Designing Specific Training and Its Effect According to the Time Duration for Monitoring Lactic Acid Concentration in the Blood and 400 Meter Running Performance for Youth

Abstract

The physiological sources indicate that there is variation in the time concentration of lactic acid in the blood, and that a sample should be taken for measurement. Given the importance of lactic acid as an indicator in training and the variation in running activities with respect to time and intensity, the significance of this study lies in determining the most appropriate time duration for monitoring blood lactic acid concentration after a 400-meter race effort during the preparation phase for youth. The research problem concludes that multiple time durations were set for monitoring lactic acid concentration, specifically 3, 5, and 7 minutes, to evaluate which duration is most appropriate. Additionally, the study examined whether there were statistically significant differences in blood lactic acid concentration after the race effort for these time intervals.

The sample consisted of a selected group of youth in the 400-meter race, with 4 athletes chosen intentionally. Statistical analysis was performed using the SPSS software. The main findings of the research showed that the optimal time for the highest blood lactic acid concentration after the 400-meter race effort was 5 minutes. The study recommends that coaches and researchers adopt the 5-minute time frame when measuring lactic acid to regulate training loads and assess training intensity, which will contribute to improving performance in the 400-meter event.
