15-20 trained bodybuilding athletes were divided into caffeine gum trial (CAF) and placebo trial (PL) with a randomized, double-blind study design. The participants chewing either caffeine Gum (CAF trial, containing 5 mg/kg of caffeine) or placebo gum (PL) for 10 minutes. After rested for 15 minutes, Participants used the bicycle to adjust the pedal resistance and speed according to their own feelings until they were dehydrated to 2% of their original body weight.
The purpose of this study was to investigate the effect of caffeinated chewing gum on dehydration ability in bodybuilding athletes. Methods: 15-20 trained bodybuilding athletes were divided into caffeine gum trial (CAF) and placebo trial (PL) with a randomized, double-blind study design. The participants chewing either caffeine Gum (CAF trial, containing 5 mg/kg of caffeine) or placebo gum (PL) for 10 minutes. After rested for 15 minutes, Participants used the bicycle to adjust the pedal resistance and speed according to their own feelings until they were dehydrated to 2% of their original body weight. Record time from exercise to completion of dehydration, heart rate, HRV, energy expenditure, fat oxidation rate and carbohydrate oxidation rate.
