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.

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.
