Ergogenic Effects of Caffeine Dose on Maximal Aerobic Power of Normal Nigerian Undergraduate Students

Abstract

Objective: The objective of this study was to determine the effects of 5mg/kg dose of caffeine on maximal aerobic power of normal young male African (Nigerian) adults. Method: Twenty normal young male adults volunteers participated. A repeated measure 2 randomized crossover (counter balanced) double blind design was used in data collection. Subjects engaged in 20 meter shuttle run test (20 MST) one hour Post caffeine (5mg.kg-1) and placebo doses ingestion. Endurance Performance indexes (VO2 max, run time and number of exercise laps) were recorded. Result: Repeated measures t-test was used to assess the level of significant difference between caffeine doses and placebo dose in VO2 max,run time and number of exercise laps. The result showed no significant effect of caffeine doses over placebo dose at P< 0.05. Conclusion: It was concluded that instant soluble coffee (Caffeine) dose of 5mg/kg (300mg caffeine) seems not have any ergogenic effect on max aerobic power of normal young black male African Adults.
