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.

Skeletal muscle properties in long COVID and ME/CFS differ from those induced by bed rest [PDF]

Nature Communications
Patients with long COVID and myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) suffer from post-exertional malaise. The accompanying physical inactivity may contribute to a lower aerobic capacity and may explain skeletal muscle adaptations in ...

Apical hypercontractility mitigates impaired diastolic filling and lower intraventricular haemodynamic forces in human bed rest [PDF]

Experimental Physiology
Prolonged physical inactivity alters the cardiovascular system, including the heart. Long‐term bed rest is known to decrease left ventricular volume and cause diastolic dysfunction; however, the interplay between these changes and their effect on cardiac

Effect of artificial gravity on calcaneal bone marrow adipose tissue and mineral content in female and male participants in 60 days of bed rest [PDF]

Experimental Physiology
Modulation of bone marrow adipose tissue (BMAT) with prolonged inactivity was reported in haemopoietic but not in non‐haemopoietic bones. This prospective randomized controlled trial submitted 16 men and 8 women to 60 days of 6° head‐down‐tilt 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 ...

Effects of head-down bed rest on the executive functions and emotional response. [PDF]

PLoS ONE, 2012
Prolonged bed rest may cause changes in the autonomic nervous system that are related to cognition and emotion. This study adopted an emotional flanker task to evaluate the effect of 45 days -6° head-down bed rest (HDBR) on executive functioning in 16 ...

Mechanical deconditioning of the heart due to long-term bed rest as observed on seismocardiogram morphology

npj Microgravity, 2022
During head-down tilt bed rest (HDT) the cardiovascular system is subject to headward fluid shifts. The fluid shift phenomenon is analogous to weightlessness experienced during spaceflight microgravity.

Early ambulation versus immobilization in the management of patients with distal deep venous thrombosis [PDF]

Ain-Shams Journal of Surgery, 2012
Background: The encouragement of early ambulation with compression rather than bed-rest becomes a matter of controversy. Aim: To evaluate the benefits of compression and walking exercises in comparison with bed rest in the acute stage of distal deep ...
