Do I Burn More Calories Running Outside or on a Treadmill? 室外跑步，跑步机跑步，哪个消耗的卡路里多？ Question: Do I Burn More Calories Running Outside or on a Treadmill? 问题：室外跑步，跑步机跑步，哪个消耗的卡路里多？ I've heard that running outside burns more calories than running on a treadmill. Is that true? 我听说在室外跑步比起在跑步机上跑步能消耗更多的卡路里。这说法对吗？ Answer: It really depends on how fast you're running. For the average person running at 5 to 9 mph, some research shows that outdoor running burns up to 5 percent more calories, while other studies show no difference. But if you're running at a quick pace -- faster than 10 mph (6 minutes per mile) -- you may be burning up to 10 percent more calories when you run outside. 答案：这实际上取决于你跑得有多快。对一般人来说速度在5到9mph之间，一些研究表明室外跑可以多消耗5%的卡路里，然而另外一些研究却认为没有什么差别。但是如果你是以很快的速度跑的话--超过10mph（1英里6分钟）--你也许比室外跑多消耗10%的卡路里。 Running on a treadmill is somewhat easier physically because the ground is being pulled underneath your feet and there's no wind resistance, so that may explain the difference in the amount of calories burned. The faster you run outside, the harder you're working against wind resistance. If you want to better simulate outdoor running conditions on the treadmill, you can set your treadmill at a 1% incline. |
