An important feature of muscles is that we perfectly manage our consciousness with them. This means that we control health with our consciousness through muscles. Heart, liver, kidneys and other organs and tissues – our ability to consciously and directly influence their functions is severely limited. But musculature – a huge mass of metabolically active tissue distributed throughout the body – affects almost everything in our body.
For example, the muscles are able to quickly absorb excess glucose in the blood, thereby increasing the sensitivity of tissues to insulin and reducing the risk of developing type 2 diabetes.
Also, the musculature is the most powerful consumer of oxygen, therefore, its development is accompanied by an increase in the heart’s tolerance to oxygen starvation and, as a consequence, a decrease in the risk of heart attack. In physically active men, muscles bind large amounts of free testosterone, converting it into the more potent anabolic dihydrotestosterone. With a sedentary lifestyle, testosterone is mainly transformed into dehydrotestosterone in the prostate, which is necessary for its growth in adolescence, but with age it increases the risk of adenoma and cancer of this gland.
In addition, people with developed muscles recover faster after severe injuries, operations and stress. For example, a hip fracture in old age is accompanied by prolonged immobilization, which is fraught with a high risk of death within 1.8 years after injury. But in patients comparable in age with more developed muscles, bone tissue regeneration occurs faster, which allows you to get back on your feet earlier and avoid dangerous complications of a recumbent lifestyle. Thus, low physical activity and the resulting decrease in muscle mass correlates with a reduction in overall life expectancy.
