Abstract



The objective of this study was to determine the effect of 5mg/kg body weight dose of caffeine on cardiovascular system of normal young adult males of Black African Origin. Twenty normal young adult male volunteers participated. A repeated measures 2 randomized Crosse over (counter balanced) double blind design was used in data collection. One hour post caffeine ingestion of varied doses (5mg/kg body weight) and placebo dose cardiovascular (SBP, DBP & HR) parameters were assessed. Repeated measures t-test was used to assess the level of significance in all variables of interest. The result showed no significant effect of varied doses (5mg/Kg) of caffeine over placebo in all cardiovascular parameters assessed at P<0.05. It was concluded that instant soluble coffee (Caffeine) dose up to approximately 3199mg (300mg caffeine) seems not to stress the cardiovascular system of normal young black African adults.
