Study Of Sex Differences In Systolic Blood Pressure And Exercise In Non- Athletic Adults

Abstract

Background & Objectives: The aim of the present study was to study the sex d ifferences in Systolic Blood Pressure (SBP) responses to Exercise in healthy, non- athletic adu lt's. SBP during exercise have been found to predic t hypertension, coronary heart disease and cardiovascular disease (CVD). Materials & Methods: One hundred normal, healthy, non-smoking subjects (50 Male & 50 Female) of Dr. PSIMS& RF are selected based on healthy life style, Body mass index, rest ing blood pressure & resting heart rate. Results: Age, BMI and pre-exercise heart rate showed no significant differences between genders. During the exercise test, males showed extremely si gnificant % rise in SBP & HR than females. % HR decline in 1st min and 3rd min has got extremely statistical significance between males and females. Systolic blood pressure recovery ratio shows extremely significant increase from 1st min to 3rd min in males. The % HR decline in the 3rd min showed extremely significant increase in males when compared to females. SBP responses during and after maximal exercis e were estimated using percentage SBP rise (%SBP rise) and SBP ratio in 3 minutes of recovery relative to 1 minute (SBP R2). Males showed a significantly higher %SBP rise (34.75± 6.32; p<0.00 1) and lower SBPR2 (0.90± 0.04; p<0.001) in comparison to females. Conclusion: Exercise SBP testing provide an important clue to i dentify the subjects at risk for developing hyperte nsion
