Finally, Anderson et al. [26]

reported a significant improvement in time among trained oarswomen for a 2,000 m row, following what is considered to be a high dose of caffeine (9 mg/kg). As suggested, the design and population of women studied in relation to caffeine supplementation is varied. In addition, there are no investigations in the available literature that report any outcomes related specifically to GANT61 mw resistance-trained females. Therefore, the purpose of this study was to determine the acute effects of caffeine supplementation on strength and muscular endurance in resistance-trained women. Methods Research Participants Fifteen resistance-trained females volunteered to serve as research participants for this investigation.

Inclusion criteria stipulated DNA Synthesis inhibitor that all subjects were between the ages of 18-45 and had participated in resistance Sepantronium supplier training activities at least 3-5 days per week for the 6 month period immediately prior to enrollment in this study. Other inclusionary criteria included the ability to bench press 70% of individual body weight. All testing procedures were verbally explained in detail and subjects provided written informed consent prior to participation, in accordance with the guidelines established by the Institutional Review Board at a southeastern university. Study Protocol A double-blind, placebo-controlled, cross-over design was utilized in this investigation. Research participants were asked to attend three laboratory sessions. The first session was for familiarization, followed by two testing trials seven days apart using the same testing protocol. Either caffeine at a dose of 6 mg/kg or placebo (PL) was administered orally 60 minutes prior to testing, in randomized order (See Supplementation Protocol Section). Research participants were directed to continue the same general lifestyle patterns of exercise and nutrition intake during each seven-day period prior to the two exercise testing sessions. To verify the consistency many of diet, the subjects were directed to complete a 3-day dietary recall (two week days

and one weekend day) for each week prior to testing. The dietary intake data were analyzed using ESHA Food Processor SQL dietary analysis software (ESHA Research, Salem, OR). All research participants completed one familiarization session prior to participating in the two testing trials. During the familiarization session, the participants were instructed on proper technique and mechanics of the bench press exercise, according to the standard methods defined by Baechle and Earle [27] and the National Strength and Conditioning Association. Additionally, participants performed a series of lifts to determine their ability to bench press 70% of individual body weight. On test days, participants were asked to report to the testing laboratory in the morning after a 12-hour period without food.
