| PURPOSE: Tennis is a racquet sport that competes across the net.In tennis,starting,changing direction,emergency stop,acceleration,etc.,these need athletes to have good explosiveness and sprinting ability as support,in order to play their due level in the fierce tennis game,college tennis special class students is a group based on tennis skills learning,require a certain amount of tennis competitive skills,but training resources are relatively limited,need to further improve the level of tennis competition.The post-activation enhancement effect serves as a training method to improve acute sprint performance,but the effect on specific physical performance in college students with general resistance levels is unclear.Therefore,in this study,the optimal performance period of PAP was determined by applying a 1RM load of 60%to students in the special class of college tennis class and vertical jumping results at different times.Sprint and jump training during the peak performance period of PAP to explore the impact of this training method on the physical performance of students in the tennis class.METHODS: This study employed a literature review technique to identify pertinent variables,and then employed experimental and mathematical statistical techniques to analyze and process the data before and after the intervention.Before the experiment,twenty-two students from the tennis-specific class were recruited and subjected to PAP induction.Subsequently,a group of 6 × 60% 1RM deep squat exercises were conducted,and long jump tests were conducted at various intervals prior to and after PAP induction to ascertain the most advantageous period from the long jump’s outcome.Subsequently,22 students were randomly split into experimental groups.(PAP combined with sprint jump training group)and control group(self-weight resistance combined with sprint jump training group)and trained for 8 weeks,3 times a week,during the PAP optimal performance period.Long jump,spider run and 20 m sprint run tests were performed before and after the experiment.Using Excel,a database was constructed from the data obtained,and SPSS 24.0 software was employed to perform a t-test of repeated measures variance and paired samples.RESULTS:(1)Repeated-measures ANOVA results showed peak longitudinal jump performance 3 min after PAP induction(p<0.05),and the intervention portion of this experiment performed sprint and jump training 3-12 min after PAP induction.(2)Repeated measures ANOVA to test the relationship between the 2 training methods and training time revealed significant differences between the experimental group’s 20 m performance and longitudinal jump performance at weeks 2 and 8 of training compared to the initial performance at week 8 of spider running(p<0.05).(3)Significant disparities between the experimental and control groups in the 5m and20 m,spider run,and long jump events were revealed by independent samples t-test results post-experiment,suggesting that students in tennis-specific classes with PAP combined with sprint jump training had a superior fitness performance than the control group.CONCLUSION:(1)Medium load can effectively activate the PAP effect in college students,with the best performance period of 3-12 min and the peak of vertical jump performance occurring at 3 min;(2)For college students,sprint jump training during the best performance period of PAP can better improve speed and explosive power than regular sprint jump training.(3)Training using PAP should be combined with program characteristics to design short-,medium-and long-term training programs to promote athletic performance. |
