The Relationship Of Judo Athletes Torso Support Contraction Ability And Competitive Level

Purpose:Judo is acyclic project with field Fighting. Power is the foundation of the judo athlete give play to an excellent skill and tactics. For judo athletes, The stability of the various parts of the body and motion is always under frequently and quickly alternating. Participate in the contraction of muscle is not only to the static contraction, but also in the state of static contraction force. We usually called the first to do isometric again resistance of muscle contraction for support contraction.The current research is intended to explore the relationship between support contraction and competitive of judo athletes.Methods:In order to explore the relationship between support contraction and competitive of judo athletes, used the methods of literature reference, experts interviews and videos analysis to do study.Results:1. Elite support contraction strength in trunk flexion and trunk rotation aspects were significantly higher than the general group athletes.2. Elite athlete support contractile force when the action and reaction were significantly shorter in group athletes in general.3. The two athletes muscle activation levels substantially no difference in the support phase. Contraction phase Elite Athletes muscle activation levels were significantly higher than the general group of athletes.Conclusion:1.The elite judo athletes, the higher torso maximum strength and relative maximum strength. excellent athletes torso flexion and extend, the left and right swing muscles strength size more balanced.2. The higher competitive level athletes, the ability to support the contraction is stronger, and the strength and support contraction reaction ability are more prominent, it indicates that support contraction ability is an important quality judo special the strength, should be given attention to in training.3. In judo stalemate against movement, the function of the excellent athletes and the general athletes torso muscles state has no obvious difference in support phase, but the power is in the second stage, the elite athletes mobilization rate and contraction of the muscle strength is better than the general athletes. Prompt judo athletes should pay more attention to stalemate ability of secondary power, should join in training to support the contraction ability related training.
