Is the anaerobic threshold truly anaerobic?
Chest, 1992This study was done to address the question as to whether there was an exercise metabolic rate below which the O2 supply to the muscles was adequate to meet the O2 requirement and above which the O2 supply was inadequate, ie, an anaerobic threshold (AT). The question was addressed using 2 approaches: (1) The arterial lactate/pyruvate ratio was measured

This chapter describes the changes that occur when anaerobic processes start to supplement aerobic metabolism during a cardiopulmonary exercise test (CPET). Lactic acid is produced, which is buffered by bicarbonate to produce carbon dioxide and water.

Determination of anaerobic threshold: What anaerobic threshold?
Canadian Journal of Statistics, 1991In a recent article in the Consultant's Corner section of this journal, Bennett (1988) considers a problem in the area of kinesiology. Apparently, when humans exercise strenuously, an "anaerobic threshold" is passed; this threshold is defined to be the level of oxygen consumption "just below that at which an abrupt change in metabolism occurs ...

Comparative Biochemistry and Physiology Part A: Physiology, 1993
1. The aim of this study was to find out whether the anaerobic threshold (AT) can be estimated in rats running at increasing speed and if so what is the reproducibility of the measurements. 2. Lactate (LA) concentrations in blood taken from 11 rats were determined during a discontinued, multistage treadmill exercise test repeated four times in each ...

The general interest in the application of exercise testing to evaluate the work capacity or change in the functional ability of individuals has resulted in the development of a variety of non-invasive tests and test parameters such as the anaerobic threshold.

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

Lactate Kinetics and Individual Anaerobic Threshold*
International Journal of Sports Medicine, 1981Exercise with stepwise increasing work loads until exhaustion leads to a curvilinear increase of lactate in blood and typical lactate kinetics in the post-exercise period. Lactate kinetics in blood during exercise and recovery results from diffusion along gradients between muscle and blood and simultaneous elimination.

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
