Evidence that the metabolic acidosis threshold is the anaerobic threshold
Journal of Applied Physiology, 1990We evaluated maximal O2 uptake (VO2max), the metabolic acidosis threshold determined by the V-slope analysis [plot of CO2 output (VCO2) as a function of oxygen uptake (VO2)], the ratio of increase in VO2 to work rate increment (delta VO2/delta WR), the upper slope (S2) of the V-slope analysis, and the VO2 for work below and above the metabolic ...

Anaerobic Threshold in Children
Pediatric Exercise Science, 1989The ventilatory anaerobic threshold (VAT) occurs when there is an isolated increase in the slope for ventilator equivalent for oxygen consumption (VE/VO2) with no change in the slope for ventilatoiy equivalent for carbon dioxide production (VE/VCO2) when both are plotted against time. The concept of anaerobic threshold remains controversial.

Anaerobic threshold and lactate turnpoint
European Journal of Applied Physiology and Occupational Physiology, 1983Venous lactate concentration and ventilatory responses to progressively increased work rates were studied in 16 men who performed an incremental exercise test to exhaustion on an electrically braked cycle ergometer. In this test the characteristic curvilinear increase in venous lactate concentrations was observed. In addition to the anaerobic threshold

The double anaerobic threshold in heart failure
International Journal of Cardiology, 2022Cardiopulmonary exercise test (CPET) has an important role in assessing heart failure (HF) patients. Among CPET parameters, a pivotal role is attributed to the anaerobic threshold (AT), normally determined by V-slope, ventilatory equivalent and end-tidal methods.

Possible Mechanisms of the Anaerobic Threshold
Sports Medicine, 1988The anaerobic threshold consists of a lactate threshold and a ventilatory threshold. In some conditions there may actually be 2 ventilatory thresholds. Much of the work detailing the lactate threshold is strongly based on blood lactate concentration. Since, in most cases, blood lactate concentration does not reflect production in active skeletal muscle,

Detection of the Anaerobic Threshold by Surface Electromyography
2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006This work aims at presenting a method for automatic detection of the anaerobic thresholds by surface electromyography (RMS-slope) and compare with respective values identified by the analysis of ventilatory gas exchange. Thirteen healthy adults were submitted to a single maximal oxygen uptake test, being monitored the ventilatory parameters V(O2), V ...

Medicine & Science in Sports & Exercise, 1985
The concentration of lactate in the blood is the result of (1) those processes which produce lactate and contribute to its appearance in the blood and (2) those processes which catabolize lactate after its removal from the blood. Consequently, the concentration of lactate in the blood provides minimal information about the rate of lactate production in

Platelet aggregability in relation to the anaerobic threshold
Thrombosis Research, 1994Platelet aggregability might be increased during physical exercise. This, in turn, has been explained by the elevation of plasma catecholamines and by the state of lactic acidosis, which occur at high exercise intensities. The purpose of this investigation was to study the relationship between changes in platelet aggregability and exercise intensity ...

Anaerobic threshold, individual anaerobic threshold, and maximal lactate steady state in rowing
Medicine & Science in Sports & Exercise, 1995Anaerobic threshold, also termed 4.0 mmol.l-1 threshold (AT4), and individual anaerobic threshold (IAT), presumably indicate the workload corresponding to maximal lactate steady state (MLSS) during an incremental workload test. MLSS is the highest blood lactate concentration (BLC) resulting in a steady state during constant workload. The purpose of the

The respiration pattern as an indicator of the anaerobic threshold
2015 37th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2015The anaerobic threshold (AT) is a good index of personal endurance but needs a laboratory setting to be determined. It is important to develop easy AT field measurements techniques in order to rapidly adapt training programs. In the present study, it is postulated that the variability of the respiratory parameters decreases with exercise intensity ...
