An athlete performing plyometric exercises experiences early fatigue despite good cardiovascular fitness. Which biomechanical factor best explains this issue?

  1. Inadequate joint range of motion limiting elastic energy storage
  2. Excessive eccentric muscle contractions without proper force absorption
  3. Inefficient energy transfer between eccentric and concentric phases
  4. Poor synchronisation of agonist and antagonist muscle groups

\(C\)

Show Worked Solution
  • C is correct: Inefficient energy transfer between eccentric and concentric phases causes muscles to work harder. Fatigue develops faster despite good cardiovascular fitness.

Other options:

  • A is incorrect: While reduced range of motion can limit performance, it would affect power output more than causing early fatigue.
  • B is incorrect: Plyometrics inherently involves eccentric contractions and proper technique includes force absorption. This wouldn’t specifically cause early fatigue if cardiovascular fitness is good.
  • D is incorrect: Poor muscle synchronisation would primarily affect movement quality rather than causing rapid fatigue in someone with good cardiovascular endurance.
