Noninvasive Determination of the Anaerobic Threshold in Swimming
International Journal of Sports Medicine, 1986The relationship between swimming velocity (V) and heart rate (HR) was determined in 60 swimmers. The athletes were asked to increase their work intensity progressively, from low to submaximal velocities; HRs were determined by a telemetric cardiofrequency meter.

Ammonium Ion and the Anaerobic Threshold in Man
Chest, 1991To determine if ammonium ion plays a role in the lactate and ventilatory thresholds of incremental exercise, we investigated the effects on blood lactate and ventilation of NH(4+)-buffering by monosodium glutamate. Six normal volunteers underwent intravenous loading with MSG, 9 g, in a randomized, double-blind, saline placebo controlled crossover study.

The Anaerobic Threshold in Paraplegics
1991The anaerobic threshold (4 mmol/1 lactate) has rarely been described in paraplegics. Investigations with arm crank ergometry in physically unimpaired persons (3, 8) showed a smaller energy consumption corresponding to the smaller muscle mass implemented. Nevertheless, the anaerobic threshold could be demonstrated (8). Most investigations have found the

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 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.

Adaptations to training at the individual anaerobic threshold
European Journal of Applied Physiology and Occupational Physiology, 1992The individual anaerobic threshold (Th(an)) is the highest metabolic rate at which blood lactate concentrations can be maintained at a steady-state during prolonged exercise. The purpose of this study was to test the hypothesis that training at the Th(an) would cause a greater change in indicators of training adaptation than would training "around" the

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 ...

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.

The Reproducibility of the Anaerobic Threshold
1991Incremental treadmill ergometry including lactate and heart rate measurements for assessment of maximum and submaximum performance parameters is the paramount diagnostic procedure for determining performance capacity and for formulating training guidelines (6).

The Anaerobic Threshold Measurement in Exercise Testing
Clinics in Chest Medicine, 1984The exercise intensity (VO2) above which aerobic energy production starts to be supplemented by anaerobic mechanisms is termed the anaerobic threshold (AT). Lactic acid is produced at an increased rate above this work level. Since this acid is almost completely buffered by HCO-3, the rate of CO2 production increases in excess of that being derived from
