Lesson 1 • Cardiovascular Limitation Patterns

Identifies low VO2peak, flat oxygen pulse, and early AT as hallmarks of cardiovascular exercise limitation. Distinguishes heart failure, ischemia, and chronotropic incompetence by CPET signature.

Lesson 2 • Peripheral and Muscular Limitation

Detects low work efficiency, early lactic acidosis, and normal cardiovascular reserve as peripheral limitation signs. Covers mitochondrial myopathy, peripheral artery disease, and deconditioning.
