Rationalizing the rest between exercises and its effect in terms of the lactic acid index in achieving the effectiveness of running 800 meters for young people

Abstract

The goal study aims to identify the index of lactic acid in the blood, which is affected by the training loads for the effectiveness of 800 meters, to identify the rest used after each physical effort, and to ration the rest between exercises in terms of the index of lactic acid in the blood before and after each physical effort. The researcher assumed that there are statistically significant differences in the results of the lactic acid index between the pre and post-tests and that there are statistically significant differences between the lactic acid index and achievement. The researcher used the experimental method in the one-group method due to its suitability to the nature of the research, and the research community was determined by the players of the Missan Governorate team for the 800-meter running event for the youth category for the season 2021, whose number is (6) players. The duration of the curriculum is (12) weeks, at the rate of (2) two units per week, as the total number of units of the training curriculum is (24) units.
