Muscle Hypertrophy vs. Hyperplasia | How Muscle Grows

Muscle Hypertrophy vs. Hyperplasia:

Myofibrils/ satellite cells are activated by a hormonal cascade

Testosterone causes GH release and helps convert IGF-1 to MGF

IGF-1 turns into mechano growth factor MGF and increases Protein synthesis

Higher Volume Training is typically optimal for testosterone response

Steps: Stimulus, signal, gene expression, protein synthesis

Tendon growth:

Hormone response can increase collage deposition
Extracellular matrix expands and reforms
Increased tissue tolerance
You can do more plyometrics
You can run longer, faster, jump higher without getting hurt
