conference paper description
Caffeine is used widely by athletes as an ergogenic aid. Caffeine improves performance by enhancing anaerobic exercise capacity and power output. PURPOSE: The purpose of this study was to examine the effects of caffeine on anaerobic power in Division III female ice hockey players. METHODS: Ten collegiate Division III female ice hockey players were recruited to participate (age: 20 ± 1 yr, height: 166 ± 6 cm, weight: 71 ± 10 kg, and body composition: 30 ± 5-%). Subjects completed two Wingate test protocols in a randomized order. The subjects consumed either the CAF (120 mg) or the PLA (3 mg) 1 h prior to each test. The Wingate test protocol consisted of three 30 s bouts of maximal sprint pedaling with a 2 min rest interval between each sprint. The resistance was equivalent to 7.5% of body weight. Peak anaerobic power (PP), mean anaerobic power (MP), and fatigue index (FI) were calculated and recorded. RESULTS: There were no significant differences in PP, MP, or FI following the consumption of CAF or PLA (PP: CAF = 510.25 ± 27.03W vs PLA = 498.76 ± 24.54W; MP: CAF = 365.83 ± 13.29 vs PLA 368.67 ± 14.05W; FI: CAF = 47.46 ± 1.79 vs PLA = 47.43 ± 3.55%, p > 0.05). CONCLUSION: The consumption of CAF one hour prior to exercise showed no significant improvements in anaerobic performance. A higher dosage of CAF may have resulted in enhanced anaerobic exercise capacity and power output.
