Changes of reactive hyperaemia after clinical bed rest for seven days

As an indication of peripheral circulatory function reactive hyperaemia was studied in the forearm and calf muscle in 14 healthy young men before and after clinical bed rest for one week. Blood flow was measured after different arterial occlusion times with venous occlusion plethysmography. After bed rest peak flow values in the calf after arterial occlusion for 3 or 5 minutes decreased moderately (by about 20-23%) and significantly. Peak flow in the forearm decreased as well although not significantly.
