Adaptations to Strength Training:

Neural Adaptations ­

Increased recruitment of additional fast twitch muscle fibres
Increased recruitment of motor units
Improves coordination and simultaneous stimulation of motor units
Reduction in proprioreceptor / antagonist muscle inhibition allowing antagonist to
stretch further and agonist to contract with more force

Physiological Adaptations ­…
