Chapter 43.1, Problem 3SB

Summary Introduction

To review:

The differences among slow aerobic, fast aerobic, and fast anaerobic muscle fibers with respect to contraction intensity, fatigue resistance, oxidative phosphorylation capacity, number of mitochondria, and myoglobin content.

Introduction:

Muscle fibers based on the rate of contraction and resistance to fatigue can be categorized into three types such as a slow aerobic muscle fibers, fast aerobic muscle fibers, and fast anaerobic muscle fibers. Each of these muscle fibers perform contractile function differently in the body.
