Do I Burn More Calories Running Outside or on a Treadmill?
室外跑步，跑步機跑步，哪個消耗的卡路里多？Question: Do I Burn More Calories Running Outside or on a Treadmill?
問題：室外跑步，跑步機跑步，哪個消耗的卡路里多？I've heard that running outside burns more calories than running on a treadmill. Is that true?
我聽說在室外跑步比起在跑步機上跑步能消耗更多的卡路里。這說法對嗎？
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：這實際上取決於你跑得有多快。對一般人來說速度在5到9mph之間，一些研究表明室外跑可以多消耗5%的卡路里，然而另外一些研究卻認爲沒有什麼差別。但是如果你是以很快的速度跑的話--超過10mph（1英里6分鐘）--你也許比室外跑多消耗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.
在跑步機上跑步身體或多或少會感覺輕鬆些因爲你腳下的地面在被往後拉，而且沒有風的阻力，所以這可以解釋消耗卡路里量的不同。在室外你跑得越快，抵抗風的阻力就越困難。如果你想在跑步機上更好地模擬室外跑步，你可以在跑步機上設定1%的坡度。Also, keep in mind that those calories burned displayed on treadmills are not accurate. Some reports suggest that treadmills and other cardio machines actually overestimate calories burned by up to 15-20%.
還有，記住跑步機上顯示的消耗掉的卡路里的量是不準確的。一些報告表明跑步機和其他的一些心肺機其實高估了消耗的卡路里的量，達到15%-20%。
