Why is cold water immersion particularly effective for athletes experiencing delayed onset muscle soreness?

  1. It reduces nerve conduction speed, lowering pain perception
  2. It maintains high heart rate to flush lactic acid
  3. It dilates blood vessels to increase inflammation
  4. It increases adrenaline release for faster tissue repair

\(A\)

Show Worked Solution
  • A is correct: Cold water immersion reduces nerve conduction speed, which lowers the perception of pain. It also minimises inflammation, making it effective for relieving muscle soreness.

Other options:

  • B is incorrect: A high heart rate is not maintained. Cold water immersion (CWI) lowers heart rate and promotes recovery.
  • C is incorrect: CWI causes vasoconstriction, not vasodilation. It therefore reduces rather than increases inflammation.
  • D is incorrect: Adrenaline release is linked to arousal and stress, not effective muscle recovery.
