A kinematic analysis of technique of sprinters at national level
Author(s): Dr. Praveen Kumar
Abstract:
The purpose of the study was to compare the selected kinematics variables of the technique of national male and female sprinters. The subjects of this study were three males and three females Inter-university athletes of Lakshmibai National Institute of Physical Education, Gwalior (M.P.). The age the subjects were between 18-25 years.
The sequence photographic technique was employed to register the sprinters technique. A motor driven, Nikon Model EM Camera was used. The subjects were photographed at 40-55 meters marks in sagittal plane. The filming Zone was 15 meters in width only moment take-off was analyzed. From the photographs, the stick figures were prepared by using joint point method and various kinematics variables were obtained. Segmentation methods were employed in order to assess the center of gravity of the body during the moment of take-off. Selected kinematics variables were Angle at Ankle Joint (sprinters), Angle at knee Joint (Supporting Leg), Angle at Ankle Joint (Swinging Leg), Angle at knee Joint (Swinging Leg), Angle at Trunk Inclination (with vertical), Push-up Angle, Height of Center of Gravity at Moment Take-off, Take-off Distance and stride length.
The data were analyzed by‘t’ test to ascertain the comparison of male and female sprinters. The results have shown the insignificant values of‘t’ ratio for all the selected kinematics variables of the study at the significance level of 0.05.
