可以,如果你在做一些时间较长的运动,比如长距离跑步或者骑车。对大多数人而言,几个小时的持续有力的锻炼会消耗他们存储的碳水化合物,导致虚弱,疲惫或者酸痛。这就是众所周知的“撞墙”。因此吃一些少量高碳水化合物的零食很重要(同样要低脂和少纤维),有利于保持血糖平衡和为肌肉和大脑提供能量。你同样也可以喝饮料补充碳水化合物。
What's the best way to stay hydrated?
保持身体水分的最好方法是什么?
If you exercise moderately for less than an hour, all you need to do is drink when you’re thirsty—and wateris fine. But for prolonged exercise, especially in hot weather, drink plenty of fluids.
如果你运动量少于一个小时,你只需口渴的时候喝点东西就好了——喝水即可。但对于长时间的锻炼,特别是夏日炎炎的时候,那要喝足够多的液体。
The American College of Sports Medicine recommends drinking fluids (about 15 ounces for a 165-¬poundperson) at least four hours beforehand. Also drink at regular inter-vals during long workouts, even if you arenot thirsty, and drink adequately afterwards. For such endurance exercise, beverages with low to moderate sugar content as well as some potassium and sodium, such as sports drinks, are recommended.
美国运动药物大学建议锻炼前至少4个小时补充液体(15盎司或者165磅每人)。在长时间锻炼的休息间隔里也要补充,尽管你不渴,在锻炼之后要大量补充液体。对于像耐力训练这样的训练,建议喝像运动饮料,含有低或者中度的含糖量,同时补充钾和钠。
