Effect of Resisted Sled Sprints in Sprint Start and Acceleration Performance: Preliminary Results

Abstract

The purpose of the study was to examine the effect of resisted sled sprints (RSS) on the biomechanical parameters of the first steps of short acceleration sprints. Five track and field athletes performed 10-m sprints using the semi-standing (SSS) and the 3-point (TPS) starting techniques. The RSS condition was conducted with a load of 9.7% ± 0.3 of body mass. Results of the 2 (start technique) × 2 (loading) × 3 (steps) revealed significant (p .05) were evident for flight time and sled pulling force. In conclusion, regardless of the starting technique, RSS should be controlled the avoidance of the excessive loading that was observed at the sprint start.
