Step 1
This requires a high amount of force production, which is primarily generated by the fast-twitch muscle fibers, also known as Type II fibers. Within the Type II fibers, there are two subtypes: Type IIa and Type IIx. Type IIa fibers have a higher endurance Show more…

If you were to research a group of sprinters' muscle fiber composition, which fiber type(s) would you expect to make up the lowest percentage of the gastrocnemius (calf)? Group of answer choices: - Fast oxidative glycolytic fibers - Not enough information to determine the lowest percentage. - Slow oxidative fibers - Fast glycolytic fibers
