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.
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 US Health and Human Services Department.
But you need not — indeed should not — wait for the government. Even if you have a chronic health problem or physical limitation, there are safe ways to improve fitness and well-being. Any delay can increase the risk of injury and make it harder to recoup your losses.
UNFAMILIARITY AND FEAR
Miriam Nelson, director of the John Hancock Center for Physical Activity and Nutrition at Tufts University in Boston and lead author of the new recommendations, observed last fall in The Journal on Active Aging that “with every increasing decade of age, people become less and less active.”
“But,” Nelson said, “the evidence shows that with every increasing decade, exercise becomes more important in terms of quality of life, independence and having a full life. So as of now, Americans are not on the right path.”
Jim Concotelli of the Horizon Bay Senior Communities in Tampa, who oversees fitness and wellness program development for communities for the elderly in several states, noted this year in The Journal on Active Aging that many older Americans were unfamiliar with exercise activities and feared that they would cause injury and pain, especially if they have arthritis or other chronic problems. Yet by strengthening muscles, he said, they can improve joints and bones and function with less pain and less risk of injury.
The key is start slowly and build gradually. Most important is simply to start — now — perhaps under the guidance of a fitness professional or by creating a program based on the guidelines outlined here.
Although medical clearance may not be necessary for everyone for the moderate level of activity suggested, those with a known or possible problem would be wise to consult a doctor. And a few sessions with a trainer can help assure that the exercises are being done correctly and not likely to cause injury.
Until recently, physical activity recommendations for all ages have emphasized aerobics, or cardiovascular conditioning, through moderate to vigorous activities like brisk walking, cycling, lap swimming or jogging for half an hour a day five or more days a week. For those unable to do 30 minutes at a time, the activities can be broken up into three 10-minute intervals a day. If you have long been sedentary, start with even shorter intervals.
MORE IS BETTER
For people who prefer indoor workouts, a treadmill, cross-trainer, step machine or exercise bike can provide excellent aerobic training for the heart, lungs and circulation. Those unable to do weight-bearing exercise might try swimming or water aerobics. Keep in mind that 30 minutes a day of aerobic activity five days a week is the minimum recommendation. More is better and can reduce the risk of chronic disease related to inactivity.
