<unk>  (also<unk> imal oxygen consumption,<unk> imal oxygen uptake or<unk> imal aerobic capacity) is the<unk> imum rate of oxygen consumption measured during incremental exercise; that is, exercise of increasing intensity. The name is derived from three abbreviations: "V̇" for volume (the dot appears over the V to indicate "per unit of time"), "O2" for oxygen, and "max" for<unk> imum. The measurement of<unk>  in the laboratory provides a quantitative value of endurance fitness for comparison of individual training effects and between people in endurance training.<unk> imal oxygen consumption reflects cardiorespiratory fitness and endurance capacity in exercise performance. Elite athletes, such as competitive distance runners, racing cyclists or Olympic cross-country skiers, can achieve<unk>  values exceeding 90 mL/(kg·min), while some endurance animals, such as Alaskan huskies, have<unk>  values exceeding 200 mL/(kg·min).
