Sports excellence growth effect on the dynamics of biomechanical characteristics of karateka's impact action (kyokushin karate-do style)

The problem actuality outlined in this article is in the fact that in karate the sportsmanship level largely depends on biodynamic characteristics of karateka's impact actions. In this connection the study purpose to identify dynamics features of biomechanical (dynamic) characteristics of karateka's impact actions (Kyokushin Karate-do style) during the sportsmanship growth. To implement the experimental part of the study two training apparatus were made, allowing to explore the effectiveness of karateka's defensive and attacking actions. With these apparatus the following biomechanical (dynamic) characteristics were investigated: static power, explosive power of muscles, work capacity, maximum of explosive power and other indicators. Karate-boys took part in the research (10-12 years old - 14 boys, 13-14 years old - 16 и 17-18 years old - 12 boys). As a result, it was found, that with the growth of sportsmanship the absolute power and the athlete's ability for explosive efforts increases. Increase of absolute muscle strength provides during the shock action raise of the force pulse value of karateka's action movement by increasing its dynamic component.
