Stretching Cold Muscles?

Dr. Tim Noakes in his book last copyrighted in 1991, Lore of Running,stated that “recent” evidence shows that stretching done when the muscles are warm is no better than when the muscles are warm; hence, he advocated stretching before any warm-up. Years and years ago runners would stretch before running. Then the general knowledge was to warm up first to warm the muscles. Now Dr. Noakes is going back to where we were before. Does anyone have any info or cites on this subject?

Also, recent studies show that stretching does not help in preventing injuries. Again, does anyone have any info and/or cites?

I haven’t got a cite for it, but my tae kwon do instructor (an MD/PhD student studying orthopedics, so he tends to follow this stuff) told me a couple of weeks ago about a study he’d read recently in one of the major medical journals that showed that most injuries are a result of lack of balance rather than lack of flexibility. The old idea was that you got hurt if something got pulled/stretched beyond its usual range of motion, so you could prevent injuries by increasing that range through stretching. This study, however, showed that most injuries actually happen within the person’s normal range of motion, but when it gets pulled at a bad angle, ie not the usual one that it wants to go in. (Imagine knees getting twisted or pushed sideways rather than the usual hinging forwards and backwards.) This happens when people lose their balance and try to compensate with muscles/ligaments that aren’t used to being used that way, and thus get injured. I think the authors of the study advocated balance training for injury prevention in athletes.

Whatever turns your crank! or whatever is in style at the moment.

Exercise entheusiasts at the health club go to the steam room and do all kinds of stretching first, and others just go straight to the exercise rooms or the racquet ball courts.

I tried both ways when I began running. I found that I was able to run longer and had less soreness when I warmed up by walking for five minutes, stretched, and then ran. I found that when I simply stretched “cold”, I would get out of breath faster, got sore while running, and wanted to quit halfway. So from personal experience, it helped me exercise better. I don’t know about preventing injuries, I’ve luckily never gotten injured. But I’m not a hardcore runner or weight lifter, or what have you…

Not sure if you are familiar with Pavel Tsatsouline, but he pretty much says the same thing: stretching isn’t necessary to warm up the muscles. Pavel himself seems to suggest that stretching can make you reliant on stretching, and thus set yourself up for injuries that wouldn’t normally occur if you didn’t stretch.

Here is a cite or two: You are being redirected.... In fact the author of that cite claims that stretching can hinder your performance:

According to a USNEWS article (take it at face value, since they don’t cite sources), Stretching might even cause more problems than it prevents.

Now, these are the only cites I have offhand, but at one time I had much more. I don’t think this conclusively proves anything, and there are an equal number of cites that can be thrown around on both sides. There is a growing number of credible scientific journals that are publishing studies showing that stretching is not the magic preventer we are brainwashed into thinking, but it is gaining momentum rather slowly if at all. As anectdotal evidence, I have been lifting and running for years now, and have never once stretched before a workout. I have had no injuries, but as a caveat, it must be said that I do not train in Triathalons or train heavily into martial arts. I do stretch, but not before a workout, I stretch for what little martial arts I do participate in. YMMV obviously.

Personally I doubt you are going to find evidence that will convince a person either way. I think if the average athlete or gym rat wants to stretch, more power to them. There are always risks, and stretching still seems to pose little to no real danger. Unless you are training all the time for the Olympics or something. And then you are paying for the best trainer anyhow, and certainly will not listen to a few cites on a message board.

Sorry, here is the fixed USNEWS link.

Thanks, Epimethus. It appears then that one should not stretch before a run or race or whatever, contra to the advise for lo these many years. I’ll limit my stretching for after the run from now on.

Just to confuse the matter further, traditional static stretching (30 second holds) has been shown to decrease strength in the stretched muscles, while PNF stretching may increase strength and may also be a lot more useful for static flexibility. So the type of stretching you do probably has an effect on the outcome you get.

Here is a contrary opinion, but altho it is by PubMed, it is not annotated.
