Navratilova and others discuss staying fit and healthy at age 20 vs. age 60


By Gabriella Boston, Published: June 24

One sneaker fits all.
According to government recommendations, you should do at least 21 / hours of moderate aerobic activity per week and twice-weekly sessions of strength training to improve your health, no matter your age.
But don’t physical fitness needs change as we grow older?
Not that much, it turns out.
Todd Miller, an associate professor in the Department of Exercise Science at George Washington University, says whether you’re 20 years old or 60, you will need a combination of cardio and strength training to keep your heart and muscles in good shape and your weight under control.
The one difference may be that strength training becomes more crucial for everyday functional fitness as you get older. “A big issue as you age is the risk of falling. And strength training that builds muscle power helps prevent falls,” he says.
“People should do a combination of both cardio and strength” to meet those fitness goals, he says, but in general he sees an “overemphasis on cardio and underemphasis on strength.”
The challenge, Miller says, is not deciding whether fitness needs are age-specific. It’s getting people to do what they should do, at any age, to stay healthy and fit. “The problem is not the exercise or the type of exercise; it’s the adherence or the lack of adherence to exercise that is the main issue,” he says.
Only about 20 percent of Americans follow the government recommendations.
As you try to figure out a regime that keeps you healthy, here’s some advice from three people — Miller, a trainer and tennis great Martina Navratilova — that may help you, whether you’re 20 or 60.
The professional athlete
“As we age, we should exercise more often but for shorter periods of time,” says Navratilova, 56, who writes a health and fitness column for AARP.
“And mix up your routine. Do strength, cardio, yoga. Do what feels good in the body, go easy on the joints,” she says.
That’s actually pretty much in line with government recommendations, which say, “We know 150 minutes each week sounds like a lot of time, but you don’t have to do it all at once. Not only is it best to spread your activity out during the week, but you can break it up into small chunks of time during the day. As long as you’re doing your activity at a moderate or vigorous effort for at least 10 minutes at a time,” says the Center for Disease Control and Prevention, which recommends “a 10-minute brisk walk, 3 times a day, 5 days a week. This will give you a total of 150 minutes of moderate-intensity activity.”
Navratilova says that when she was in her 20s, she worked out six hours a day and could do 70-pound triceps presses. No more. “Daily exercise? I don’t do anything daily except eat and sleep,” she jokes. “But I do think if you can do functional fitness [exercises designed to help someone better handle daily tasks] for an hour a day, that is great,” she says. But for aging bodies, she adds, don’t overdo it. “Be nice to yourself and listen to your body.”
Navratilova says she recently began running again after a hiatus. “Nothing feels better than when you can run,” she says. “But every day? Absolutely not. It’s hard on your joints.”
Now living in Miami, she mixes it up by adding bicycling and paddleboarding to her running and tennis cardio regimen.
The trainer
Mike Fantigrassi, a trainer at the National Academy of Sport Medicine in Chandler, Ariz., says he makes balance and flexibility exercises a regular part of sessions with clients, but it’s different for younger and older people.
“If we have 60 minutes, we would do about five minutes of flexibility for someone in their 20s or 30s,” he says. “For someone 65 or older, we might do up to 15 minutes of flexibility.” It’s not that the 20- or 30-year old should go completely without stretching (particularly of the postural muscles — chest, core, neck and shoulders — that get tight from sitting at a desk all day) or working on balance, he says. But younger bodies, generally speaking, are naturally looser than older ones and have not been subjected to as much wear and tear.
So when a 20-year-old reaches down to pick something up off the floor, he probably won’t notice anything, but a 60-year-old may feel a tight hamstring. “But even a teenager who never does any flexibility work might get reduced joint flexibility eventually,” he adds.
Fantigrassi, who is 40, adds that the ability to generate muscle power suffers as we age, but we can slow the process down with such exercises as jumps — from foot to foot, or up and down from a bench or box. Eventually you’re going to lose your basketball jump shot, but you can keep it alive longer by training the leg muscles that generate power.
The researcher
Miller, 45, says that while building stronger muscles is protective for older people, strength training is important for everyone.
People begin to lose muscle mass and strength in their 30s, which slows metabolism. WebMD.com says that “each extra pound of muscle you carry can burn up to 50 additional calories [per day] just to maintain itself — and with no effort on your part.” Others, however, suggest that the muscle effect is probably much smaller.
Lifting weights can counteract muscle loss. Of course, you still may not be able to lift as much weight in your 60s as you could in your 20s, but you can slow muscle loss, which otherwise can decline by 5 percent per decade after age 30.
“The only difference between 20 and 60 is that you might be lifting less weight at 60. But the exercises themselves shouldn’t change unless you have an injury, but that isn’t age related,” says Miller.
Strength training will also improve bone density, says Miller, who advocates the type of strength exercises where the feet are planted on the floor and generate force into the spine. It could be a regular squat. It could be a squat with dumbbells in your hands, resting on your shoulders. It could be one of those squat machines with padding on top of the shoulders.
Given that most Americans gain roughly a pound per year starting in their 20s, it’s important at all ages to have cardio workouts in your week.
“If running feels good, then run,” Miller says. Just make sure it feels okay in your joints, whether you’re 20 or 60. “For me, it hurts, so I don’t do it.” In such cases, a treadmill or bike may be a better bet, he says. Whatever you choose, the point is to get regular exercise no matter what age you are.

How an Athlete Ages

This month, since I’m turning 50, I’m trying to prove that birthdays—even milestone ones like this one—are the most inconsequential change of all. It’s what’s in our heads rather than in our bodies that makes the real difference. But that’s not to say our bodies don’t undergo some pretty significant changes as we approach the Metamucil Years. In fact, here’s what happens to three of the biggest components of athletic performance:

Strength

According to research conducted at the University of Nevada at Las Vegas (how did I not apply there?), the average guy’s ability to bench-press an 80-pound barbell drops from 23 reps at age 18-25 to 6 reps at age 65-plus. That means the average young man is nearly three times as strong as the typical gray-hair. Indeed, strength declines more precipitously with age than any other fitness component.

Cardiovascular fitness

Generally, the lower your heart rate during exercise, the stronger your ticker and the fitter you are. In another UNLV experiment, men between the ages of 18 and 25 stepped on and off a foot-high bench for 3 consecutive minutes. Their average heart rate was 102 beats per minute. But when the same test was given to guys age 46 to 55, their average pulse was 113 bpm. The simple act of getting older had eroded about 10 percent of their fitness.

Flexibility

Adults are at their Gumby peaks between ages 18 and 25. At that time, if you sit on the floor with legs extended and reach forward, you’ll generally be able to stretch 16 inches, or about an inch past your toes. But if a 65-year-old guy does the same thing, he’ll only get about 10 inches out (and you’ll probably have to help him up). Nearly half of his flexibility will be gone.

Your Action Plan

Getting depressed? Fighting the urge to Google the Jazzy Power Chair? Don’t sweat it. Although all these changes are happening inside you right now, you can slow, stop or even reverse their progression. That’s something science didn’t fully understand or appreciate even 20 years ago, when it was thought that much of this was irreconcilable. Now we know that with proper training and smart living, anyone can reclaim a good chunk of that 18 to 25 prime time.

For real-life proof of this, consider a study currently being conducted by Athletes’ Performance in Gulf Breeze, Florida. Since January, researchers there have been working with members of the Pensacola Fire Department in an attempt to determine the best way to train “occupational athletes,” or people who must be physically fit to do their jobs. Although the study still has a few months to run, researcher and kinesiologist David Frost says he’s already convinced that the physical effects of aging are surmountable obstacles.

“We’re dealing with firefighters from age 20 to 57,” he explains. “Initially, some of the older guys were hesitant about getting involved and training hard for 12 weeks. They didn’t think they were as strong, as flexible or as cardiovascularly fit as the younger, more ripped guys. And they were afraid of getting injured. But now they can do everything the younger guys can. It was just their confidence that was holding them back. They didn’t even require more rest.”

Frost hopes that recreational athletes will eventually shift from narrow, sports-specific training to a much broader style of conditioning, like the type of movement workouts Athletes’ Performance advocates. Instead of limiting your training to your preferred sport, be it running, strength training, softball or triathlons, he says the key to lifelong fitness is broadening your mindset. “Instead of training for a sport, train for life,” he says. “Instead of going to the gym to get a great workout, work out so you can enjoy a great life.”

For the specifics of how to do this, watch for my next blog, “The Age-Defying Workout.” Among others, I’ll be talking to strength-and-conditioning coach, Ken Croner, of Athletes’ Performance, who worked with ageless Packer and Jet vet, Brett Favre.
