Explanation:

Predominantly glycolytic type II fibers rely more on anaerobic glycolysis for energy production. Anaerobic glycolysis produces lactic acid as a by - product, which leads to fatigue more quickly compared to oxidative metabolism in other fiber types. Oxidative type I fibers and predominantly oxidative type II fibers have better endurance due to their reliance on oxidative phosphorylation.

Answer:

Predominantly glycolytic type II fibers
