From The Angle Of Methods Of Electric Parsing Dial And Rubbing Method To Alleviate Biceps. Study Of Effects Of Exercise Fatigue

[Objective]Using surface electromyography, the effect of massage in alleviating muscle fatigue was objectively and quantitatively measured, and the measurements were then statistically analyzed. Analysis of surface EMG after manipulation provides objective and quantitative indicators for evaluating the effectiveness of Tuina massage treatment, and furthers understanding of the muscle-level mechanisms of Chinese Tuina massage. This research is likely to be of great significance in furthering understanding of both Tuina’s mechanism of action as well as clinical efficacy.[Methods]Test subjects were healthy male volunteers in college, and were divided as follows:rest group (Group R), plucking-channels manipulation group (Group P), and kneading manipulation group (Group K). The bicep fatigue model used60%MVC isometric tension of the biceps as a standard, the volunteers were made to isometrically contract their biceps to exhaustion, and then executed another60%MVC isometric bicep contraction, also to exhaustion, and the following data was collected:the contraction duration, MF slope, and MPF slope. MF slope includes two factors:the variation of MF frequency and the percentage of MF variation; MPF slope includes two factors:the variation of MPF frequency and the percentage of MPF variation.Then according to grouping, the test subjects were allowed to rest, received plucking method treatment or kneading method treatment, respectively. After the intervention, another60%MVC isometric bicep contraction to exhaustion was again carried out, measuring the length of contraction, MF slope, and MPF slope, and a comparison was made between contraction statistics before and after the intervention. Contraction, MF slope, and MPF slope were used for statistical analysis, to observe the difference of varying intervention methods for alleviating bicep fatigue.[Results]1. A comparison of T1&T2(the contraction duration) figures among groups The T1&T2figures among the three groups are statistically significant(p<0.05), showing that there is a significant difference before and after the intervention; T2of Group R and Group P are statistically significant(p<0.05), Group P is the longer of the two; T2of Group R and Group K are statistically significant(p<0.05), Group K is the longer of the two; T2of Group P and Group K are not statistically significant.2. A comparison of MF1&MF2(the variation of MF frequency) figures among groups The MF1&MF2figures among groups are statistically significant(p<0.05). showing that there is a significant difference before and after the intervention; MF2of Group R and Group P are statistically significant(p<0.05), Group P is the longer of the two; MF2of Group R and Group K are statistically significant(p<0.05), Group K is the longer of the two; MF2of Group P and Group K are not statistically significant.3.

A comparison of MPF%1&T MPF%2(the percentage of MPF variation) figures among groups The figures MPF%1&MPF%2among groups are statistically significant(p<0.05), showing that there is a significant difference before and after the intervention; MPF%2of Group R and Group P are statistically significant(p<0.05), Group P is the longer of the two; MPF%2of Group R and Group K are statistically significant(p<0.05), Group K is the longer of the two; MPF%2of Group Pand Group K are not statistically significant.[Conclusion]1. Based on the experiments, both the plucking-channels manipulation group (Group P), and the kneading manipulation group (Group K) have better efficacy in alleviating exercise-induced bicep fatigue than the rest group (Group R). From this, Tuina is shown to effectively alleviate exercise-induced bicep fatigue.2. In this experiment, there are no statistically significant differences between the plucking-channels manipulation group (Group P) and the kneading manipulation group (Group K), so there is no difference between plucking-channels manipulation and kneading manipulation for alleviating exercise-induced bicep fatigue.
