URINARY EXCRETION OF VANILMANDELIC ACID AFTER PLUS GX IMPACT IN HUMANS

Abstract

Seven volunteer subjects were exposed once each to 25 plus Gx impact and sham impact on the Daisy Decelerator. Urinary excretion of vanilmandelic acid (VMA) was measured during two timed periods prior to and after impact or sham impact. The results indicate that the average urinary excretion of VMA increases with exposure to both impact or sham impact. The greatest average increase was observed after true impact. It is suggested that subject anxiety attendant to both experimental conditions causes an increased liberation of catecholamines. True impact may further stimulate this adrenergic activity.
