A pulled hamstring, or any other muscle strain, can take from two to six weeks to heal, depending on the severity of the injury. When a muscle is strained, muscles fibers are stretched or torn.
The more muscle fibers that are torn, the more severe the injury. Significant muscle tears may benefit from surgical repair. For mild hamstring strains, treatment may include a combination of rest, gentle stretching of the thigh and hip, and strengthening exercises to restore the health of the muscle and to limit the risk of recurrence.
Not so fast. Did you consider stretching those muscles that pulled you through your invigorating workout? Understand why stretching matters — and how to stretch correctly.
Benefits of stretching
Most aerobic and strength training programs inherently cause your muscles to contract and flex. That's why regular stretching is a powerful part of any exercise program. Consider this:
* Stretching increases flexibility. Flexible muscles can improve your daily performance. Tasks such as lifting packages, bending to tie your shoes or hurrying to catch a bus become easier and less tiring.
* Stretching improves range of motion of your joints. Good range of motion keeps you in better balance, which will help keep you mobile and less prone to falls — and the related injuries — especially as you age.
* Stretching improves circulation. Stretching increases blood flow to your muscles. Improved circulation can speed recovery after muscle injuries.
* Stretching can relieve stress. Stretching relaxes the tense muscles that often accompany stress.
Some studies indicate that stretching helps prevent athletic injuries as well. However, this finding remains controversial. Other studies don't support stretching as a way to prevent injury.
Stretching essentials
Ready, set, stretch!
* Target major muscle groups. When you're stretching, focus on your calves, thighs, hips, lower back, neck and shoulders. Also stretch muscles and joints that you routinely use at work or play.
* Warm up first. You may hurt yourself if you stretch cold muscles. Warm up by walking while gently pumping your arms, or do a favorite exercise at low intensity for five to 10 minutes. Better yet, stretch after you exercise — when your muscles are warm and more receptive to stretching.
* Pace yourself. It takes time to lengthen tissues safely. Hold each stretch for about 30 seconds, then repeat on the other side. Do each stretch three or four times.
* Don't bounce. Bouncing as you stretch can cause small tears in the muscle. These tears leave scar tissue as the muscle heals, which tightens the muscle even further — making you less flexible and more prone to pain.
* Focus on a pain-free stretch. Expect to feel tension while you're stretching. If it hurts, you've gone too far. Back off to the point where you don't feel any pain, then hold the stretch.
* Relax and breathe freely. Don't hold your breath while you're stretching.
How often to stretch is up to you. As a general rule, stretch whenever you exercise. If you don't exercise regularly, you might want to stretch at least three times a week to maintain flexibility. If you have a problem area, such as tightness in the back of your leg, you might want to stretch more often.
Know when to exercise caution
You can stretch anytime, anywhere — in your home, at work or when you're traveling. If you have a chronic condition or an injury, however, you may need to alter your approach to stretching. For example, if you have a strained muscle, stretching it like usual may cause further harm. Discuss with your doctor or physical therapist the best way to stretch.
