Quizplus · Accepted Answer

The most reliable way of assessing whether athletic performance is boosted by caffeine consumption is through experimentation. This involves manipulating the independent variable, in this case caffeine consumption, and measuring the effects on the dependent variable, athletic performance. Randomly assigning participants to different conditions and controlling for extraneous variables allows for the most accurate assessment of the effects of caffeine on athletic performance. Surveys, case studies, and naturalistic observation may provide some insight, but they are not as controlled and may be subject to biases and limitations.
