ventilatory threshold

ven·til·a·to·ry thresh·old

(ven'til-ă-tōr-ē thresh'ōld)
Point during exercise training at which pulmonary ventilation becomes disproportionately high with respect to oxygen consumption; believed to reflect onset of anaerobiosis and lactate accumulation.

Moreover, it was also verified that the predominant activity above the ventilatory threshold contributed to a progressive increase of HRfrom round to round, thus also contributing to a great perception of fatigue in the last rounds.
However, the oxygen ([O.sub.2]) pulse kinetics was abnormal, showing a decrease from the first ventilatory threshold ([VT.sub.1]) with no electrical modification on the electrocardiogram (from 14 to 13mL x [beat.sup.-1] between [VT.sub.1] and [VO.sub.2peak]).
