长跑运动项目具有持续时间长、运动中无间歇及物质代谢以有氧氧化为主导的特点,因此膳食应提供足够的热能。耐力性项目运动员缺铁性贫血的发生率较高,因此应提供足够的蛋白质和铁。由于运动时间长,运动强度相对较低,运动员体内脂肪的动员和利用率高,所以应提供适量的脂肪。耐力运动中大量出汗使水分、电解质丢失,应适量补液,维生素的供给应随热能消耗量的增加而相应提高。 耐力运动员碳水化合物占总热量的比例应大于60％～70％。运动前、中、后适量补糖可以提高肌糖原水平,维持血糖于较高水平,使运动后的肌糖原尽快
Long-distance running sports with long duration, no intermittent movement and the material metabolism is dominated by aerobic oxidation, so the diet should provide enough heat. Endurance athletes have a high incidence of iron deficiency anemia and therefore should provide adequate protein and iron. Because exercise time is long, exercise intensity is relatively low, mobilization and utilization of body fat fat athletes, it should provide the right amount of fat. Endurance exercise a lot of sweating so that water, electrolyte loss, should be appropriate rehydration, vitamin supply should be increased with the increase of heat energy consumption. Endurance athletes carbohydrate ratio of total calories should be greater than 60% to 70%. Exercise before, during and after the right amount of sugar can increase the level of muscle glycogen, maintain high blood sugar levels, so that muscle glycogen after exercise as soon as possible
