研究显示少许10分钟散步比一次长时间散步更有益

2006年9月17日，星期天，HealthDay新闻—一项新近的研究显示每日四次散步比一次长时间散步降压效果更明显。
高血压杂志9月号报道，印第安纳大学研究人员对20名高血压前期患者进行研究，对比每日四次散步和一次长时间散步降压效果。
高血压前期（即血压范围高压120-139 mm Hg ，低压80-89 mm Hg）血压常会进展到高血压水平。高血压常与心脏病、心衰、肾衰、中风和失明相关联。
研究人员发现虽然长时间散步和短时间散步降血压程度相同，但短时间散步持续效果11小时，而长时间散步只能持续7个小时。
印第安纳大学，健康、体育和恢复学校的运动机能学教授Janet Wallace在一次发言中说：我们并不是说短时间运动更好，大多数文献中报道长时间持续运动比多次间断运动更有效。但这些研究结果会鼓励本不适于持续运动的人群去进行长时间运动。
对于大多数人来说最大的问题是他们缺乏时间。你可能想，我没有将近40分钟的时间去健身房或锻炼，但是我可以有10分钟在这，或10分钟在那。4个10分钟散步将是非常完美的。

Four Short Walks a Day Ease Blood Pressure
A few 10-minute strolls are even healthier than one long walk, study shows

SUNDAY, Sept. 17 (HealthDay News) -- Taking four short walks a day to lower your blood pressure may be more effective than one long walk, a new study finds.
Reporting in the September issue of the Journal of Hypertension, Indiana University researchers compared the effects of four 10-minute walks to one 40-minute walk in reducing blood pressure in 20 people with prehypertension.
Prehypertension, in which blood pressure ranges from 120-139 mm Hg over 80-89 mm Hg, is an elevated blood pressure level that will usually progress to high blood pressure. High blood pressure is associated with heart attack, heart failure, kidney failure, stroke and blindness.
The researchers found that while the short walks and long walk decreased the participants' blood pressure by the same amount, the effect lasted for 11 hours after the short walks, compared to seven hours after the long walk.
"We had no idea the short bouts would be better," Janet Wallace, professor in the Department of Kinesiology at the Indiana University School of Health, Physical Education and Recreation, said in a prepared statement. "Most studies found in the literature report the long, continuous session as more effective for many variables."
But these findings may motivate people who cannot seem to fit long bouts of activity in their schedule.
"The biggest problem for most people is that they don't have time," Wallace said. "You might think, 'I don't have the time to go to the gym or work out for 40 minutes, but I might have the time to do 10 minutes here, 10 minutes here and another 10 minutes here.' Four 10-minute walks would be ideal." [标签:content1][标签:content2]
