I don't have evidence, but I just don't believe that it's so bad. I think the risks to your back of squats and DLs with holding your breath are greater that the dangers of the Valsalva effect.
So is this like the squatting deep argument? One side says Blah, the other says Anti-Blah. (thinking about it, ithink i hold my breath on the DL too.)
I’m not going to pretend to understand a lot of what I just read here: http://en.wikipedia.org/wiki/Valsalva_maneuver
But basically it means your heart could “explode” from too much pressure, and there is less blood circulation while the pressure from holding your breath is present? I’m not worried about that personally, but is that the side that says not to do its concern?
Like KPj said, it feels right and feels natural. I just did it, and wasn’t even thinking about it. At the top of my squat, I took a big breath, chest up, ass out, and started. I hadn’t even realized I didn’t breathe out until I stood back up.
It is similar to about 4 to 6 weeks ago when I settled under the bar to squat and the bar just kind of rolled down from the top of my traps to about mid shoulder. It felt “more right” lower on my shoulders, and as long as I keep my hands close it just fits right in there. It wasn’t a conscious movement; it just rolled down there on its own…
I tried holding my breath on bench too, and the major thing I noticed was I could drive my legs much better when I wasn’t breathing so much. I don’t know if it is because I could think about it more, because I wasn’t doing 6,000 things at once, just 5,900, or what, but I felt my bench in my Hamstrings… So weird to me.
I have to read the entire article still, I only scanned it when Peter gave it to me last night, but thanks for the input. Now I’m super curious of what the general consensus is.
Maybe I should start a poll… Ha Ha those go over so well…
