The effect of special endurance Exercises on developing some biochemical variables among young boxing players under 18 years of age

Abstract

The research problem centered on the fact that most coaches use exercises to overcome fatigue without knowing their physiological and chemical effects, and through the researcher follow up, being one of the specialists in this game, he noticed differences in the boxer's muscle fatigue during competition and after interviewing most trainers, it became clear that there are no special tests for biochemical variables that happens to an athlete during a competition or exercise. Therefore, the researcher prepared special endurance exercises to develop some biochemical variables for young boxers under the age of 18 years. The research aims to identify the effect of special endurance training on developing some biochemical variables among young boxers under the age of 18 years. The research community was identified with the 13 young boxing players belonging to the Hilla Sports Club for the 2019 season, where the researcher used the comprehensive inventory method by selecting the research sample. The sample was divided into two groups (experimental - control) and each group had (5) players, and (3) players were selected for the pilot study. Through the researcher's review of many scientific sources and references in the field of physiology of sports training - boxing, the following variables were identified, which are: The hormone beta - endorphin, the percentage of lactic acid concentration in the blood, the enzyme lactate dehydrogenate (LDH). The researcher concluded that the special endurance exercises worked to improve the hormone endorphins, lactic acid, the enzyme lactic dehydrogenate in the research sample and the exercises prepared by the researcher reduced fatigue during competition.
