Definition of Anaerobic Capacity. Anaerobic capacity is your body's capacity to run its systems without using oxygen. It contrasts with aerobic capacity, which requires oxygen as fuel. It is therefore important for high-intensity, low-duration activities such as lifting weights or sprinting. Sprint tests are an effective way to measure your anaerobic threshold.
