Improved Performance in National-Level Runners With Increased Training Load at 1600 and 1800 m.

abstract：BACKGROUND:Sprint running acceleration is a key feature of physical performance in team sports, and recent literature shows that the ability to generate large magnitudes of horizontal ground-reaction force and mechanical effectiveness of force application are paramount. The authors tested the hypothesis that very-heavy...
