1, the influence of coordination factors
Synergistic factors: mutual inhibition
(1) inhibition of nerve impulses-the action of dominating muscles is reversed or prevented.
(2) Relaxation of reaction force and muscle contraction.
(3) The appearance of endurance fatigue affects delicate movements.
(4) Spiritual practice-Spiritual practice can improve mental concentration and improvement.
(5) proprioception (proprioception)-the position of nervous muscles and joints.
Coordination refers to the timing of body movements, the correct, appropriate, balanced, stable and rhythmic direction and speed, and the theoretical movements of coordinated training. In different physical coordination training, it can be said to be the most difficult, because apart from genetic influence, coordination and athletes' psychological character, there are also muscle strength and endurance, mastering technical movements, the relationship between speed and speed endurance, weight balance (the relationship between muscle strength and muscle endurance), the rhythm of movements (before skilled technical movements), muscle relaxation and contraction, and even softness.
Coordinated training methods may be the following nine means: 1, various physical exercise movements that are not used; 2. Reverse action; 3, the speed of change has become accustomed to action and rhythm; To complete complex action games, creative operation modes and unaccustomed * * * interaction in mining are needed, which makes the main turn to more complex exercises; 7. Change the action space of business scope; 8. Use equipment or natural environment to do various complicated exercises; 9, signal or conditional stimulation, timely let athletes do various exercises to change the action.
The training method of frequency coordination is much higher at the grassroots level. Of course, if it is more than two meters long, the movements are still uncoordinated and the frequency should be high. It is best to have at least 10 action items, the frequency of which is 2 to 3 times that of the preparation period of one week, and each action should be practiced at least 3 to 5 times. Training prescription
Coordination arrangement, because this is the preparation period of intensive training and the middle period of exercise, it is necessary to lay a good foundation in the middle period of competition adjustment, and there is no special coordination training. Prescription arrangement, 20 items, can be operated according to the knitting items listed in the above training methods, plus coaches. 70% frequency, intensity is 3 times a week. The operation of is as follows:
1。 Vertical jump: feet together, hands bent and jumping up.
2。 Jump back and forth: the main point of the method, but jump forward
3。 Side jump: the method and essentials are the same as above, and jump left and right.
4。 Box jump: the method is the same as above, but jump to the position in the box.
5。 Turn to jump: the method is the same as above, but his hands should be balanced. After his body rotates 180 degrees, he jumps and jumps left and right.
6。 Steering jump: the method and essentials are the same as above, but jump.
7。 Step: cross the ball on the left and cross two steps.
8。 Torsion of hands and feet: stand on one foot and lift your feet with both hands in the opposite direction.
9。 Squatting legislation after supporting the platform: first stand with hands and feet, kick straight back and feet, then restore the original position and finally stand up.
This is a set of cycles. Other 10. The gyro rolls Song's left foot at 1 1, and the right hand touches 12. Swing 13 ball 8. Throw the ball standing. 14. Sit down and throw the ball 15 and run forward, then throw the ball 16. Squat and push each other. 17. Take the opponent's standing long jump, 18. Stop squatting and support the legislative ball. 19. Squat legislative ball, 20. Roll and catch up.
Of course, coordinated training can meet the requirements of speed, time and action, and better and more complicated action learning. The coach can make up ten or twenty movements, and there are about twenty or thirty events to practice.
