1 sweat, be careful of dehydration.
Middle-aged men need water more than women. For men, muscle needs more than three times as much water as fat, while in men, muscle accounts for about 40%, while in ordinary women, muscle accounts for only a little more than 20%. Water can also lubricate joints, regulate body temperature, dissolve nutrients and transport them into human body. Generally, men need about two liters of water every day, while men who exercise use twice as much water.
2. Add chromium in time during physical exercise.
Chromium is an essential mineral to sustain life. It can reduce cholesterol in human body, increase endurance, make muscle grow and oxidize fat. High-quality grapes and raisins have the reputation of natural "chrome storehouse". Ordinary men can provide enough chromium by eating a bunch of grapes every day, and middle-aged men who participate in fitness exercises need to double it.
There is often congestion on the body, so vitamin K should be supplemented.
In the process of exercise, some people will have bruises or abrasions when they bump slightly, which is the performance of vitamin K deficiency. Vitamin K is a "hemostatic hero". Lack of it will delay blood coagulation, and in severe cases it will cause blood coagulation.
Cauliflower is rich in vitamin K. Eating cauliflower 2~4 times a week can relieve congestion or congestion. Secondly, asparagus and lettuce also contain vitamin K. Eating foods rich in vitamin K can not only strengthen the elasticity of blood vessel walls, but also prevent congestion and congestion.
4 exercise cramps pay attention to the supplement of calcium and magnesium.
The symptoms of leg cramps after exercise do not mean that you are overloaded with exercise, but are caused by insufficient nutrition. The main function of calcium and magnesium synergy in human body is to participate in neuromuscular conduction. Physical exercise easily leads to calcium and magnesium deficiency in human body, which in turn hinders neuromuscular conduction and leads to leg cramps.
The daily calcium requirement of middle-aged men is 1000 ~ 1800mg, and the recommended daily dietary amount of magnesium is 350 mg. There are many sources of calcium, among which milk is a good choice. Magnesium contained in green leaves is the most easily absorbed, and nuts and seafood are also rich in high-quality magnesium.
5 Poor sexual desire and zinc deficiency after exercise.
Zinc is called the "sex element" of men. Zinc deficiency in the body will affect the number and activity of sperm. For men who take part in fitness exercises, more zinc will be lost, especially when they sweat a lot, so zinc supplementation is particularly important for men who exercise regularly. Eating lean meat and steak is an effective way to get zinc. According to the determination, every100g lean beef can provide about 50% of the daily zinc demand. Seafood, mushrooms, lean meat, eggs and coarse grains are also rich in zinc.
