Abstract

INTRODUCTION: Caffeine (CAF) is a central nervous stimulant and is one of the most popular ergogenic aids due to its positive effect on exercise. PURPOSE: The purpose of the current study was to determine the effects of CAF on the various energy systems in the body, including the ATP-PCr, anaerobic glycolysis, and aerobic systems.  METHODS: 10 physically active subjects participated in the study (Age: 21 ± 2 year, Height: 172.2 ± 11.7 cm, Weight: 75.7 ± 20 kg, Body Fat % 21.2 ± 7.7%).  Subjects completed the vertical jump (VJ), Wingate anaerobic test (WAnT) and VO2max test, after consuming 100 mg of a CAF gel and a placebo (PLA).  The CAF or PLA was consumed 1 hr prior to the exercise testing session. RESULTS: There was a significant difference between the fatigue index (FI) during the WAnT (p < 0.05, CAF: 57.9 ± 17.9%, PLA: 71.3 ± 10.5%).  There were no significant differences between CAF and PLA supplements for anaerobic or aerobic variables (p > 0.05). CONCLUSION:  The current research showed CAF had little impact on performance. However, there was a significant difference in FI, suggesting CAF allowed the subjects to hold a higher maximum wattage for a longer period.
