无氧运动

noun

anaerobic exercise; high-intensity physical activity in which oxygen consumption exceeds the body's ability to supply oxygen, primarily utilizing glycogen and phosphocreatine rather than oxygen to produce energy

Typically involves short bursts of maximum effort such as sprinting (100m, 200m, 400m), heavy weightlifting, or high-intensity interval training (HIIT). Contrasts with aerobic exercise which uses oxygen to burn fat and can be sustained for longer periods. Characterized by the production of lactate and rapid fatigue.
