KVest Data

Grant creates a 1-2-3-4 swing patter (pelvis, torso, upper arm, hand).  Pelvic deceleration time is 109 milliseconds.  Torso deceleration time is 99 milliseconds.  The torso is counter rotated –45.44 degrees at first move while the pelvis is counter rotated -42.11 degrees at first move.  The X-factor stretch (hip/shoulder separation) is -8 degrees at first move and -7 degrees at contact.

Speed Gains:

Pelvis to Torso: 291 deg/sec.

Torso to Upper Arm: 261 deg/sec.

Upper Arm to Hand: 707 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: 102-105%

Z-Front: 245-344%

X-Back: 18%

X-Front: 46-58%

Torque- Back: 7.4-10N

Torque- Front: 142-191N

Rate of Force Development (Vertical): 385 milliseconds

Rate of Force Development (Horizontal): 130 milliseconds

Rear Foot Pressure: Whole

EFFICIENCIES
