The Electromyography Analysis Of The Static Force Of Difficulty Movement Of Copetive Aerobics

Group B difficulty movement of competitive aerobics is the important technology in competitive aerobics action, The complete quality directly affects the score height, For primary level athletes, the static strength of competitive aerobics difficult movement difficult, The group score high difficulty action is by the fundamental difficulty action instead of single hand or increase the swivel difficulty has evolved, so master the fundamental difficulty movement is the precondition of practicing group B difficult moves, and some basic difficulty problems still remain to be resolved.This paper uses the method of literature and materials、the method of expert interviews,Analysis of the static strength of competitive aerobics difficult theoretical analysis, Mainly uses the experimental method are studied, Use of Finland telemetering electromyography(ME6000) system for eight athletes and eight ordinary athletes competitive aerobics level, At the completion of group B static strength difficulty when the electrical test, Selecting eight group of 16 muscles, the selection of three groups of more fundamental difficulty movement(Rectangular support、Cent leg support and Static control Vincent)Understand its muscle electrical characteristics and laws, The data for mathematical statistics and comparative analysis research, Thus a series of conclusions, and put forward the high quality advice to complete difficult action. Hope the paper for the scientific study of the static strength of competitive aerobics difficult moves, The special strength training for competitive aerobics athletes provide theoretical guidance and practical reference, promote the scientific nature of the training and teaching.Through in-depth study concluded that:1. Complete orthogonal support high level group, the main work is muscle rectus, standard and stable.Ordinary group of main work is triceps muscle, the rectus insufficient strength is far lower than the high level group, other muscles instead of, is a major cause of lead to make the action when instability.2. The high level group is the main power muscle rectus, assist other muscles, make the action is very stable.Group relies on the rectus and deltoid hairdo, after the rectus work less than a high level group, lack of rectus muscle strength endurance, lead to make the action when shaking and effort.3. In the static control Vincent difficulty movement, two groups of athletes left deltoid toe biggest doing work, but ordinary deltoid muscle strength is relatively high level group is poor, need triceps compensatory power.Lift a leg in the latter, the high level group glutes force strong, can lift the leg movement, the stable control after ordinary glutes strength is lower than the high level group, difficult to lift a leg stability after the completion of the action.4. Common methods of strength training, athletes in training of rectus muscles when the effect is not significant, such as static strength cannot meet the athletes training.Suggestions:1. In the training Angle support difficulty movement, should pay attention to strengthen the power of the rectus, and pay attention to the coordination on both sides of the muscle strength, avoid major muscle strength is higher than the other side muscle strength.2. Divide leg support difficulty action reflects the importance of main power muscle strength endurance, in training to strengthen the rectus, deltoid, the main work of pectoralis major muscle strength endurance training.3. The stability of the static control Vincent mainly rely on the power of the deltoid muscle, should pay attention to the deltoid muscle strength training.Common group of athletes should strengthen the glutes and its control, pay attention to the body centre of gravity is moving to the left, in keeping the balance on the basis of the parallel to the ground.4. The main work muscles should be aimed at the special strength training, improve the athlete’s muscular strength, improve the stability of the action, thus help them grasp a standard action, improve the competitive ability.
