Analysis of the factors related to running time at different distances

Abstract

【Introduction】Running speed is often an advantage in athletic competitions, and running training is frequently conducted in various sports. The form during running is not always the same as that during short running; it has been reported that the acceleration phase at the start of running and the full‐speed phase afterwards are different. The purpose of this study was to analyze factors related to running time at different distances.

【Methods】The participants were 17 high school soccer players. The measurements were the 10 m time, 30 m time, knee flexion torque, knee extension torque, hamstring‐to‐quadriceps ratio (representing the ratio of flexion to extension muscle strength), and vertical jump height. Dashr‐Blue laser module was used to measure the running time, and the sensors were placed at three locations: the start position, the 10 m point, and the 30 m point. Pearson's correlation coefficient was used to analyze the relationship between the 10 m and 30 m running time and other outcomes. The significance level was set at 5%.

【Results】There was a significant negative correlation of H:Q ratio (r=-0.54, p<0.05) with the 10 m time, and a significant negative correlation of vertical jump height (r=-0.50, p<0.05) with the 30 m time. No significant correlations were found among other measurements.

【Conclusion】

The factors related to short running times differed depending on the distance. When training for instantaneous running performance, it may be necessary to set up a training program based on the running distance and requirements of the sports event.
