Precautions for swimming to lose weight:
At first, swimming was in the anaerobic exercise stage. Energy consumption mainly depends on anaerobic glycolysis of sugar. At this stage, the exercise is very intense, people are short of breath and lack of oxygen, and they don't use fat at all. Continue to exercise, and the human body begins to enter the stage of aerobic exercise. In the next hour, in the state of moderate intensity exercise, the aerobic metabolism of sugar provides energy supply. If you want to lose weight, you should swim for more than 40 minutes at a time before you start to burn fat.
Benefits of swimming to lose weight:
When exercising on land, obese people's bodies (especially lower limbs and waist) will bear great gravity load, which will reduce their exercise ability and make them easy to get tired, greatly reducing their 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.
