On many days, reading the sports page can feel like reading The New England Journal of Medicine. Exercise puts the body under stress, and stress can lead to injury. It's all in a day's work for competitive athletes, but ordinary guys get hurt, too. The good news is that you can prevent many exercise-induced injuries. And even when prevention fails, you can handle common problems on your own.
A study of 6,313 adults who exercised regularly found that 21% developed an exercise-related injury during the course of a year. Two-thirds involved the legs; the knee was the most frequently injured joint.
It sounds grim, but it's not. First, injuries are much more common with intense exercise and competitive sports than with moderate exercise for health. Second, people who exercise actually have a lower long-term risk of disability than sedentary people. A 13-year study of 370 exercisers ages 50 to 72, for example, found that exercise was linked to less risk of disability and a lower death rate, even among older folks who ran, which is a high-impact activity.
Here are a few key tips for preventing injuries when you exercise:
If you can't prevent injury early detection is the next line of defense. A bit of soreness and stiffness is normal, but pain, swelling, diminished strength or mobility, and discoloration of the skin is not. Spot small problems before they become big ones. If your problem seems small, treat it yourself. But if you don't improve — or if you have a major injury — get expert help.
Treat minor injuries yourself using a 5-point program called PRICE: Protection, Rest, Ice, Compression and Elevation.
PRICE is the key to the early management of most kinds of injuries. But you may also need medication for pain or inflammation. Acetaminophen (Tylenol and other brands) may be the best choice for the first day because it will reduce pain without increasing bleeding. After the first day or two, consider aspirin or other non-steroidal anti-inflammatory (NSAIDs), such as ibuprofen (Advil and other brands) or naproxen (Aleve). These fight inflammation as well as pain. NSAIDs can irritate the stomach; take them with milk or food, and always follow directions for use.
The PRICE program relies on using cold first, and then heat along with anti-inflammatory medications or pain relievers if needed. Instead of an ice pack or warm pack, you can rub in an ointment that will make your tissues feel cool or warm. And you can also buy liniments, gels and ointments that contain anti-inflammatory medications. Topical anti-inflammatory are available without a prescription. They are much safer than oral anti-inflammatory medications, but they're also less effective.
Your pain is gone and your swelling is down — but your treatment is not yet over. You need to plan your rehabilitation and return to exercise with the same care that you used to treat your injury. As a rule of thumb, give yourself two days of rehab for each day of inactivity.
Start with gentle range of motion exercises. If your injury involves your leg or foot, go slowly as you resume weight-bearing. When you are ready, add resistance training (calisthenics, light weights or equipment such as Cybex or Nautilus) to build back muscle tissue. If all goes well, you can be stronger than before your injury. This can help reduce your risk of re-injury.
Stretching exercises can improve your flexibility. Use heat or massage to warm up your injured tissues before you start your rehab exercises. Afterwards, apply ice to the area to reduce inflammation. Aspirin or other NSAIDs may also help your rehab program.
You can manage many injuries yourself, but don't be stubborn. If you have a major injury — or if your nagging woes don't clear up — get help. An experienced exercise buddy who has "been there, done that" may be all the help you need. Primary care physicians can handle many exercise-induced problems. But more difficult issues require orthopedists, physical therapists and sports podiatrists. These specialists usually practice at sports medicine clinics.
The most dangerous thing about exercise is not doing it. Injuries do happen, but don't let the possibility of getting injured become an excuse for staying on the couch. Instead, follow the simple steps that will reduce your risk of exercise-induced injuries, become able to spot problems early, learn how to handle minor injuries on your own, and be prepared to get help when you need it. It's easy to overcome simple injuries — but very difficult to treat the major illnesses that may stem from lack of exercise — heart disease.
