Effect of Blood Pressure Elevation Level during Graded Exercise Test on the Factors Causing Hypertension

&nbsp;&nbsp;It is well established that the elevation of systolic blood pressure during exercise is the risk factor for cardiovascular diseases. The objective of this study is to examine whether the elevation of systolic blood pressure during exercise is correlated with the pathogenesis of hypertension. To fulfill this objective, this study assigned 31(46.2±7.0 yr) middle-aged women to low group(n=l7) and high group(n=14) according to the criteria for the classification of hypertension(JNC-Ⅵ, 1997). Following this, this study analyzed cardiovascular factors(SBP, DBP, HR, VO₂, RER) and blood components(LDLC, HDLC, TC, TG, HDLC/LDLC). The results of the present study were as follows: (1) SBP was significantly increased at resting state, at 4 minutes, at 6 minutes and at endpoint(p＜.05), (2) There was significant difference between SBPmax and SBPrest(p＜.05), (3) DBP was significantly increased solely at resting state SBPmax (p＜.05), (4) RER was significantly increased at 10 minutes. In addition, a statistical analysis revealed that SBPmax-SBPrest was significantly correlated with age(r=0.336), SBPmax(r=0.827) and DBPmax(r=0.335).<BR>&nbsp;&nbsp;In conclusion, this study indicates that the monitoring of such cardiovascular indicators as SBP, DBP, HR, VO₂ and RER is essential in health promotion in patients with obesity or normal healthy people as well as patients with hypertension.
