Abstract

The thesis aimed to examine the blood lactate index, which is influenced by the training loads in the 800-meter event, and to investigate the rest periods used after each physical effort, along with regulating the rest intervals between exercises based on the blood lactate index before and after each physical effort. The researcher hypothesized that there would be statistically significant differences in the lactate index results between the pre-test and post-test, as well as significant differences between the lactate index and performance. The researcher redownloaded theoretical studies related to the research topic, including rest periods, the concept of blood lactate, and the 800-meter event. The experimental method was used with a single-group design, as it suited the nature of the research. The sample consisted of six athletes from the 2014 youth athletics team, selected through purposive sampling, with three athletes included in the final sample. The training program lasted for 12 weeks, with two sessions per week, resulting in a total of 24 training sessions. Appropriate statistical treatments were applied to analyze the results, which were then presented, analyzed, and discussed. The main conclusions were: (1) a noticeable improvement in blood lactate concentration in the sample due to the regulated rest periods, and (2) improved performance as a result of the controlled rest intervals, which had a positive impact on the research sample's results. Based on these findings, the researcher recommended: (1) using regulated rest periods in short-distance training, (2) conducting similar research for older or younger age groups in the 800-meter event, and (3) conducting similar studies for different age groups in both short and long-distance events.
