运动饮食篇运动之前吃啥好

Will fasting before exercise burn more body fat?

锻炼前绝食会燃烧更多脂肪吗？

No, what you eat before exercising has little or no effect on fat burning (oxidation). The body uses stored fatand carbs as fuel in varying pro-portions, depending on the length and intensity of the activities and othervariables.

不会，你锻炼前吃什么几乎不影响脂肪燃烧（氧化）。人体使用所储存的脂肪和碳水化合物作为燃料，它们的比例取决于锻炼的时长和强度，或者其他因素。

Studies on fasting in athletes have produced inconsis-tent results, and when they have found extra fatburning it is very modest. And some research has shown that people burn more fat when they eatsomething before exercising than when they fast. What’s more, for most people, fasting before intense orprolonged exercise will reduce energy levels and impair performance.

研究表明运动员的绝食产生了与之前矛盾的结果，有些调查结果表明，人们在运动前先绝食再进食会燃烧更多脂肪，这是一个十分保守的说法特别是他们发现额外的脂肪燃烧时候。还有，对绝大多数人来说，在剧烈的长时间运动之前绝食，会降低能量水平和影响发挥。

Should you eat while exercising—and what?

你锻炼期间可以吃东西吗？吃什么？

Yes, if you’re doing prolonged events such as long- distance running or cycling. For most people, a fewhours of sustained, vigorous activity will deplete their stored carbs, resulting in weakness, fatigue, and/orpain—what’s known as “hitting the wall.” So it’s important to eat small high--carb (again, low in fat and fiber)snacks to maintain blood sugar and fuel your muscles and brain. You can also get the carbs from beverages.
