A Study On The Strength Of Small Upper Limb Muscles On The Frontal Overhand Serve Technique Of Volleyball Students In Physical Education Colleges

In this study the Harbin sports institute's volleyball taking students as the research object,to strengthen the upper extremity in volleyball technique teaching small muscle strength training and technology service to master degree of relationship as the research content,take the experiment method is given priority to,supplemented the literature method,experimental method,mathematical statistics and other research methods,research arm small muscles training effect influence on volleyball serve master degree.The completion of this study will further enrich the teaching means to improve the teaching effect of volleyball service technology,and explore a new way based on the theory of sports physiology for the improvement of the teaching effect of volleyball technology represented by service technology.The results show that :(1)the total number of successful service points in the experimental group is higher than that in the control group,and the number of errors in the service points is lower than that in the control group.Through the exercise to mobilize the infrequent exercise of the muscles,further strengthen the swing power,improve the number of successful service.(2)the experimental group's service landing performance is better than the control group,and the overall success rate of the landing area is significantly better than the control group.(3)through 8 weeks of upper extremity muscle group strength training,students in the experimental group scored higher than those in the control group in terms of service and landing skills,and there was a great correlation between strengthening upper extremity muscle group strength and the mastery and proficiency of serving skills,which was conducive to the learning and mastery of technical movements.In view of the process of this study,it is suggested that :(1)the fast strength training of upper limb muscles should be appropriately added in the teaching of serving technology to better improve students' serving ability.(2)the flexor and extensor muscles of the lower limbs and trunk are important conditions for maintaining balance and transferring power.Accordingly,still should strengthen the development of muscle strength of lower limbs and trunk.(3)other parts of the bodyare also important for the support and fixation of whipping movements,such as the rapid downward reverse descent of the non-hitter,which is the beginning of the upper limb power chain.
