The effect of compound training on lactic acid buildup, certain physical abilities, and achieving a 100-meter swim in youth

Abstract

The current research aimed to identify the effect of compound training on the accumulation rate of lactic acid, certain physical abilities, and the 100-meter swimming achievement for youth. The researcher utilized the experimental approach with a two-group design (experimental and control) on a purposively selected sample of young swimmers. The training program included compound exercises (physical and skill-based) conducted both inside and outside the water. These exercises were implemented with precise regulation of training loads, intensities, and rest periods to meet the requirements of anaerobic energy systems.Statistical results revealed statistically significant differences between the pre- and post-tests, in favor of the post-test for the experimental group, in developing specific physical abilities (such as speed endurance and strength characterized by speed). The results also showed an increase in the body's physiological efficiency to tolerate and delay lactic acid accumulation, as well as an enhanced rate of its clearance after exertion. Furthermore, the findings indicated a clear positive breakthrough in reducing numerical time and improving the 100-meter swimming achievement. The researcher recommended the necessity of adopting compound training within the training curricula for short-distance swimmers, alongside the importance of regular physiological monitoring of blood lactic acid concentration to track the physical and physiological adaptations of the athletes.
