Finger blood flow decrease in leg exercise

Finger blood flow (FBF) was measured with mercury-in-silastic strain gauge venous occlusion plethysmography before, during and after 2-min leg exercise on a Monark bicycle ergometer at exercise intensities of 0, 60, 90 and 120 watts. The FBF rapidly decreased in all subjects immediately after the onset of exercise, and was as maintained at low levels during exercise. The amount of decrease in FBF observed during exercise seemed to be independent of exercise intensity.
