Abstract
Objective: To assess the aerobic capacity in offspring of hypertensive versus normotensive parents. Background: Cardiovascular reactivity to exercise has been investigated in the offspring of HTP in a few studies, but not much done to determine aerobic capacity. This study aims to investigate aerobic capacity and effects of parental hypertension in the children of hypertensive parents through a physical test i.e., 6 minute walk test. Study Design: Comparative study. Methods: The ethical clearance was taken from the college and consent was taken from the 30 subjects (offspring of hypertensive and normotensive parents) taken into consideration using 6 minute walk test. The comparison is done on the basis of physiological parameters mainly as 6MWD, VOâ‚‚ Max, Pre and Post outcome measures were taken and VO2 max was calculated using formula VO2 max (mL⋅kg−1⋅min−1) = 70.161 + (0.023 × 6MWT [m]) – (0.276 × weight [kg]) – (6.79 × sex, where m = 0, f = 1) - (0.193 × resting HR [beats per minute]) – (0.191 × age [y]). Results: The results of present study have shown significant difference in cardiovascular parameters like post SBP, pre and post DBP, 6 minute walk distance and VO_2MAX between Group A (normotensive offspring of hypertensive parents) and Group B. Comparing the values of Group A (normotensive offspring of hypertensive parents) and Group B (normotensive offspring of normotensive parents).There is significant difference between post SBP (129.8±3.6 in group A and 123.47±4.7 in group B), pre DBP with mean value (84.27±4.5 and 78.00±4.1) and post DBP with mean value (90.40±3.8 and 79.73±4.1) in Group A and Group B respectively. There is significant difference in mean values of 6 minute walk distance (530.93±22.0 in Group A and 698.13±25.2 Group B) and VO_2MAX between Group A (41.91±1.8) and Group B (49.01) respectively Conclusion: There is decrease in physical fitness and increase in blood pressure to exercise test in Group A subjects compared to Group B subjects therefore offspring of hypertensive parents with increased BP and decreased physical fitness levels should be considered as high risk group for development of future cardiovascular events.
