Purpose: Volleyball has a high influence in the world, and there are many professional volleyball players and a large number of volleyball fans in all countries. China's volleyball level ranks among the top in the world, and the Chinese women's volleyball team has won many world-class volleyball championships, but the world ranking has declined in recent years for many reasons, such as athletes' personal ability, clinical performance in the game, and injuries, etc. Functional training can effectively improve the body's functionality and reduce the risk of sports injuries. Functional training can effectively improve the body's own functionality, reduce the risk of sports injuries and thus improve the body's sports performance, while non-stationary strength training, as a kind of functional training, has little research on the effects of this training on athletes, especially youth volleyball players. In this study, inspector investigated the effects of non-stationary strength training on Functional Movement Screen (FMS), Vertical Jump Height, Leg Strength and Y Balance Test of Chinese youth volleyball players from the grassroots reserve of Chinese volleyball players. METHODS: Sixty-four subjects participated in this experiment, 32 in the experimental group of which 18 were males and 14 were females and 32 in the control group of which 18 were males and 14 were females. The subjects were then subjected to 12 weeks of non-stationary strength training intervention in the experimental group and 12 weeks of conventional strength training in the control group, after which the pre-test, mid-test and post-test scores of FMS, Vertical Jump Height, Leg Strength and Y Balance Test were tested in the experimental and control groups. Repeated measures MANCOVA was performed using SPSS with subjects' YEAR, TALL and WEIGHT as covariates to explore changes in several dependent variables across groups and across gender. Since a female athlete in the control group was injured during the skill training in the middle of the experiment, the data of this athlete was excluded to ensure the accuracy of the data, and non-parametric tests and post hoc tests were utilized at a later stage to verify the accuracy of the repeated measures MANCOVA data.
