anaerobic exercise

anaerobic exercise,

any short-duration exercise that is powered primarily by metabolic pathways that do not use oxygen. Such pathways produce lactic acid, resulting in metabolic acidosis. Examples of anaerobic exercise include sprinting and weight lifting. Compare aerobic exercise. See also active exercise, passive exercise.

anaerobic exercise,

n physical activity, which instigates a metabolism that does not depend on oxygen. Examples include isotonics, in which the muscles contract against an object of resistance with movement (e.g., weight lifting); isometrics, in which muscles contract against resistance but without movement; and calisthenics (e.g., sit-ups and knee-bends), which increase flexibility and improve joint mobility.

anaerobic bacteria

see anaerobe.

anaerobic effluent treatment

is usually conducted in deep ponds where air does not penetrate. A fully contained system is also available.

anaerobic exercise

exercise at high work intensity during which the needs of muscle metabolism for oxygen exceeds the capacity of the circulation to supply it and an oxygen debt is incurred.

anaerobic infection

one caused by aerobic organisms.
