Abstract:

A research program on the influence of high intensity, intermediate duration, low frequency wholebody vibration on the cardiovascular, renal, and respiratory systems has been initiated. During the period June 1, 1973 to May 31, 1974, the major emphasis was on the study of the transport of albumin between blood and the arterial wall. Using 131I-albumin, a series of in vivo experiments have been carried out at a frequency of 10 Hz and a half-amplitude of 0.635 cm as well as at control conditions. These data indicate an enhancement of albumin uptake in the dog aorta in the presence of vibration and are consistent with the concept of a shear dependent transport process. Measurements of aortic pressure and velocity waveforms and, regional blood flow distribution, have also been carried out. Initial results are presented although these experiments are still in progress. Author
