Description

Small-size tensile chair convenient to remove

Technical Field

The utility model relates to the technical field of sports equipment, in particular to a small stretching chair convenient to move.

Background

The stretching movement is a body-building method, and can lead the coordination between ligament muscles and joints to be softer, reduce the possibility of injury, and the stretching can be divided into two types, namely active stretching and passive stretching according to the fact that whether external force is used or not.

Active stretching, i.e., without the aid of external forces, the muscles (groups) actively stretch, e.g., lifting one leg to knee height in a standing position, stretching the popliteal muscle. Passive stretching is to assist us in muscle stretching by external forces, which may be gravity, a fitness elastic cord, or assistance from friends, such as stretching the hip and leg muscles in the supine position using elastic bands.

Active stretching is less compliant (influenced by external forces) than passive stretching, so that the active stretching efficiency is higher in terms of improving flexibility, but if external forces are not used, the range of active stretching is extremely limited because active stretching is subject to muscle force, such as when people lift the supine thigh, people with weak popliteal muscles can hardly lift the leg any more. While long-term passive stretching, while less efficient, also helps to improve joint flexibility. In a twelve week experiment, researchers found that three minutes of passive stretching of the gluteus flexor muscle daily improved the muscle stiffness condition.

Equipment used in passive stretching, such as body-building elastic ropes, is limited in general effect, the limbs cannot be stretched in a large range, the help of friends or families is often needed for stretching the limbs in a large range, and the equipment is difficult to independently stretch, so that a small stretching chair convenient to move is provided.
