First seen Jun 27, 2026 · Last updated Jul 01, 2026 · Updated 2 times
Summary
This study looks at whether a 90-minute afternoon nap, a moderate dose of caffeine, and a short recovery routine (stretching plus a snack) can improve evening athletic performance. Sixty elite university athletes (30 men, 30 women) will try different combinations of these strategies in a randomized, double-blind, placebo-controlled crossover trial. The goal is to see which combination works best and whether effects differ between sexes or morning-type versus evening-type people.
