The direction of venous return was monitored continuously by the Doppler method at 4 MHz, in order to study the effects of posture and certain kinesitherapeutic maneuvers on venous return in the foot of young, healthy and trained adults (kinesitherapy monitors, yoga assistants). It was noted that: the acceleration of venous return in the foot was expiratory in the recumbent position and inspiratory in the standing position; dorsiflexion (leg on foot or toes on heel) caused a more pronounced spurt phenomenon than plantar flexion; massage repeated at high frequency is less beneficial for venous return than slower massage, which allows better adaptation of venous compliance.
