The purpose of this investigation was to study the effect of time of day on the relationship between lactate (LT) and ventilatory thresholds (VT) of pulmonary oxygen uptake (VO 2). Thresholds - Lactate Testing. This is a discussion that is on the Secrets of Lactate CD-ROM - we have put it here for all who are interested. Before you proceed on there will be a few places where the reader can place their mouse such as here and additional information will appear. So watch for these places. The anaerobic threshold is the point in the exercise continuum at which there is a rapid decrease in cellular pH. 9 It can be directly determined by measuring muscle pH or indirectly determined by analyzing blood lactate. 10 The least invasive method of estimating anaerobic threshold is to assess systemic metabolic and ventilatory parameters. Physiological variables, such as maximum work rate or maximal oxygen uptake (V̇O2max), together with other submaximal metabolic inflection points (e.g. the lactate threshold [LT], the onset of blood lactate accumulation and the pulmonary ventilation threshold [VT]), are regularly quantified by sports scientists during an incremental exercise test to by:
The purpose of this study was to compare the peak aerobic capacities and ventilatory anaerobic thresholds (VAT) of individuals with a traumatic brain injury (TBI) to age- and gender-matched en participants that previously suffered a mild to moderate TBI and 19 apparently healthy controls volunteered as subjects.

Physiological testing of elite athletes requires the correct identification and assessment of sports-specific underlying factors. It is now recognised that performance in long-distance events is determined by maximal oxygen uptake .VO2max), energy cost of exercise and the maximal fractional utilisation 2max in any realised performance or as a corollary a Cited by: Lactate values during a m may reach >15 mmol/L whereas lactate values during a half marathon may be closer to mmol/L. And since lactate threshold has been found to be closely correlated with pH threshold (Morris and Shafer, ), it’s safe to assume that intramuscular/plasma pH falls lower during m running than it does. The physical fitness indicators used under submaximal exercise tests, like heart rate, lactate and ventilatory thresholds (Achten and Jeukendrup, ; Billat et al. ), as well as predictive submaximal exercise tests (Noonan and Dean, ) have been sufficiently studied and validated; however, the RER, which indirectly shows the muscle Cited by: tive, this modality of physical reconditioning leads to improved functional exercise capacity and reduced breathlessness. Early implementation is desirable to obtain more meaningful responses (e.g., when FEV1 falls below 50% of the predicted value in patients with chronic obstructive disease). Preparation for effective EXT requires optimization of respiratory system mechanics .
