Technical Field
The invention relates to a dual-purpose machine for single crawling and double running, belonging to the technical field of sports fitness equipment.
Background
Crawling, i.e. the cooperation of both arms supporting the ground and both feet, forms the action of reciprocal crawling of the limbs, which is called "return to ancestor" action. For adults, the crawling can disperse the whole weight of the spine to four limbs so as to lighten the load of each part of the body, particularly the lumbar, and restore the whole spine to a physiological state. Therefore, the medicine has better curative effect on lumbar disc herniation patients, lumbar muscle strain and various cervical, shoulder and spinal diseases. When a human body is upright, the gravity influence of blood is overcome to promote blood circulation by the heart. When a person moves upright, the lower limbs are the main moving organs, blood is distributed to the lower limbs more, and the blood supply of the heart and the organs above the heart is reduced. Compared with the prior art, the heart and the parts above the heart are reduced during crawling, so that the heart-blood circulation is facilitated, and the heart-blood circulation-promoting and heart-blood circulation-promoting device has a positive effect on preventing and treating cardiovascular diseases.
