Indicate which of the characteristics in question apply to each of the muscle fiber types by using the following answer code (more than one answer may apply):
-Is found predominantly in muscles adapted for short- duration, high-intensity activities.

Question

Quizplus · Accepted Answer

Fast-glycolytic fibers are adapted for short-duration, high-intensity activities. They rely mainly on anaerobic metabolism and have a high capacity for glycolysis, which can generate ATP quickly but only for a short time.

Answer: B
 Fast-oxidative fibers are also adapted for high-intensity activities, but they have a higher oxidative capacity and can generate ATP both aerobically and anaerobically. They are often found in muscles that need to contract quickly and powerfully, such as the leg muscles used for sprinting or jumping.

Answer: A 
 Slow-oxidative fibers are adapted for endurance activities and are not as suitable for high-intensity activities. They rely mainly on aerobic metabolism and have a high capacity for oxidative phosphorylation, which can generate ATP over a long period of time but at a slower rate. They are often found in muscles used for sustained activities such as jogging or cycling.
