Previous studies have shown that carbohydrate supplementation during endurance exercise delays fatigue. While exogenous glucose maintains blood glucose levels in later exercise, it causes reactive hypoglycemia at the start of exercise. In contrast, fructose is not oxidized as efficiently by the muscles nor does it elicit the typoglycemic effect. For these reasons, the purpose of this study is to determine a concentration of glucose-fructose beverage which maintains blood glucose levels throughout exercise, thereby delaying fatigue in endurance exercise.

以前的研究表明，在怀孕期间补充碳水化合物 耐力运动可以延缓疲劳。 而外源性葡萄糖维持 在以后的运动血糖水平，它会导致反应性低血糖 在运动开始时。 相比之下，果糖不被氧化， 也不会引起典型的血糖效应。 基于这些原因，本研究的目的是确定一个 葡萄糖-果糖饮料维持血液的浓度 葡萄糖水平在整个运动，从而延缓疲劳， 耐力训练
