QOTD: Lets talk about compression. Do you use compression gear? If so, do you run with it, for recovery, or both? Do you find that it helps any?
I have a pair of Zensah calf sleeves. I used to use them after every long training run. They really make a difference for post-recovery running and made me feel stronger and quicker afterwards. However, I recently read that wearing them too often could be a dampener to adaptations that occur after long training runs. Part of the process of cumulative fatigue and long training runs is to put stress on your body so that it learns to adapt. So now I've switched to using the calf sleeves only after races or during my Dopey days after each race. They really can make a dramatic difference post-recovery.
As far as the science goes, for post-recovery workouts there is good science to say that it works. Similar to people who wear them because of diabetes. Helping blood flow.
But the during running science isn't there yet. The science has shown that the current markers for physiological performance show no changes between people with or without compression gear on. As many people have said it could be a mental placebo effect. But the scientist in me says that there has to be something there. Too many people use it successfully. It's really hard to do a blind clinical trial with calf sleeves because it would be quite obvious to the subject whether they were or weren't wearing them. So it's near impossible to remove the placebo effect unless you use naive subjects who know nothing about compression gear. With that being said, I believe that it's probably one of two things at work: 1) placebo effect or 2) more recently I've thought it just could be a matter of something that science just hasn't found the benefit that already exists. It's quite possible that the studies done to date have missed the mark on what the beneficial change is when wearing them. It doesn't mean they're not beneficial, just we don't know why yet.
But in the end does it really matter? As long as you think they work for you and they work for you, then go for it.
An interesting parallel study was one with runners and running clothes. Can't remember all of the details well but essentially the study was on people and their perception of running clothes. They were given a few options to run in and were told to evaluate them based on performance. In all cases they were the exact same item except they had a different branding item on it. Thus, the singlet was exactly the same but they put a Nike swoosh, or Saucony logo, or Target logo, or a Marshall's logo on it. And you know what? People ran better in the Nike items. Why? Because people subconsciously thought the Nike item was a better product because it was Nike. And because they "felt better" and "felt faster" in the Nike item. They felt superior running in it because it was name brand even though the item was exactly the same.
So to tie it back to the compression gear, it doesn't matter the reason why it works because if it works keep doing it. If you run faster in compression gear, then by all means run with it on. I'm all about trying to find every legal competitive advantage I can find to make me a better runner.
