Very interesting study, basically bicarbonate is a alkaline buffering agent, ingesting it prior to exercise apparantly delayed the onset of acidosis in muscle. The delay in acidosis would ofcourse mean the PCr is regenerated faster and therefore allow you to do more volume in the exercise.
I would like to see a resistence exercise study like this and measurements of mTOR and P70S6k taken!
This would move us one step closer to determining if it is volume or acidosis in the muscle that determines hypetrophy.
I've been putting baking soda in my sports drinks for years now, and it definitely seems to help things when engaged in protracted activity like going out for a mountain bike ride.
