A fitness pulling device

technical field

The invention relates to the field of sports equipment, in particular to a fitness pulling device.

Background technique

Stretching training, as an important part of flexibility training, has been paid attention to and used by more and more sports teams, and has played a unique role. Specifically, stretching is an important means for athletes to prepare for strenuous exercise and to improve their flexibility. From the point of view of system and development, it is also an important link to prevent athletes from concomitant sports injuries and finally release the maximum energy, thereby improving sports performance. For example, swimmers can increase the stroke range and water efficiency by increasing the range of movement of the shoulder straps. Therefore, in many scientific training modes, stretching training has long been used as an important part of training and treatment and rehabilitation. It can reduce muscle viscosity, reduce internal energy consumption during exercise, and increase muscle contraction speed and strength.

At the same time, in many sports, the middle deltoid muscle of the upper limbs is required to cooperate, such as various track and field events, ball games, etc., so stretching the middle deltoid is a necessary requirement for many sports. However, in the stretching training in our country, although the majority of coaches and athletes have mastered the muscles, principles of action, specific methods and precautions of stretching very well. However, due to the lack of experienced assistants, many stretching exercises cannot be used in actual training, which restricts the effect of stretching training for athletes. This is mainly because, in stretching training, stretching mainly includes dynamic stretching, active stretching and passive stretching. Because passive stretching means that the stretcher's limbs relax without participating in the exertion of force, it can achieve better relaxation effect on the stretched muscles, obtain greater joint mobility, and effectively reduce muscle soreness and fatigue reactions after exercise. However, since this stretching method is commonly used by physical coaches or rehabilitation physiotherapists to perform stretching for athletes, it is rare for athletes to use auxiliary tools such as stretching belts to stretch themselves passively. The operator must master the necessary human anatomy and biomechanics, and have a wealth of experience, in order to effectively and safely implement passive stretching. If the assistant lacks ability or cooperates insufficiently, it is easy to cause muscle damage and the loss outweighs the gain. In view of the fact that the level of support personnel in most of our training teams is difficult to meet the above requirements, and the number cannot meet the requirements for pulling the gods for each athlete, resulting in the vast majority of athletes in the training team. Better stretching training is not conducive to sports recovery and performance improvement.

Contents of the invention

The purpose of the present invention is to provide a fitness pulling device, which can complete the passive stretching training of the middle deltoid muscle by itself with the assistance of the device, so that the muscles can achieve a better stretching effect in a relaxed state, thereby obtaining a larger joint range of motion and effective recovery, which can meet the requirements of most sports training programs.
