The beauty of lines has two factors:
One is that swimming is an excellent choice for body shaping. When swimming, the body is directly immersed in water, which not only has great resistance, but also has very good thermal conductivity and fast heat dissipation, so it consumes more heat. Like a boiled egg, the cooling rate in air is far less than that in cold water. Experiments show that the heat consumed by a person running in a standard swimming pool for 20 minutes is equivalent to running at the same speed on land 1 hour, and staying in water with 100 minutes is as high as 100 kcal, which is equivalent to being in air with the same temperature. In addition, swimming diet can avoid sports injuries of lower limbs and waist. When you exercise on land to lose weight, your body (especially lower limbs and waist) will bear great gravity load because of the heavier weight of obese people, which will reduce your exercise ability and make you tired easily, thus greatly reducing your interest in losing weight and damaging the 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. It can be seen that water sports make many people who want to lose weight get twice the result with half the effort. Therefore, swimming is one of the most effective aerobic exercises to keep healthy.
When swimming, they usually use the buoyancy of water to lie prone or supine in the water, so that the whole body can be relaxed and stretched, so that the body can develop comprehensively, symmetrically and harmoniously, and the muscle lines are smooth. Exercise in water reduces the impact of the ground on bones, reduces the probability of bone aging, and the joints are not easy to deform. The resistance of water can increase people's exercise intensity, but this kind of intensity is very soft, which is different from the equipment training on land. The training intensity is easily controlled within the aerobic range, so that stiff muscle blocks will not grow and the whole body lines will be smooth and beautiful.
At the same time, swimming can improve people's basal metabolic rate (BMA) and give people a healthy and beautiful figure. The picture of people swimming in the water will give people a streamlined association, so the word linear beauty was born.
Swimming with the coach for more than 2 years, most of the boys who train together have strong and beautiful muscles, but they are not as strong as bodybuilders. They belong to the kind of clothes that are thin and undressed, while women are not easy to grow muscles because of hormone secretion, and girls are well-proportioned and slender. For example, swimmers in international competitions are well-proportioned

1. Fitness supplement: This is fitness for the purpose of exercising heart, lung and blood functions. This kind of non-professional fitness will not build muscles. (Although girls are a little scary. They will take drugs such as androgen for muscles. ) See Baidu Encyclopedia Fitness for details.
2. Aerobic exercise: refers to the physical exercise carried out by the human body under the condition of sufficient oxygen supply. That is, in the process of exercise, the oxygen inhaled by the human body is equal to the demand, achieving physiological balance. Simply put, aerobic exercise refers to any rhythmic exercise, which lasts for a long time (about 15 minutes or more) and has moderate or above-average intensity (75% to 80% of the maximum heart rate). It is characterized by low intensity, fast rhythm and long duration. It is required to exercise for at least 30 minutes at a time and insist on 3 to 5 times a week. This kind of exercise, oxygen can not only fully burn (that is, oxidize) the sugar in the body, but also consume the fat in the body, enhance and improve the cardiopulmonary function, prevent osteoporosis, and adjust the psychological and mental state, which is the main exercise mode of fitness. Therefore, if you are overweight and want to lose weight through exercise, it is recommended to choose aerobic exercise.
3. list of fat burning aerobic exercise: NO 1, and the calorie consumption of taekwondo: about 700 kcal/hour.
NO2, swimming heat consumption: about 650 kcal/ hour.
NO3, jogging heat consumption: about 650 kcal/ hour.
4. Basal metabolic rate: Basal metabolic rate (BMR) refers to the energy metabolic rate when the human body is awake and extremely quiet. People with high basal metabolic rate (BMA) consume more energy when doing the same intensity exercise than those with low BMA. For example, some slim and beautiful women, who only eat a little food every day, have loose muscles and no health and vitality, are examples of low BMA.
Part of it comes from the basal metabolic rate of swimming aerobic exercise in Baidu Encyclopedia.
