Development and application of JAVA']JAVA language development test evaluation system software

In order to simplify the procedure of objective evaluation of martial arts athletes' physical fitness, and to combine the software information technology to evaluate the physical function indexes of martial arts athletes, this paper develops the "martial arts athletes' physical fitness test evaluation system" according to the physique characteristics of martial arts athletes. The research process is divided into the following three steps. First, through the literature method, expert survey method and other methods, the relevant indicators for evaluating the physique of martial arts athletes are selected. Second, according to the athlete's athletic ability, the three levels of "high-level, intermediate, junior" martial arts athletes were selected as the survey objects. The physical fitness data of the respondent was measured using a physical test instrument. Through the principal component analysis method, the sample data was analyzed, and five indicators including "hip circumference", "in situ vertical jump", "systolic pressure", "thigh circumference" and "standing position flexion" were selected as key evaluation indicators. Third, using MySQL (Relational Database Management System) database platform and JAVA technology, based on the characteristics of B/S and C/S mode, developed a "B/S, C/S" mixed mode "Martial arts athletes' physical fitness test evaluation system". The "martial arts athletes' physical fitness test evaluation system" designed in this paper can not only make a comprehensive evaluation of the physique level of martial arts athletes, but also make a general evaluation of the physique level of martial arts athletes. The software system is targeted and practical, can help the testing and management of martial arts athletes' physical fitness, and can provide reference value and promotion significance for athletes' physical fitness monitoring work.
