Which statement about Type I (slow twitch) muscle fibres' physiological adaptations is INCORRECT?

  1. They have high oxidative capacity
  2. They produce rapid, powerful contractions
  3. They have high fatigue resistance
  4. They support endurance activities
Show Answers Only

\(B\)

Show Worked Solution

Type I (slow twitch) muscle fibres:

  • Are characterised by slower contraction speeds and lower power output compared to Type II fibres.
  • Have excellent fatigue resistance and oxidative capacity for endurance activities.
  • Do not produce rapid, powerful contractions – this is a characteristic of Type II (fast twitch) muscle fibres.

\(\Rightarrow B\)
