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, 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

Determination of anaerobic threshold
Canadian Journal of Statistics, 1988AbstractThis report describes the estimation of the parameters for a model of ventilation (y) by human subjects as a two‐segment linear function of oxygen uptake (x). Experimental data were supplied by R.L. Hughson of the Department of Kinesiology. The analysis of one of nine available sets of data is described in detail.

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

Anaerobic Threshold of Anuran Amphibians
Physiological Zoology, 1984The metabolic responses to graded levels of exercise were determined for three species of anuran amphibians (Bufo americanus, Hyla crucifer, and Rana sylvatica). Both oxygen consumption ($\dot{V}_{O_{2}}$) and lactate production were measured at low, moderate, and high levels of mechanically stimfilated activity.

Determination of Anaerobic Threshold by Ventilatory Frequency*
International Journal of Sports Medicine, 1989Detection of anaerobic threshold (AT) requires either invasive techniques or expensive gas analyzers and somewhat complicated procedures. The purpose of this study was to determine if ventilatory frequency (f) could be used to detect AT. Thirteen (seven females) healthy, non-smoking, physically active adults (21-44 years) volunteered to perform ...

"Anaerobic threshold": problems of determination and validation
Journal of Applied Physiology, 1983Despite the popularity of the concept of “anaerobic threshold” (AT), the noninvasive detection criteria remain subjective, and invasive validations of AT have been based on lactate data of arterial, mixed venous, venous, and capillary blood samples without any concern for the possible lactate differences from these sources.

ANAEROBIC THRESHOLD AND KERNEL ESTIMATORS
Italian Journal of Applied Statistics, 2017The transition threshold from aerobic to anaerobic metabolism of athletes practising endurance sports is identified with the deflection point in the graph of cardiac frequency versus velocity. A parametric statistical background was provided (Calderoni et al., 1990) by assuming a transition from linear to parabolic regression.

Anaerobic Threshold in Total Artificial Heart Animals
ASAIO Journal, 1994The anaerobic threshold represents an objective measure of functional capacity and is useful in assessment of pulmonary and cardiovascular dysfunction. This study determined the anaerobic threshold in total artificial heart animals and evaluated the performance of the total artificial heart system.

Anaerobic threshold in runners and cyclists.
The Journal of sports medicine and physical fitness, 1989Two different noninvasive procedures have been used to determine the anaerobic threshold (AT) in 15 long distance runners and in 6 cyclists. The AT values obtained by ventilatory methods (on treadmill for runners and on cycloergometer for cyclists) and the AT values obtained by a field test were significantly correlated.
