Type 2 muscle fibers are aerobic?

Yes, type 2 muscle fibers, also known as oxidative or slow-twitch fibers, are aerobic in nature. These muscle fibers are specifically designed for endurance activities and oxidative metabolism. They contain an abundance of mitochondria, which are the energy powerhouses of the cells and help in the efficient production of energy through aerobic respiration. Type 2 muscle fibers utilize oxygen to generate ATP, which is the primary energy currency of the body. They have a rich capillary network that ensures an adequate supply of oxygen and nutrients to support prolonged muscle contractions during low-intensity, long-duration activities such as marathons or long-distance cycling.
