Baby boomers everywhere are just starting to approach what they thought they never would: old age. Lots of the people born between 1946 and 1964 (the dictionary definition of a boomer) are now eligible for senior citizen discounts at restaurants. Many have grandchildren. And many have sore, creaky joints, the ultimate badge of ageing.
People in this generation are putting a new face on arthritis. According to a report from the National Institutes of Health, ageing baby boomers are at the centre of a growing epidemic. According to the Centres for Disease Control and Prevention, 50 million Americans have arthritis - and by 2030 that number is expected to jump to 67 million.
Such numbers should sound a warning to boomers everywhere. Arthritis or no, now is the time to start taking care of their joints.
Most of all, he intends to keep moving - without overdoing it. Whether it's a long walk with the dogs or a bike ride with his girls, regular exercise will keep his joints flexible for as long as possible. As muscles become stronger and tendons more limber, the pain and stiffness start to fade.
For patients with osteoarthritis, there's another important benefit of exercise. Simply put, regular activity provides lifeblood to the cartilage that cushions joints. Unlike most tissues in the body, cartilage doesn't receive nutrients from the bloodstream. Instead, it gets nourishment from fluid (called synovial fluid) in the joints. When a joint moves, the fluid sloshes around, giving the cartilage a healthy dose of oxygen and other vital substances. As an added bonus, regular exercise encourages the body to make more synovial fluid.
Most baby boomers aren't ready to take their advancing age lying down. Instead, they're running and swimming and shooting jump shots. According to a recent report from the American Academy of Orthopaedic Surgeons, today's boomers are much more active than previous generations. And that's part of the problem.
While a sensible amount exercise offers powerful protection against arthritis, many baby boomers are getting too much of a good thing. Nicholas DiNubile, MD, an orthopaedic surgeon with the Hospital of the University of Pennsylvania, recently summed up the situation at a conference of the American Academy of Orthopaedic Surgeons. "Stiff joints, aching muscles - many of these 'ageing pains' are actually due to overuse. Quite often we find that baby boomers have participated in a sports activity years ago as young adults and think they can resume the same activity in the 40's or 50's without any modifications."
In short, baby boomers often ask too much of their joints. All of that running, jumping, and pounding can easily damage tendons, cartilage, or bone. According to a report in the Annals of Internal Medicine, such injuries often lead to arthritis years down the road. If a person already has arthritis, those sprains and tears and breaks will only add to the pain.
Even if you aren't an athlete, your joints may suffer from normal wear and tear. Doctors perform more than 800,000 knee and hip replacements every year, and that number is expected to grow. Some of the new materials for artificial knees and hips can last longer than the old ones - about 25 to 30 years. The good news is that with joint replacement surgery, many people with severe arthritis can resume a full and active life.
Playing it safe
The American Academy of Orthopaedic Surgeons offers the following tips to help baby boomers avoid injuries:
- Before engaging in vigorous exercise, take the time to stretch your muscles. You should also warm up for three to five minutes with a walk, slow jog, or similar activity.
- Avoid the "weekend warrior" syndrome. Instead of pushing yourself to the limit two days a week, try to get at least 30 minutes of moderate exercise every day.
- Use the 10 percent rule. If you want to boost your activity level (a noble goal), do it just 10 percent at a time. If you normally jog one mile a day, next try going 1.1 miles, not four.
- Invest in good equipment - and yourself. Good shoes and other gear often make the difference between a healthy workout and an injury. If you're taking up a new sport - tennis, for example - consider taking a class to learn the proper techniques to avoid injury.
- Remember, variety is a virtue. A fitness program that combines several different kinds of exercises - including aerobic activity and strength training - will help you keep your joints strong and flexible while reducing the risk of injury, especially from overuse.
- Listen to your body. Your joints will let you know when you've gone too far.
In addition, it's a good idea to keep your weight down. The extra pounds associated with middle age can strain the joints, especially in the knees and hips. Over time, this strain may lead to arthritis. The good news is that even a small reduction in your waistline can lead to a big reduction in your risk. A study published in the Annals of Internal Medicine found that women who lost an average of 11 pounds over 10 years cut their risk of osteoarthritis in the knee by half.
