I did a run gait analysis with Hanna today and got pretty good results. We strapped a Stryd power meter to her show to not only get visual improvement in her stryd, but also some hard, objective numbers. Here are what some of the numbers that a Stryd power meter gives:
Power – energy in watts
Horizontal power – % of power that is producing foward motion
Running Effectiveness – how effiicent someone is turning watts into speed
Stride Length – distance (in meters) covered between steps in meters
Vertical Oscillation – distance (in centimeters) that the center of mass goes up during a stride.
