Effects of Different Sled Loads on Sprint and Neuromuscular Performance in Young Male Football Players: An 8-Week Periodized Field Study
Sponsor: Bitlis Eren University
Summary
The purpose of this 8-week periodized field study is to investigate and compare the acute and chronic effects of three different sled towing loads (10%, 15%, and 20% of body weight \[BW\]) on sprint performance (5m, 10m, 15m) and neuromuscular characteristics (Squat Jump \[SJ\], Countermovement Jump \[CMJ\], Drop Jump \[DJ\], and Reactive Strength Index \[RSI\]) in trained male youth football players aged 13-14 years. While all other training variables (distance, frequency, volume, and rest intervals) are standardized, this study aims to identify the optimal sled load that enhances acceleration and horizontal force production without compromising running mechanics during a critical pediatric athletic development window.

Interventions
Resisted Sled Sprint Training
An 8-week periodized resisted sprint training protocol using weighted sleds. Sessions are performed twice weekly over a 15-meter sprint distance, immediately following a standardized warm-up. Participants are assigned to sled towing loads equivalent to 10%, 15%, or 20% of their individual body weight (BW). Training volume progresses systematically from 2 sets of 3 repetitions (Weeks 1-2) to 3 sets of 4 repetitions (Weeks 7-8) with 2 minutes of inter-repetition rest and 3 minutes of inter-set rest.
