Retinal venular vessel diameters are smaller during ten days of bed rest [PDF]

Scientific Reports, 2023
Older individuals experience cardiovascular dysfunction during extended bedridden hospital or care home stays. Bed rest is also used as a model to simulate accelerated vascular deconditioning occurring during spaceflight.

The effect of 60 days of 6° head-down-tilt bed rest on circulating adropin, irisin, retinol binding protein-4 (RBP4) and individual metabolic responses in young, healthy males [PDF]

Frontiers in Physiology
BackgroundAlterations in the circulating concentrations and target-tissue action of organokines underpin the development of insulin resistance in microgravity and gravity deprivation.

Initial Glutathione Depletion During Short-Term Bed Rest: Pinpointing Synthesis and Degradation Checkpoints in the γ-Glutamyl Cycle [PDF]

Antioxidants
Hypokinesia triggers oxidative stress and accelerates the turnover of the glutathione system via the γ-glutamyl cycle. Our study aimed to identify the regulatory checkpoints controlling intracellular glutathione levels.

Changes in real-world walking speed following 60-day bed-rest [PDF]

npj Microgravity
The aim of this work was to explore whether real-world walking speed (RWS) would change as a consequence of 60-day bed-rest. The main hypothesis was that daily RWS would decrease after the bed-rest, with a subsequent recovery during the first days of re ...

Capillary rarefaction during bed rest is proportionally less than fibre atrophy and loss of oxidative capacity

Journal of Cachexia, Sarcopenia and Muscle, 2022
Background Muscle disuse from bed rest or spaceflight results in losses in muscle mass, strength and oxidative capacity. Capillary rarefaction may contribute to muscle atrophy and the reduction in oxidative capacity during bed rest.

The effect of short‐term exercise prehabilitation on skeletal muscle protein synthesis and atrophy during bed rest in older men

Journal of Cachexia, Sarcopenia and Muscle, 2021
Background Poor recovery from periods of disuse accelerates age‐related muscle loss, predisposing individuals to the development of secondary adverse health outcomes.

The Aging Muscle in Experimental Bed Rest: A Systematic Review and Meta-Analysis

Frontiers in Nutrition, 2021
Background: Maintaining skeletal muscle mass and function in aging is crucial for preserving the quality of life and health. An experimental bed rest (BR) protocol is a suitable model to explore muscle decline on aging during inactivity.Objective: The ...
