Fast-glycolytic muscle fibers do not require as much oxygen use than slow-oxidative fibers.

Question

Quizplus · Accepted Answer

Fast-glycolytic muscle fibers primarily derive their energy from anaerobic metabolism (without oxygen) via the breakdown of glycogen, whereas slow-oxidative fibers rely more on aerobic metabolism (with oxygen) and oxidative phosphorylation of fats and carbohydrates. Therefore, fast-glycolytic fibers require less oxygen utilization compared to slow-oxidative fibers.
