Abstract:

A research program on the influence of high intensity, intermediate duration, low-frequency wholebody vibration on the cardiovascular, renal and respiratory systems is described. During the period 1 June 1974 to 30 june 1975, the major emphasis was on the in vitro study of the transport of I131-albumin between blood and the arterial wall in the presence of oscillatory flow and pressure conditions. A previous series of in vivo experiments has also been extended to include the frequencies of 6 and 14 Hz. These in vivo data indicate an enhancement of albumin uptake in the dog aorta in the presence of vibration and are consistent with the in vitro data and the concept of a shear dependent transport process. An in vitro study of blood-arterial wall cholesterol transport has also been initiated and in vivo measurements of aortic pressure and velocity waveforms in the presence of wholebody vibration are being continued.
