Disordered caffeination: a biocultural analysis of adverse reactions to caffeine
Title
Disordered caffeination: a biocultural analysis of adverse reactions to caffeine.

Abstract/Description
While coffee culture has long since been positively associated with intellectual and working life, the health and safety of its primary stimulant, caffeine, has recently fallen under scrutiny by the FDA. This medical anthropology thesis provides a biocultural synthesis of caffeine culture, health effects, and biological variation in adverse effects related to pharmacodynamics and pharmacokinetics. Supporting evidence for variation in responses to caffeine was found through surveying 100...
Show moreWhile coffee culture has long since been positively associated with intellectual and working life, the health and safety of its primary stimulant, caffeine, has recently fallen under scrutiny by the FDA. This medical anthropology thesis provides a biocultural synthesis of caffeine culture, health effects, and biological variation in adverse effects related to pharmacodynamics and pharmacokinetics. Supporting evidence for variation in responses to caffeine was found through surveying 100 participants, investigating caffeine consumption levels, perceptions and health beliefs, adverse effects experienced, and medical encounters. Increased rates of adverse effects were found for students, pharmaceutical and over-the-counter drug users, and for participants reporting negative or ambivalent perceptions of caffeine, intolerance, or sensitivity to caffeine. Variation in rates of adverse effects suggests biocultural interactions account not only for patterns in pharmacological data, but are also clinically significant in constructing risk of caffeine intoxication.

effects of caffeine supplementation on strength and muscular endurance in resistance-trained women
Title
The effects of caffeine supplementation on strength and muscular endurance in resistance-trained women.
Creator
Goldstein, Erica R., College of Education, Department of Exercise Science and Health Promotion
Abstract/Description
The purpose of this study was to determine the acute effects of caffeine supplementation on strength and muscular endurance in resistance-trained women. In a randomized manner, 15 women consumed caffeine (6 mg/kg) or placebo (PL) seven days apart. Sixty minutes following supplementation, participants performed a one repetition maximum (1RM) barbell bench press test and repetitions to failure at 60% of 1RM. Heart rate and blood pressure were assessed at rest, 60 minutes post-consumption, and...
Show moreThe purpose of this study was to determine the acute effects of caffeine supplementation on strength and muscular endurance in resistance-trained women. In a randomized manner, 15 women consumed caffeine (6 mg/kg) or placebo (PL) seven days apart. Sixty minutes following supplementation, participants performed a one repetition maximum (1RM) barbell bench press test and repetitions to failure at 60% of 1RM. Heart rate and blood pressure were assessed at rest, 60 minutes post-consumption, and immediately following completion of repetitions to failure. Repeated measures ANOVA indicated a significantly greater bench press maximum with caffeine (p<0.05) (52.9 « 11.1 kg vs. 52.1 « 11.7 kg) with no significant differences between conditions in 60% 1RM repetitions (p=0.81). Systolic blood pressure was significantly greater post-exercise, with caffeine (p<0.05) (116.8 « 5.3 mmHg vs. 112.9 « 4.9 mmHg). Our findings indicate a moderate dose of caffeine may be sufficient for enhancing strength performance in resistance-trained women.
