Influence of special power loads on the performance of the main muscle groups of young powerlifters of various qualifications

Abstract

The article presents that the data obtained in the course of the study give an idea of the level of development of the strength of the main muscle groups under the influence of special loads of powerlifters of various sports qualifications. Before modern science and practice of sports training in strength sports there are many problems: the rational distribution of power loads, the development of physical qualities, the increase in the functional reserves of the body, and others that are multifaceted and are solved in a complex way using pedagogical, psychological, medical and biological criteria for their evaluation. The task of the study is to determine the recovery time of power indicators of powerlifters of various sports qualifications after a directed power load and to identify the dynamics of muscle strength development in powerlifters before and after a power load. For powerlifters, extensor muscle strength is preferred. Powerful strength exercises and static efforts when performing competitive powerlifting exercises place great demands on muscle strength and static endurance. The return to the initial data of the strength of different muscle groups of powerlifters after a directed power load is not the same. Regardless of the level of sports qualification, the muscles of the trunk have the longest recovery time. The magnitude of the load in powerlifting is largely limited by the time required to restore the predominantly neuromuscular apparatus after strenuous exercise and heavy loads. Recovery of functions after exercise is characterized by a number of significant features that determine not only the recovery process, but also the hereditary relationship with previous and subsequent muscle activity, the degree of readiness to perform repeated work. The introduction of practical recommendations on the use of power loads for powerlifters into the educational process has made it possible to significantly improve the results of the power abilities of athletes of various sports qualifications.
