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.

1991) Multicentre study of the determination of peak oxygen uptake and ventilatory threshold during bicycle exercise in chronic heart failure.
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.
This model suggests that when exercise intensity is above ventilatory threshold, physiological homeostasis is perturbed with an increase in ventilation, muscular contraction, and blood lactate concentration.
Although not competitive at the time of the physiological studies, he was still running three times per week for 30-40 min and cycling for transportation, mostly at intensities below the ventilatory threshold (VT).
max] has been substantially criticized [9, 14, 15] since it seems that the relative parameters alone, without considering the individual ventilatory threshold (IVT), are not sufficient and adequate to individualize exercise intensity [9].
42) A ballet class, for example, was reported to be from low to moderate aerobic intensities, similar to dancers' first ventilatory threshold (VT1) or between first and second ventilatory thresholds (VT2).
Iron supplementation maintains ventilatory threshold and improves energetic efficiency in iron-deficient non-anaemic athletes.
2]max and the second ventilatory threshold (VT2) were established in the test, which was performed on a motorized treadmill (Saturn 250/100R, h/p/Cosmos, Germany).
2011 Automatic detection of maximal oxygen uptake and ventilatory threshold.
University of New Hampshire associate professor of kinesiology Timothy Quinn and his former graduate student Benjamin Coons set out to learn just how good this test, gaining in popularity over the past decade, is, and how it compared to two other laboratory-tested measures of intensity, the lactate threshold and the ventilatory threshold.
Numerous publications over the last 15 years have used a <<two threshold>> model for interpreting lactate and ventilatory threshold tests, as well as demarcating intensity ranges.
A study by Ahmaidi et al (31) investigating the effects of interval training on ventilatory threshold and cardiorespiratory responses in elderly healthy individuals showed significant improvement of both maximal aerobic capacity and submaximal exercise tolerance, with a significant decrease in heart rate after a 3-month program.
