Prolonged periods of skeletal muscle inactivity or mechanical unloading (bed rest, hindlimb
unloading, immobilization, spaceflight and reduced step) can result in a significant loss of …

Muscle atrophy and decline in muscle strength appear very rapidly with prolonged disuse or
mechanical unloading after acute hospitalization or experimental bed rest. The current study …

Bed rest studies of the past 20 years are reviewed. Head-down bed rest (HDBR) has proved
its usefulness as a reliable simulation model for the most physiological effects of spaceflight …

The purposes of this study were to determine if the fatigability of the quadriceps femoris
varies by biological sex under conditions of normal muscle blood flow and ischemia, and if …

The bilateral deficit phenomenon, characterized by a reduction in the amount of force from a
single limb during maximal bilateral actions, has been shown in various movement tasks …

Introduction: Head-down bed rest (HDBR) has long been used as an analog to microgravity,
and it also enables studying the changes occurring with aging. Exercise is the most effective …

We investigated the effects of the subacromial impingement syndrome (SIS) on shoulder
sensory‐motor control and maximal shoulder muscle strength. It was hypothesized that both …

Prolonged reductions in muscle activity and mechanical loading (eg, bed rest, cast
immobilization) result in alterations in skeletal muscle form and function. The purpose of this …

To investigate the functional significance of force fluctuations during voluntary contraction
with a select muscle group, we examined the association between force fluctuations during …
