What are some sports tips?

As the saying goes, life lies in movement. Everyone knows the principle, but few people actually take the time to exercise. Having said that, people generally have a lot of pressure in life. They are so exhausted from working so hard to make money that they don’t have the time or energy to exercise. In fact, this is a misunderstanding of exercise. Exercise can be done in just a few minutes and can be done at home. Here are some common knowledge about exercise.

1. Do not drink a lot of water during and after strenuous exercise

During strenuous exercise, salt in the body is excreted along with a large amount of sweat. Drinking too much water will reduce the osmotic pressure of the blood, disrupt the body's water and salt metabolism balance, affect the body's normal physiological functions, and even cause muscle spasms. When exercising, you need to increase your heart rate and breathing rate to increase blood and oxygen to meet the needs of exercise. Drinking a lot of water will cause the stomach to swell and fill, hinder diaphragm activity, and affect breathing; the blood circulation rate increases, which increases the burden on the heart, which is not only not conducive to exercise, but also can damage the heart.

In addition, drinking a lot of water can reduce the concentration of gastric acid and affect food digestion. Drinking water after long-term and extensive exercise can easily cause stomach problems.

2. Do not exercise after eating

After a meal, more blood needs to flow to the gastrointestinal tract to help digest food and absorb nutrients. If you exercise at this time, blood will flow to the limbs, hindering gastrointestinal digestion, which will lead to disease over time. The blood pressure of weak people will also drop after a meal, which is called postprandial hypotension, and they are prone to falling when going out. Long-term post-meal exercise can easily lead to appendicitis. Do not engage in sports such as swimming after drinking.

3. Exercising in inappropriate locations can cause harm

Since the basic function of exercise is to take in a large amount of fresh oxygen from the outside through breathing to meet health needs, you must choose a good location before exercising. Flat and open places with fresh air, such as parks, river beaches, and stadiums are the best.

4. Don’t exercise when you are in a bad mood

Exercise is not only a physical exercise, but also a mental exercise. When you are angry or sad, don't go to the playground to vent. Sports medicine experts explain that human emotions directly affect the body's physiological functions. Emotional changes originate deep in the brain and spread throughout the body, leaving traces on the heart and other organs. These traces will affect the health of the body's functions.

5. Choose the best amount of exercise

There are many methods to choose the optimal amount of exercise: for example, index assessment method, heart rate assessment method, Cooper assessment method, Fix assessment method, fatigue assessment method, simple assessment method, stage assessment method and so on. Since each person's actual situation varies greatly, the resting heart rate varies by 15-30% or even more, so the best amount of exercise should be chosen based on your age, gender, occupational characteristics, physical condition, health level, sports foundation, living environment, purpose and tasks, etc.

6. Benefits of finishing exercise

Cooling-off activities refer to a series of relaxation exercises and recovery methods such as post-exercise massage used after physical exercise, with the aim of eliminating fatigue, restoring physical fitness and improving exercise effects.

Cooling-down activities can relax tense muscles. During exercise, a large number of muscle capillaries open and the muscles are highly tense. If you stop moving immediately after strenuous exercise, the blood accumulated in the muscles will not be able to flow back to the heart in time, causing muscles to become stiff and fatigue to be difficult to eliminate. On the contrary, doing some cool-down activities after exercise can slowly slow down the exercise, or massaging and squeezing the muscles and acupoints can allow the muscles to get full relaxation and rest.

The above is an introduction to some common sense about exercise. It can be seen that there are still some rules for exercise. It is not just about going out for a few laps when you feel like it. If you do this, it may be better not to exercise. If each of us took the time to exercise regularly, there would be a lot fewer patients in the hospitals. But ifs are true.
