Patients' inability to perform a preoperative cardiopulmonary exercise test or demonstrate an anaerobic threshold is associated with inferior outcomes after major colorectal surgery. [PDF]

open access: yes, 2013
BACKGROUND: Surgical patients with poor functional capacity, determined by oxygen consumption at anaerobic threshold (AT) during cardiopulmonary exercise testing (CPET), experience longer hospital stays and worse short- and medium-term survival. However,

Stoichiometries of remineralisation and denitrification in global biogeochemical ocean models [PDF]

open access: yes, 2009
Since the seminal paper of Redfield (1934), constant stoichiometric elemental ratios linking biotic carbon and nutrient fluxes are often assumed in marine biogeochemistry, and especially in coupled biogeochemical circulation models, to couple the global ...

Effect of anaerobic bout using wingate cycle ergometer on pressure pain threshold in normal individuals

open access: yesIndian Journal of Pain, 2017
Introduction: Published studies reveal that incremental graded and short term anaerobic exercise lead to an increase in beta-endorphin levels, the extent correlating with the lactate concentration.

The Effects and Differences of Sprint Interval Training, Endurance Training and the Training Types Combined on Physiological Parameters and Exercise Performance [PDF]

open access: yes, 2014
Sprint Interval Training (SIT) is a time efficient way in order to elicit similar changes as Endurance Training (ET) on aerobic capacity, with the purpose of the exercise training to alter physiological systems and exceed resting homeostasis to improve ...

Quantitative Detection of Syntrophic Fatty Acid-degrading Bacterial Communities in Methanogenic Environments [PDF]

open access: yes, 2015
In methanogenic habitats, volatile fatty acids (VFA), such as propionate and butyrate, are major intermediates in organic matter degradation. VFA are further metabolized to H2, acetate and CO2 by syntrophic fatty acid-degrading bacteria (SFAB) in ...

The Notion Of Anaerobic, Lactic And Ventilatory Threshold: Decades Of Contradiction

open access: yesمجلة العلوم و التكنولوجية للنشاطات البدنية و الرياضية
For decades, many studies have addressed the notion of threshold in sports training given its importance in optimizing of the effort. However, the terminology varies depending on the method of measurement and the method of determining this threshold ...

The underpinning of the evaluation of aerobic endurance based on methods established in the late 20th century: A systematic review

open access: yesExercise and Quality of Life
This systematic review aims to analyze the validity (invasive and noninvasive protocols) of aerobic endurance evaluation methods established in the late 20th century and their practical application in creating training series in different sports events ...
