Could smaller soccer fields create sharper players?
NCT ID NCT07755358
First seen Aug 10, 2026 · Last updated Aug 14, 2026 · Updated 4 times
Summary
This trial tests whether adding small-sided games—like 2v2 and 3v3 matches on reduced pitches—to regular training can boost aerobic endurance and passing accuracy in adolescent soccer players. Eighteen male players aged 17-18 will be split into two groups: one doing small-sided games three times a week for eight weeks, and a control group sticking to routine training. Researchers will measure endurance with a shuttle-run test and passing with a timed accuracy drill before and after the program to see if the small-sided approach makes a difference.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Small-sided games training (structured 2v2, 3v3, and 4v4 soccer drills)
- What this could lead to
- If effective, this training approach could offer a time-efficient way to boost both fitness and passing skills in young soccer players.
- What could go wrong
- This is a small, early-stage trial with only 18 participants, so results may not apply broadly. The training is physical and carries a risk of injury, though participants with recent injuries were excluded.
