Taking Care of Your Lungs
What aging can bring: Loss of aerobic capacity.
What the research shows: "At any age, you can maximize your aerobic capacity with regular exercise," says Jerome L. Fleg, M.D., a medical officer at the National Heart Lung and Blood Institute. And the fitter you are, the easier it is to perform daily tasks. If you are in good shape, you may need only 50 percent of your aerobic capacity to do something like push a vacuum, depending on your age and sex.
What you can do: Intense activities aren’t necessary; even “walking at a brisk pace on a regular basis can help maintain aerobic capacity in older adults,” says Fleg. (Always consult your physician before starting an exercise program.)
