Solution

To answer this question, we need to understand the different types of motor units and their characteristics in terms of fatigue resistance and force generation.

  1. S (Slow) Motor Units: These motor units are highly resistant to fatigue and can maintain force generation for extended periods. However, they generate less force compared to other types of motor units.

  2. FF (Fast Fatigable) Motor Units: These motor units generate a high amount of force but fatigue very quickly. After a few minutes of repeated stimulation, they can only generate a fraction of their maximum force.

  3. FR (Fast Resistant) Motor Units: These motor units generate a moderate amount of force and are more resistant to fatigue than FF motor units. They can maintain force generation for a longer period compared to FF motor units.

Given this information, let's fill in the blanks:

  • After a few minutes of repeated stimulation, FF motor units can generate only a fraction of their maximum force.
  • S motor units maintain maximum force generation after an hour of repeated stimulation.

So, the correct answer is:

FF; S
