Spiracular fluttering increases oxygen uptake.

PLoS ONE, 2020
Many insects show discontinuous respiration with three phases, open, closed, and fluttering, in which the spiracles open and close rapidly. The relative durations of the three phases and the rate of fluttering during the flutter phase vary for individual

Comparative Contributions of Oxygen Uptake Efficiency and Maximal Oxygen Uptake to Fat Oxidation Metrics in Healthy Male Adults [PDF]

Sports Medicine - Open
Background Maximal fat oxidation (MFO) and its intensity (FATmax) are important for metabolic health, but current models explain only partially their variability.

Análisis de la relación entre el Yo-Yo Test y el consumo máximo de oxígeno en jóvenes jugadores de fútbol. [Analysis of the relationship between Yo-Yo Test and maximum oxygen uptake in young football players]. [PDF]

Revista Internacional de Ciencias del Deporte, 2014
This work aimed to examine the validity of the Yo-Yo Endurance Test Level 1 to estimate the maximum oxygen uptake in football players. Participants were 15 male football players, ranging in age from 17 to 19 years old (M = 17,9; DT = 0,67), who developed

The reliability of back-extrapolation in estimating V˙O2peak in different swimming performances at the severe-intensity domain

Frontiers in Physiology, 2022
The amount of anerobic energy released during exercise might modify the initial phase of oxygen recovery (fast-O2debt) post-exercise. Therefore, the present study aimed to analyze the reliability of peak oxygen uptake (V˙O2peak) estimate by back ...

Optimal and freely chosen paddling rate during moderate kayak ergometry

Biology of Sport, 2021
Moderate paddling, as in long distance kayaking, constitutes an endurance activity, which shares energetic aspects with activities such as long distance running and road cycling.

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

PeerJ, 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.

Maximal oxygen consumption and oxygen uptake efficiency in adolescent males

Journal of Exercise Science & Fitness, 2021
Background/objective: Measures of oxygen uptake efficiency (OUE) have been used to evaluate cardiorespiratory fitness (CRF) in adolescents unable to perform maximal exercise. The oxygen uptake efficiency slope (OUES) and oxygen uptake efficiency plateau (

Increase in peak oxygen uptake and Andersen test performance in children from age six to ten: The Health Oriented Pedagogical Project (HOPP)

Frontiers in Physiology, 2022
The increased prevalence of non-communicable disease risk factors among children because of lack of physical activity is concerning. The Health Oriented Pedagogical Project was set up to combine learning activities and physical activity, thus reducing ...

Decadal variability of oxygen uptake, export, and storage in the Labrador Sea from observations and CMIP6 models

Frontiers in Marine Science, 2023
The uptake of dissolved oxygen from the atmosphere via air-sea gas exchange and its physical transport away from the region of uptake are crucial for supplying oxygen to the deep ocean.

Uptake rate of cationic mitochondrial inhibitor MKT-077 determines cellular oxygen consumption change in carcinoma cells. [PDF]

PLoS ONE, 2012
OBJECTIVE:Since tumor radiation response is oxygen-dependent, radiosensitivity can be enhanced by increasing tumor oxygenation. Theoretically, inhibiting cellular oxygen consumption is the most efficient way to increase oxygen levels.
