What is the use of exercise? These 4 points will make you fall in love with exercise

Exercise can not only strengthen the body, but also enhance physical fitness, improve resistance, exercise muscles, reduce fatigue, enhance various physical indicators and so on. Many people don’t like exercise because they think it is tiring and troublesome, but as long as you stick to it for a long time, you will find the benefits of exercise that will make you fall in love with exercise. Today I will explain to you what benefits exercise has for the body.

1. Improve your body shape

The most basic function of exercise is to change body shape. Through fitness, you can make any part of the body (as long as it is a part with muscle tissue) larger or smaller and effectively change its shape to achieve a beautiful body shape. This process is controllable, which is also often called the weight loss and body shaping effect.

2. Exercise can extend your life

On the basis of good health, life expectancy can be extended. Studies have found that mice that exercise every day live 25% longer than similar mice that are kept in captivity. Wild rabbits can live an average of 15 years, while domestic rabbits can only live 4-5 years. A shepherd dog can live up to 27 years, while a domestic dog only lives up to 13 years. Elephants can live up to 200 years old in the wild, but elephants that are captured and raised from a young age will not live more than 100 years old. The reason why wild animals live longer than domesticated animals is mainly because they maintain frequent exercise on a regular basis. Among post office employees, those who work in the field have a longer life expectancy than those who work in offices.

3. Eliminate brain fatigue and improve learning and work efficiency

Exercise is a form of active rest because when you exercise, the nerve centers related to exercise become excited and the centers related to cultural learning enter an inhibitory state. This inhibition becomes deeper as the excitement of the motor center increases, allowing the nerve centers related to cultural learning to get a good rest and playing a protective role. Physical exercise after studying can increase the supply of oxygen and nutrients, and is also beneficial to improving brain function.

4. Exercise enhances cardiopulmonary function

For example, just talking about the heart, the heart volume of an ordinary person at rest is 60 to 80 ml, while that of an athlete can reach more than 100 ml. Therefore, the heart rate of an athlete at rest is slower and stronger than that of an ordinary person (the heart rate of an athlete at rest is about 50 beats per minute, while that of an ordinary person is about 70 to 80 beats per minute). It reflects the advantage of high cardiac function level and economical heat. Toshihiko Seko, a famous Japanese marathon runner, has won the international marathon championship three times in a row. Scientists conducted a comprehensive examination on him and found that the ratio of his heart capacity to body weight was the highest among all Japanese athletes, and his heart wall thickness and heart shape were better than those of other athletes. His maximum heart rate is about 240 beats per minute, while the average person can only reach about 180 beats per minute. It seems that Seko has installed a high-power water pump inside his lightweight body, which supports the movement of his body with powerful horsepower. This reflects the efficiency advantage of heart function during intense exercise, which is the result of years of consistent exercise and lifestyle.
