Seven taboo tips for fitness

　　In a downturn exercise , will cause excessive physical fatigue or sports injuries, which will affect the quality of exercise and is not conducive to physical recovery and muscle growth, failing to achieve the purpose of exercise. Everything will go against its will.

　　Do not exercise after drinking alcohol

　　After the wine enters the body, it is quickly absorbed by the intestinal wall and enters the blood in about two hours. A small amount is excreted through urine and sweat, and most of it is detoxified by the liver. Because the cerebral cortex is extremely sensitive to alcohol. After drinking, the cerebral cortex becomes excited and restless for a short period of time. After a longer period of suppression, there is a feeling of slow response and drowsiness. At this time, the brain function is in an unstable state and the body's control ability decreases. If you exercise the cerebral cortex forcefully under such circumstances, it will damage brain function. Alcohol can also cause muscle fatigue. When muscles work, they require a large amount of oxygen supply from the blood, which often causes fatigue due to insufficient oxygen supply and an increase in lactic acid produced by the muscles. In addition, alcohol will accelerate the production and accumulation of lactic acid in muscles and slow down the elimination of lactic acid, which is not conducive to body recovery and affects muscle growth. It can be seen that drinking alcohol is taboo whether before or after fitness.

　　cold is to pause exercise

　　I have often heard rumors in the past: If you have a cold, it is okay to go to the gym to exercise and sweat. In fact, this statement is misleading. Some people think that cold symptoms will be relieved after participating in fitness exercises and sweating. This is because the human body interacts with each other during exercise nerve Excitement speeds up the heartbeat, accelerates breathing, improves the function of the defense system composed of white blood cells and other antibodies in the body, and when sweating, the toxins in the body are excreted faster, which can alleviate cold symptoms. This situation only occurs when the early symptoms of a cold are mild or in a small number of young people with strong immunity. For most people, participating in fitness exercises when they have a cold does more harm than good.

　　Do not exercise within one hour after meals

　　Going to the gym immediately after a meal can easily cause indigestion. For a period of time after eating, the food in the gastrointestinal tract fills the diaphragm and affects breathing, which is unfavorable for exercise. And after eating, the blood is concentrated in the digestive system. If you perform fitness exercises at this time, the blood will be dispersed into the motor organs to supply muscle work, which will affect the digestion and absorption of things. In addition, the working capacity of the motor organs is also reduced due to insufficient blood supply, and they are prone to dizziness, paleness, vomiting and other maladaptive reactions.

　　Do not exercise on an empty stomach

　　Low fasting blood sugar. During low blood sugar, there is insufficient oxygen supply to the brain, and distraction can cause dizziness and weakness in the limbs. In severe cases, symptoms such as shock may occur, making it difficult to complete the fitness plan. If the body does not store carbohydrates (sugar) to provide fuel for exercise, more muscles will be consumed during exercise.
