Description

Thigh muscle group stretching device with automatic lifting function

Technical Field

The utility model belongs to the technical field of lower limb exercise equipment, and particularly relates to a thigh muscle group stretching device with an automatic lifting function, which can be used for relieving and treating various symptoms caused by insufficient thigh muscle group stretching.

Background

In recent years, along with the importance of people on exercise and the popularization of national exercise for the whole people, various exercise activities are gradually integrated into the life of common people. As is well known, a group of stretching exercises are performed before the exercises, so that the injuries can be effectively prevented, the blood circulation can be quickened, the heart rate can be improved, and the exercise state can be quickened; it is well known that stretching after exercise can not only relieve muscle tension, prevent muscle congestion and muscle hardening, relieve muscle soreness, but also improve body-building effect.

Currently, the stretching motion methods commonly used mainly include active stretching and passive stretching. Wherein, the active stretching means that the action is kept at a specific position by means of the force of contracting muscles instead of other external forces, and the active stretching has the advantage that the flexibility of the action and the force of contracting muscles can be increased, for example, one leg standing; passive stretching refers to the use of body weight or instruments to hold the limb in a stretched position, which is a slow, relaxed stretching that also reduces nerve and muscle excitability, especially for relaxation after the end of exercise. However, when stretching the lower limb muscle group, it is difficult to stretch the anterior and lateral thigh muscle groups well due to the limitation of the bony structure, and on the contrary, stretching the medial and posterior thigh muscle groups is relatively easy, and if the stretching of the anterior and lateral thigh muscle groups is insufficient, the anterior and lateral thigh muscle groups are too tight, diseases such as patella migration and iliotibial band friction syndrome occur, and the joint movement of the lower limb can be further seriously affected. In addition, in the current passive stretching, the heights of the used instruments (such as steps and horizontal bars) are relatively fixed, so that automatic stretching cannot be performed when a patient who needs to stretch lower limbs or lower limb diseases after exercise passes through stretching rehabilitation training; in addition, the height of the instrument cannot be conveniently adjusted according to the requirements of users.
