A tired mind may drag down your jump — can the right focus lift it back?
NCT ID NCT07779304
First seen Aug 21, 2026 · Last updated Aug 21, 2026
Summary
This study asks whether short-term mental fatigue and different coaching cues affect vertical jump height. Thirty-two physically active university students will jump after either a 30-minute mentally tiring computer task or a relaxing video, while receiving different focus instructions. The goal is to see how mental tiredness and attentional focus influence performance, which could help coaches design better training strategies.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Mental-fatigue protocol (Stroop task) and attentional focus instructions
- What this could lead to
- If mental fatigue and focus cues affect jump height, coaches could tailor training and competition prep to optimize performance.
- What could go wrong
- This is a small, early-stage study in healthy students; results may not apply to all athletes or real-world settings.
