| ObjectiveKinesio taping application has been widely used in the field of exercise and rehabilitation.A large number of studies have shown that kinesio taping has a good efficacy in improving soft tissue pain,swelling,and enhancing the proprioceptive feeling of damaged joints,but the effects have not been confirmed in exercise practice.The purpose of this study was to investigate the effects of different kinesio taping application on skeletal muscles,and to perform multi-factor and multi-level analysis on the optimization of kinesio taping application,and to provide a theoretical basis for the effective use of kinesio taping.Furthermore,to explore the prevention and treatment efficacy of kinesio taping on delayed onset muscle soreness,and to find new ideas and methods for the prevention and treatment of delayed onset muscle soreness(DOMS).MethodsIn the first part,40 healthy young male students,with the right leg quadriceps femoris as the study site.According to the difference of kinesio taping application,this study will be divided into 16 groups.kinesio taping was divided into two shapes(I shape and Y shape),two directions(facilitatory and inhibitory taping),and three tensions(10%,50% and 80%).The test was divided into four rounds.The subjects in first round was randomly divided into 4 groups of 10 each,each of which took a treatment factor for testing.After a 1-week washout period,the testing round was performed in a similar fashion.The isokinetic test system was used for index testing.The test conditions included maximum voluntary isometric contraction(MVIC)tests,5 times in angular velocity 60°/s and 120°/s of isometric concentric contraction respectively,and 25 times 180°/s,rest 5 minutes among the tests.The test indicators are isometric peak torque(PT),average peak torque(APT),average peak power(APP),and average work(ATW).In the second part,40 healthy young male students,with right quadriceps femoris as the study site,were divided into 5 groups according to different intervention methods,including the hot pack group(HG),the placebo group(PG),the control group(CG),the post-modeling kinesio taping group(AG),and the kinesio taping group(BG group)both before and after modeling were used.The latter two groups used the I shape,10% tension and inhibitory banding method.Participants performed 15 full-squat leapfrog and 30 half squatting-jump in weight(10kg)to induce DOMS in quadriceps femoris,10 groups,rest 2min between groups,leapfrog and weighted jump interval 2min,total exercise time 50~60min.The baseline value was measured 1 day before the subjects was modeled,and then measured immediately after the modeling,24 h,48h,72 h,and 96 h.The test indexes were visual analogue scale(VAS),six grade pain score,muscular tenderness threshold,passive sensation of motion in the knee joint,maximum isometric peak torque,and electromyography.Blood parameters include creatine kinase(CK),lactate dehydrogenase(LDH),cortisol(Cor),interleukin-6(IL-6),substance P(SP),?-endorphin(?-EP)and blood lactic acid(BLD).The test time of blood parameters does not include 96 h.Results1.The effect of

shape,direction,or pulling force,kinesio taping shapes have an effect on muscle strength,power,and work.Y-shaped stickers are better than I-shaped stickers,and Y-shaped stickers can increase muscle strength.The direction or pulling force of kinesio taping has no effect on isokinetic muscle strength,power,and work performance at different angular velocities.2.When kinesio taping is considered in the combined effect of shape,direction,and pulling force,the direction and pulling force in kinesio taping have interaction effect at 180°/s isokinetic movement,and muscle sticking is performed under centrifugal direction at 10% tension state.The optimal effect is the most obvious effect on muscle strength.3.Kinesio taping can reduce the degree of pain of DOMS caused by a large-intensity eccentric exercise,to reduce tissue swelling,to accelerate the recovery of muscle strength,and shorten the recovery of body after DOMS.4.Kinesio taping can improve the level of blood CK after DOMS,and accelerate the recovery of Cor and IL-6.Kinesio taping promote the repair of micro-injury,reduce the stress response and reduce the degree of inflammation.Kinesio taping had no effect on the change of serum SP and ?-EP,and pain-reducing pathways of DOMS did not appear to be related to the change of blood SP.5.The effect of kinesio taping on DOMS was somewhat different at use of different time points.The effect of kinesio taping before exercise was better than that after exercise. |
