Some common sense of sports fitness, many people don’t know, share it.

1. Never drink water during exercise

There is nothing more ridiculous than this. You don’t even have to wait until you are thirsty to drink water. If you feel you are about to dehydrate, you should rehydrate immediately. Drink a glass of water before exercising in the morning.


Cells in the body rely on circulation to obtain the required energy and excrete waste. When water is deficient, the body fluids that moisturize the cells are reduced and the cells cannot move normally. Without body fluids, muscles cannot continue to work, and the heart is extremely tired. Some of the fluid lost is blood. This means that in order for the reduced blood to continue to circulate, the heart has to beat several times.

2. Eating sugar before exercise can increase energy levels

Taking sugar before a game or exercise is more harmful. Even things like honey and lemon juice can have adverse effects. Physiological studies have found that sugars cause insulin response. As a result, the sugar in the body is driven into the storage organ.

The need to eat sugar to replenish the exhausted energy can only take an hour and a half after a continuous exercise such as a marathon, golf or tennis match. Excess sugar will not produce additional energy.

3. Ban certain foods before exercise

Numerous tests performed at the University of California, Los Angeles Human Movement Lab have proven that the type of food people eat is irrelevant to exercise or health. We collected materials about this, select foods that were fasted, and gave them to university athletes for free. Difficult to digest, gas-producing, seasoning-everything. No matter in the sports field or in the laboratory, neither the athletes nor the researchers found any strange phenomenon, let alone any athlete fell ill from eating “forbidden” food.

4. Don’t eat before swimming

How this statement came about. We have no idea. There is no record or scientific evidence. Spasms rarely cause drowning. People who die from convulsions and drowning may suffer from heart disease.

The theoretical basis against eating before swimming is that doing so will introduce blood into the intestine. According to this statement, the heart will be overworked because muscles also require blood when starting exercise. In fact, once you start exercising, the blood flow to the intestines stops and then it flows to the muscles.

Exercise after eating, at most you can only feel a sharp pain in the ribs. But spasm has nothing to do with food.

5. Eating salt can prevent fatigue

Absolutely not. Eating salt is worse than not eating it.

It’s true that when you sweat a lot, muscles cramp unless you add salt. Salt will not immediately dispel people’s fatigue, but too much salt will cause nausea and vomiting.

6, more intake of protein can make people strong

Many athletes are convinced. As a result, the supplement salesman was overjoyed and encouraged them to eat openly. In fact, eating more protein is a waste of money.

The human body needs all kinds of food. Not eating a certain food is just as ridiculous as taking a supplement.

7.Sleep a few more hours before the game or when tired

People can neither save nor sleep. Sleeping for 12 hours is worse than 8 hours. Sleep longer than 8 hours and up to 9 hours does not produce energy

Bed rest can cause disorders. Beyond the maximum of 9 hours, the longer you stay in bed, the weaker the person becomes. Occasionally lying in a relaxed state on the bed, almost as leisurely as sleeping, while still getting enough recovery. I was worried that I couldn’t sleep. Instead of lying down for more than 8 hours, I might as well get out of bed and move around. When you can’t sleep, you should also relax.

8. Sweat once before the game

Sprinters want to practice their starting moves and doing some warm-up activities is not harmful. Any skill preparation that is different from sweat preparation is fine. And long-distance runners must not only do their best, but also keep cool as long as possible. We know that runners who have stayed cool for the longest time have the best results.

Prolonged preparations and perspiration can be counterproductive. One reason is that the preparatory activity has depleted the nutritional reserve; the other is that the body temperature generated has depleted the energy used for the game. This is a lesson for anyone who is beginning to adapt to training.

9. Perspiration can make people in good condition

The basic rule of exercise is to avoid sweating whenever possible. It takes energy to cool off the heat. This energy comes from the activity of sweat glands. When sweat glands use energy, the amount of work the body can do is reduced. When you are exhausted, the sweat glands stop secreting and you are at risk of heatstroke.

When struggling to exercise, there is no danger to be comfortable and cool, and no benefit to uncomfortably warm.

10. Put on a sweater after a workout

The love of this old grandmother is of course nonsense. It doesn’t make sense to wrap your body in clothes and prolong the heat. As for the saying that it will cause colds, it is conceivable that a certain part of the body, such as the neck, will become stiff, but the cold will not be caused by the temperature change. When sweating from your back after exercise, take off your sweater to help your body return to normal. I don’t feel hot anymore, and sweating is reduced. Wear a sweater to avoid cold. As long as the body does not overheat for a long time, people will feel extremely comfortable.

11, flush the cold water after the hot bath to close the pores

This is completely unnecessary. After taking a hot bath, it is good to have a cold bath, but the latter should be avoided, even if you are a masochist and happy to be tired. Being tortured is not only of little benefit, but it is life-threatening. Coldwater causes contraction of the skin and heart blood vessels. Blood vessels are not pores, and pores do not have to be “closed”.

12. Never exercise in the hot sun at noon

Noel Calder wrote in a song that only “Crazy Dogs and Brits” went out at noon in the sun. In fact, it is safest to exercise on sunny days. The sun is in the head, just a band along the hat to block the shade is enough. However, in the middle of the morning and afternoon, the body cannot be protected from direct sunlight.

13. Avoid intercourse before exercise

There is a popular belief that abstinence can reserve strength. This has no scientific basis. Athletes have all kinds of taboos. The better who can get rid of taboos, the better his performance will be. After intercourse (even on the morning of the day of the game), the athletes’ performance seems to be better. Inspired coaches encourage athletes to bring their spouses with them.

14. Women who exercise can lose their femininity

Quite the opposite. They will become charming, springy, vigorous, soft, flexible and powerful. Women who lift weights and gymnastics build their muscles strong. But because it has a thicker subcutaneous fat layer, it will not grow as long as a man, and the body can still maintain the female outline. The development of chest muscles can strengthen the lines of the breasts. Similarly, women’s main troubles-hips and thighs will become slimmer due to exercise.
