A multi‐omics investigation of sarcopenia and frailty: Integrating genomic, epigenomic and telomere length data

open access: yesExperimental Physiology, EarlyView.
Abstract Sarcopenia and frailty are complex geriatric syndromes influenced by a combination of genetic and environmental factors. Recent studies suggest that specific genetic variants, DNA methylation patterns and shortened telomeres are associated with age‐related diseases and might contribute to the development of both sarcopenia and frailty.

The effects of bed rest on cardiometabolic health: A systematic review and meta‐analysis

open access: yesExperimental Physiology, EarlyView.
Abstract Horizontal bed rest (HBR) and head‐down tilt (HDT) are models of physical inactivity. In this systematic review and meta‐analysis, we aimed to quantify changes in cardiometabolic outcomes during HBR and HDT in healthy adults. Following the PRISMA guidelines, we searched PubMed, Scopus, Web of Science and Cochrane Library until 1 October 2025 ...

Dual-energy x-ray absorptiometry (DEXA)

open access: yes, 2017
Dual-energy x-ray absorptiometry (DXA), was first developed to assess bone mass, however it also provides information on fat mass (FM) and fat-free mass (FFM) (Mazess et al., 1990) As such, the DXA is commonly used to assess body composition in both research and clinical practice Participants of this study will be scanned using the Lunar Prodigy (GE ...

Sex differences in cerebral blood flow and cardiac function in response to exercise in the heat

open access: yesExperimental Physiology, EarlyView.
Abstract We investigated the effect of exercising in hot conditions on cerebral blood flow and systolic left ventricular (LV) function in males and females, to explore sex differences. The experimental condition consisted of walking on a treadmill at 5 km/h and 2% incline, inside a heat chamber at 40°C (50% relative humidity), for 90 min.

Monte Carlo modelling of X-ray absorptiometry and its application to body composition studies

open access: yes, 1996
This thesis applies Monte Carlo techniques to the study of X-ray absorptiometric methods of bone mineral measurement. These studies seek to obtain information that can be used in efforts to improve the accuracy of the bone mineral\ud measurements.

Cerebral oxygenation and skeletal muscle responses to time trial, maximal oxygen uptake and time to exhaustion exercise

open access: yesExperimental Physiology, EarlyView.
Abstract This study investigated cerebral and neuromuscular responses to three exercise models: time trial (TT), maximal oxygen uptake (V̇O2max${{\dot{V}}_{{{{\mathrm{O}}}_2}{\mathrm{max}}}}$) and time to exhaustion (TTE). Fourteen participants completed the tests in the following order: V̇O2max${{\dot{V}}_{{{{\mathrm{O}}}_2}{\mathrm{max}}}}$, TT and ...

Quantifying microvascular responses to local heating using optical coherence tomography: Comparison between skin sites and sex differences

open access: yesExperimental Physiology, EarlyView.
Summary of the study design, metholodgy, results and conclusions. Abstract Due to a lack of technical capacity to directly visualise and quantify microvessels in the skin, little is known regarding regional and/or sex differences. We compared diameter, velocity, flow and density at four regional sites using a novel optical coherence tomography (OCT ...
