EficÁCia ergogÊnica da suplementaÇÃo de cafeÍna sobre o desempenho de forÇa? uma anÁlise crÍtica

Abstract

Factors that improve the adaptations to strength training, especially the nutritional, have been the subject of interest from individuals practicing strength training. Due to known mechanisms of action of caffeine, studies have been undertaken in order to investigate the ergogenic potential of caffeine on strength performance. Such studies, however, are scarce, and their results controversial. Thus, the aim of this review was to bring out the potential mechanisms of action by which caffeine could exert its ergogenic effect on strength performance, evaluating the possible ergogenic role of caffeine on this activity. In general, due to the heterogeneity in experimental designs, to the varied level of habituation to the consumption of caffeine, to the differences in the physical test employed and diet preceding the physical test, we cannot attest the ergogenic effectiveness of this nutritional supplement on strength performance.
