Abstract:
Purpose of the present study was to analyse the action of running with shoes and without shoes in respect of some selected kinematic parameters. The selected kinematic parameters were (I) Stride Length (II) Stride Frequency (III) Horizontal Velocity (IV) Stride Time (V) Flight Time (VI) Contact Time (VII) Upper Body Inclination (VIII) Push Leg Inclination (IX) Swing Leg Knee Angle (X) Push Leg Knee Angle (XI) Front Arm Elbow Angle (XII) Back Arm Elbow Angle. Fifteen male athletes (sprinters) and fifteen male non-athletes were selected as subject. The movement of running was recorded by a video camera and the parameters were analyzed be freeze frame technique. Results revealed that there were statistically significant difference between running with shoe and without shoe contact time, horizontal velocity and knee angle of swing leg for Athlete group. In all the cases running with shoe provides better performance. For Non Athlete group statistically significant difference appears only in Knee Angle of Push Leg. With shoe even the Non Athlete can push the ground with higher angle. Without shoe the subjects bend the push leg more at knee, which is bad for running performance. For other selected parameters there appears no significant difference.
