Abstract

Numerous studies on aerobic exercise training have been widely employed for several years to improve cardiovascular risk factors in both healthy adults and those with cardiovascular disease. However, contradictory results were reported in normotensive subjects as well as the intensity that might lead to the decrease in resting values of cardiovascular parameters (CVP). To determine the effect of aerobic exercise of varied intensities on selected cardiovascular parameters among normotensive adult college students. Thirty two male subjects of 28.4 ± 1 years were randomized in to four groups: High intensity group (HIG), moderate intensity group (MIG), low intensity group (LIG) and control group (COG). The following parameters were measured at baseline and post-exercise (6-weeks). Systolic blood pressure (SBP), diastolic blood pressure (DBP), resting heart rate (HR), and estimated maximal oxygen consumption (VO2 max). Post-aerobic exercise effects on decrease resting values of CVP were observed: SBP (F[3,25] = 8.9, P<0.05), DBP (F[3,25] = 17.5, P<0.05), HR (F[3,25] = 10.7, P<0.05), RPP (F[3,25] = 5.4, P<0.05), and VO2 max (F[3,25] = 27.6, P<0.05). Sheffe post hoc analysis indicates that both HIG and MIG significantly differ from control group with respect to SBP (P<0.05), while HIG significantly differ from control group in DBP, HR, RPP and improvement of VO2 max. Aerobic exercise of higher intensity may likely result or yield greater reduction in the resting values of cardiovascular parameters in normotensive adults.
