Pay attention to these points after fitness exercise.
First, don't squat and rest: this is a very common practice. If you feel tired after exercise, you will squat down or sit down, thinking that this can save effort and rest. In fact, this is a wrong practice: if you squat and rest immediately after fitness exercise, it will hinder the blood return of lower limbs, affect blood circulation and deepen physical fatigue. In severe cases, gravity shock will occur. Therefore, after each exercise, we should adjust the breathing rhythm, walk and swing our arms, do some relaxation and adjustment activities, and promote the blood of limbs to return to the heart, so as to pay off the "oxygen debt", speed up physical recovery and eliminate fatigue.

Second, don't be greedy for cold drinks: exercise often makes people sweat, especially in summer. With the consumption of a lot of water, there is always a feeling of thirst after exercise, and water is urgently needed. Mainly young people, like to buy cold drinks to quench their thirst. But at this time, the human digestive system is still in a state of inhibition and its function is low. If you eat a lot of cold drinks for a period of time to quench your thirst, it is easy to cause gastrointestinal cramps, abdominal pain and diarrhea, and induce gastrointestinal diseases. Therefore, don't eat a lot of cold drinks immediately after exercise, you can add a small amount of boiled water or salt water.

Third, don't eat right away: during exercise, especially during strenuous exercise, the motor nerve center is in a state of high excitement. Under its influence, the parasympathetic nervous system, which manages the activities of internal organs, strengthens the inhibition of digestive system activities. At the same time, the whole body blood is redistributed during exercise, and the need for exercise organs is intensively supplied, while the supply of organs in abdominal cavity is relatively reduced. The above factors weaken gastrointestinal peristalsis and greatly reduce the secretion of various digestive glands. It needs to be at the end of the exercise? It will take 3 0 minutes to recover. If you eat in a hurry, it will increase the burden on the digestive organs, cause dysfunction and even cause many diseases.

Fourth, don't lower your body temperature: during exercise, the blood vessels on the body surface dilate, the body temperature rises, the pores relax, and sweating increases. If you enter the air-conditioned room immediately after exercise, or take a cold nap at the tuyere, or use a cold water punch to cool down, your skin will be tight and sweaty, causing physiological disorders such as body temperature regulation and decreased immune function, which will lead to diseases such as colds, diarrhea and asthma.

5. Don't smoke: Smoking after exercise is mixed with a lot of smoke in the air inhaled into the lungs. On the one hand, it reduces the oxygen content, which is not conducive to paying off the "oxygen debt" and it is difficult to eliminate physical fatigue. On the other hand, when the human body inhales this foggy air, it will affect the gas exchange in human alveoli, resulting in chest tightness, asthma, dyspnea, dizziness, fatigue and other symptoms due to insufficient oxygen supply after exercise.

6. Don't "omit" relaxation and finishing activities: Practice shows that relaxation and finishing activities can not only make athletes' cerebral cortex excited, but also speed up their heartbeat and breathing frequency, and can restore them to a quiet state before exercise through appropriate relaxation and bare-handed exercises, walking, relaxing massage, and relaxation exercises with good body network breathing rhythm, and also help to restore muscle fatigue, reduce the discomfort of acid swelling, and avoid dizziness, fatigue and nausea after exercise and fitness. Therefore, after each fitness, we should relax and arrange exercise, optimize the body network, so as to facilitate the recovery of the body and improve the fitness effect.
