The benefits and significance of physical exercise to the body

I particularly like sports, which have many benefits to the body. I always enjoy the process of sports. Playing a basketball game with good friends can promote mutual feelings. It also allows us to find bravery and tenacity in sports and release the pressure we give ourselves in all aspects. Release all the energy during exercise, so that you can have a good mood and courage to face more difficulties. It is really a happy feeling to take a cold shower after sweating all over. The benefits of physical exercise for the body are now revealed.

When people exercise, the body's energy consumption increases and metabolic products are enhanced, that is, the force of contraction increases, the number of times increases, and the blood circulation volume increases, thus ensuring the body's need for a higher metabolic level. During activities, changes in heart function become a factor in improving heart function. Long-term scientific exercise can improve and enhance the structure and function of the heart. The average person's heart volume is around 700 ml, while that of an athlete is over 1000 ml, which is physiologically called working hypertrophy. When the heart is workingly enlarged, the heart's contractions become more powerful and the amount of blood output with each beat increases. The average person's heart beats about 70 times per minute, an athlete's is about 60 times per minute, and an excellent long-distance runner's is about 40 times per minute. Such a heart is less prone to fatigue and has greater reserve capacity, which is of course very good. Regular and scientific physical exercise can bring about favorable improvements in the structure and function of the heart.

Physical exercise can promote the body's tissue cells' ability to absorb and utilize sugar, and increase liver and muscle glycogen storage. Physical exercise can also improve the body's ability to regulate sugar metabolism. For example, under the influence of long-term physical exercise, the secretion of glucagon shows adaptation to exercise, that is, under the same intensity of exercise, the secretion of glucagon decreases, which means that the emptying of liver glycogen is delayed, thereby delaying the onset of exhaustion and increasing the time the human body can continue to exercise.

All of the above are about the benefits of physical exercise to the body. Friends who are not clear can read it carefully to see if the above content can help you. If friends who do not exercise often want to exercise after reading the above content, they must remember not to exercise excessively at one time. Because if you do not exercise often, excessive exercise all of a sudden will damage your muscles. You must do it step by step, so that the exercise can have a good effect.
