Summary

This study looks at whether taking 300 mg of caffeine can help healthy male athletes perform better on cognitive tests and a 4-km cycling time trial in the morning. Fifteen participants will be tested under three conditions: caffeine, placebo, and no pill. The goal is to see if caffeine can offset the natural dip in morning performance.
