Question

Quizplus · Accepted Answer

Aerobic exercise does not typically lead to an increased number of fibers in a motor unit. Instead, it primarily leads to increased mitochondrial density, blood supply, myoglobin supply, and the activity of lipoprotein lipase. Motor units are composed of a single motor neuron and the muscle fibers it innervates, and their number is largely determined genetically and does not change significantly with exercise.
