Sled training vs. sprints: which boosts runner performance more?
NCT ID NCT06729138
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 80 runners to see if adding resisted sprint training with a sled (pulling a weight) improves running economy, speed, and biomechanics more than regular sprint training alone. Participants trained twice a week for eight weeks. The goal is to find better ways for distance runners to train.

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Resisted sprint training using a sled
What this could lead to
If it works, this could help coaches and runners choose better training methods to improve running economy and speed.
What could go wrong
This is a small, completed study with only 80 runners from one region, so results may not apply to all runners. It measures performance markers, not real race outcomes.
