　　All girls have a proud figure Dream There is nothing wrong with this, female It is also natural to love beauty, but for girls with poor figure, the road to losing weight is long. So, how do women lose weight in summer? Is swimming effective?

　　Swimming is a whole-body exercise that helps improve your cardiopulmonary function and can exercise Muscles, human bones are fully relaxed in water, can there be a chance? “Stretch", which is very good for maintaining a tall and straight figure. Regular swimming exercises can also help you "grow taller". This is because the resistance of water during swimming is much greater than the resistance of air during land exercise. Walking in the water is laborious, and swimming again will definitely consume more calories. At the same time, the thermal conductivity of water is 24 times greater than that of air, and the water temperature is generally lower than the air temperature, which is also beneficial to heat dissipation and heat consumption. Therefore, the energy consumed during swimming is much greater than that in land-based sports such as running, so the weight loss effect is more obvious.

　　In summer, there is no more economical and affordable sport than swimming. It's so hot, it feels so good to jump into the water. Data show that the thermal conductivity coefficient of water is 26 times greater than that of air. If the heat is lost in water of the same temperature, it is more than 20 times faster than in the air, effectively consuming human heat. Tests show that swimming 100 meters in water consumes 100 kilocalories of heat energy, which is equivalent to running 400 meters on land, riding a bicycle 1,000 meters, or skating 1,500 meters. In addition, “due to the action of water waves, the skin of the human body is constantly rubbed, thereby causing skin Get relaxation and rest, so people who swim regularly will have smooth and soft skin."

　　Swimming to lose weight common sense

　　before swimming

　　1. It is best to exercise two hours after a meal

　　Regardless of whether women choose to swim during the day or at night, they should start exercising two hours after a meal. During this time, sugar and food can be fully decomposed, and fat can be consumed as quickly as possible during swimming. Secondly, the food in the abdomen is affected by the water pressure during swimming, which can cause nausea and vomiting.

　　The Beauty-loving Women's Network recommends that women choose to swim after dinner to avoid getting tanned and at the same time consume the oil accumulated throughout the day, and finally have a good night's sleep.

　　2. Supplement high-protein and high-calcium foods

　　Swimming is a whole-body exercise, and the muscles of the back, chest, abdomen, buttocks and legs can be well exercised in swimming. Swimming for 30 minutes can burn more than 260 calories, which is equivalent to 60 minutes of aerobic exercise. Before swimming, girls should choose to eat high-protein foods, such as egg , meat, soy products and some sugary sweets, but don’t eat too much, just 70% full. At the same time, in order to prevent cramps, women can also drink a glass of salt water or take some calcium tablets before swimming. This can also replenish mineral elements such as calcium, potassium, and phosphorus that are lost during swimming.

　　3. Adjust your swimming mentality

　　Before going into the water, many women have the mentality of "swearing to lose weight and swim to the end" and have to make themselves exhausted before they give up. They wish they could lose 3 or 4 pounds in one go. In fact, this is a very unscientific idea. Losing weight cannot be achieved overnight. You must first learn to regard swimming as a lifestyle habit. Only long-term exercise can reduce fat.

　　Some women are afraid of swimming and get up after staying underwater for twenty minutes. In fact, swimming exercise for less than thirty minutes has no weight loss effect. The fear of swimming is because they have not mastered the correct swimming method. Women can find a patient swimming coach to teach themselves how to move freely in the water.

　　4. Replenish water at any time

　　When swimming, women may feel that they are not sweating. In fact, this is an illusion. Girls' whole body is subject to the resistance of water, which keeps all parts in motion. However, the water temperature is lower than the body temperature, and heat transfer is fast. It is difficult for the body to accumulate heat in the water, and the sweat is taken away by the water flow, so even if it is "sweaty", it does not feel.

　　A test data on the Australian swimming team showed that after swimming 500 meters, body fluids will be lost by 160 ml. Every 30 minutes of exercise, the human body will lose about 700ml of water. It can be seen that swimming consumes a lot of water. It is best for girls to drink water every 20-30 minutes, and the total amount should be kept at about 1000ml. Do not wait until your mouth is dry before drinking water, because your body is already very dehydrated by then.

　　5. Use the athlete’s method of swimming

　　The optimal speed for swimming to lose weight should be above 35 meters per minute. Athletes generally swim in sections with short rest periods. MMs can also learn from this method and adopt a rotation method of exercise and rest. The rest time is less than the swimming time. Swim for 3 minutes, rest for 1 minute, then swim for 3 minutes and rest for 1 minute. If you still don’t feel tired after two sets of such exercises, you can continue swimming for 5 minutes and rest for 2 minutes. Maintain a cycle of exercise and increase the continuous swimming time and rest time appropriately.

　　MM's exercise plan must be reasonably arranged within the body's tolerance. In addition, swimming consumes a lot of physical energy. When you first start exercising, you can swim once every two days to give your body sufficient recovery time. Once you get used to it, you can exercise every day.
