Abstract:
Using impedance-plethysmography, variations in volume of blood-flow of the calves of 34 young adults were observed under different postures: lying, sitting, standing and squatting.Results showed that blood-flow of the calf was of bigger volume in lying position, smaller volume while standing, still smaller while sitting and still smaller while squatting.Data thus obtained are similar to those by other authors using other methods. If the devices used can be further improyed, dynamic measurement of blood-flow volume of human extremities during physical exercises will also be possible.
