Good thoughts, good post! Strength recovery, and just recovery is really important IMO too. I read this after my post above and looks like your post is saying similar to my thoughts too, that's what I've seen too with myself and my own recovery. If I train 3x per week per muscle, it ends up being 3 small 'bouts' anyway, so I'm sure the overall long term stimulus comes out about the same as lesser often bigger bouts. ( I know in the past when I've compared it it has anyway). Plus that other thought I've posted a couple times on here (and even once to Kreiger on FB) and cannot get anyone to 'bite' and think about it...... (I'll post it one more time here...) We know an SD makes muscle tissue more sensitive to stimulation. There is even a study showing how mTOR gets blunted with regular training. That study showed that about 12 days off, reset mTOR and re-sensitized it either fully or almost fully. OK, since that seems to be so, that means, when those subjects took 12 days off, there was some kind of ramp of sensitivity slowly increasing with each day off. So THAT means, if you train on Monday for example, take Tuesday off, a little sensitivity was restored, if you wait another day, a little more was restored, another day off, even more, etc. That might be why and how 1x per week can be so close to 3x per week, your getting a 'mini SD' between each workout, mTOR would be much more sensitive and maybe respond a lot more to a training bout. I think this might be pretty important in the frequency/stimulation area.
