"Anaerobic endurance"

Question

Quizplus · Accepted Answer

Anaerobic endurance is characterized by the ability to sustain high-intensity exercise for a short period of time, typically relying on the breakdown of carbohydrates in the absence of oxygen. This type of endurance is mainly supported by the contractions of fast muscle fibers, which have a high capacity for anaerobic metabolism. Therefore, option B is the best choice. Option A is incorrect because anaerobic endurance is not used during long, slow athletic activities which require aerobic metabolism. Option C is incorrect because the availability of substrates for breakdown is important for energy production, but it does not define anaerobic endurance. Option D is incorrect because mitochondrial activities are mainly involved in aerobic metabolism, not anaerobic. Option E is incorrect because anaerobic endurance can lead to muscle hypertrophy in some cases.
