New Phytologist, EarlyView.Summary Tree stems in Amazonian floodplains emit substantial methane (CH4), yet controls on emission variability remain unclear. Emissions span orders of magnitude between várzea (nutrient‐rich) and igapó (nutrient‐poor) forests and among trees, suggesting controls beyond flooding.

Obesity Reviews, EarlyView.ABSTRACT Excess adiposity is not a recently developed problem but has existed since at least the upper Paleolithic, allowing evolutionary selection pressures to adapt the physiology of the pregnant woman and the feto‐placental unit for maternal and fetal protection.

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.

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 ...

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.
