The Effect of Regulating Training Load Using the Power Index on Developing Certain Physical Abilities and Performance in 100-Meter Youth Sprinters

Abstract

The study aimed to design a training program based on the power index and apply it to the 100-meter sprint for youth, as well as to identify the impact of such training on developing specific physical abilities and improving 100-meter sprint performance. The researchers hypothesized that there would be statistically significant differences between the pre- and post-tests of the research sample in the studied physical variables and performance , The researchers adopted the experimental approach with a one-group pre-post design, as it suited the nature of the problem. The research population was intentionally selected from 100-meter youth sprinters in Maysan Province. The sample consisted of six sprinters under the age of 20, representing 100% of the original population. The experimental group underwent a structured training program based on the power index, designed by the researchers. Key Findings: The study results demonstrated the effectiveness of power index-based training in developing the targeted physical variables, including maximum speed, explosive power, and speed strength, in addition to improving 100-meter sprint performance. The findings highlight the importance of directing training load based on power rather than focusing solely on volume or intensity.
