[ABSTRACT] The present study was carried out to examine the changes in blood pressure during one hour running regulated at 10, 120, 140 and 160 beats/min. of heart rate for three young men, while two middle aged women only run with their own pace through one hour. All running test were performed through late December to early January. Blood pressure was measured every five minutes during one hour running The results obtained are summarized as follows, 1)In young men, systolic pressure(sBP) during running increased in the earlier stage of running, and then decreased gradually. The level of sBP was the highest during running at 160 beats/min. of heart rate. Diastolic pressure(dBP) declined greatly during running at 140 and 160 beats/min. of heart rate compared with those of 10 and 120 beats/min. of heart rate. In middle aged women with hypertension and normotension, heart rate during running were recorded approximately 150-160 beats/min. Systolic and diastolic blood pressure during running of a woman with hypertension was higher than those of a normotensive woman. 2)In comparing of blood pressure between during running at 160 beats/min. of heart rate in young men and those of two middle aged women, systolic and diastolic blood pressure a woman with hypertension were the highest value among them, while those of the young men in diastolic blood pressure demonstrated the largest declines among them.
