At present, there are still some controversies about the causes of physical aging, such as somatic mutation theory, protein change theory and waste accumulation theory.
But we all know that aging is doomed and cannot be changed.
And effective fitness and exercise (of course, not only fitness, but also diet, good work and rest, etc. ) can make the body healthier than people who don't exercise.
Professor holman, the authority of sports medicine in the Federal Republic of Germany, used modern medical means to track a large number of men aged 60-70 for a long time, and came to the conclusion that the visceral and muscle function indexes of the elderly who insisted on endurance exercise were equivalent to the level of 20 years younger.
So the benefits of exercise to the body are mainly reflected in several aspects:
● Helps maintain a healthier cardiovascular level.
For example, reducing the level of bad cholesterol, improving the elasticity of blood vessel wall and reducing the resistance of blood in blood vessels.
Exercise is an active means to prevent and treat coronary heart disease, arteriosclerosis and hypertension.
Slow down the decline of the immune system.
Fitness people must know that the "congestion and pumping sensation" in muscle training is actually the result of blood circulation.
This will help the activity of body organs, thus reducing the decline of function.
Not to mention that fitness can keep us more muscle mass, and muscle is closely related to health.
● Reduce the decline of hormone levels.
Taking men as an example, the increase of age will reduce the testosterone level in the body, and the decrease of testosterone level will affect men's abilities, such as protein's synthesis and sexual function.
Training will help us maintain hormone levels and inhibit hormone reduction.
