The Anaerobic Threshold in Paraplegics

1991
The 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

Anaerobic threshold

Abstract Key Points: • A long-standing concept in CPET is the presence of a ‘threshold’ during progressive incremental exercise, termed the anaerobic threshold (AT). • Although controversial, the AT is thought to represent a point during CPET where anaerobic processes increasingly supplement aerobic

"Anaerobic threshold": problems of determination and validation

Journal of Applied Physiology, 1983
Despite 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 in runners and cyclists.

The Journal of sports medicine and physical fitness, 1989
Two 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.

Noninvasive Determination of the Anaerobic Threshold in Swimming

International Journal of Sports Medicine, 1986
The 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, 1991
To 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.

Lactate Kinetics and Individual Anaerobic Threshold*

International Journal of Sports Medicine, 1981
Exercise 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.

The Reproducibility of the Anaerobic Threshold

1991
Incremental 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).

Adaptations to training at the individual anaerobic threshold

European Journal of Applied Physiology and Occupational Physiology, 1992
The 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

Canadian Journal of Statistics, 1988
AbstractThis 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.
