The Muscular System#

[DRAFT OUTLINE — Claude]

Planned coverage:

• Muscle structure - fibre, myofibril, sarcomere
• The sliding filament mechanism
• Fibre types I, IIa, IIx - and why “conversion” is mostly a myth
• The three energy systems, and why they all run at once
• Mechanical tension as the primary hypertrophy signal
• Sarcomeres in series vs in parallel - length vs girth
• Metabolic byproducts, buffering, and local fatigue

Feeds: Power, Strength, Hypertrophy, Muscular Endurance, Anaerobic Capacity.
