A new study shows women need 60 minutes of moderate exercise a day to prevent weight gain as they age if they consume a normal diet.
一项新的研究显示，随着女性年龄的增长，在正常饮食的情况下，她们需要每天进行60分钟中等强度的运动，才能避免体重增加。
The findings suggest women need more exercise than the current federal guidelines of 150 minutes a week, or 30 minutes five days a week, of moderate-to-intense activity.
研究结果显示，女性需要的运动量要大于目前联邦指南建议的每周150分钟中等强度至高强度运动（相当于每周锻炼五天，每天30分钟）。
The study is being published in the March 24/31 edition of the Journal of the American Medical Association.
该研究报告发表在3月24日-31日的《美国医学会期刊》上。

该研究首席研究员、哈佛医学院和波士顿布里格姆妇女医院医生兼副教授I. Min Lee说，我不希望人们举手投降说，“我做不到”。
