Purpose: Diabetes Mellitus (DM) is correlated with a group of diseases related to the metabolism
of glucose that is increasingly affecting the population, being considered a public health
problem. Exercise increases absorption of glucose by the muscles during, pre- and post- periods of effort,
therefore, it is an excellent treatment strategy to maintain the glycemic control of diabetic patients.
Caffeine intake enhances Ca2+ concentration in β pancreatic cells, affecting insulin secretion.
Materials and Methods: Systematic review with a sample of six scientific papers published in academic
journals. Only studies involving soccer players (professionals and amateurs, except goalkeepers)
were included in this review.
Results and Conclusion: Studies included in this review concluded that caffeine might act in several
ways in glucose metabolism; however, more researches are necessary to elucidate the real effects of
this compound in the organism.
