Effect of Healthy Training According to Lactic Threshold to Develop Performance Tolerance (Defensive and Offensive) and Some Functions of Blood and Liver for Young Football Players

Anaerobic threshold is barrier between oxygenic action and non-oxygenic action and work is characterized by high intensity and difficulty which causes accumulation of lactic acid in blood and muscles that exceeds ability to get rid of it, which causes pressure on work of body and its inability to continue, then decrease in performance, so researcher prepared exercises according to anaerobic threshold to increase capabilities of players to face causes of tiredness and continue to perform for long time. Research problem concerned with decrease of players performance and their inability to continue to play for a long time in competition without appearance of fatigue. Study aims to prepare drills according to anaerobic threshold to hold out pressure of high-performance level and some functional indicators of blood and liver. Researcher used empirical method that suits with nature of problem. Sample of research identified about (18) young players from Wasit football club and then divided them into two groups (empirical and control group), and he used statistical method like statistical program SPSS to treats search results (AM, standard deviation, Independent sampling codes, interrelated sampling codes). researcher concluded that exercises according to anaerobic threshold contributed to develop performance level which is reflected positively on functional indicators of blood (red and white blood cells, and cortisol), while there was no change in level of liver functions to harmonize training loads with functional abilities of players. researcher recommends dependence on results of tests as indicator and guidebook to regulate training curriculum.
