The Effection Of Non Steady Incremental Training On Badminton Students Knee Proprioception And Dynamic Balance

Objective:To investigate the effection of non steady incremental training on Badminton students knee proprioception and dynamic balance, to find the key point of unstable factors, to gradual application of non steady training on badminton in the project to provide theoretical basis and practical guidance.Methods:We enrolled 16 badminton special students as the participants, and divided them into the experimental group (N=8) and the control group (N=8). On the basis of normal school training, the experimental group increased 8 weeks of the system of non steady training, two times a week, 50 minutes each time, through the BOSU ball, Swiss ball and other unstable equipment for non steady training. Control group maintain normal school training. Before and after the training, the knee of the two groups of subjects were tested by 60 degrees of knee and knee stability index, and the stability index and the left and right index were also collected.Results:1.8 weeks of non stable training significantly improved the main body of the knee of badminton. The dominant side of the knee was significantly improved (P<0.05).2.8 weeks incremental non steady training can significantly enhance the dynamic balance of the superior lateral knee joint, and the total stability index of the experimental group was significantly decreased (P<0.01), and the stability index and the left and right stability index (P<0.05) were significantly decreased compared with before training.Conclusion:1.8 weeks of non steady training can effectively improve the knee function of badminton special students.2.8 weeks of incremental non steady training can enhance the dynamic balance of the knee joint of badminton.
