Abstract: (66 Views)
Introduction: Caffeine is one of the most widely used stimulants among athletes, which can be associated with increased performance. Therefore, the aim of this study was to evaluate the response of aerobic and metabolic function to acute caffeine consumption under dehydration in active men.
Method: 30 male athletes with a mean age of 26.6 ± 3.9 years in dehydration participated in this study voluntarily. Subjects were divided into three groups: caffeine consumption group (n = 10), placebo group (n = 10) and control group (n = 10). Caffeine group consumed 6 mg /kg body weight of caffeine. Sixty minutes later, the subjects performed a series of increasingly exhausting exercise activities. Blood samples were collected and blood pressure was measured before, immediately after and 24 hours after exercise. This study was performed as a two-way blind and the analysis of variance test with repeated measures (group * time) and one-way analysis of variance test were used for statistical calculations.
Results: The results showed that caffeine consumption improves aerobic function and increases carbohydrate metabolism. The rate of fat metabolism in the sham group was significantly higher than the control group (p≥0.05). But there was no significant difference in fat metabolism between placebo and caffeine groups (p <0.05).
Conclusion: It seems that caffeine consumption in exhausting sports activities in hot environments and dehydration conditions improves aerobic function and increases metabolism.
