Cellular adaptations to exercise include:

Changes in anaerobic enzyme quantities
Changes in stored energy substrates (glycogen, phosphagen)
Increased myofibrillar protein content

1

Motor unit recruitment

Process in which tasks that require more force involve activation of more motor units

2

Rate coding

Control of motor unit firing rate. The faster the firing rate, the more force is produced

3

Size principal of motor unit recruitment

Smaller motor units (slow twitch) are recruited at lower force levels and larger motor units (fast twitch) are recruited at higher force levels.

4

Sarcopenia

Progressive decline of muscle mass as one ages
