Surprising Exercise Science: What’s The Use Of Stretching?

If you’re like me, you  probably feel guilty about not making stretching a part of your regular exercise routine. I attributed my history of low back pain to lack of stretching, although when I began practicing yoga last year I experienced no lasting benefits. Stretching was uncomfortable and I saw very little improvement in my flexibility for all my efforts. I eventually gave up after one well-meaning yogi told me that I may just be “genetically incapable” of making much progress. I turned to strength training and running with complete resolution of my back pain – though with a continued inability to bend over and touch my toes or sit cross legged for prolonged periods. Oh well. No traditional Japanese dining for me!

And so it was with great surprise that I read the conclusions from a recent analysis (by Alex Hutchinson, Ph.D.) of the science of stretching. I recommend that you read it for yourself (along with the links to the primary source literature). But I’m going to summarize his findings here:

Q: Does stretching reduce the risk of injuries during exercise?

A: Not that we can prove.

Q: Does stretching help you avoid soreness after exercise?

A: No.

Q: Does stretching make you stronger or faster?

A: No. In fact, there is some evidence that stretching can have the opposite effect. Why? Muscles have spring-like properties, so that when they are stretched out, they become less able to transmit as much force. Imagine the difference between the power of a thick, metal spring and a thin metal spring. Studies have shown that the more flexible you are, the less efficient you are as a runner.

My take away message is that there’s no need to flagellate yourself into stretching if you don’t like it. It really depends on what you need to do with your body – if you’re a gymnast, then stretching will always be a part of your life. If you’re a runner who hates yoga, so be it. You may never win a toe-touching competition, but then again, you can probably crush the Primal Games competition. Wish me luck as I attempt to do just that in two weeks!

Tips For Dealing With The Chronic Pain Of Osteoarthritis

Severe osteoarthritis of the hands

One of my patients came to see me today with severe right knee pain.  This is not a new problem, and in fact, we have been dealing with flare ups of her osteoarthritis for years.  It mainly affects her knees and hands and today her right knee was swollen and felt like the “bone was rubbing together” with each step. She could hardly walk because of the pain.

Osteoarthritis is also known as degenerative arthritis and it is one of the most common maladies of aging joints, affecting millions of people.  The cartilage in joints wears down and inflammation causes the bones to build up spurs and small micro tears.  It affects women more than men and  the cause is unknown.  There are likely genetic factors as it tends to run in families.  Arthritis can occur in any joint but the most common are the fingers, wrists, hips, neck and spine and knees.  Stiffness (especially in the morning) and pain are the main symptoms that limit mobility.

10 Reasons To Be A Doctor

With all the negative press, the pay cuts, and the uncertainty of healthcare reform, I am approached by people who secretly whisper in my ear, “Would you have your child go into medicine?”

On first blush I am tempted to answer, “Heck no!” given the administrative hassles, the changes in the public’s perception of our profession, the frontload of education, and the long hours involved. But those observations, while real, are superficial at best.

Drilling down with more careful analysis after a challenging weekend on call, I find it worthwhile to stop and ask myself what makes medicine special for those of us crazy enough to subject ourselves to this lifestyle. I decided to put together a list of things that were important to me and would welcome additions from others. Read more »
