Studies about the benefits of stretching have had mixed results. Some show that stretching helps. Other studies show that stretching before or after exercise has little to no benefit.
Some research shows that stretching doesn't reduce muscle soreness after exercise, and other studies show that static stretching performed immediately before a sprint event may slightly worsen performance.
Stretching can help improve flexibility, and, consequently, range of motion about your joints. Better flexibility may:
Stretching also increases blood flow to the muscle. You may learn to enjoy the ritual of stretching before or after hitting the trail, ballet floor or soccer field.
Before you plunge into stretching, make sure you do it safely and effectively. While you can stretch anytime, anywhere, be sure to use proper technique. Stretching incorrectly can actually do more harm than good.
Use these tips to keep stretching safe:
Don't consider stretching a warmup. You may hurt yourself if you stretch cold muscles. Before stretching, warm up with light walking, jogging or biking at low intensity for five to 10 minutes. Even better, stretch after your workout when your muscles are warm.
Consider skipping stretching before an intense activity, such as sprinting or track and field activities. Some research suggests that pre-event stretching may actually decrease performance. Research has also shown that stretching immediately before an event weakens hamstring strength.
Instead of static stretching, try performing a "dynamic warmup." A dynamic warm-up involves performing movements similar to those in your sport or physical activity at a low level, then gradually increasing the speed and intensity as you warm up.
Focus on major muscle groups. Concentrate your stretches on major muscle groups such as your calves, thighs, hips, lower back, neck and shoulders. Make sure that you stretch both sides.
Also stretch muscles and joints that you routinely use.
Keep up with your stretching. Stretching can be time-consuming. But you can achieve the most benefits by stretching regularly, at least two to three times a week.
Skipping regular stretching means you risk losing the potential benefits. For instance, if stretching helped you increase your range of motion, your range of motion may decrease again if you stop stretching.
Bring movement into your stretching. Gentle movements, such as those in tai chi or yoga, can help you be more flexible in specific movements. These types of exercises can also help reduce falls in seniors.
Remember the "dynamic warmup:" If you're going to perform a specific activity, such as a kick in martial arts or kicking a soccer ball, start out slowly and at low intensity to get your muscles used to it. Then speed up gradually.
You might need to approach stretching with caution. If you have a chronic condition or an injury, you might need to adjust your stretching techniques. For example, if you already have a strained muscle, stretching it may cause further harm.
Remember that stretching doesn't mean you can't get injured. Stretching, for instance, won't prevent an overuse injury. Talk to your doctor or physical therapist about the most appropriate way to stretch if you have any health concerns.
