Precautions for sports diet:
1 First, eat a small amount of food before exercise. "Exercise on an empty stomach and just after eating is harmful to your health." Chongqing nutrition and sports experts said that eating a small amount of food half an hour before exercise can avoid digestive disorders caused by physical exercise and enhance the effect of exercise. If it is morning exercise, you must avoid indigestible food for breakfast, and it is best to eat a small amount of dairy products, cereals, fruits and drinks.
2. Second, replenish water in time during exercise. Chongqing nutrition and sports experts say that if you exercise for less than an hour, drink 150 to 300 ml of water every15 minutes. If the exercise time is 1 ~ 3 hours, you should replenish sugar water to your body in time to avoid hypoglycemia. In addition, don't drink ice water during exercise, because drinking ice water during strenuous exercise will cause digestive problems.
Also, don't drink water immediately after strenuous exercise, because after exercise, the metabolism of the human body is accelerated and sweat is discharged. Drinking water immediately will accelerate the loss of inorganic salts in the body, so take a break before drinking normal temperature water and light salt water.
3. Exercise consumes minerals such as calcium and magnesium. At the same time, calcium and magnesium supplementation will increase the burden on the stomach and easily lead to bad stomach. Drinking soft water is better, but the same mineral content will be less. So when you replenish water with soft water, you'd better eat some foods containing salt and minerals.
Hard water is suitable for supplementing mineral components such as calcium and magnesium after exercise. Because it is easy to increase the burden on the stomach, exercise can be taken in small amounts several times. Drinking hard water can also prevent leg cramps and muscle spasms during exercise.
Finally, it is not advisable to eat acidic food such as fish after exercise. Chongqing nutrition and sports experts said that after exercise, sugar, fat and protein are decomposed in large quantities. Without endogenous oxygen in the human body, acidic substances such as lactic acid and phosphoric acid will stimulate human tissues and organs, making people feel sore muscles and joints and mental fatigue.
Fish and other foods are acidic foods. Eating these acidic foods after exercise will make body fluids more acidic, which is not conducive to muscle and joint pain and fatigue. Experts suggest that you should eat more alkaline foods such as fruits, vegetables and bean products after exercise to maintain the acid-base balance in the human body, thus eliminating exercise fatigue and keeping healthy.
