Summary of underlying eccentric training effects that may benefit hypertrophy, strength, and power output.

Hypertrophy	Strength	Power Output
↑ Anabolic signaling ↑ Satellite cell activation ↑ Motor unit recruitment ↑ Activation of motor cortex ↑ Force production capacityPossible ↑ fast twitch motor unit preferential recruitment	↑ Motor unit recruitment ↑ Activation of motor cortex ↑ Force production ↑ Motor unit discharge rate ↑ MTU stiffness ↓ Regulation of inhibitory reflexesPossible ↑ fast twitch motor unit preferential recruitmentPossible ↑ type IIx fiber composition (phenotype shift)	↑ Motor unit recruitment ↑ Activation of motor cortex ↑ Force production capacity ↑ Motor unit discharge rate ↑ MTU stiffness ↓ Regulation of inhibitory reflexes ↑ Muscle fascicle lengthPossible ↑ fast twitch motor unit preferential recruitmentPossible ↑ type IIx fiber composition (phenotype shift)Possible ↑ excitation–contraction coupling rates ↑ Muscle fiber shortening velocity
