摘要Muscle strength training can effectively reduce muscle atrophy,activate muscle tissue and promote muscle strength recov-ery and growth.Based on our previous research,we developed four muscle strength training strategies by further imitating the clinical muscle strength training methods,namely,Isokinetic centriPetal-centriPetal Exercise(IPPE),Isokinetic cen-triPetal-centriFuge exercise(IPFE),Isokinetic centriFuge-centriPetal Exercise(IFPE)and Isokinetic centriFuge-centriFuge Exercise(IFFE).To quantitatively evaluate the performance of the developed strategies,experiments were carried out with elbow and knee joints as examples,and muscle Endurance Ratio(ER),Flexion and Extension torque ratio(F/E)and the degree of muscle activation were extracted and calculated based on angle/torque and Surface ElectroMyoGraphy(sEMG)signals.Experimental results showed that the ER value of IFFE was significantly reduced compared with IPPE,while the F/E value of IFPE was significantly increased;this suggests that muscle centrifugation corresponds to higher training intensity;In addition,flexor and extensor muscle groups showed different levels of muscle activation in different train-ing strategies.The results reveal that combining different muscle movement characteristics,isokinetic exercise can exert special muscle strength training effects.The study can lay the foundation for exploring subject-specific adaptive muscle strength training strategies to better adapt to different levels of muscle strength.
