Chapter 5-Resistance Training Adaptations

Question 0

Motor unit recruitment

Answer 0

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

Question 1

Cellular adaptations to exercise include:

Answer 1

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

Question 2

Rate coding

Answer 2

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

Question 3

Size principal of motor unit recruitment

Answer 3

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

Question 4

Sarcopenia

Answer 4

Progressive decline of muscle mass as one ages
