Evaluation of noninvasive cardiac output methods during exercise [PDF]

open access: yes
Noninvasive techniques to estimate cardiac output (Qc) will be used during future space flight. This retrospective literature survey compared the Qc techniques of carbon dioxide rebreathing (CO2-R), CO2 single breath (CO2-S), Doppler (DOP), impedance (IM)

Accuracy of Consumer Grade Bioelectrical Impedance Analysis Devices Compared to Air Displacement Plethysmography [PDF]

open access: yes, 2011
The purpose of this study was to examine the accuracy of percent body fat estimates from seven different bioelectrical impedance analysis (BIA) models and a seven-site skin fold formula (SKF) compared with air displacement plethysmography (ADP) in ...

FNDC4 and FNDC5 Attenuate SARS‐CoV‐2 S1‐Induced Inflammatory Responses in Human Adipose Tissue

open access: yesEuropean Journal of Clinical Investigation, Volume 56, Issue 5, May 2026.
In obesity, reduced FNDC4 and FNDC5 amplify SARS‐CoV‐2 S1–driven inflammation in visceral adipose tissue. These adipo‐myokines limit adipocyte–macrophage inflammatory signalling, suggesting a protective role against viral‐induced adipose tissue dysfunction.

Influence of low‐dose dopamine on exercise in fibrosing interstitial lung disease

open access: yesExperimental Physiology, Volume 111, Issue 5, Page 2682-2695, 1 May 2026.
ABSTRACT Fibrotic interstitial lung disease (FILD) is associated with dyspnoea and exercise intolerance. In other cardiorespiratory conditions, heightened carotid body (CB) chemoreflex sensitivity is associated with reduced exercise capacity. We tested the hypothesis that CB chemoreflex inhibition would improve exercise endurance time (EET) and reduce ...

Magnitude and variability of blood pressure and renal vascular conductance responses to postural changes, exercise, and cold in black adults: A pilot study

open access: yesPhysiological Reports, Volume 14, Issue 9, May 2026.
Abstract We developed a noninvasive approach to measure vascular responses to sympathetic stimuli. We hypothesized that standing, handgrip exercise, or cold exposure would raise blood pressure (BP) and lower renal vascular conductance (RVC). BP was recorded continuously and renal arterial velocity was measured using renal Doppler ultrasound.

Cerebral blood velocity responses during and after sprint interval exercise in healthy young adults

open access: yesPhysiological Reports, Volume 14, Issue 9, May 2026.
Abstract This study investigated the middle (MCAv) and posterior (PCAv) cerebral artery blood velocity and end‐tidal carbon dioxide (PETCO2) responses during sprint interval exercise (SIE). We also examined the relationships between MCAv, PCAv and blood pressure during the 60 min post SIE.

Evaluation of a Circumference-based Prediction Equation to Assess Body Composition Changes in Men [PDF]

open access: yes, 2013
International Journal of Exercise Science 6(3) : 188-198, 2013. This study evaluated the validity of the current U.S. Department of Defense (DOD) circumference-based prediction equation for males to detect body composition changes in comparison to air ...
