Swimming needs a lot of energy and consumes a lot of energy. If the moving speed is the same, complete the same set of actions. It's six times more powerful than land. At the same time, the thermal conductivity of water is 26 times that of air. At the same temperature, people consume more than 20 times as much heat in water as on land. Moderate intensity swimming consumes about 300 ~ 500 calories/hour. So even if it is important to replenish physical strength, it is natural to eat after swimming.
What is better to eat after swimming?
After swimming, the human body absorbs 2-3 times as much food as usual. You should choose digestible foods, such as vegetables and rice, but not too much. Due to the strong hunger after swimming, quite a few people will eat a lot of food at a time, which is easy to cause excess energy and lead to obesity. If you are losing weight, don't eat high-fat and high-calorie foods (such as fried food and fat) after swimming, otherwise the physical energy consumed by swimming will be wasted. One of the best choices after swimming is bean products and lean meat. This can not only supplement high-quality protein, but also have the advantage of low fat. Of course, vegetables and staple foods can also be used.
What is better to eat when swimming?
After swimming for an afternoon, it is inevitable to go ashore two or three times. At this time, you often want to eat snacks or drink something. Remember, don't drink sugary drinks such as cola and sprite at this time, because the body is the easiest to absorb calories quickly at this time. It is best to decorate warm water or tea in the sports cup in advance and drink it between swimming. If there is no water, choose mineral water or sugar-free tea! In this process, it is good to eat snacks, but don't eat too much or too full. Eating some cucumbers, cherries and apples with fresh taste and low sugar content can relieve hunger and replenish some energy to the body. In addition, you can eat 1-2 slices of whole wheat or oatmeal bread, but not too much. Don't eat bread and butter or cake.
What to eat before swimming?
Remember three principles before it is too late. Don't swim on an empty stomach. Swimming on an empty stomach is easy to cause hypoglycemia, which makes swimmers dizzy, weak and even faint. Don't swim when you are full. Just after eating, the blood is concentrated in the stomach. At this time, swimming will force the whole body blood to flow back to the limbs, resulting in decreased blood in the stomach, indigestion of food, and a series of uncomfortable symptoms such as "breathlessness" and "stomach discomfort". Recommend digestible and high-energy foods. For example, it is suggested that beef should be cooked, which is easier to digest, so as to avoid overloading the small intestine that is absorbing nutrients during swimming after meals 1 ~ 2 hours.
