THE COMPARATIVE STUDY OF MUSCLE FORCES AND EMG PARAMETERS IN TWO FORMS OF THE STRENGTH TRAINING

摘要

Based on the facts that we can conclude: 1) There were no significant differences of the force parameters between "continuous repetition MVC" and "interval repetition MVC" in the static condition, but very significant differences in dynamic condition (p < 0.01). Thus the dynamic training form of "continuous repetition MVC" is preferable to that of "interval repetition MVC" in improving the start strength, and vice versa in improving the maximal strength and the explosive strength. 2) Despite of the difference of conditions tested, any individual's muscles were activated in similar orders corresponding to the forms of "continuous repetition MVC" and "interval repetition MVC", but even in same form of action a significant person-to-person difference was found in the muscular patterns. 3) Comparing "continuous repetition MVC" with "interval repetition MVC", there was no significant difference in the myoelectric activity level of the muscles on a whole in static condition, but a significant difference in dynamic condition (p < 0.05). The myoelectric activity level of the muscles during "interval repetition MVC" was far lower than that during "continuous repetition MVC". 4) On both forms of "continuous repetition MVC" and "interval repetition MVC", the correlation degree of EMG-force is almost medium to low. Considering all the factors that may disturb the myoelectric changes, it is not adoptable and also not scientific that the muscular force was statistically predicted from EMG parameters at present.
