Description
Technical Field
The invention belongs to the technical field of aerobics exercises training devices, and particularly relates to an aerobics flexibility training auxiliary device.
Background
Flexibility is an important component of the fitness of the body, and refers to the range of motion of the various joints of the body and the elastic stretching capacity of ligaments, tendons, muscles, other tissues across the joints. After the flexibility is fully developed, the range of motion of human joints is obviously enlarged, and the flexibility of the joints is also enhanced. The movement is more coordinated, accurate and beautiful, and the damage of soft tissues such as joints, muscles and the like caused by the increase of the movement amplitude and the over-violent torsion can be reduced in the sports activities and daily life.
There are many training methods for flexibility, such as vertical forks: the trainees stretch their legs, push them forward and backward, erect their upper bodies and hold their hands on the ground. A transverse fork: the two legs of the trainee are stretched, the trainee can press the two legs left and right, the upper body is upright, and the trainee can hold objects or people with hands. Half split: one leg of the trainee is straightened, the rear side of the leg is grounded, the other leg is bent, the heel is attached to the hip, the inner side of the leg is grounded, the two legs are separated as far as possible, the body of the trainee is pressed down, and the hip is grounded; the upper body can do pressing and vibrating actions of bending forward and bending backward. The two legs are alternately bent and stretched, and the exercise is repeatedly carried out. Leg pressing: a positive pressure leg and a side pressure leg. The trainee is supported on one leg and the heel of the other leg is placed on an object at the same height as the waist or chest. When the legs are pressed positively, the toes are hooked, and the upper body performs pressing vibration forward and downward; when the legs are laterally pressed, the toes of the legs are buckled inwards, the toes of the legs swing outwards, the body of the legs rotates outwards, and the upper body performs pressing and vibrating actions towards the lateral lower side. When the pressure is vibrated, the upper body and the two legs are straight. Correcting kicking legs: the upper body of the trainee is straight, the left arm and the right arm are separated and straightened, and the hand becomes a fist; straight legs, hard kicking upwards with tiptoes, alternate kicking upwards with left and right legs, etc. The training methods are easy to implement, and generally have no great safety risk. The lower waist movement is not so, but the lower waist is also called "lower bridge", which is a physical exercise to develop the flexibility of the person. The lower waist action method is that two legs stand separately and have the same width with shoulders, two arms are lifted upwards, hips are raised, the upper body is tilted backwards until the head faces downwards, two palms support the ground, and the whole body is in an arch bridge shape. It is required that the limbs be straightened as much as possible and that the distance between the hands and feet be as close as possible. The action beginner can stand back to wall and then move downwards through a hand wall; can also be finished by holding the waist of the user by others. When the training is carried out, the training is assisted by using a foreign object, and when the training is carried out by using a foreign object such as a wall, although the training can slowly lower the waist, the training is inconvenient to get up after the waist is finished, the training is difficult to smoothly get up and effectively support the body after the shoulder strength of the trainer is used up, the back spine is easily damaged after the training is directly fallen down, and the training brings a great unsafe factor to the trainer. And the training with the companion, firstly, the training time of the companion is wasted, the efficiency is poor, secondly, the artificial cooperation can not only lift up the trainer, but also can possibly press the trainer.
