What causes an overuse injury in a runner?
Overuse injury in a runner most often occurs because of a training error (running too far, too fast, too soon). With every mile that is run, the feet must absorb 110 tons of energy. Therefore, it is not surprising that up to 70% of runners develop an injury every year.
How can overuse injury be prevented?
You can decrease your risk of injury by following these recommendations :
- Do not increase running mileage by more than 10% per week.
- Do not run more than 45 miles per week. There is very little evidence that running more than 45 miles per week improves your performance, but there is a great deal of evidence that running more than 45 miles per week increases your risk for an overuse injury.
- Do not run on slanted or uneven surfaces. The best running surface is soft, flat terrain.
- Do not "run through pain." Pain is a sign that should not be ignored, since it indicates that something is wrong.
- If you do have pain when you run, place ice on the area and rest for 2 or 3 days. If the pain continues for 1 week, see your doctor.
- Follow hard training or running days with easy days.
- Change your running shoes every 500 miles. After this distance shoes lose their ability to absorb the shock of running.
What about orthotics to reduce the chance of injury?
Orthotics are inserts that are placed in shoes to correct bad alignment between the foot and the lower leg. You will probably need orthotics if you have a problem called pronation, which means that the inside of the foot turns in. If you have bad alignment but no pain with running and you do not suffer from repeated injuries, you probably do not need orthotics. Many world class athletes with bad alignment do not wear orthotics. However, your doctor may suggest orthotics if you have bad alignment and become injured and do not get better with other measures, such as rest, ice application and cross-training.
What exercises help prevent or treat injuries?
Before and after a run, perform specific stretching exercises. See the pictures on the next pages that show stretching exercises. These exercises may also be part of your recovery from an injury. With each exercise, hold the stretch for at least 15 seconds, and do not bounce. Stretch until you feel tension but not pain.
If you do develop an injury, your doctor may suggest particular strengthening exercises. See the pictures on pages 3 and 4 showing strengthening exercises. Every day you should do 3 sets of each exercise, with 10 repetitions in each set. For the exercises that involve straight-leg raises, you will want to add ankle weights as the exercises become easier for you to do. These exercises may also be done as part of your overall exercise program.
Hamstring stretch
 |
Sit with your injured leg straight and your other leg bent. With your back straight and your head up, slowly lean forward at your waist. You should feel the stretch along the underside of your thigh. Hold the stretch for 10 to 15 seconds. Repeat the stretch 6 to 8 times. This stretching exercise may be helpful for patellofemoral syndrome, patellar tendinitis and hamstring strain.
|
Iliotibial band stretch
 |
Sit with your injured leg bent and crossed over your straightened opposite leg. Twist at your waist away from your injured leg, and slowly pull your injured leg across your chest. You should feel the stretch along the side of your hip. Hold the stretch for 10 to 15 seconds. Repeat the stretch 6 to 8 times. This stretching exercise may be helpful for iliotibial band syndrome and adductor strain.
|
Groin stretch
 |
Sit with your feet together, your
back straight, your head up, and your elbows
on the inside of your knees. Then slowly push
down on the inside of your knees with your elbows.
You should feel the stretch along the inside
of your thighs. Hold the stretch for 10 to 15
seconds. Repeat the stretch 6 to 8 times. This
stretching exercise may be helpful for adductor
strain.
|
Quadriceps stretch
 |
Stand straight with your injured
leg bent. Grasp the foot of your injured leg
with your hand and slowly pull your heel to
your buttocks. You should feel the stretch in
the front of your thigh. Hold the stretch for
10 to 15 seconds. Repeat the stretch 6 to 8
times. This stretching exercise may be helpful
for patellofemoral syndrome, iliotibial band
syndrome and patellar tendinitis.
|
Calf stretch
 |
Stand with your hands against a wall and your injured leg behind your other leg. With your injured leg straight, your heel flat on the floor and your foot pointed straight ahead, lean slowly forward, bending the other leg. You should feel the stretch in the middle of your calf. Hold the stretch for 10 to 15 seconds. Repeat the stretch 6 to 8 times. This stretching exercise may be helpful for Achilles tendinitis, plantar fasciitis and calcaneal apophysitis.
|
Plantar fascia stretch
 |
Stand straight with your hands
against a wall and your injured leg slightly
behind your other leg. Keeping your heels flat
on the floor, slowly bend both knees. You should
feel the stretch in the lower part of your leg.
Hold the stretch for 10 to 15 seconds. Repeat
the stretch 6 to 8 times. This stretching exercise
may be helpful for plantar fasciitis, Achilles
tendinitis and calcaneal apophysitis.

Strengthening exercises
 |
Lie down with your upper body
supported on your elbows. Tighten the top of
the thigh muscle of your injured leg. Raise
your leg on a count of 4, hold for a 2 count
and then lower the leg on a 4 count. Relax your
thigh muscles. Then tighten the thigh and repeat.
Do 3 sets of 10 repetitions each day. Once your
leg gains strength, do the exercise with weights
on your ankle. This strengthening exercise may
be particularly helpful for patellofemoral syndrome
or patellar tendinitis.
|
Straight-leg raise
 |
Lie on your unaffected side, tighten
the thigh muscle of your injured leg and then
slowly raise the leg off the floor. Hold the
leg up for a 2 count, and lower it on a 4 count.
Relax your muscles. Then tighten the thigh and
repeat. Do 3 sets of 10 repetitions each day.
Once your leg gains strength, do the exercise
with weights on your ankle. This strengthening
exercise may be helpful for iliotibial band
syndrome.
|
Straight-leg raise
 |
Lie on your affected side with
the unaffected leg crossed over the knee of
your injured leg. Tighten your thigh muscles
and raise the injured leg about 6 to 8 inches
off the floor. Hold for 2 seconds, and then
slowly lower your leg. Relax the muscles. Then
tighten the thigh and repeat. Do 3 sets of 10
repetitions each day. Once your leg gains strength,
do the exercise with weights on your ankle.
This strengthening exercise may be helpful for
adductor strain.

Standing wall slide
 |
Stand with your back against the
wall and your feet 6 to 8 inches away from the
wall. Slowly lower your back and hips about
one-third of the way down the wall. Hold the
position for about 10 seconds or until you feel
that the tops of your thigh muscles are becoming
tired. Straighten up and repeat. Perform 10
repetitions each day. This strengthening exercise
may be helpful for patellofemoral syndrome or
patellar tendinitis.
|
Straight-leg raise
 |
Lie on your stomach. Tighten your
thigh muscles and slowly raise your injured
leg off the floor on a 4 count. Hold the leg
up for a 2 count, and then lower the leg on
a 4 count. Relax your thigh muscles. Tighten
the thigh and repeat. Do 3 sets of 10 repetitions
each day. Once your leg gains strength, do the
exercise with weights on your ankle. This strengthening
exercise may be helpful for hamstring strain.
|
Lateral step-ups
 |
Stand with your injured leg on
a stair or platform that is 4 to 6 inches high.
Slowly lower the other leg, striking the heel
on the floor. Straighten the knee of the injured
leg, allowing the foot of the other leg to raise
off the floor. Repeat. Do 3 sets of 10 repetitions
each day. This strengthening exercise may be
helpful for patellofemoral syndrome and patellar
tendinitis.
