Quizplus · Accepted Answer

Fast glycolytic skeletal muscle fibers are designed for producing a high amount of force. This is achieved through a larger cross-sectional area, which allows for more myofibrils and sarcomeres to be packed into the muscle fiber, resulting in a greater amount of force production.
