Numerous studies have recorded the benefits of exercise to cardiovascular responses, pulmonary function and body composition. Sedentary lifestyle can lead to the degradation of cardiovascular responses. Another factor that may influence the effect of exercise is gender, but less supportive data have been documented. Therefore, the purpose of the study was to compare the effects of aerobic exercise on resting heart rate (RHR), resting systolic blood pressure (SBP), and resting diastolic blood pressure (DBP) between male and female among sedentary individuals. The secondary objective was to determine the relationship between pulmonary function ((force vital capacity (FVC) and body composition (percentage of body fat (PBF) and fat free mass (FFM)) among sedentary individuals. Thirty sixth healthy individuals (17 males and 19 females) performed aerobic exercise on a stationary cycle ergometer with moderate to vigorous intensity 40% to 85% of heart rate reserve (HRR) and the duration of cycling exercise was 30 minutes to 40 minutes. The individuals required to follow all the training given 3 times per week for 4 weeks. FVC, PBF, and FFM measurements were taken during pre-test while RHR, resting SBP, and resting DBP were taken during pre-test and every week of exercise intervention. There was a significant difference over time on RHR, resting SBP, and resting DBP on exercise between male and female (p < 0.001). However, RHR, SBP, and DBP showed no significant difference between male and female in the effect of exercise (p > 0.05). The finding also showed that there was no correlation between the FVC and PBF (r =-0.10, p = 0.56) and FFM (r = 0.02, p = 0.91). In conclusion, aerobic exercise will improve the cardiovascular responses for both gender and no relationship between pulmonary function and body composition among sedentary students, perhaps due to there have a similar fitness level at the baseline. © JPES.
