Background and Study Aim: There is only few reports which could give answers for combining both technical skills and strength ability with electrical control of muscle activity. The main objective of this study is knowledge about relations between bioelectric muscle activity, registered during the muscle strength activity measurement at 17 to 19 years old judo athletes and the level of their technical skills (throws). Application purpose was to define the topography of electrical activity of chosen agonists and antagonists, registered during the measurements of muscle strength, depending on technical skills of 17 to19 years old judo athletes.
Material and Methods: Age of examined 30 judo athletes: average 17.83 ±0.64 years; body weight 69.66 ±12.33kg. During the research following methods of measurements was used: electrical muscle activity EMG, muscle strength in different conditions of its realisation.
Results: Fifteen technical skills in judo (throws) have revealed their correlation with electric activity of agonist and antagonists in measuring muscle strength in three out of four strength manifestations: in isotonic strength, in power and jumping rate, and static strength. Among these: 5 belonged to leg throws; 4 to hip throws and 4 to “dedication throws” and 2 to the hand throws.
Conclusions: Value of muscle electric activity defined in the measurement of strength endurance stayed without any statistically significant correlations with technical skills. On the basis of the studies of muscle electric activity, registered during the measurement of various muscle strength manifestation and based on the practical experience, the results of above researches can be used in the process of training of young judo athletes.
