Explanation:
Detailed explanation-1: -Exercises typically thought of as anaerobic consist of fast twitch muscles eg sprinting, high-intensity interval training (HIIT), power-lifting. Sustained anaerobic exercise, causes a sustained increase in lactate and metabolic acidosis.
Detailed explanation-2: -Lactic acid is formed and accumulated in the muscle under conditions of high energy demand, rapid fluctuations of the energy requirement and insufficient supply of O2. During intense exercise sustained to fatigue muscle pH decreases to about 6.4-6.6.
