Physical characteristics analysis of judo athletes based on multiple regression equation

Abstract

Abstract Judo is a skills-led sport, which has higher requirements on the athletes’ skills, physical ability, intelligence and psychology, but the athletes’ physical characteristics are still the basis of competitive ability. In this article, 107 male judo athletes were selected as the investigation object, their body shape indexes and some physical quality indexes were measured, the independent sample multiple regression method and T-test were applied to compare and analyze the elite and non-elite athletes, the youth and adult athletes, and the standardized typical discriminant function of athletes’ sports grade was established by stepwise discriminant analysis. Thus, we have a comprehensive understanding of the physical characteristics of the men's judo athletes and provide a reliable basis for the training and selection of basic coaches.
