metabolic and related thresholds

intensities of exercise (expressed as power output or as percentages of aerobic capacity, O2 max) at which specific metabolic and related changes are considered to take place. A plethora of thresholds has been proposed historically. These included many giving the same label to different criteria, or different labels to the same criterion; a number also embodied assumptions about bodily processes, at best unproven and sometimes now known to be false. The table lists six which appear unambiguous, the first five exactly as first described and the sixth slightly modified; however the two that are not related to observable phenomena (anaerobic and aerobic thresholds) are not recommended for further use. The [Lac]b (blood lactate concentration) values cited are representative approximations for a healthy but untrained young adult; they are used in some laboratories as working indices, but should not be taken as definitions of the term concerned. Other usages in the literature include: (1) OBLA as equivalent to LT or AT - confusions possible only if the reference to continuous rise is omitted from the OBLA definition; (2) the 4 mmol.L- criterion being designated as any one of 'anaerobic', 'aerobic' or 'aerobic/anaerobic' thresholds.
