This kind of practice can only be a temporary pleasure, and it will have a bad influence on the body. Because strenuous exercise consumes a lot of body, the function of each part is at a relatively low level. At this time, if you drink a lot of water, it will inevitably lead to excessive burden on your heart, and drinking a lot of raw water and cold water will also stimulate your stomach and cause "stomach pain", which is not good for your health.
The correct way is to drink a small amount of water after strenuous exercise, and then increase the amount of water after a period of rest to avoid drinking raw water and cold water.
Step 2 take a bath:
Many football players take a bath immediately after practice or competition, thinking that this can not only decontaminate, but also eliminate fatigue. In fact, this practice is not scientific, because during exercise, the blood flowing to the muscles increases and the heart rate is recalled. After stopping exercise, this situation will continue for some time. If you take a hot bath at this time, the blood will not be enough to supply other important organs, such as the heart and brain, and you will feel dizzy, nausea, general weakness and even other diseases, so pay special attention. Taking a cold bath immediately after exercise does more harm than good.
Because the metabolic process of the body is strengthened during exercise, the subcutaneous blood vessels dilate and sweat a lot. Take a cold bath immediately after exercise, so that a lot of heat generated in the body can not be dissipated well, forming internal heat and external cooling, destroying the balance of the human body and easily getting sick.
The correct way is to take a rest after exercise, and it is best to wait until the pulse returns to near normal before taking a bath, preferably a warm bath.
3, the harm of smoking:
No matter whether you are a football player or not, you should not advocate smoking. Smoking is not encouraged for the sake of health. The most direct harm of smoking to the improvement of football players' competitive level is mainly manifested in reducing the typical index of athletes' aerobic endurance (general endurance)-the maximum oxygen uptake level. There are two main reasons for this result.
1
Smoking reduces lung ventilation: the maximum oxygen intake is determined by the levels of inhaled oxygen, transported oxygen and utilized oxygen, and lung ventilation is an integral part of inhaled oxygen. Because smoking will increase respiratory resistance and affect the amount of air in and out of the lungs, it is inevitable to feed it with inhaled oxygen, which will affect the maximum oxygen uptake and lead to the decline of exercise ability.
2
After smoking, oxygen absorbed by hemoglobin diffuses from alveoli to blood, and is mainly transported to various organs and tissues by combining with hemoglobin in red blood cells. Because the inhaled smoke contains carbon monoxide, its binding capacity with hemoglobin is several times stronger than that with oxygen, which will inevitably lead to a decline in the binding capacity between hemoglobin and oxygen, so the maximum intake will also be affected.
According to scientific measurement, the respiratory resistance of long-term smokers is 1 times greater than that of non-smokers. If you quit smoking 24 hours before exercise, the respiratory resistance will be reduced, and even not smoking on the same day will help restore your competitive ability. Therefore, football players had better not smoke.
