I. Muscle growth
is dependent on 2 things:
- Utilization of amino acids by muscle cell for cellular
growth (bigger myofibrils).
- Entry of amino acids (final breakdown product of protein
For this to occur the amino acids must be in the serum
(blood) and they must have the mechanism to get into the cell.
Working out lowers blood sugar. The body shuts or slows
down the insulin production. The body produces glucagon to raise blood sugar.
Insulin is the primary driver of amino acids into the cell.
II. Workout too hard and:
- burn all your energy reserves
- shut down insulin production
- increase glucagon production
- start working out on your "neuro transmitters"
(norepinephrine) you shake "over tonus"
- blood sugar falls
- amino acids dont get into cell
- muscle growth cant occur
- muscle growth can only occur after the work out when over
tonus subsides (eat)
- Keep Amino Acids high in blood.
- Keep insulin going (production).
- Dont burn-off all energy reserves during workout, so
you dont shut off all the insulin.
