J Appl Physiol (1985)
. 2025 Jan;
138(2):389-396.
PMID: 39751173
Measurement of blood flow during exercise is crucial for understanding physiological responses and performance outcomes. However, traditional methods are often invasive, costly, or require substantial training, limiting widespread research in...

Am J Physiol Heart Circ Physiol
. 2024 Nov;
327(6):H1467-H1473.
PMID: 39485296
The accuracy of femoral artery blood flow measurements via Doppler ultrasound hinges on assumptions of laminar flow upstream of the femoral bifurcation. Existing scanning guidelines recommend a minimum proximity to...

Ultrasound Med Biol
. 2024 Sep;
50(12):1849-1853.
PMID: 39278803
Objective: The arterial wall not only moves in the radial direction to expand circumferentially but also moves in the axial (longitudinal) direction in a predictable bidirectional pattern during a normal...

PMID: 38935328
Background: Traditional electrocardiography (ECG)-derived heart rate variability (HRV) and photoplethysmography (PPG)-derived "HRV" (termed PRV) have been reported interchangeably. Any potential dissociation between HRV and PRV could be due to the...

. 2024 Jun;
49(10):1436-1440.
PMID: 38885533
We recently explored the cardiopulmonary interactions during partial unloading of the respiratory muscles during exercise. Expanding upon this work, we present a noteworthy case study whereby we eliminated the influence...

J Appl Physiol (1985)
. 2024 May;
137(1):32-41.
PMID: 38813612
Blood volume shifts during postural adjustment lead to irregular distension of the internal jugular vein (IJV). In microgravity, distension may contribute to flow stasis and thromboembolism, though the regional implications...

. 2024 Jan;
5(12):870-880.
PMID: 38204855
Background: Insufficient cardiac output in individuals with heart failure (HF) limits daily functioning and reduces quality of life. Although lower cerebral perfusion, secondary to limitations in cardiac output, has been...

. 2024 Jan;
56(5):953-962.
PMID: 38181209
Purpose: Sedentary behavior may contribute to increased central wave reflection due to associated peripheral vasoconstriction, yet its impact on central hemodynamics and the mitigating effects of interventional strategies have not...
