Exercise training benefits for body health

There is no doubt that exercise training benefits a lot to physical fitness.

The mass and strength of men's muscles peak around the age of 30, losing 115% per decade from the age of 50 until the age of 70, when their strength is about 30% of that of 30.

About 50% of men over the age of 30 see their levels of testosterone, the important anabolic hormone in men, drop by about 1% a year. The decline in testosterone levels in men as they age can negatively affect muscle performance, muscle mass and bone density by reducing the anabolic effects of skeletal muscle.

In addition to falling testosterone levels, levels of somatotropin also decline with age. Both hGH and its main downstream protein insulin-like growth factor 1 (IGF-1) decrease with age. After age 20, HGH production decreases by about 14 percent every 10 years. hGH and IGF-1 are also significant anabolic compounds that increase cell proliferation, cell differentiation, and energy metabolism, and prevent cell apoptosis.

Exercise training is a non-drug strategy that can counteract the physiological changes that occur with age. In both men and women, exercise training has been shown benefits to increase their baseline levels of testosterone, IGF-1, SHBG, hGH, and DHEA.

Exercise training benefits for body health

The effects of exercise training on some synthetic metabolites in the body are as follows:

Testosterone - Exercise tends to lead to an increase in total testosterone from small to large. Studies have shown that both men and women experienced an increase in basal total testosterone after participating in exercise training, with effect sizes ranging from 0.19 to 3.37, ranging from small to large increases.

IGF-1- In all studies, levels of IGF-1 generally increased after exercise training, with significant increases from small to large. IGF-1 plays an important role in muscle development and insulin sensitivity. Studies have shown that the effect size of increased IGF-1 levels in both men and women after exercise training ranges from 0.27 to 1.03, with small to moderate increases.

hGH-- hGH increasing in all subjects in the study, with effects ranging from small to large. The increasing effect size of hGH in response to physical training ranged from 0.29 to 2.58, with small to very large increases.

DHEA and DheA-S - A small to large increase in DHEA and DHEA-S after training . Men also respond to DHEA-S more than women, and decrease DHEA levels are associate with decrease muscle mass and strength in men. Human studies have reported increased DHEA effect sizes ranging from 0.37 to 1.71 after training, with increases ranging from small to large.

Exercise can effectively slow down the effects of aging on the human body and is good for health. At the same time, exercise increases the body's synthetic metabolism, which is beneficial to the growth and maintenance of muscle mass and strength. For bodybuilder, anabolic supplements are used to help muscle growth and must be combined with exercise to fully function.
