The Slow Oxidative Fibers

The Slow Oxidative Fibers. Also known as red fibers and oxidative fibers type I. Based on metabolic pathways utilized muscle fibers are categorized as slow oxidative SO fast oxidative FO and fast glycolytic FG.

Slow oxidative fibers have structural elements that maximize their ability to generate ATP through aerobic metabolism. Create your own flashcards or choose from millions created by other students. Type I muscle fibers are typically the smallest fiber type this is assessed by measuring their diameter not length.

They have the highest resistance to fatigue and they are the most efficient fiber type.

Power-producing muscles have a higher density of fast glycolytic fibers than of slow oxidative fibers. Slow-twitch Type I Muscle Fibers. They possess a high number of mitochondria and their major source of energy is through aerobic metabolism. Slow-twitch muscle fibers type I and fast-twitch muscle fibers type II.
