Clinical significance: When characterizing occupational demands, researchers often use mean or peak values or 1 standard deviation above the mean. However, mean oxygen consumption is unlikely to adequately characterize non-steady-state tasks. Therefore, using time spent in different oxygen-consumption zones may represent a superior method for characterizing physical activities of intermittent intensity.
