運動能延長壽命 Exercise Lengthens Life Regardless of Weight
A little exercise
each week can lead to big gains in life expectancy. And that’s true regardless
of your current weight, according to a new review study that included more than
650,000 people.
The World Health
Organization recommends two-and-a-half to five hours of brisk walking per week,
or less time spent at a more vigorous activity. People who got the full
recommended amount of exercise saw an average 3.4-year
gain in life expectancy.
People who got half as much exercise still lived an
average 1.8 years longer. The
findings are in the journal PLoS Medicine. [Steven C. Moore et al., Leisure
Time Physical Activity of Moderate to Vigorous Intensity and Mortality: A large
pooled cohort analysis]
In fact, exercise
was a bigger factor than body weight in many cases. People who were normal weight but
were inactive actually lived an average of 3.1
fewer years(若是改為years fewer?) than obese people who kept up high levels of
activity.
Finding time to
exercise can be tough.
Maybe look at it this way. There are almost 9,000 hours in a year. Five hours a week is
260 hours a year—to get an extra 30,000 hours of
life. Do
the math. While you take a walk.
