A multifunctional leg ligament stretching device for sports dance training

technical field

The invention relates to the technical field of sports equipment, in particular to a multifunctional leg ligament stretching device for sports dance training.

Background technique

Sports dance is a sport with high exercise intensity. Its unique artistic beauty and difficult movements put forward higher requirements on the physical fitness of dancers. Physical fitness training and leg stretching are necessary for sports dancers. Indispensably, at present, the existing simple leg ligament stretching training device can improve the flexibility and flexibility of the legs, thereby helping athletes to improve their sports performance. For dancers and yoga practitioners, the stretching of the leg ligaments is also very important. At the same time, the stretching of the leg ligaments is also a physical therapy method to restore the function of the leg muscles.

Existing sports dance requires long-term training before the dancer's leg muscles and overall waist can be softened. Traditional dancers often need to use external forces to press and bend the leg ligaments during training, and the strength cannot be done by themselves. The control is easy to cause damage to the dancer's legs, and situations such as muscle soreness may occur. Therefore, there is an urgent need for a device that enables the dancer to relax the muscles of the legs during the stretching process.
