If given the exact same amount of atp, which of the three fiber types would be able to contract for the longest amount of time?

a. both fast glycolytic and fast oxidative fibers
b. slow oxidative fibers
c. fast glycolytic fibers
d. fast oxidative fibers

The correct answer is B.

Explanation:

Skeletal muscle fibers are classified based on "how does it regenerates ATP" and "how fast does it contract compared to others". Compared to the other types of fibers slow oxidative fibers are known to produce low power contraction and these contractions persists over long time periods compared to the fast oxidative and fast glycoltic fiber types.
