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

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, muscle volume and hypoxia
European Journal of Applied Physiology and Occupational Physiology, 1989Ventilatory threshold, apparent mechanical efficiency, oxygen debt repayment, heart rate and perceptions of exertion at the ventilatory threshold have been examined in 8 men and 8 women during the performance of four types of exercise (2-leg, 1-leg, arm plus shoulder, and arm ergometry) under normoxic and hypoxic (12% oxygen) conditions.

Anaerobic threshold measurements of elite oarsmen
Medicine & Science in Sports & Exercise, 1982Anaerobic threshold (AT) and Vo2max were determined by automated analysis for 25 members of the 1980 U.S. Olympic Rowing Team during a progressive rowing ergometer exercise to exhaustion. Heart rates and power outputs were also measured to gauge severity of the exercise and to compare with metabolic data. Power increments of 27 W each min were achieved

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 ...
