NCT ID NCT07325084
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study follows 400 Swedish elite football players (academy and professional) for up to 5 years to understand how physical fitness, training load, and other factors relate to injury risk and success. Researchers will measure endurance, strength, speed, and neuromuscular control at regular intervals and track injuries. The goal is to develop better screening tools and return-to-sport guidelines.

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to better injury prevention strategies and return-to-sport tests for football players.
- What could go wrong
- This is an observational study, not a treatment trial. It will not directly cure or prevent injuries, and results may not apply to non-elite players.
