Swimming to lose weight Swimming is a systemic exercise, which can not only lose weight, but also improve your cardiopulmonary function, and can exercise almost all your muscles, especially by insisting on regular intensive training, and you can be "thoroughly transformed" in a few months. In the water, people's bones are fully relaxed, and they can have the opportunity to "stretch", which is conducive to maintaining a tall and straight figure. For growing teenagers, regular swimming exercise can make you grow into a "tall man". (1) Swimming consumes a lot of energy. This is because the resistance of water when swimming is much greater than that of air when moving on land, so it is very difficult to walk in the water, and then swimming will definitely consume more calories. At the same time, the thermal conductivity of water is 24 times higher than that of air, and the water temperature is generally lower than that of air, which is also beneficial to heat dissipation and consumption. So swimming consumes much more energy than running and other land projects, so the effect of losing weight is more obvious. ⑵ It can avoid sports injuries of lower limbs and waist. When carrying out weight-loss exercise on land, because obese people are heavier, their bodies (especially lower limbs and waist) have to bear great gravity load, which reduces their exercise ability, is easy to fatigue, greatly reduces their interest in weight-loss exercise, and can damage joints and bones of lower limbs. When swimming in water, a considerable part of obese people's weight is borne by the buoyancy of water, which makes their lower limbs and waist much easier and greatly reduces the risk of joint and bone injury. ⑶ You can enjoy natural massage service: When swimming, the buoyancy, resistance and pressure of water are an excellent massage for the human body, and can also beautify the skin. The resistance of people moving in water is 12 times greater than that on land. When their hands and feet move in the water, you must feel strong resistance, so the muscles of back, chest, abdomen, buttocks and legs can be well exercised in swimming. Swimming is also an intense sport. The heat transfer speed of water is faster than that of air, which means that people will lose heat quickly in water, and swimming will consume a lot of heat. Excess body fat will also "dissolve in water" quietly. In order to get a good exercise effect, you need to exercise in a planned way: beginners can swim for 3 minutes in a row, then rest for 1-2 minutes, and swim twice for 3 minutes each time. If you don't finish it with great effort, you can enter the second stage: swim continuously at an average speed of 10 minute, rest for 3 minutes, and do three groups at a time. If you still feel relaxed, you can start swimming for 20 minutes at a time until it increases to 30 minutes at a time. If you feel that the intensity is increasing too fast, you can follow your own acceptable rhythm. In addition, swimming consumes a lot of energy, so it is best to do it every other day to give your body a recovery time. When swimming, people's metabolism is very fast, and they can consume 1 100 kilojoules of heat in 30 minutes, and this metabolic rate can be maintained for a period of time after you leave the water, so swimming is an ideal way to lose weight. For thin people, swimming can actually make them gain weight, because swimming exercises muscles and increases their volume and weight. It can be said that swimming can make fat people swim thin and thin people swim fat, which can make everyone have a smooth line. In view of the above reasons, obese people can really take swimming as the main exercise to lose weight. But you must be prepared before swimming and pay attention to safety to prevent accidents.
