Excellent coaching cue Mike, I think it important emphasise apply force to the ground during drills…some athletes look pretty during drills and do no apply force on the downward movement…this is an opportunity to learn the proper taechnique….and how to apply more force to the track.
I could not disagree anymore.
1st. When sprinting or doing drills the foot lands ahead of the COM so hitting the ground harder or with more force will still result in breaking forces. You cannot apply force to the track in a positive way with your foot ahead of your COM, so there is no way the B drill is great for teaching technique.
2nd. The "opening up" of the lower leg in sprinting is more the result of a violent change of directioning than a forcefull acceleration of the thigh down. Therfore trying to duplicate the action with B drills (when there is no quick foward drive of the flexed leg) is a waste of time.
