Background: The study was to examine the effect of step aerobic training (SAT) and floor aerobic training (FAT) on resting heart rate in sedentary women. Methodology: Subjects were randomly assigned to step aerobic training (n=15), floor aerobic training (n=15) and control group (n=15). The subjects in the experimental groups performed scheduled aerobic training 3 times a week for 12 weeks. The heart rate monitor was used to measure resting heart rate. The test was conducted before and after initiation of the training programme to determine the effect training. Analysis of Variance (ANOVA) and Scheffe’s Post –hoc Test was used for analysis of the results. Result: Compared to the control group; resting heart rate was significantly decreased in both experimental groups. Conclusion: According to the obtained results, SAT and FAT had beneficial effects on the resting heart rate, other than SAT have relatively more effective in resting heart rate as compared to FAT group.
