'Weekend Warriors' Shown to Lower Their Risk of Life-threatening Illnesses

So-called "weekend warriors" — people who exercise one or two days a week — may reduce their risk of dying over roughly the next decade nearly as much as people who work out more often, according to a new study.
Previous guidelines from the World Health Organization recommend that the average adult engage in moderate-intensity physical activity for at least 150 minutes per week — or vigorous activity for 75 minutes per week — in order to reduce the risks of dying from causes such as heart disease and cancer.
However, there is no consensus on how best to distribute the exercise time to achieve the greatest health benefits.
In the study published in the journal JAMA Internal Medicine, researchers looked to address that question.
The study found that "weekend warriors" reduced their risk of dying by 30 percent compared to those who engaged in little or no physical activity. People who exercised more often throughout the week lowered their risk by 35 percent.
For cancer deaths, the risk reductions were 18 percent in “weekend warriors” and 21 percent in those who were regularly active.
And for cardiovascular disease, there was a 41 percent lower risk of heart disease in people who were physically active one or two days a week and those who engaged in physical exertion more regularly, compared to so-called "couch potatoes."
The study, conducted during a 9-year period, was based on the self-reported exercise habits and health examinations of more than 63,000 adults in England and Scotland. The information was linked to mortality records.
Exercises included participating in sports or taking a brisk walk.
Emmanuel Stamatakis from the University of Sydney in Australia, one of the study's senior authors, found it "very encouraging" that even people who exercised as little as one or two times a week appear to lower their risk of obesity, health problems and death.
But for peak health, Stamatakis said, more exercise is better.
Physical activity has been associated with a reduction in a number of risk factors for disease, including lowering cholesterol, controlling weight and reducing blood pressure.
世界衛生組織(World Health Organization, WHO)在之前所頒布的指南中建議，一般成年人每週應從事(engage in)至少150分鐘中高強度的體能活動，或75分鐘的高強度運動(vigorous activity)，如此能減少因心臟病及癌症等疾病而死亡的風險。
研究人員著眼於處理(address)這個問題，其研究發表在《美國醫學會雜誌：內科醫學》(JAMA Internal Medicine)期刊。

而在心血管疾病(cardiovascular disease)方面，與所謂不愛動的「沙發馬鈴薯(couch potato)」相比，一週當中運動一到兩天的人，以及會更規律地從事耗費體力的運動(physical exertion)的人，其罹患心臟相關疾病的風險減少了41%。
研究中所指的運動包含了參加體育運動，或是快步行走(take a brisk walk)等。
