The effect of frequent high-intensity training in terms of the concentration of lactic acid in the blood and the development of endurance speed and achievement of 400 m runners for young men

The incredible advancements in the fields of training and physiology, along with the resulting functional responses and adaptations, aim to enhance the performance of players and help them reach their highest potential without any negative effects on their functionality or physical well-being. To minimize time wastage, the researcher employed an experimental approach, utilizing a single group with both pretest and posttest assessments. The study focused on a community of young runners participating in 400-meter races in clubs within Wasit Governorate. The community consisted of five runners. The findings indicated that frequent training has a positive impact on improving lactic acid levels, speed endurance, and overall digital achievement.
