Description

Body-building pulling device

Technical Field

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

Background

Stretch training, an important component of flexibility training, has been the focus and use of increasing numbers of sports teams and has been shown to perform unique functions. Specifically, stretching is an important means to prepare the athlete before strenuous exercise, and to improve the flexibility of the athlete. From the perspective of system and development, the energy-saving sports car is also an important link for preventing sports injuries of athletes and finally releasing maximum energy, thereby improving the sports performance. For example, swimmers can increase stroke amplitude and efficiency by increasing the range of motion of the shoulder straps. Therefore, in many scientific training modes, stretching training has been used as an important part of training and therapeutic rehabilitation, and can reduce muscle viscosity, reduce internal energy consumption during exercise, and improve muscle contraction speed and strength.

Meanwhile, the middle deltoid muscle of the upper limb muscle is required to be matched in many sports, such as various track and field projects, ball projects and the like, so that the middle deltoid muscle is a necessary requirement for many sports. However, in the stretching exercise training in China, though extensive coaches and athletes have mastered the effect muscles, the action principle, the specific method and the attention points of stretching. However, due to the lack of experienced auxiliary personnel, many stretching actions cannot be applied to actual training, and the effect of stretching training of athletes is limited. This is mainly because, in stretching training, stretching mainly includes dynamic stretching, active stretching, and passive stretching. Because the passive stretching is that the limbs of the stretcher relax without participating in exerting force, the stretched muscles can obtain better relaxing effect, larger joint activity is obtained, and muscle soreness and fatigue reaction after exercise are effectively reduced. However, since such stretching methods are usually performed by physical trainers or rehabilitation physiotherapists for athletes, and it is rare that the athletes use auxiliary tools such as stretching belts to perform passive distraction by themselves, there is a need for a tacit understanding between the athletes and the people assisting stretching, and the operators must only grasp necessary human anatomy and biomechanics and have rich experience to perform passive distraction effectively and safely. If the assistor is unable to work or is not well-fitted, the muscles are easily damaged and become irreparable. In view of the fact that the levels of auxiliary staff in most training teams are difficult to meet the requirements and the number of auxiliary staff cannot meet the requirement of god pulling assistance for each athlete, the middle deltoid muscles of most athletes cannot be well stretched and trained in the training teams, and the exercise recovery and the achievement improvement are not facilitated.
