Effects Of Caffeine On Reaction Time, Peak Muscle Power, And 30 Meter Sprint Time, Kasara Mahlmeister

Culminating Projects in Kinesiology

This study aimed to determine how caffeine affects reaction time, peak muscle power calculated from vertical jump height, and 30 meter sprint time. Each individual ingested either a placebo (white flower) or 5 mg/kg of caffeine in addition to their estimated daily average caffeine consumption (mg). After 60 minutes of rest, subjects (N=15) performed a reaction time test followed by a vertical jump test and a timed 30m sprint. The dependent measures were reaction time (msec), peak muscle power (watts) calculated from vertical jump height (cm) and 30m sprint times (s). A covariate of habitual or naive caffeine users was …
