[Stretching of the veins of skeletal muscles following changes in the level of hydrostatic venous pressure].

Acute experiments in cats revealed that the integral venous compliance of m. gastrocnemius' could be represented by a graphic curve with ascending front, peak and descending front. These parts of the curve corresponded mainly to those ranges of the venous pressure values: (-10)-0 mm Hg; 0-(+10) mm Hg and (+10)-(+25) mm Hg, resp. The neurogenic component of venous tone in the skeletal muscles has no obvious effect on formation of venous compliance values in response to hydrostatic loads whereas increasing of this tone with noradrenaline or decreasing of it with papaverinum induced, resp., a decrease or an increase in the venous compliance.
