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.

Gait analysis for functional evaluation in a surgical hindlimb suspension model of muscle atrophy

The Journal of Physiology, EarlyView.
Abstract figure legend Gait analysis reveals neuromuscular dysfunction following hindlimb suspension and partial recovery after reloading. Schematic overview of the experimental design and principal findings. Mice underwent 14 days of hindlimb suspension (HLS), resulting in muscle atrophy marked by reduced fiber size, satellite cell loss, and decreased

A computational model for retinal haemodynamics under gravitational and postural variations

The Journal of Physiology, EarlyView.
Abstract figure legend The haemodynamic impact of gravitational and postural changes on the retina, and its relevance to spaceflight associated neuro‐ocular syndrome (SANS), remains incompletely characterized. This study assesses retinal haemodynamics from upright to head‐down tilt using a lumped‐parameter model that dynamically couples intraocular ...
