KVest Data

Ryland creates a 1-2-3-4 swing patter (pelvis, torso, upper arm, hand).  Pelvic deceleration time is 93 milliseconds.  Torso deceleration time is 125 milliseconds.  The torso is counter rotated –44.49 degrees at first move while the pelvis is counter rotated -24.11 degrees at first move.  The X-factor stretch (hip/shoulder separation) is -18.73 degrees at first move and -23.21 degrees at contact.

Speed Gains:

Pelvis to Torso: 165 deg/sec.

Torso to Upper Arm: 264 deg/sec.

Upper Arm to Hand: 838 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)

Z-Back: 103%

Z-Front: 174%

X-Back: 14%

X-Front: 71%

Torque- Back: 49N

Torque- Front: 151N

Rate of Force Development (Vertical): 204

Rate of Force Development (Horizontal): 193
