Abstract:

Of the various stresses imposed upon subjects performing critical tasks, time dependent accelerations vibration can produce some of the greatest discomfort and decrements in performance. The effects of this stress on the cardiovascular system are being investigated in the laboratory. Instrumented animals are used to evaluate the cardiovascular changes produced by whole body, sinusoidal vibration. Experiments are designed to evaluate the role of five major mechanisms which current evidence indicates are the main factors producing these changes. Cardiovascular, hematological, and mechanical variables are used to evaluate the overall stress level.
