First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether sprinting with a light sled (resisted) or without resistance (unresisted) improves sprint speed and jumping ability more in young male footballers aged 13-17. Forty-four players did two sessions per week for six weeks. The goal was to see which training method leads to better sprint and jump performance.
