Question

Is athletic performance related to muscle fiber type? Distance runner Paula Radcliffe has won dozens of long-distance races and has held the world record in the marathon for over a decade. Scientists, trainers, and athletes alike have wondered about the extent to which muscle structure and function contribute to success in athletes like Radcliffe. What makes elite distance runners so good? Are their muscles somehow different from those of less successful athletes and non-athletes? Part A Compare and contrast the structure and function of the three types of skeletal muscle fibers Drag the appropriate items to their respective bins

Explanation / Answer

Answer:

Oxidative fibers are red because they have a lot of myoglobin and these fibers contract slowly and do not fatigue rapidly.

Glycolytic fibers are white due to low myoglobin concentration and they contract and fatigue rapidly.

Intermediate fibers have physiological properties between red and white fibers and they are pink.
