Evaluating the NIRS-derived microvascular O2 extraction 'reserve' in groups varying in sex and training status using leg blood flow occlusions.
Autor: Erin Calaine Inglis, Danilo Iannetta, Juan M Murias
Publikováno v: PLoS ONE, Vol 14, Iss 7, p e0220192 (2019)
It has been demonstrated that the plateau in the near-infrared spectroscopy (NIRS) derived deoxygenated hemoglobin and myoglobin (deoxy[Hb+Mb]) signal (i.e., deoxy[Hb+Mb]PLATEAU) towards the end of a ramp-incremental (RI) test does not represent the

American Ginseng Acutely Regulates Contractile Function of Rat Heart
Autor: Mao eJiang, Juan M Murias, Tom eChrones, Stephen M Sims, Edmund eLui, Earl G Noble
Publikováno v: Frontiers in Pharmacology, Vol 5 (2014)
Chronic ginseng treatments have been purported to improve cardiac performance. However reports of acute administration of ginseng on cardiovascular function remain controversial and potential mechanisms are not clear. In this study, we examined effec

Publikováno v: PLoS ONE, Vol 8, Iss 3, p e59678 (2013)
This study examined the effects of 6 weeks of moderate- (MD) and high-intensity endurance training (HD) and resistance training (RD) on the vasorelaxation responsiveness of the aorta, iliac, and femoral vessels in type 1 diabetic (D) rats. Vasorelaxa

Publikováno v: Physiological Reports, Vol 11, Iss 15, Pp n/a-n/a (2023)
Abstract An index of heart rate variability (HRV), detrended fluctuation analysis (DFA a1) has gathered interest as a surrogate marker of exercise intensity boundaries. The aim of this report was to examine heart rate variability threshold (HRVT) beh

Physiological responses to ramp-incremental cycling tests performed at three simulated altitudes: a randomized crossover trial
Autor: Austin T. Beever, Andrea Y. Zhuang, Saied Jalal Aboodarda, Juan M. Murias, Martin J. MacInnis
Publikováno v: Applied Physiology, Nutrition, and Metabolism. 47:1160-1171
Hypoxia negatively impacts aerobic exercise, but exercise testing in hypoxia has not been studied comprehensively. To determine the effects of simulated altitude on the gas exchange threshold (GET), respiratory compensation point (RCP), and maximal o

A 'Step-Ramp-Step' Protocol to Identify Running Speed and Power Associated with the Maximal Metabolic Steady State
Autor: Cody R, van Rassel, Oluwatimilehin O, Ajayi, Kate M, Sales, Rafael A, Azevedo, Juan M, Murias, Martin J, MacInnis
Publikováno v: Medicine & Science in Sports & Exercise. 55:534-547
A previously established Step-Ramp-Step (SRS) exercise protocol was able to accurately predict the work rate associated with the maximal metabolic steady state (MMSS) in cyclists. The purpose of this study was to determine whether a modified SRS prot

Different ramp-incremental slopes elicit similar V̇O2max and fatigability profiles in females and males despite differences in peak power output
Autor: Rafael de Almeida Azevedo, Pablo R. Fleitas-Paniagua, Mackenzie Trpcic, Danilo Iannetta, Guillaume Y. Millet, Juan M. Murias
Publikováno v: Journal of Applied Physiology.
Purpose: to investigate the effects of different ramp incremental (RI) slopes on fatigability and its recovery in females and males. Methods: Ten females and 11 males performed RI tests with distinct slopes, in separated and randomized sessions, 15 (

Power Output Manipulation from Below to Above the Gas Exchange Threshold Results in Exacerbated Performance Fatigability
Autor: Callum G, Brownstein, Frederic Sabater, Pastor, José, Mira, Juan M, Murias, Guillaume Y, Millet
Publikováno v: Medicine & Science in Sports & Exercise. 54:1947-1960
Performance fatigability is substantially greater when exercising in the severe- versus heavy-intensity domain. However, the relevance of the boundary between moderate- and heavy-intensity exercise, the gas exchange threshold (GET), to performance fa
