Muscle

Question

Which of the following type of muscle fibres will be the first one to undergo fatigue?

Difficult

A

Slow oxidative fibres
B

Fast oxidative - glycolytic fibres
C

Fast glycolytic fibres
D

Aerobic fibres

Solution

Skeletal muscle fibres are three types;
a) Slow oxidative (SO) fibres: contract relatively slowly and use aerobic respiration (oxygen and glucose) to produce ATP;
b) Fast oxidative (FO) fibres: have relatively fast contractions and primarily use aerobic respiration to generate ATP.
c) Fast glycolytic (FG) fibres: have relatively fast contractions and primarily use anaerobic glycolysis and undergo fatigue quickly.
