A Kinematic Analysis of Three Best 100m Performances Ever

I like reading this Journal of the study of the kinematics erm... I like the statistical analysis they provide in the form of a graph and table of the stride length, stride frequency, speed of usain bolt compared with the finalists at the race.

Usain bolt has a lower stride frequency than the others, but a bigger stride length which is at it's biggest  in the end, which doesn't make sense, as he is maintaining speed after 60m he is still increasing stride length.

he has a stride frequency of 11.2 in the first 20m mean in the three races, 2008, 2009, 2012

Warm up drills
   - a walk, b skip quick powerful switch (heel to hams focus), a runs, dribbles small to big to run, straight leg to runs (force, reflex, go up/forward). force to hit the ground before it hits the ground knee/hip is at 90 degrees.
   - acceleration: low heel recovery, shin angle low, drive legs back before hitting the ground and drive thighs/knee forward not up
-------------------------------------------------------------
Measuring reminder:
5 toe to heel steps = 148cm

Arm also aids the legs in driving it down with power - seifullaah73
