Summary

This study looked at whether short daytime naps help adolescent soccer players perform better. Sixteen male players from a Turkish club tried no nap, a 25-minute nap, or a 45-minute nap before agility and sprint tests. The 45-minute nap improved agility and made exercise feel easier, but did not help with repeated sprints. The findings suggest strategic napping could be a simple way to boost certain aspects of performance.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
strategic napping (25-minute or 45-minute nap)
What this could lead to
If successful, this could help coaches and athletes use short naps to boost agility and reduce how hard exercise feels during training or competition.
What could go wrong
This was a very small study with only 16 male soccer players, so results may not apply to other groups. The naps did not improve fatigue resistance, so benefits are limited.
