Exercise aid

Technical Field

The invention relates to the field of sports equipment and rehabilitation equipment, in particular to a sports assistor.

Background

Chronic lumbago is a common pain, and according to statistics, the number of outpatients of lumbago in hospitals is second only to the main cause of cold, and about 80% of adults have experienced lumbago. Lumbago is a disease which has great influence on human health and daily life. In a large survey, more than one-fourth of adults report excessive lumbago in the past three months, affecting their work and life, and data indicate that lumbago is a major cause of miswork.

Most of lumbago is caused by muscle inflammation caused by the long-term uncoordinated state of the waist muscles due to cumulative injuries in life and work. The effect of eliminating lumbago is difficult to achieve by the existing operations and medicines because the damage of soft tissues of the waist generates lumbago, namely most lumbago is related to the problems of normal anatomical structures (spine, muscle, intervertebral disc, nerve and the like) of the lumbar vertebra, such as lumbar spondylolisthesis or lumbar instability. If the supporting force of skeletal muscles to lumbar vertebrae cannot be enhanced, lumbago is difficult to eliminate, the fundamental problem cannot be solved by the short-time action of analgesic drugs, and bed rest can only be temporarily relieved, so that the lumbar vertebrae is easy to relapse in the later period. The waist and back muscle groups can be strengthened through the exercise of the waist and back muscles, so that the stable supporting force to the lumbar is increased, the compression of a human body to the lumbar, intervertebral discs and nerves is relieved, and the chronic lumbago is prevented or relieved.

At present, the strengthening of the waist and back muscles is mainly completed through exercise, and a patient needs to do a large amount of exercises according to requirements to achieve a certain curative effect, wherein related exercise assistors or rehabilitation equipment are often used.
