Bryce Harper Swing Analysis - Lower Body Power
what we can learn from inaccuracies in the Bryce Harper Swing article, Washington Post
when analysis of mechanics drivers or biomechanics is based on aesthetics it tends to focus on obvious external events, unfortunately the obvious external events very rarely coincide with important driving mechanism - the key elements of power and movement are things that we can't "see" and usually happen well before the visual event we are focused on
the good thing is that we can "measure" these key events using 3D motion capture and other tools including force plates and EMG

ZenoLink Soccer Kick Kinetic Link
Soccer kick kinetic link from an elite male collegiate player.
Sequence: Pelvis rotates rapidly in a counter clockwise direction, just
after plant leg contact with ground. Pelvis then quickly decelerates
as the kick leg hip rapidly flexes, resulting in knee flexion, loading
the quad (stretch-shorten, active eccentric load). Just before the foot
strikes the ball, hip flexion decelerates, facilitating a ballistic
knee extension of the kick leg.

ZenoLink Basketball Pound / Ball Handling Analysis
#ZenoLink Basketball Pound Animation
Pound dribbling drill to measure power and ball speed retention. Acceleration is key to creating the highest ball speed retention on rebound back to the hand. The faster the ball gets back to the hand the less time in the air and the more time the player has control of it, minimizing the ability for a defender to steal it and also maximizing control over movement and direction.
Better acceleration of the ball is a result of better dribble arm, elbow extension acceleration, which in turn is a result of core and lower body stability and power/speed transfer. The better the ball accelerates the better is reaches highest speed closer to the ground which in turn results in better rebound and return speed.

So you want to throw hard?!
Baseball pitch velocity has become a big topic of discussion these days, with the number of pitcher able to reach or exceed the 100mph mark increasing and the average pitch velocity now creeping into the 90's (where it had been high 80's).
Pitch velocity is a product of arm speed. Arm speed is a result of the coordination of elbow extension and shoulder internal rotation velocity. When coordination is optimal, shoulder internal rotation speeds can reach anywhere from 6000 deg/sec to upwards of 8000 deg/sec at ball release.

GO FAST - base stealing
How fast do you think you are? How fast could you be?
3D animation and high level biomechanical performance/injury analysis
of sprint-acceleration-base stealing, captured on the field, or in the
gym, during spring training, as part of combine testing... NO sensors,
NO wires, NO markers, JUST DATA!
