      If you continue to swim 400 meters or swim 100 meters, the energy provided by the anaerobic decomposition of blood sugar will be fully utilized. Therefore, a large amount of lactic acid will accumulate in the muscles after exercise, and lactic acid is a substance that causes muscle pain after exercise. The blood sugar required for this type of exercise is provided by starch, so it cannot burn fat and is not helpful for weight loss. If we increase the amount of exercise within these 15 seconds, or engage in instant explosive exercise, it will harm the body.

      The energy provided by the anaerobic decomposition of blood sugar (starch) usually only lasts for forty seconds, and is all used up after running 400 meters. If you stop at this time, all your previous efforts will be wasted. If you insist on running 800 meters, you will enter aerobic exercise for the next 400 meters. Your body must use blood sugar, blood fatty acids and blood amino acids in an aerobic state to synthesize a new heat energy substance, ATP, to provide energy. amount, blood sugar is supplied by the decomposition of starch, blood fatty acids are supplied by the decomposition of fat, and blood amino acids are supplied by the decomposition of protein. This whole process requires oxygen, that is, oxygen is used to burn starch, fat and protein to produce the heat energy substance ATP, which supplies the heat required for later exercise. The exercise in this latter part is "aerobic exercise".

      Therefore, if we run 800-1500 meters to lose weight and swim 200-400 meters, we need to start using oxygen to burn starch, fat and protein, so the latter part of this type of exercise is aerobic exercise.

      About five minutes before exercise, sugar is consumed first. The longer the exercise lasts, the more fat will be burned. As long as it lasts for half an hour to an hour, 50% of the calories consumed will be supplied by burning fat.

      But this does not mean that you can skip dieting. Even one hour of aerobic exercise can only burn the starch and fat in food, but cannot burn the fat originally accumulated in your body, and it is still useless for weight loss. Only one hour of aerobic exercise after dieting can have a chance to burn fat in the body.

      In short, only by doing aerobic exercise after dieting and dieting after aerobic exercise can the weight loss be effective.
