Question

Quizplus · Accepted Answer

The relative number of slow oxidative fibers does not decrease with aging. Instead, there is a general decline in muscle mass and function, including a decrease in maximal strength, an increase in non-contractile tissue (fibrous connective tissue and adipose tissue), and a slowing of muscle reflexes. Slow oxidative fibers are more resistant to fatigue and are used for endurance activities; their proportion relative to other fiber types does not necessarily decrease with age.
