Exercise can prevent cardiovascular disease. Exercise, especially aerobic exercise, can increase the output of cardiovascular blood, enhance the contractility of myocardium, improve the whole body’s blood supply. Systemic blood vessel also has rhythm to contract and dilate in motion process, flexibility increases, arteriosclerosis decreases. Although the heart beats faster and gives the body enough blood to beat more blood per unit of time, when exercise stops, the heart beats more slowly than normal, which is good for health and longevity. In addition, exercise needs to consume energy, promote fat burning and utilization, which can avoid fat and hyperlipidemia, and reduce the risk of cardiovascular disease.
Exercise can prevent and treat diabetes. Some people say diabetes is a disease of affluence. In fact, diabetes is actually caused by lack of exercise. Studies in different countries have found that even moderate physical activity is enough to prevent 60 percent of type 2 diabetes cases. So why does lack of exercise lead to diabetes? Simply put, exercise can stimulate the secretion of insulin and accelerate the cell’s oxidation and utilization of sugar. When the muscle lacks movement to take exercise, can restrain the secretion of insulin, drop for a long time, can cause candy metabolization disorder, cause diabetic. In addition, exercise can also accelerate the oxidation of fat, thereby reducing the risk of fat. As we all know, obesity is also an important cause of diabetes, because fat is also an endocrine gland. Adipose cell, especially big adipose cell, can secrete the lipid that suppresses insulin, reduce the activity of insulin thereby, prevent a cell to make full use of candy.
Exercise can prevent osteoporosis. Osteoporosis is a common disease that threatens middle-aged and elderly people, and exercise is the most effective way to increase calcium absorption. American orthopedic experts put forward a new idea: in the pathogenesis of osteoporosis, mechanical factors (such as a lack of calcium, vitamin D, hormone) is not the main, and in the muscle mass under the control of the nervous system, including muscle) quality and strength) is to determine the bone strength (including bone mass and bone structure) of the most important factor. The person that be short of calcium participates in right amount motion to take exercise only, make skeletal bear force, improve the effect that fill calcium. Studies show that bone-related hormones, calcium and vitamin D can determine bone strength, and that exercise can affect bone strength by up to 40 percent. The theory could explain why even calcium supplements do not prevent osteopenia in people who spend too much time in hospital beds or who suffer from most forms of muscular dystrophy. The researchers believe that through exercise and exercise, bone load and muscle stretching can be strengthened and combined with the use of osteogenic drugs. It can stimulate bone formation, recover lost bones, and maintain a certain degree of bone strength. Therefore, calcium supplementation and proper weight-bearing exercise are the most effective ways to prevent osteoporosis.
Exercise can prevent cancer. Regular exercise can reduce the risk of colorectal cancer. Because sitting for a long time will inevitably lead to slow intestinal peristalsis, constipation and hangover detoxification, mainly protein, bacterial toxins and heavy metal ions and other decomposition products, stimulate the intestinal wall caused by intestinal mucosal cell mutations leading to cancer. Exercise increases intestinal motility, which helps remove these toxins in time because it reduces cancer. In addition, as defecation accelerates, toxins are reabsorbed, reducing the incidence of breast, lung and other cancers.
