A study conducted by Arizona State University also recently found similar results when they studied the effects of aerobic exercise on overweight women.
近日，亞利桑那州立大學(xué)也進(jìn)行了關(guān)于有氧運動對超重女性有何效果的研究，該研究結(jié)果與之相似。

The researchers asked 81 women who had a sedentary lifestyle to participate in a 12 week aerobic exercise program involving three treadmill sessions a week. They were also asked not to alter their diet.
研究人員邀請了81名平日有著靜態(tài)生活方式的女性參加了一個12周有氧運動計劃，平均每周有三次在跑步機上的鍛煉機會，同時研究人員也要求她們不要改變自己的飲食習(xí)慣。

The end result found that while they were fitter after twelve weeks, they also were fatter. There was no noticeable weight loss amongst the group and almost 70 per cent of the women had piled on some fat mass during the program.
研究最終結(jié)果表明，盡管12周后她們或許變得比以前健美了一些，但同時也比以前胖了。這組女性并沒有顯著的減重成果，其中近70%的女性在參與這一計劃后堆積了更多的脂肪。

Jowett says the important thing to note is that fitness and weight loss are different ball games. He believes it's a 80/20 ratio with 80 per cent being about what we eat and 20 per cent exercise.
喬伊特稱有重要的一點需要我們注意，那就是健身與減重是截然不同的兩個概念。他認(rèn)為80%與20%的比率才是恰當(dāng)?shù)模渲?0%是關(guān)于我們的飲食，20%關(guān)于運動。

So what counts as strenuous exercise? 'Anything that you assess on a "Relative Perceived Exertion" scale, with one being easiest and ten being harmful,' says Jowett.
那么到底什么算是劇烈運動呢？喬伊特說：“可以用相對自覺運動強度指數(shù)來衡量，1表示很輕松，10就表示對身體有損害了。”

'A brisk walk is good because you can still talk, but if you're doing exercise that feels above a seven like running, cycling, aerobics, Cross Fit, then it won't be good for weight loss,' he said.
他說：“快走就屬于十分好的運動，因為在散步的同時你還可以說話。但如果你進(jìn)行超過七分體力的運動，例如跑步，騎單車，有氧運動，交叉健身等，這些都可能不利于減重。”
