Question

Which muscle fiber type is best suited for endurance activities, such as long-distance jogging? Which muscle fiber type is best suited for endurance activities, such as long-distance jogging?
a. slow glycolytic fibers
b. slow oxidative fibers
c. fast oxidative fibers
d. fast glycolytic fibers

Answer 1

Answer: Slow oxidative fibers

Explanation:

Slow oxidative fibers are best suited for the activities that requires endurance such as long distance jogging.

Slow oxidative fibers have the structural elements in it which maximizes the  ability to generate the ATP through aerobic metabolisms.

These fibers contain more mitochondria as compared to the glycolytic fibers as a part of aerobic metabolism.

The activities such as jogging, cycling requires a constant amount of energy through out the activity and hence, slow oxidative fibers are essential for these activities.
