Strength is practiced alone, with equipment and the like. It is different from aerobic exercise, which is a basic and necessary thing.
It is not advisable to squat and rest after fitness. If you squat down and rest immediately after fitness exercise, it will make the blood of lower limbs return, affect blood circulation, deepen physical fatigue, and even cause gravity shock or sudden death in severe cases. Therefore, after each exercise, we should adjust the breathing rhythm, swing our arms during walking, 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 physical fatigue.
It is not advisable to indulge in cold drinks. Exercise often makes people sweat. With the consumption of a lot of water, people always feel thirsty after exercise and need to drink water urgently. But at this time, the digestive system of human body is still in a state of inhibition and its function is low. If you try to quench your thirst for a while and eat a lot of cold drinks for a while, it is easy to cause gastrointestinal cramps, abdominal pain, vomiting and induce gastrointestinal diseases.
Not suitable for immediate consumption. During exercise, especially during strenuous exercise, the central nervous system that manages muscle activity is in a state of high excitement. Under its influence, the parasympathetic nervous system, which manages the activities of internal organs, has strengthened its inhibitory effect on the activities of digestive system. It takes 20-40 minutes to recover after the exercise. If you eat in a hurry, it will increase the physiological burden of digestive organs, cause dysfunction, and even cause many diseases in severe cases.
A sudden drop in body temperature is not desirable. During exercise, blood vessels on the body surface dilate, body temperature rises, pores dilate and sweating increases. If you go into 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 tighten and stop sweating, leading to physiological disorders such as body temperature regulation and decreased immune function, resulting in symptoms such as colds, diarrhea, asthma and wind-cold pain.
It is not advisable to take a hot bath immediately. It is dangerous to take a hot bath immediately after fitness exercise. Because a large amount of blood in the body is distributed on the limbs and body surface during exercise, once the exercise stops, the increased blood flow will continue for some time. If you take a hot bath at this time, it will increase the blood flow to the skin, causing too much blood to enter the muscles and skin, resulting in insufficient blood supply to the two main organs of the human body-the heart and the brain.
Smoking is not advisable. Smoking after fitness exercise, the air inhaled into the lungs is mixed with a lot of smoke, on the one hand, it will reduce the oxygen content, which is not conducive to paying off the "oxygen debt" and it is difficult to remove physical fatigue; On the other hand, when the human body inhales this foggy air, it will affect the gas exchange in the alveoli of the human body, resulting in chest tightness, asthma, dyspnea, dizziness and fatigue due to insufficient oxygen supply after exercise.
It is not appropriate to "omit" relaxing and tidying up activities. Practice shows that relaxation and finishing activities can not only make athletes' cerebral cortex excited, but also accelerate their heartbeat and breathing frequency, and through appropriate relaxation exercises, such as bare hands, walking, relaxing massage, breathing rhythm relaxation exercises, etc., athletes can return to the quiet state before exercise. Moreover, relaxation and finishing activities are helpful to restore muscle fatigue, reduce discomfort caused by acid swelling, and help to avoid adverse physiological reactions such as dizziness, fatigue, nausea, vomiting and dizziness after exercise and fitness. Therefore, actively and effectively completing the relaxation and finishing activities after fitness exercise should be regarded as one of the indispensable and important contents of fitness exercise itself.
It is not advisable to swim when sweating. On the one hand, when sweating after exercise, the capillaries on the body surface dilate and a large amount of heat is emitted in the body. When swimming at this time, the capillaries will suddenly contract due to the stimulation of cold water, forcing the blood flow to slow down and reducing the body's resistance, and germs and viruses will take advantage of it and make people sick; On the other hand, after sweating heavily, the body will lose electrolytes, glycogen and water-soluble vitamins. Once the muscle is stimulated by cold water, the excitability of the muscle increases, which leads to muscle spasm and drowning accident.
It is not advisable to supplement pure water. It is not advisable to drink too much water during exercise. If you drink too much water, it will cause symptoms such as stomach muscle spasm and abdominal pain. After a few minutes of strenuous exercise, you should properly replenish water. Pure water contains almost no salt and minerals excreted by human sweat. When people do strenuous exercise at high temperature, they sweat a lot, which leads to the loss of water and salt in the body. If you drink plenty of water and don't replenish salt in time, the concentration of sodium chloride in the blood will decrease and the muscle excitability will increase, which will easily cause muscle spasm and pain. So before training, you should add enough water and salt; Pay attention to the alternate movement of all muscle groups in the whole body during exercise, so as to avoid overloading local limbs by exercising only local limbs.
It is not advisable to eat a lot of sugar. Some people feel comfortable eating sweets or sugar water after strenuous exercise, and think that eating sweets after exercise is good. In fact, eating too much sweets after exercise will consume a lot of vitamin B 1 in the body, and people will feel tired and lose appetite, which will affect the recovery of physical strength. Therefore, it is best to eat more foods containing vitamin B 1 after strenuous exercise, such as vegetables, liver, eggs and so on. If you like sweets after exercise, you should eat more vegetables and other foods.
