Summary

This study looked at how a dose of caffeine (6mg per kg of body weight) affects the way healthy adults perform exercises like running, squatting, and jumping, both when fresh and when tired. Researchers measured angles, forces, and timing to see if caffeine changes movement technique. The goal is to understand if caffeine's performance boost comes with trade-offs, like increased injury risk.

What this could mean

Active substance: caffeine
What this could lead to: If successful, this could help athletes and coaches understand whether caffeine improves or harms movement technique, potentially reducing injury risk.
What could go wrong: This is a small, completed study with only 15 healthy participants, so results may not apply to the general population or athletes in real-world settings.
