The effects of exercise on the blood pressure and pulse were investigated among 143 students of The Hiroshima Bunka Women's Junior College. The bicycle ergometers of Kombi Aerobic No.710 & 800 were employed. The Omron electric degital manometer HEM 802F was used for the measurement of blood pressure and pulse of the left for finger. They were measured on 0, 3, 5, 7 and 10 minutes in each after the start of exercise. The following results were oftained. 1) The changes of blood pressure of the 57% among the all members of subjects reached to the maximal level within 7 minutes after the start of exercise. Four types were observed on the relationships between the maximal and the minimal blood pressure. a) The increse of the maximal blood pressure was followed by the increse of the minimal blood pressure. b) The increase of the maximal blood pressure was followed by the decrense of the minimal blood pressure. c) The maximal blood pressure decreased, but the minimal blood pressure increased. d) Both the maximal and minimal blood pressure decreased. 2) On the variation of the pulse, 57% of the subjects reached to the maximal level within 7 minutes after the start of exercise, and 37% of the subjects reached to the maximum within 10 minuts.
