Final answer:
A double-blind study was conducted to test the effect of caffeine on the rate of finger tapping in highly trained male cyclists in a hot environment.
Step-by-step explanation:
A double-blind study was conducted to test the effect of caffeine on the rate of finger tapping in highly trained male cyclists in a hot environment. The study involved thirty college men who were randomly assigned to three groups and given different doses of caffeine (0 mg, 100 mg, or 200 mg). Two hours after consuming the caffeine, the rate of finger tapping per minute was measured. The experiment was double-blind, meaning neither the participants nor the recorders knew which group they were in.
The purpose of the study was to determine whether caffeine affected the rate of tapping and, if so, how. The data collected from the study would provide insights into the potential benefits or drawbacks of consuming caffeine for highly trained cyclists in hot environments.
