White muscle fibers, also called fast-twitch glycolytic fibers, are specialized for rapid, powerful contractions over short periods. They have less myoglobin and few mitochondria, which makes them appear pale and limits their capacity for aerobic respiration. They primarily rely on anaerobic glycolysis for energy. However, the amount of sarcoplasmic reticulum is actually high in white fibers, as it allows rapid release and reuptake of calcium ions to facilitate quick contractions. Therefore, stating that the sarcoplasmic reticulum is low is incorrect.
