Final answer:

A single muscle twitch does not generate maximum muscle force due to factors such as insufficient time for calcium release and power stroke completion.

One twitch does not cause the maximum force a muscle is capable of because:

  • The short stimulus does not give the action potential time to get to the T tubules.
  • There is not enough time for the power stroke to be completed.
