| Objective: To compare Flywheel Eccentric Overload Training;FEOT and rapid expansion combined Training(Plyometric Training;PT)influence on the lower extremity sports performance of wrestling and judo students,enrich and improve the lower extremity training means and methods of combat sports,and provide reference for its physical training practice and promote scientific competitive training.Research methods: Twenty subjects were randomly assigned to experiment group 1(FEOT group,N=10)and experiment group 2(PT group,N=10)by using the research methods of literature,experiment and mathematical statistics,and received training intervention 3 times a week for 4 weeks.The influence of the two training methods before and after intervention on the athletes’ maximum strength of lower extremities,explosive power,changing direction sensitivity and short distance sprint was analyzed and compared.Research results:1)After the experiment,squat 1RM test index scores of FEOT group and PT group were improved before and after the experiment,and there was a significant difference in FEOT group before and after the experiment(P < 0.05),and the change amount of FEOT group before and after the experiment was better than that of PT group.2)After the experiment,the scores of CMJ,SJ and standing long jump in FEOT and PT groups were improved to some extent before and after the experiment,and the scores of CMJ and SJ were significantly different among groups after the experiment(P < 0.05);The centrifugal utilization ratio(EUR)and DJ reaction force index of the FEOT group were significantly different before and after the experiment(P < 0.05).The variation of the standing long jump test index of the PT group was significantly better than that of the FEOT group.3)After the experiment,the 5-0-5 and T-run test index scores of FEOT group and PT group were improved to some extent before and after the experiment.The 5-0-5 test index of FEOT group was significantly different before and after the experiment(P <0.05),and the T-run test index of PT group was significantly different before and after the experiment(P < 0.05).After the experiment,there were significant differences between the groups in T-running test index scores(P < 0.05).4)After the experiment,the scores of 10 m and 30 m test indexes in FEOT group and PT group were improved to some extent before and after the experiment,among which there was cant difference between the 10 m sprint running group and the 30 m sprint running group before and after the experiment(P > 0.05),while there was significant difference betno signifiween the 30 m sprint running group and the 30 m sprint running group before and after the experiment(P < 0.05).Conclusion and suggestion:1)After 4-week training intervention,flywheel centrifugation training can enable athletes’ lower limb muscles to continue to bear the load in the centrifugation stage,and the neuromuscular system needs to recruit more exercise units to participate in the work,so that the muscles can generate more force in the contraction stage to improve the maximum strength of lower limb,centrifugal utilization rate and direction changing ability.In the training process,the real-time feedback data can make the training load more accurate,and can better stimulate the athletes’ training enthusiasm,improve the training efficiency.2)After 4-week training intervention,rapid telescopic compound training in both vertical and horizontal directions can reduce muscle response time when athletes are doing work in centrifugal deceleration and centripetal acceleration,thus promoting the improvement of athletes’ agility and lower limb explosive power,and can make up for the problem that too much attention is paid to starting and accelerating while ignoring deceleration in previous training.3)The two different training methods,flywheel centrifuge and rapid telescopic compound,have their own emphasis.They should follow the special technical and tactical characteristics and the needs of personalized training,and select and design training programs according to different training cycles,different training objectives and tasks as well as individual differences of athletes,so as to promote the scientific training level. |
