研究表明平时不运动，周末集中锻炼一样好？
去年，巴西圣保罗联邦大学（Federal University of São Paulo）的研究表明，工作日没时间锻炼，只在周末锻炼仍可降低早逝风险。
近日，美国麻省总医院（Massachusetts General Hospital）研究人员的最新研究得出了类似结论：如果你能在周末锻炼至少150分钟，那么你可能就不需要在工作日内额外锻炼了。
该研究表明，每周集中一到两天进行锻炼，对心脏健康的好处与在一周内分散进行锻炼的好处一样。

Skipping weekday workouts? Weekend-only exercise offers similar benefits, study finds
From: CBS NEWS
For many people, weekdays mean a lot of work and not a lot of time for working out. But according to recent research, you may not need to exercise during the week if you work out for at least 150 minutes over the weekend.
The study, published in JAMA, the journal of the American Medical Association, followed almost 90,000 people, and found that moderate to vigorous activity, concentrated during one or two days a week, offers similar cardiovascular benefits to a similar amount of exercise spread throughout the week.
"I think it's empowering to say it doesn't matter so much how you get it. The important thing is that you do get it," says Dr. Shaan Khurshid, a cardiologist at Massachusetts General Hospital, who led the study.
Whether it's a weekend run, bike ride, soccer match or a brisk walk — it all counts.
"As a physician, there's frequently kind of a rule of thumb that we say, you know, 30 minutes, five days a week," Khurshid says. "It makes sense in certain schedules, but that is also very difficult to achieve for other people who only have the weekend available or only have one or two days a week."
The research is also great news for weekend warriors like Kathy Odds, who meets up with a running group on Saturdays.
"I work for a bank, so it's a pretty long day most days. So finding the times to fit exercising can be tricky," she told CBS News. "What I love most about the weekend exercise (is) the opportunity to socialize. So not only is it my physical well-being that I'm looking after, it's also my mental well-being."
Utilizing time on the weekend to workout can also help when the days get shorter and darker sooner.
Other research, however, has shown benefits of less intense but more frequent movement, especially for those who sit a lot during the workday.
Dr. Keith Diaz, an exercise physiologist at Columbia University Irving Medical Center, previously told CBS News his research found quick strolls throughout the day could go a long way for your health.
"We found a five-minute light walk every half-hour offset many of the harms from sitting," he says. Spending too much time sitting can increase the risk for heart disease, diabetes and even some forms of cancer.
