Ans. A. B has done more work than A
- A: Preload
- B: Afterload.
- In preloaded condition, the relaxed state.
- In afterloaded condition, the load acts on the muscle only when its actively contraction and is supported during the relaxed state.
- External work done: Load x displacement
- In this diagram displacement is higher in B so more work is done there.
