The anaerobic threshold: 50+ years of controversy

open access: yesJournal of Physiology, 2020
The anaerobic threshold (AT) remains a widely recognized, and contentious, concept in exercise physiology and medicine. As conceived by Karlman Wasserman, the AT coalesced the increase of blood lactate concentration ([La−]), during a progressive exercise

Anaerobic Threshold Biophysical Characterisation of the Four Swimming Techniques

open access: yesInternational Journal of Sports Medicine, 2020
The anaerobic threshold (AnT) seems to be not only a physiologic boundary but also a transition after which swimmers technique changes, modifying their biomechanical behaviour.

Oxygen uptake efficiency slope in healthy normal weight young males: an applicable framework for calculation and interpretation [PDF]

open access: yesPeerJ, 2022
Background The oxygen uptake efficiency slope (OUES) is considered a reliable indicator of cardiorespiratory fitness in young and clinical populations who cannot achieve maximal effort during a graded exercise test.

The comparison of endothelial function of moderate intensity interval exercise with continuous exercise in healthy men

open access: yesCurrent Research in Physiology, 2022
Background/aim: Exercise enhances endothelium-dependent vasodilation; however, it is unclear whether intermittent exercise has a different effect on vascular endothelial function compared to continuous exercise.

Alternative method for determining anaerobic threshold in rowers

open access: yesRevista Brasileira de Cineantropometria e Desempenho Humano, 2008
http://dx.doi.org/10.5007/1980-0037.2008v10n4p367 In rowing, the standard breathing that athletes are trained to use makes it difficult, or even impossible, to detect ventilatory limits, due to the coupling of the breath with the technical movement. For

Thermodynamic modelling of synthetic communities predicts minimum free energy requirements for sulfate reduction and methanogenesis [PDF]

open access: yes, 2020
Microbial communities are complex dynamical systems harbouring many species interacting together to implement higher-level functions. Among these higher-level functions, conversion of organic matter into simpler building blocks by microbial communities ...
