Team Cross Runs

Stretching Poll Results

The results from the highly scientific Team Cross Runs stretching poll are in!

I’m sure you are sitting on the edge of your seat waiting to find out what most people do so I won’t make you wait any longer.

An overwhelming 33% of runners stretch before and after every workout.

There is a 5 way tie between second place with 17% of runners doing each. The second place categories are:

• Never
• After Hard Workouts only
• Before Every Workout
• I Stretch All the Time

Ok so this poll isn’t really generalizable due to the large size of the poll - only 6 readers responded to my first ever poll. Thanks to those who did! You can see the full results here.

I might try some more polls in the future - keep an eye out for them!

A Controversy of Stretching

I recently reported that I signed up to be included in a USATF sponsored Stretch Study, which is looking at a broad cross section of regular runners to determine if stretching before running (and warming up) helps prevent or causes injuries. A recent New York Times article actually looks into some of the current research around athletes and stretching and comes up with a conclusive answer that isn’t very conclusive!

That doesn’t make any sense does it? Well it seems that the body of current research is very mixed about the importance of stretching and is actually beginning to lean towards the idea that stretching doesn’t actually help an athlete perform better. But when the reporter asked the various researchers if they stretched or not - all of them did!

It has been bantered about in the running community for awhile and more people are beginning to shy away from so called “static stretching” where you hold a stretch for 10 seconds and leaning towards something called “active or dynamic stretching” where you take you muscles through a range of motion and hold any one position for at most 3 seconds.

If your goal is to prevent injury, Dr. Gilchrist said, stretching does not seem to be enough. Warming up, though, can help. If you start out by moving through a range of motions that you’ll use during activity, you are less likely to be injured.

Runners often think that flexibility is important, even to the point of spending hours stretching and doing yoga. One quoted study actually found that…

…distance runners do not benefit from being flexible, he found. The most efficient runners, those who exerted the least effort to maintain a pace, were the stiffest.

A private practice orthopediest went so far to say ““If stretching was a drug, it would be recalled,” Dr. Kenny said.” He claims that stretching actually weakens performance and increases risk of injury.

So what does all of this really mean? Who knows! I think as with much in this life moderation is the key. If you spend lots of time focusing on stretching - it might be better spent somewhere else. You need to find what works best for your body but the extremes probably don’t work for anyone!

Do you stretch? When do you stretch? Take the poll (on the right) and let us know!

USATF - Ongoing Stretch Study

USA Track and Field is in the middle of a very large study on the impact of stretching before you run and running-related injuries.

From their background information:

Many studies have been conducted to understand the impact of stretching or warm-ups on the risk of injury, but with conflicting results. A broad review of “stretching” has not conclusively determined whether a pre-run static stretch protects runners from injury during their routine training.

After reading through the research aka protocol I decided to join the study. The study is focused on three major muscle groups - calves/Achilles, hamstrings, and quadriceps. Volunteers who meet their criteria - any person over 13 who runs 10 miles a week, hasn’t had an injury which prevented running for more than 3 days, is planning on running for the next 3 months, and who is willing to commit to either stretching before running or not stretching before running. The last part may sound kinda logical but there are some who

believe that [pre-run] stretching is important for you to prevent injuries, [if that is you] then you should not volunteer for the Study. If you do not stretch before you run and you believe that stretching before running will increase the possibility of injuring yourself, then you should not volunteer for the Study.

The sign-up process is pretty painless, I think it was 13 simple questions about major health-related issues, your weekly mileage, and a few questions about chronic injuries.

The study process is fairly simple. If you are assigned to stretch, then you stretch. If you are assigned not to stretch, then you don’t stretch the 3 muscle groups. Either way you are allowed to continue with other normal stretching routines before, during or after running. To ensure everyone stretches in a similar manner they have created a how to stretch page to make sure your stretch properly. After the three months you file a report which contains 2 questions - I did or did not get injured during this study and I stretched x% of the time before running. If at any point during the study you get injured which is defined as not being able to run for 3 consecutive days - you file an injury report 3 weeks after the injury occurred.

The study began in April of 2007 and will continue until the maximum size of 10,000 is reached or they produce a statistically significant result.
