The importance of exercise.
Although regular exercise is not as important as proper nutrition, they support health, protect against disease and what more evidence, slow down the aging process. Exercise is good for men at any age, because the normal daily activity can rarely provide enough exercise. Except for those whose profession involves intensive training (professional sports, ballet and so on. N.), Any man who wants to enjoy the effect of exercise, should take special efforts for this.
Since 1962, scientists have begun one of the most famous and large-scale studies, monitoring the health of 17,000 Harvard alumni who studied there from 1916 to 1950. Many of the results are not surprising - health of smokers and people with high blood pressure was not very good, but the analysis of physical activity revealed interesting data.
At first glance, they do not have anything special. In the end, active, intelligent man, and usually better fed, and not gaining excess weight, and less drinking and smoking. All this allows him to maintain health at a higher level. However, the researchers excluded from consideration all the positive factors, focusing on the study of the use only of exercise.
Men weekly burn 2000 calories, differed markedly better health than to spend less than 500 calories. Number of cases of cardiovascular disease was less in the first 30% of cancer - by about 20%. Even accidents with fatalities and suicides among them there were fewer.
In the former members of athletic teams at Harvard, after graduation of leading a sedentary lifestyle, health indicators were no better than those who are in college and did not show any physical activity. Students, avoid contact sports while studying, but physically active later in terms of clearly won.
It turned out that the men involved in sports, better sleep. They are also less prone to stress, depression, constipation and headaches; and in addition, more confident. Exercising strengthens not only muscles but also the bones, so physically active men with age less likely to suffer from osteoporosis and muscle atrophy.
Men who regularly do exercises, blood pressure decreases. Decline in the level of cholesterol remains in question, but we do know that it does not rise. Exercises do not contribute to the dissolution of cholesterol deposits - this requires proper diet. But dealing with sports man feels less the effects of cardiovascular disease, including heart attacks. He also lower the risk of diabetes, colorectal cancer and mental disorders.
As for stress, then at the University of Southern California watched the two groups of students. In one group of students took tranquilizers, but are not involved in sports, and in the other - on the contrary. Students of the second group were calmer, among them was less mental disorders. One of the leading theories explain the anti-stress effect of exercise that people who regularly practice them in the brain increases the level of the hormone norepinephrine, acting sedative.
