Why the more exercise, the worse our physique. Timely exercise is more conducive to promoting blood circulation. Exercise can also help us get rid of fat. We should arrange the exercise time reasonably. This sport requires high physical fitness. Let's see why the more exercise, the worse physical quality and knowledge.

Why the more you exercise, the worse your physical fitness. 1 The human body is a balanced system. When our immune system is stronger than external viruses and bacteria, our bodies will not get sick. On the contrary, when the immune system is weakened for some reason, then the human body will be troubled by various germs and get sick.

The influence of exercise on the immune system is two-way.

The University of Toronto divided 65438+ people aged 09 -29 into two groups for testing. Group A takes 40-minute aerobic exercise three times a week, while Group B takes 40-minute aerobic exercise five times a week. After 12 weeks, the blood test showed that the number of immune cells in group B decreased by 33%, and there was no change in group A.

There is a technical term in medicine-window period. It refers to the low concentration of antibodies and lymphocytes in the immune system during the recovery period of 3-72 hours after intensive exercise. This greatly increases the probability of germs invading the body, so it is easier to get sick.

It's like, if you open a window for the body's defense barrier, pathogens can easily come in.

Generally speaking, you take all the energy of your body to exercise, and there is no extra energy to support the normal work of your immune system. The end result is illness.

Many people can't get a timely rest after exercise, and continue to stay up late to watch dramas and play games. B cells in the body become very weak, the immune function of the human body decreases, and the resistance of the human body also decreases.

Staying up late can be fatal to the cardiovascular system. Short-term lack of sleep will lead to abnormal vasoconstriction, elevated blood pressure and decreased glucose tolerance. Many people's sudden death is caused by staying up late for a long time.

In addition, staying up late will lead to immune dysfunction, which in turn will lead to nephritis, lupus erythematosus, rheumatoid arthritis and so on; People who often stay up late will also have neurasthenia, eye diseases, and the incidence of cancer is higher than the average person.

Therefore, whether you are losing weight or shaping, you must pay attention to the combination of work and rest during exercise to ensure adequate rest and sleep.

Why the more you exercise, the worse your physical fitness. 2. Sports misunderstanding: excessive exercise.

Everything should be controlled properly, especially exercise. Under normal circumstances, the amount of exercise a day should be controlled at two hours. Persistence is the most important thing in sports. We should keep exercising every day and should not give up halfway. However, long-term exercise will increase the pressure on muscles and bones and easily increase the chances of injury, which is actually contrary to the basic concept of exercise.

Exercise Myth 2: Take a rest immediately after exercise.

When you enter a state of exercise, your body will undergo a series of physiological changes, such as metabolism, increased vital capacity, and accelerated heartbeat, but these changes will not disappear immediately with the cessation of exercise. Therefore, if you stop exercising immediately, it will reduce blood circulation and easily lead to exercise syncope. It is suggested that you can choose to walk slowly or do stretching exercise after exercise to give your body a space to adjust.

Misunderstanding 3 of sports: if it suits others, it suits you.

Many people like to follow the trend and blindly imitate other people's exercise methods when they see that other people's exercise is effective. But the exercise suitable for everyone is actually different. You should choose exercise according to your physical condition and hobbies. If you love this sport very much, the effect of exercise will be better.

Exercise Myth 4: Exercise completely on an empty stomach.

Many people will choose to exercise on an empty stomach because they think it is faster to lose weight. As everyone knows, this is wrong. When people are on an empty stomach, their blood sugar concentration is low. Doing sports at this time consumes a lot of energy, and their blood sugar concentration will be lower. Blood sugar is the direct energy supply of the brain. When the blood sugar concentration is low, the brain will feel tired due to lack of motivation, and people will feel dizzy, weak, pale face, cold sweat and other symptoms, and even faint.

Myth 5: Do not pay attention to hydration during exercise.

Everyone feels thirsty after exercise. At this time, everyone basically knows to hydrate, but you may not know that you also need to hydrate before and during exercise. Not drinking water during exercise, especially in hot weather, can easily lead to water shortage in the body, affect metabolism, and the exercise effect is poor, which is not conducive to weight loss.
