Swimming is also aerobic exercise, which can lose weight. According to the common sense of sports, a certain intensity of aerobic exercise has the effect of losing weight. Swimming, as an aerobic exercise, certainly has the effect of losing weight. People need to move their limbs when swimming, and they need to use all their muscles to keep their bodies moving, which of course consumes calories. The human body can lose weight by burning calories.
Water has great resistance, which can help the human body consume more calories. Unlike aerobic exercise on the ground, water has great resistance. When people move in the water, they always feel the resistance of the water. In order to resist this resistance, the human body will inevitably make more efforts during exercise, that is, it will pay more calories, which is obviously beneficial to lose weight.
Water has better thermal conductivity than air. Water conducts heat better than air. For example, if we take something out of the refrigerator, the melting time in water is obviously shorter than that in air, which means that the thermal conductivity of water is better than that of air. Similarly, when we are immersed in water, even if we don't exercise, the water will take away the heat from our body. At this time, if we swim with a certain intensity, the weight loss effect will naturally be good.
Swimming can avoid the injury of lower limb joints. Many aerobic exercises on the ground, such as long-distance running and mountain climbing. If the ground is too hard or the posture is incorrect, it is easy to impact the joints of lower limbs, thus causing joint damage. Swimming can effectively avoid the influence of exercise on joints, because people are floating in the water when swimming and will not impact the joints of lower limbs. This is also the difference between swimming and general aerobic exercise.
In fact, swimming not only has the function of losing weight, but also has the functions of strengthening muscle strength, shaping body shape, improving heart and lung function and improving human body's tolerance to temperature, just like other aerobic exercises.
