Title

DESIGN OF AN ELECTRONIC TELEMETRY SYSTEM IN CONJUNCTION WITH A LAB-TIP AND ‎VIDEO FILMING FOR KINOMATIC, DYNAMIC STUDY OF SPRINTERS

Pages

  65-80

Abstract

 This study examined the VELOCITY, ACCELERATION, ground reaction, stopping and take-off ‎forces, energy and power consumption during running in a hundred-meter event. An ‎electronic telemetry system was designed and constructed for kinematic ‎investigations, while video graph being used to analyze kinetic characteristics for ‎each stride. During the constant speed, the ground reaction force, stopping and take-‎off forces, mean energy and power consumption in each stride were also estimated. ‎The performance criterion was time tp each 10m. We have used Microsoft Excel to ‎trace the variation of VELOCITY and ACCELERATION of each subject. Three male SPRINTERS‎ (tops of a national team) volunteered as subjects for the study. The SPRINTERS records ‎were 10.8 second in the 100-meter run. The study demonstrates how the VELOCITY ‎increases widely at the beginning, remains constant for sometime and then decreases, ‎when the runner reaches the end of the run. On the contrary, the ACCELERATION is ‎maximum just at the take-off, decreases to zero when the sprinter reaches his ‎maximum VELOCITY, decelerates to zero when the sprinter reaches his maximum ‎velocity, and 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.‏
