Easing Age Gap Through Regular Exercise

Fri, 14 Nov 2008

OLDER adults may have to work harder than young people to perform the same physical activity, but regular exercise may close that age gap, research findings suggests.

In a study comparing sedentary adults in their 60s and 70s with those in their 20s and 30s, researchers found that older men and women had to use much more oxygen to walk at the same speed as their younger counterparts.

But that was before they went through a six-month exercise programme. After taking up walking or jogging, biking and stretching, the senior study participants reversed their loss of exercise `efficiency'.

Exercise efficiency refers to how much energy the body expends to perform a given activity.
