Carbohydrates and fats Children and adults may differ in their preference for carbohydrates or fats. Young children prefer to use fat to supply energy, and the ability to use carbohydrates tends to be lower. These metabolic differences gradually disappear throughout puberty, especially among boys. Therefore, it seems that children are less dependent on carbohydrates, but this difference may affect actual recommendations. In adults’ long-term exercise, carbohydrates can improve athletic performance, and studies have shown that children are no exception. The delivery of carbohydrates requires a gastrointestinal system that is well able to absorb carbohydrates. In the early stages of development, the gastrointestinal system's ability to grow and absorb carbohydrates will gradually increase, Metal Coils and it will have a good absorption capacity at the age of five. The recommended intake of carbohydrates during exercise depends on the time of exercise (and intensity). Children's exercise time is generally shorter, absolute exercise intensity is lower, and the demand for carbohydrates during exercise is also lower. Hydration One of the main ways to dissipate heat in children and adults is through the evaporation of sweat from the skin. Because children have a higher ratio of body surface area to body weight (about 50% higher than adults at 8 years old), it is said that children should be able to dissipate heat faster than adults when exercising. But on the other hand, children's sweat glands are less developed, so it may be difficult to dissipate heat only by sweating. In fact, during training, adults and active children have similar body temperatures, even at high temperatures. The current adult guidelines take into account the rate of sweating. If you sweat too much and cause your weight to drop by more than 2%, you should replenish your water. The goal of hydration should be to control weight loss between 0 and 2%. Both weight gain and excessive reduction should be avoided. This also applies to children, as these recommendations have been based on individual sweat rates.
