Effects of Isokinetic Concentric Training and Simultaneous Electrical Stimulation on the Rapid Strength of Knee Flexors and Extensors
Objective:To explore the effect of isokinetic concentric training synchronous electrical stimulation on the muscle function of flexor and extensor group of knee joint and its mechanism,and to provide some reference for the application of electrical stimulation and training and other related fields.Methods:Twenty healthy adult male subjects who met the selection criteria were randomly divided into isokinetic muscle training synchronous electrical stimulation group and control group,with 10 people in each group.The two groups of subjects performed the same training program on the IsoMed2000 isokinetic muscle tester,and the experimental group was given simultaneous electrical stimulation during training.Three times a week for six weeks,the indexes of flexor and extensor muscle group maximal voluntary isometric contraction(MVIC),peak torque(PT),Work(WORK)were observed before and after training Results:After 6 weeks of training in both groups of subjects,the PT and MVIC of knee extensor muscles in both groups showed a significant increase compared to before training.There was a significant difference between the stimulation group and the control group.The PT value of the knee flexors and the work of the flexors and extensors of the two groups of subjects after training were significantly higher than before the training.There are significant differences in muscle PT.Conclusion:Isokinetic strength training can effectively increase the MVIC,PT and Work of the knee flexors and extensors,and the training effect after simultaneous 30％MVIC intensity electrical stimulation is significantly higher than that of pure isometric strength training.Isokinetic strength training and simultaneous electrical stimulation can strengthen the fast muscle fibers in skeletal muscle,which is beneficial to the development of fast muscle strength.
