title: [Arterial pressure changes during exertion in the normal subject].
abstract: The exercice electrocardiogram, carried out in 160 normal subjects, has allowed us to witness the physiological mechanisms of adaptation to exercise as a function of age and sex. The relationship between systolic arterial pressure (SAP) and cardiac rate (CR) is very narrow (R = 0.97), and is a linear function. Its slope increases with age in both sexes, and differs significantly in the male and female (P less than 0.001). Systolic pressure is related to the relative cardiac rate (CR%) by the formula SAP = 1.55.CR% + 70.
