Exposure to axial unloading induces adaptations in paraspinal muscles, as shown after spaceflights. This study investigated whether daily exposure artificial gravity (AG) mitigated lumbar spine flattening and muscle atrophy associated with 60-day head-down tilt (HDT) bed rest (Earth-based space analog). Twenty-four healthy individuals participated the study: 8 received 30-min continuous AG; 6 × 5-min AG interspersed periods; no (control group). Magnetic resonance imaging (MRI) of lumbopelvic...
This study investigated whether artificial gravity (AG), induced by short-radius centrifugation, mitigated deterioration in standing balance and anticipatory postural adjustments (APAs) of trunk muscles following 60-day head-down tilt bed rest. Twenty-four participants were allocated to one three groups: control group (n = 8); 30-min continuous AG daily intermittent 6 × 5 min 8). Before immediately after rest, was assessed four conditions: eyes open closed on both stable foam surfaces....
This study presents for the first time novel insights into adaptations to hypogravity of spinal curvatures, trunk stiffness, and paraspinal muscle activity. We showed that exposure reduces displacement by an applied perturbation, partially compensated weaker stabilizing contributions muscles concomitant increase in abdominal responses. These findings may have relevance future recommendations planetary surface explorations.
Exposure to spaceflight and head-down tilt (HDT) bed rest leads decreases in the mass of gluteal muscle. Preliminary results have suggested that interventions, such as artificial gravity (AG), can partially mitigate some physiological adaptations induced by HDT rest. However, its effect on muscles is currently unknown. This study investigated effects daily AG during 60-day Twenty-four healthy individuals participated study: eight received 30 min continuous AG; 6 × 5 AG, interspersed with...
Reduced muscle size and accumulation of paraspinal fat content (PFC) have been reported in lumbopelvic muscles after spaceflights head-down tilt (HDT) bed rest. While some information is available regarding reconditioning programs on atrophy recovery, the effects PFC are unknown. Recently, a device (the Functional Re-adaptive Exercise Device-FRED) has developed which aims to specifically recruit muscles. This study aimed investigate standard (SR) program SR supplemented by FRED (SR + FRED)...
Space agencies plan crewed missions to the Moon and Mars. However, microgravity-induced lumbopelvic deconditioning, characterized by an increased fat fraction (FF) due reduced physical activity, poses a significant challenge spine health. This study investigates spatial distribution of FF in muscles identify most affected regions utilizing computer-vision model tile-based approach assess changes. Twenty-four healthy individuals (8F) were recruited, automatic segmentation was applied before...
A discrete control moment gyro (CMG) momentum management scheme (MMS) applicable to spacecraft with principal axes misalignments, such as the proposed NASA dual keel space station, is presented in this paper. The objective of MMS minmize CMG angular storage requirements for maintaining station near local vertical presence environmental disturbances. It utilizes available disturbances, namely gravity gradient torques, minimize storage. executed once per orbit and generates a commanded torque...
