Randomized Controlled TrialErgogenic effect of varied doses of coffee-caffeine on maximal aerobic power of young African subjects.
Caffeine one of the readily available stimulants consumed daily by more than 80% of the world's population, making it the most widely consumed drug in history. The objective of this study was to determine the effects of different doses (5, 10 &15 mg.kg(-1)) of caffeine per kilogram body weight on maximal aerobic power of normal young black African (Nigerian) male adults. ⋯ It was concluded that caffeine dose of up to 15mg/kg seems not to have any ergogenic effect on maximum aerobic power of young black African male adults.
