Stretch Your Body, Stretch Your Lifespan

/in /by

“Stretching reduces your risk of dying from all causes” was the message from Tuesday’s Memo. How does that work? Why would stretching decrease mortality? There are no definitive answers, but here are a few possibilities.

It may be that stretching strengthens the blood vessels as well as the connective tissue; that may decrease the potential for blockages or building up plaque in the arteries. Or it may be that the deep breathing that’s associated with most forms of stretching also contributes to the health of the heart and lungs.

One of the other benefits of stretching is a resultant increase in strength, which could help keep the muscles more pliable, and that’s important at any age. I’ve already mentioned that there may be an improvement in arterial function when undertaking stretching, but associated with stretching is a reduction in resting heart rate and an increase in vasodilation. Their possible net impact could lower blood pressure, which would reduce mortality.

I think that one of the most important benefits is going to be related to mobility and balance. We often only think of the flexibility of the muscles of our hips and our knees, but something as simple as raising your hands above your head can benefit stretching those lower joints as well. And all that contributes to your ability to move in space as you get older; maybe you move more if you stretch regularly. By regularly, that means five days a week, the criterion in one of the studies I mentioned.

Finding out the why stretching helps may take a while, but the fact is that there are benefits to what we would consider the easiest forms of exercise. As you move forward through this year, when you have a few minutes in every day, whether it’s waiting for the microwave to finish heating a cup of coffee, washing your hands after using the bathroom, or standing alone on an elevator, taking the time to do purposeful stretching may provide a benefit that you don’t envision. To take it one step further, put together a short routine of three to ten minutes that you do every day; if you have old injuries or joint issues, an appointment with a physical therapist can help you devise a routine you can do safely. And now that spring has sprung and you can get out of the house a little easier, try a class in yoga, tai chi, or qigong. Be sure to look for one that’s within your abilities; Paula and I tried a class a few years ago and were embarrassed that we couldn’t get up and down as easily as the 20-somethings.

The net effect should be that your muscles and your connective tissue will be more pliable. Who knows, you just may end up living a little while longer as well! Sounds like a good investment of time to me.

Reducing Your Risk of Dying the Easy Way

/in /by

Quick! If I were to ask you which form of exercise would decrease your chance of dying, and especially your chance of dying from cardiovascular disease (CVD), what would your answer be? You’d probably pick some form of aerobic exercise such as running, elliptical training, walking, and cycling—any type of exercise that works the heart and the entire body to improve your cardiovascular fitness. That’s on the list for sure, but it’s not the form of exercise that seems to decrease your risk of dying the most. Data from two large observational studies show this form of exercise decreases your risk of dying the most: stretching.

Stretching? Stretching is that toe-touching and heel-to-butt type of stretching we were all taught in high school or some other fitness class. But that’s not all. What also counts as stretching would be activities such as yoga, tai chi, and qigong. They feature slow, elaborate movements that control the body in ways that result in stretching the muscles and other connective tissue. That all counts as stretching.

How much does it reduce mortality? In two large studies, 10% and 12% respectively over the course of several years, the highest reductions in both studies. You get more benefit if you combine it with other forms of exercise such as aerobic training and weight training. But stretching? How or why? I’ll cover that on Saturday.

Dealing with Delayed-Onset Muscle Soreness

/in /by

Muscle soreness generally occurs after a new workout routine, especially weight training. It generally involves eccentric contractions: the simplest way to explain it is the resistance to a movement. During a bicep curl, eccentric contractions would be resisting the lowering of the weight as you return to the starting position. But that’s not exactly what I mean. This is an overall fatigue and soreness that affects more than muscle. Let’s call it delayed-onset body soreness.

What Causes Delayed-Onset Body Soreness?

Movements that are repetitive, that last for hours, that aren’t part of your normal routine—those are the likely causes of delayed-onset soreness. It doesn’t matter how fit you are or how strong you are. While fitness and strength will help, it’s still going to happen occasionally. When you perform movements, even if they’re as simple as standing and answering questions like I did, there are stresses on the ligaments, tendons, and joints as well as the muscles, minute after minute, hour after hour. Micro-tears can occur in multiple types of tissue, and that can cause inflammation and pain.

What you feel the next day is actually the repair process in progress.

Can You Prevent DOBS?

Probably not because it’s caused by something you do infrequently: rake leaves, walk up and down arena steps, shovel snow, or help someone move. But stretching on a regular basis probably helps. Ever stand up, take a deep breath, and reach over your head to stretch just about every muscle in your body? Something as simple as that a few times a day will help keep you limber. Yoga would be great but whatever it is, it has to be consistent to be effective.

The Bottom Line

Infrequent events with repetitive movements are going to happen. I don’t think there’s a need to specifically train for them other than stretching on a regular basis. Taking nutrients such as glucosamine and vitamin C may help the repair process; you can take them in the days leading up to the event as well as after, along with whatever pain meds work best for you. No question that regular aerobic exercise and strength training will help, but most likely won’t prevent soreness. The good news is that this is a problem that should resolve itself quickly.
