SLOW-TWITCH (Type I, red) muscle fibres are characterised by:
AMany glycogen stores + anaerobic (sprinting)
BMany mitochondria + aerobic (endurance work)
CFew mitochondria + rapid fatigue easily
DFound mainly in the human eye (not in limb)
Answer & Solution
Correct answer: B. Many mitochondria + aerobic (endurance work)
Slow-twitch (Type I, RED) fibres: many mitochondria, much MYOGLOBIN (red colour), AEROBIC, ENDURANCE specialist (marathon, posture). Fast-twitch (Type II, white): glycogen-rich, anaerobic, fast + powerful but fatigues quickly (sprint, jumps).
