What is BEST to say about a runner who is running at a constant velocity?

Sprinting involves a quick acceleration phase followed by a velocity maintenance phase. During the initial stage of sprinting the runners have their upper body tilted forward in order to direct ground reaction forces more horizontally. As they reach their maximum velocity the torso straightens out into an upright position. The goal of sprinting is to reach and maintain high top speeds to cover a set …

Tue Dec 20 2011 13:30:00 GMT-0500 (Eastern Standard Time) · When running at a constant speed it has been found that stride frequency increases during incline vs. level running with a concomitant decrease in stride length. At a speed of 30 meters/second Gottschall and Kram noted an increase in stride frequency from 1.45±0.06 Hz to 1.51±0.07 Hz at an incline of 9 degrees (15.8%).

The team collected metabolic and mechanical data by indirect calorimetry and ground reaction force measurements on Pistorius’s performance during constant -speed level treadmill running a…
