E) Muscle fibers become less efficient.

When we exercise, our muscles require energy in the form of glycogen to function. With consistent exercise, the body adapts by increasing the amount of glycogen stored in muscle fibers, allowing them to work harder and longer without fatigue. This is an example of a muscular adaptation.

Options A, B, C, and E are not examples of muscular adaptations resulting from exercise. Muscle fibers become larger in diameter with exercise, not smaller (option A). Muscles become more elastic with regular exercise, not less (option B), and they actually fatigue less rapidly due to increased endurance (option C). Finally, muscle fibers become more efficient with exercise, not less (option E).
