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

Experimental 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 ...

Exercise during 14 days of head down tilt bedrest attenuates motor unit impairments in older humans

Experimental Physiology, EarlyView.
Abstract Head‐down tilt bedrest (HDBR) models the effects of mechanical unloading on neuromuscular function. The efficacy of exercise in preserving motor unit (MU) function in older adults during HDBR remains unclear. This study investigated the effects of 14‐day HDBR on MU properties in older adults and the protective role of exercise.

Dual energy X-ray absorptiometry reference standards for percent body fat and lean body mass in adults

, 2013
Dual energy x-ray absorptiometry (DXA) provides accurate measurements of percent body fat (%BF) and lean body mass (LBM), however no reference standards currently exist using DXA-derived data.

Impact of 14 days of head‐down bed rest and an exercise countermeasure on skeletal muscle atrophy, proteome and circulatory cytokines in older adults

Experimental Physiology, EarlyView.
Abstract Prolonged bed rest and immobilization have deleterious effects on skeletal muscle mass and function, especially in older adults. These can lead to reduced physical capacity and quality of life. Previous experiments in younger individuals show that exercise can mitigate these effects, but evidence remains scarce and inconclusive in older adults.

Effects of 14 days of head‐down bed rest with or without exercise, and subsequent recovery on bone turnover, density and structure in older adults

Experimental Physiology, EarlyView.
Abstract Bed rest accelerates bone loss and may exacerbate skeletal fragility. This study examined the effects of 14 days of head‐down tilt bed rest (HDBR) with or without exercise, and subsequent recovery, on bone turnover, density and structure in older adults. Twenty‐two healthy older adults (55–65 years) completed the HDBR protocol.

Musculoskeletal decay and bone–muscle crosstalk during physical disuse: Mechanisms and integrated countermeasures

Experimental Physiology, EarlyView.
Abstract Older adults experience a markedly increased risk of falls and fractures following hospital discharge, largely due to the rapid musculoskeletal deterioration associated with bed rest. Although age‐related muscle and bone loss typically develops gradually, acute physical inactivity accelerates key biological processes underlying sarcopenia and ...
