Bear chubby winter sports fitness benefits
Sports fitness has a good effect on blood pressure regulation, can significantly improve the blood and plasma viscosity, change the autonomic nerve excitability, make the blood vessel permeability increases, play the role of blood. At the same time, through the movement, enhancing cardiac vagal tone, and cardiac sympathetic tone in the relative ease, rhythm slowed down, so that the burden on the heart loss, heart oxygen consumption greatly reduced, so as to avoid the occurrence of cardiovascular disease. Often take part in physical exercise of men, strengthen the diaphragm on activities of amplitude, increase the suction in the pleural cavity negative pressure, and help improve circulation of heart and lung, and the amount of alveolar ventilation and gas exchange. Reducing the consumption of oxygen, reducing the energy consumption of unit time respiratory movement, to meet the needs of the body of oxygen. To improve the function of the gastrointestinal tract, the digestive system is under the direct control of the autonomic nervous system to carry out the physiological activities of the. Movement of the transversus abdominis activity amplitude gradually increased, artificially change the exciting strength of sympathetic and parasympathetic nervous system, thus regulating the function of the digestive system; at the same time, can increase saliva secretion, increase appetite, stool, conducive to the prevention and treatment of gastrointestinal diseases. The body’s blood lipids mainly cholesterol, triglycerides and phospholipids, etc.. High blood fat, easy to cause the male body arteriosclerosis, through exercise, can improve the physical metabolism, so that cholesterol, triglycerides are reduced, the prevention and treatment of atherosclerosis has a positive significance. Regular sports men, can produce a virtuous cycle, that is, the more the better, the better the body, the better the more love practice. So the mood is high, the spirit is happy, so as to produce benign stimulation and regulation of the cerebral cortex. After years of experiments show that exercise can increase the excitability of the vagus nerve, the excitability of the sympathetic nerve decreased, so as to improve the function of the nervous system.
