FRIDAY, Jan. 16, 2004 (HealthDayNews) -- It's one thing to have stomach muscles that resemble a six-pack when you're younger, but how about being able to carry a six-pack from the car to the house when you're 75?
The latter is the goal of exercise for older people, says an exercise professional who specializes in fitness for seniors.
"The image of fitness is a ripped bodybuilder, but when you're talking about older adults, they just want to be active and physically healthy," says Colin Milner, head of the International Council on Active Aging, a trade association of more than 3,500 organizations that specializes in senior fitness.
And regular exercise can keep them that way long into old age, he says.
"Many of the chronic health conditions we experience as we age come from disuse rather than aging, and exercise can retard the onset of many of those conditions," he says.
For example, consider this: Beginning at age 50, people begin to lose 12 percent of their muscle strength and 6 percent of their muscle mass every decade, says University of Maryland kinesiologist Ben Hurley.
But weight training can reverse these effects significantly -- two to three months of thrice-weekly weight training can increase muscle strength and mass by a third, making up for up to three decades of loss of muscle strength and muscle mass, he says.
"You can't completely do away with aging effects, but you can delay the onset of the loss of muscle strength and mass by exercise," he says.
Milner says it can be difficult for older people interested in exercise to find a way to start a program because most exercise facilities and programs are aimed at younger people.
"While many organizations are trying -- like YMCAs, hospital wellness centers and retirement communities with trained staffs -- the vast majority of health centers are still very youth-oriented," he says. "The fitness industry has portrayed exercise as an activity for younger people, and the message turns off the elderly."
With that in mind, Milner's organization recommends some guidelines to help seniors increase their physical activity.
"We're all looking for the fountain of youth," says Milner, "But the closest thing may be physical activity."
