Abstract :

Once upon a time players of all games and sports ran barefoot. After some time players of most of the games and sports run with different shoes. The purpose of present study was to compare the responsible mechanical factors for the performance of with shoe and without shoe running. Fifteen male athletes and fifteen male non–athlete were selected as subjects. The selected mechanical parameters were (a) Stride Length (b) Stride Frequency (c) Horizontal Velocity(d) Stride Time (e) Flight Time (f) Contact Time (g) Upper Body Inclination (h) Push Leg Inclination (i) Swing Leg Knee Angle (j) Push Leg Knee Angle (k) Font Arm Elbow Angle (l) Back Arm Elbow Angle. The movement of running were recorded by 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 in contact time, Horizontal velocity and knee angle of swing leg. 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.
