| Popis: | Contains fulltext : 70794thijssen.pdf (Publisher’s version ) (Closed access) This study was performed to assess the effect of resistive vibration exercise during bed rest deconditioning on venous vascular dimension and function, as measured with ultrasound in the popliteal vein. Sixteen men were assigned to bed rest (BR-Ctrl) or bed rest with resistive vibration exercise (BR-RVE). Before and at 25 and 52 days of bed rest, popliteal vein diameter was measured at increasing cuff pressures. Venous capacitance and compliance were calculated from the pressure-volume curve. After 52 days of bed rest, BR-Ctrl showed no change in baseline popliteal vein diameter or compliance, while venous capacitance decreased. Resistive vibration exercise had no effect on the response in venous diameter, capacitance or compliance to 52 days of bed rest. The decline in venous capacitance due to long-term bed rest is not effectively counteracted by resistive vibration exercise, indicating that an alternative factor during bed rest deconditioning is responsible for venous changes. |
