KVest Data

Jack presents as a 1-2-3-4 swing pattern (pelvis, torso, upper arm, hand).   The pelvic deceleration time is 134 milliseconds.  Torso deceleration time is 96 milliseconds.  The torso is counter rotated -36.45 degrees at first move, while the pelvis is counter rotated -10.88 degrees at first move.  The X-factor stretch (hip/shoulder separation) is -25.56 degrees at first move and -21.26 degrees at contact.

Speed gains:

Pelvis to Torso: 356 deg/sec.

Torso to Upper Arm: 130 deg/sec.

Upper Arm to Hand: 559 deg/sec.

Force Plate Data

Z-axis is the vertical force produced (up & down : in % of body weight)

X-axis is the horizontal force produced (back to front : in % of body weight)

Torque is rotary force in the ground (in Newtons (N) of force)

Rate of Force Development (Vertical): 159 milliseconds 

Rate of Force Development (Horizontal): 125 milliseconds

Rear Foot Pressure: Ball
