle and Linear Acceleration Ankle whereas insignificant difference was found between Intervarsity and Intercollege in their Linear Acceleration Knee joint of set position to first step with sprinting performance.
