Are you guilty of skipping that pre- or post-workout stretch?

You may want to make space in your exercise routine to keep your muscles and joints working their best. Some research shows that stretching helps with flexibility and may reduce pain and injuries. It also offers several health benefits for those over age 65.

Confusion keeps some of us from prioritizing muscle stretches as part of a fitness plan. 何时以及如何伸展?

“Stretching before and after a workout improves range of motion and decreases the risk of tearing of muscles and sprains,博士解释道。. Kelly Lowther of Miramont Wellness Centers.

There are three common types of stretching: dynamic, 静态, and proprioceptive neuromuscular facilitation (PNF), and all of these are best performed at different times.

Dynamic stretching is best done before a workout. It warms up the tissues and actively moves muscles and joints through their full range of motion. 通过动态拉伸, 比如躯干旋转和步行弓步, you’re moving the muscle rather than holding it.

“Flexibility and strength are both important as we grow older,” says Lowther. “Doing slow, deliberate movements helps with both.”

静态拉伸, 单独或与同伴一起表演的, involves slowly lengthening the target muscle until the stretch reflex kicks in, and then holding it for about 15 to 30 seconds until the stretch lessens. Repeat, gently building up to a deeper stretch with each repetition. It’s normal to feel some mild discomfort, but back off if you feel any pain, Lowther advises.

静态拉伸 is best performed after a workout, 当身体足够暖和时, 不建议在锻炼前服用.

适合老年人, 保持静态拉伸的时间长一点, 30 - 60秒, can help boost range of motion and flexibility — and provides other benefits as well. One study showed that regularly stretching the lower part of your body, 从臀部到脚趾, 能降低65岁以上成年人跌倒的风险吗.

PNF伸展虽然, developed by a doctor and two physical therapists in the mid-20th century to help polio patients with rehabilitation, has gained popularity in the last few decades. The technique focuses on improving range of motion — the maximum amount a joint can move — and is best done before light- to medium-intensity exercises. It should not be done before high-intensity workouts such as weight lifting or sprinting.

PNF involves the individual or a partner actively lengthening the target muscle and following this with contraction, 或紧张, 大约6秒. The partner then does another deeper stretch on the individual. An example is a hamstring stretch where you lie on your back and a partner lifts one leg up and back, keeping the knee straight for 7 to 10 seconds. Then you push the leg back against your partner for 7 to 15 seconds, which contracts the muscle. 放松几秒钟，然后重复. 没有合作伙伴? You can achieve the same thing with a band or other equipment for resistance.

Finally, make sure you avoid overstretching. 根据洛瑟的说法, stretching should be done slowly and deliberately, and never to the point of forcing increased range of motion.

Working a stretch routine into your day-to-day activities can have several benefits. The best part is that you can do it whenever you want, wherever you want, and it’s free!
