Answer:
To provide quick energy to the muscles.
Explanation:
It is advantageous for oxidative muscle fibers to have smaller diameters compared to glycolytic muscle fibers because these fibers depend on aerobic respiration to provide energy to muscle contractions. This smaller diameter enables the oxidative muscle fiber to move very quickly in order to provide quick energy to the muscles. If their diameters are big so they are unable to provide quick energy in the form of ATP to the muscles for their contractions.
