The impact of healthy motion seating on lower‐limb blood flow and blood pressure response to simulated long‐haul air travel

Experimental Physiology, EarlyView.
Abstract Prolonged sitting inherent to long‐haul air travel can acutely decrease lower‐limb blood flow and increase brachial blood pressure. Healthy motion seating (HMS), which passively alters sitting interface pressure and posture, is a promising technology which may attenuate the deleterious effects of long‐haul air travel. The aim of this study was

Time-Frequency Analysis of Cardiovascular and Cardiorespiratory Interactions During Orthostatic Stress by Extended Partial Directed Coherence

Entropy, 2019
In this study, the linear method of extended partial directed coherence (ePDC) was applied to establish the temporal dynamic behavior of cardiovascular and cardiorespiratory interactions during orthostatic stress at a 70° head-up tilt (HUT) test on ...

Limited musculoskeletal benefits of artificial gravity combined with cycling during bed rest: Results from the BRACE study

Experimental Physiology, EarlyView.
Abstract Prolonged exposure to microgravity, simulated via 6° head‐down tilt bed rest (HDT), induces musculoskeletal deconditioning and negatively impacts body composition. This study evaluated whether a combination of aerobic exercise with artificial gravity (AG) offers superior protection in comparison to exercise alone.

Clinical profile and cardiovascular autonomic function tests in patients with postural orthostatic tachycardia syndrome

CHRISMED Journal of Health and Research, 2019
Background: Postural orthostatic tachycardia syndrome (POTS) is an autonomic disorder characterized by the clinical symptoms of orthostatic intolerance such as light-headedness, fatigue, sweating, tremor, anxiety, palpitation, exercise intolerance, and ...

Heat Therapy: Targeting Health, Disease, and Disability

Comprehensive Physiology, Volume 16, Issue 1, February 2026.
The predominance of evidence suggests heat therapy has an impact on all aspects of health and performance, but the drivers of that improvement, the extent to which they are improved, and the specific populations in which improvements manifest are far from completely understood.

Effect of aerobic capacity on Lower Body Negative Pressure (LBNP) tolerance in females [PDF]

This investigation determined whether a relationship exists in females between: (1) aerobic capacity and Lower Body Negative Pressure (LBNP); and (2) aerobic capacity and change in LBNP tolerance induced by bed rest. Nine females, age 27-47 (34.6 plus or

Epidural Spinal Cord Stimulation of Lumbosacral Networks Modulates Arterial Blood Pressure in Individuals With Spinal Cord Injury-Induced Cardiovascular Deficits

Frontiers in Physiology, 2018
Disruption of motor and autonomic pathways induced by spinal cord injury (SCI) often leads to persistent low arterial blood pressure and orthostatic intolerance.

Effects of 12 weeks of upper‐body rowing exercise on autonomic cardiovascular control and vascular structure in spinal cord‐injured humans

Experimental Physiology, Volume 111, Issue 2, Page 375-389, 1 February 2026.
Abstract Spinal cord injury (SCI) is characterized by autonomic cardiovascular dysfunction that may contribute to the three‐ to fourfold greater risk of heart disease and stroke compared to non‐injured individuals. While exercise training elicits beneficial changes in autonomic function and vascular structure in healthy individuals, it is unclear if ...

Development of limb volume measuring system [PDF]

The mechanisms underlying the reductions in orthostatic tolerance associated with weightlessness are not well established. Contradictory results from measurements of leg volume changes suggest that altered venomotor tone and reduced blood flow may not be

Investigation of in vivo measurement of cerebral cytochrome-c-oxidase redox changes using near-infrared spectroscopy in patients with orthostatic hypotension [PDF]

, 2007
We have previously used a continuous four wavelength near infrared spectrometer to measure changes in the cerebral concentrations of oxy- (Δ[HbO2] and deoxy- haemoglobin (Δ[HHb]) during head-up tilt in patients with primary autonomic failure.
