It is not advisable to go swimming quickly after fitness. Don't ignore that strength exercise and moderate intensity aerobic exercise have their own emphasis on human health care. If the two exercises are properly coordinated, their functions can complement each other and achieve twice the result with half the effort. However, without the guidance of professional coaches, ordinary people should be cautious about this set-meal fitness program. It is dangerous to swim in cold water immediately after strenuous exercise. Because the various systems of the body have not returned to a quiet state, blood flow is accelerated, capillaries are opened, heart rate is accelerated, blood pressure is raised, and body temperature is raised. At this time, it was immediately stimulated by cold, and the cold was mild, which led to the invasion of dampness, causing arthritis and rheumatic pain. In summer, exercise consumes a lot and sweat is lost. If you exercise outdoors, ultraviolet rays are harmful to your skin. Therefore, it is important to supplement nutrition. It is recommended to drink sports drinks and natural protein powder. Fitness people can also make their own nutritious water. The formula is 500ml mineral water +5g glucose +2g salt (one teaspoon tip) +2g honey. You can also use green tea brewed by Maojian instead of mineral water. It should be noted that you should not drink frozen sports drinks and water, otherwise it will easily lead to increased gastrointestinal peristalsis, severe abdominal pain and diarrhea. Drinking a small amount of water many times during exercise is the correct way to replenish water. Eat more seasonal fruits and vegetables after exercise. Cooking meals should pay attention to digestibility and nutrition, and boiling and stewing are better. In order to reduce unnecessary physical injury, exercise time should avoid when ultraviolet radiation is strong. The order of anaerobic before aerobic is correct, but it is recommended not to go to the swimming pool sweating all over. First, it is easy to catch a cold. Second, when sweating, the human body emits moisture. At this time, entering the water is easy to accumulate moisture in the body, and the moisture in the human body is the most difficult to remove. It's best to wait until you stop sweating.
