Key Points

To determine the effects of acute supine rest and resulting fluid shifts on computed tomography measurements of mid-thigh tissue cross-sectional area.
Mid-thigh axial scans were acquired in 13 older women using computed tomography (CT) after 5, 10, and 15 minutes of resting in the supine position.
Scans were evaluated for changes across time in the cross-sectional area (CSA) of subcutaneous fat, low-density muscle, and normal-density muscle.
Normal-density muscle cross-sectional area decreased significantly from baseline by 2.3 ± 0.8 cm² (± SE), representing a 1.6% decrease at 15 minutes (P < 0.05).
No significant changes were observed in the cross-sectional area of low-density muscle or subcutaneous fat across any of the evaluated time intervals.
