Influence Of Block Phase Mechanics On 100-Meter Sprint Performance: A Study Of Hip Angle, Knee Angle, And First-Step Distance

Abstract

The study's goal was to determine how stride length, stride angle, and flight time related to block phase 100-meter sprint performance. Ten collegiate sprinters were chosen for this purpose from among Jammu's colleges and sports clubs.Three Y1 cameras with an f/2.8 aperture lens and a 140-degree field of view were used to record the subjects while they ran a 100-meter sprint on a synthetic track at 60 frames per second and 1080p. Each of the three cameras was positioned 0.94 meters above the ground and seven meters away from the plane of motion. One hundredth of a second was used to measure the 100-meter sprint performance. KINOVEA software was used to analyze the recorded footage in order to determine the first leg's distance from the start line (meters), hip angle (degrees), and knee angle (degrees). To determine the impact of  the first leg's distance from the start line (meters), hip angle (degrees), and knee angle (degrees) on 100-meter sprint performance, the gathered data was analyzed using Pearson product moment correlation. The level of significance was set at 0.05 in each instance. It was determined that the 100-meter sprint performance was significantly correlated with the first leg's distance from the start line, hip angle, and knee angle.
