Running Injury? Maybe your doing it all wrong.
If exercise were a medication, it’d be a blockbuster. That’s because exercise has been linked to a long list of remarkable health benefits and just about everyone can take advantage of them. That’s why your doctor will probably recommend that you get more exercise—or commend you for doing so already.
What can exercise do for you?
If you aren’t particularly active and begin a regular and sustained exercise program, here are just some of the health benefits you might experience:
- Loss of excess weight
- Improved energy and stamina
- Lower cholesterol and blood pressure
- Lower average blood sugar
- Increased muscle mass, strength, and balance
- Increased bone strength
- A lower risk of certain cancers
- Improved mood and sleep
The magnitude of the benefit and its long-term impact on your health and longevity vary from person to person because each of us starts from a different place and has different risk factors for disease. But for most folks, more exercise is generally better.
The downside of exercise
As with many other health-promoting treatments, there are potential “side effects.” Exercise takes time. It can be expensive (but doesn’t have to be). And then there are the exercise-related injuries to consider. Depending on the type of exercise you prefer, injuries may be quite common. For example, up to 75% of runners get injured each year. It’s enough to make you wonder if what you’re doing is really good for you!
A new study of how runners run
A new study compared runners who reported significant running injuries to those who didn’t, in order to understand what the injury-free group was doing differently. If you’re a runner, the findings could make you change your technique.
Researchers enrolled 249 women who ran at least 20 miles/week and asked them to keep a diary recording their injuries each month. This went on for two years. About 60% of the runners described injuries, most of which were severe enough to require medical evaluation.
Then the women were asked to run over a “force plate,” a device that recorded the force during that ¼ of a second when the foot strikes the ground. Those who reported having suffered significant injuries landed harder than those who had been injury free.
These different running patterns might explain why some runners seem to glide effortlessly. Chances are they land more softly and put less stress on their bodies with each step. Although most runners land first with their heels, past research has suggested that landing farther forward may lessen impact and allow the foot and ankle to absorb more force with each step.
This study raises some interesting questions, including:
Are running injuries actually caused by the amount of force generated with each step? Or, is there something else (such as stride length or body posture while running) that explains this connection?
- Is the higher force of impact a cause of injuries or the result? In other words, maybe runners land harder when there is something amiss, perhaps a knee or hip problem, of which they are not yet aware.
- Would the same results be found if men were included in the study? What about people who run less than 20 miles/week? Or far more?
- How easy is it to land more softly while running? And, would this actually decrease injuries?
- Would landing farther forward on the foot (rather than on the heel) be better?
Should you change how you run?
With more research, we might soon have answers to these questions. But right now, we may not have enough information to make a strong recommendation that all runners try to change how hard they land. But, if future studies confirm the findings of this latest research, we’ll need to learn and teach better running technique. And perhaps we’ll need to rethink the wisdom of those highly cushioned heels in our running shoes that all but invite heel-first running.
In the meantime, don’t use this new report as an excuse not to run or pursue other exercise. Find activities that you enjoy and that you can perform regularly without injury. Whatever your choice of exercise, remember this: it’s usually better to keep moving than not.
Tips to reduce your risk of exercise-related injuries
- Stretch well before, after and, if possible, during exercise.
- Use appropriate protective gear.
- Cross-train. Reduce the chances of overusing or injuring any one group of muscles by doing different activities that use different muscle groups.
- Resist the temptation to do too much too soon. If you are starting from a state of poor conditioning, start slow and work up very gradually.
- Listen to your body’s signals. If you are “under the weather,” take a day off. Don’t exercise if you have a fever. If your periods have stopped, you may be exercising too much and an evaluation with your doctor is warranted. Persistent pain is not normal and should prompt a re-evaluation of your exercise program.
- Consider backing off on the intensity of your exercise. If you are exercising for your health (and not to win competitions), there is evidence that low to moderate exercise several times a week may be better for you than high intensity exercise every day.
- Change your program to lower-impact activities, such as an exercise bike instead of running, especially if you are over 30; as we age, our muscles, bones, and joints become less forgiving of repetitive or forceful impact.
- Be careful. Pay attention to general safety and the “rules of the road” if you are walking, jogging, biking, or otherwise sharing the road with automobiles, especially at night.
