| Exercise-induced muscle fatigue is the inevitable physiological phenomenon of sports training,it will affect the athlete's athletic performance and sports enthusiasts exercise fitness continuity,not to deal with,will increase the risk of sports injuries,fatigue can also be "fatigue" caused Physical organ disease,endangering health.At present,the study of the method of elimination of sports fatigue is the focus of sports research.Health Qigong Yi Jing Jin is China's traditional sports,spread for thousands of years,has been loved by the broad masses of the people.With the deepening of scientific research,found that Yi Jin Jing has significant effectin promoting physical and mental health.In this paper,20 athletes of Wuhan Institute of Physical Education are selected,they choose Health Qigong·Yi Jin Jingas elective course,as the research object.This study is based on literature,expert interviews,mathematical statistics,experimental method to explore the role of Yi Jing Jin by relieving exercise fatigue.First,20 subjects were randomly divided into control group and Yijinjing intervention group.the subjects were tested for blood lactic acid,subjective fatigue sensation,knee joint peak torque,knee joint body sensation before exercise,immediately after exercise and after the recovery.Then we will analyze the test data.Research result:1.The blood lactic acid concentration of the two groups was significantly higher than that of the control group(P<0.01).Compared with the control group,the blood of the rats in the control group was significantly higher than that in theintervention group(P<0.05).2.Compared with before exercise,the subjective fatigue sensation grade of the two groups was significantly increased(P<0.01).Compared with the control group,(P<0.01).3.There was a significant difference between the two groups before and after exercise(P<0.01).After the recovery,the body weight of the two groups was significantly lower than that of the control group(P<0.01).There was no significant difference between the two groups after the recovery between the two groups.4.After the exercise program,the absolute error of the knee proprioceptionincreased significantly,after the intervention of Health Qigong·Yi Jing Jin has been smaller.Compared with control group,Yi Jing Jin group in the passive position sense significantly reduced,and the change of the active position is not obvious.Conclusion:1.after exercise program,the blood lactate concentration increased significantly,intervention of Health Qigong·Yi Jin Jingcan effectively reduce the blood lactate concentration;2.Health Qigong·Yi Jin Jing can effectively reduce the subjective fatigue sensation(RPE);3.compared with the control group,Health Qigong·Yi Jing Jin increased knee flexion peak torque is not significant,but fatigue after the knee flexion peak torque reduction has a certain recovery;4.After the exercise program,the absolute error of the knee proprioception increasedsignificantly,after the intervention of Health Qigong·Yi Jing Jin has been smaller,the error of the passive position is significantly smaller,and the change of the active position sense is not obvious.;5,Health qigong·Yi Jin Jing can effectively relieve exercise fatigue,promote the rapid recovery of the body. |
