Then same parameters were recorded at various time intervals after Queens College Step Test to find the recovery time of cardiovascular system.Result: There were no significant difference in mean basal HR, SBD and DBP between the groups. HR, SBP and DBP were almost same at various time interval after Queens College Step Test, except at time interval 5 sec. – 20 sec. where DBP was significantly higher in habitual caffeine drinkers compared to non habitual caffeine drinkers.Conclusion: From this study it has been concluded that caffeine doesn’t causes any harmful effect on cardiovascular system.
