In what ways does exercise promote health?

Promoting effect on cardiovascular system: Moderate exercise can thicken myocardial fibers, thicken heart wall, increase heart weight and volume, have strong myocardial contractility, and obviously reduce myocardial oxygen consumption, which has high myocardial oxygen consumption efficiency and energy-saving ability. Proper exercise accelerates calcium uptake and release, promotes myocardial contraction and relaxation, and increases stroke output.

Promoting effect on respiratory system: Moderate exercise can increase the elasticity of lung tissue and enhance the strength and endurance of respiratory muscles.

Promoting effect on nervous system: Proper exercise can promote the growth and development of the system, increase the weight and cortical thickness of the brain, and increase the cortical area on the surface of the brain. Accelerating the metabolism of brain cells has a good effect on improving the function, working efficiency and protecting the function of brain cells.

Promoting effect on exercise system: Moderate exercise can increase bone density, make bones thicker, make bone mutation at muscle attachment bigger, and make bone trabecular arrangement more regular.

Promoting the immune system: Moderate exercise is the physiological adaptation of the body to exercise stress, which is manifested in the enhancement of immune function, the difficulty of catching a cold and the enhancement of antiviral ability.

Promoting effect on digestive system: moderate exercise can strengthen gastrointestinal peristalsis, improve blood circulation, increase the secretion of digestive juice and accelerate the transformation and absorption of nutrients.
