As a guy in his late 60's who didn't have time or even thought about going to the gym to get fit, I decided to do a little research about how much time an older guy should spend exerting himself a little more than by just tapping a keyboard all day long.
A new study shows that small bouts of light physical activity are enough to increase lifespan in older men.
In the report, researchers looked at about 1,180 men — average age, 78 — who agreed to wear devices that measured their movements for seven days. They were followed for about five years. The researchers found that the overall volume of exercise, not necessarily how long or how hard someone exercised in a session, mattered most for longevity.
Every 30 minutes of light intensity activity per day — like going on a walk or gardening — was linked to a 17% lower risk of early death in the study. Moderate-to-vigorous physical activity had an even stronger link to a longer life: doing it was associated with a 33% reduction in death risk for every 30 minutes of exercise. However, the fact that light exercise still appeared to have a notable longevity benefit is important, the study authors write.
