Hello,
I have a question regarding muscle physiology. Check out a little bit of what I did today:
BB Military Press
1 x 20 with 100 lbs (~50% of my 1 rep max....stop laughing!!!!!)
then I took a rest for 1 minute (timed)
1 x 20 with 105 lbs (failure...delts burning like hell)
then I took a rest for 1 minute 30 seconds (timed)
1 x12 with 110 lbs (failure....but it wasn't muscle burning type failure...on the 12th rep I was still feeling alright but when I tried to get 13th rep, I just couldn't move my arms...they were just paralyzed and I had to stop the set).
Can someone explain what exactly happened here in terms of muscle biology? Did I use up all my deltoid glycogen? Did Type 1 muscle fibers tire out and type 2 were taking over? Did my CNS get overloaded? Did I burn up all my shoulder ATP??
By the way, in case you're wondering, I'm experimenting with low 1 RM maxes (30-50%) and doing sets to failure because I read in an article that you still get muscle hypertrophy whether you use 30% or 80% as long as you do more reps (~30 reps) with the lower 1-rm max.
Thanks!
