ABSTRACT
This study examined the velocity, acceleration, ground reaction, stopping, and take-off forces, during running in a hundred meter event. An electronic telemetry system was designed and constructed for kinematic investigations, while videography was used to analyze each stride kinetic characteristics. During the constant speed, the ground reaction force and also stopping and takeoff force, mean energy and power consumption in each stride were also estimated. The performance criterion measure was time to each 10m. We have used Microsoft Excel for tracing the variation of velocity and acceleration of each subject. Three male sprinters (top national team) volunteered as subjects for the study. The sprinter`s record was 10.8 second in 100 meter run. The study demonstrate how the velocity increases widely at the beginning, the remains constant for sometime then decreases, when the runner reaches the end of the run. On the contrary, the acceleration is, maximum, just at the take-off, then decrease to zero when the sprinter reaches to his maximum velocity, then decelerates arriving to the end of run. The results on force measurements showed that the sprinter with larger strides presents larger ground reaction, stopping, and take-off forces which agree well with what the other researchers have obtained.
