Why does a person with muscles that have a higher percentage of slow fibers have greater endurance than a person with muscles that have a lower percentage of slow fibers?
What will be an ideal response?
A person with more slow fibers in a particular muscle will be better able to perform repeated contractions under anaerobic conditions than one with a smaller percentage of this type of fibers, because the latter person's muscles will fatigue less easily. The slow fibers fatigue more slowly because the additional myoglobin they contain stores more oxygen.
