Fit, Not Frail: Exercise as a Tonic for Aging

“Fact: Every hour of every day, 330 Americans turn 60.
Fact: By 2030, one in five Americans will be older than 65.
Fact: The number of people over 100 doubles every decade.
Fact: As they age, people lose muscle mass and strength, flexibility and bone.
Fact: The resulting frailty leads to a loss of mobility and independence.”

“The last two facts may sound discouraging. But they can be countered by another. Regular participation in aerobics, strength training and balance and flexibility exercises can delay and may even prevent a life-limiting loss of physical abilities into one’s 90s and beyond. The last two facts may sound discouraging. But they can be countered by another. Regular participation in aerobics, strength training and balance and flexibility exercises can delay and may even prevent a life-limiting loss of physical abilities into one’s 90s and beyond. This last fact has given rise to a new group of professionals who specialize in what they call ‘active aging’ and an updated series of physical activity recommendations for older adults from the American Heart Association and the American College of Sports Medicine. These recommendations are expected to match new federal activity guidelines due in October from the United States Health and Human Services Department.”
