Organization of sports training for qualified long jumpers using blood enzyme activity

Understanding the unique characteristics of an athlete's body plays an important role in managing their sports training. Biochemical analysis is an accurate and effective method for determining the athlete's response to physical exertion. The purpose of the study is to individualize the training process of qualified track and field athletes specializing in long jump by adjusting the training load volume during the preparatory period based on blood enzyme activity indicators. Research methods: biochemical blood analysis, pedagogical testing, pedagogical experiment, statistical analysis of the obtained data. Research results and conclusions. A correlation has been established between the concentration of the enzyme creatine kinase in the blood and the level of physical fitness of long jumpers. The results obtained allow to conclude that monitoring the creatine kinase levels in long jumpers provides an opportunity to individualize the training process and improve physical fitness performance.
