KVest Data

Isaac creates a 2–1-3-4 swing patter (torso, pelvis, upper arm, hand).  Pelvic deceleration time is 130 milliseconds.  Torso deceleration time is 140 milliseconds.  The torso is counter rotated -30.01 degrees at first move while the pelvis is counter rotated -34.18 degrees at first move.  The X-factor stretch (hip/shoulder separation) is –17.33 degrees at first move and -11.56 degrees at contact.

Speed Gains:

Pelvis to Torso: 260 deg/sec.

Torso to Upper Arm: 175 deg/sec.

Upper Arm to Hand: 949 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: 99-103%

Z-Front:184-199%

X-Back: 16-17%

X-Front: 79-90%

Torque- Back: 15N

Torque- Front: 154-169N

Rate of Force Development (Vertical): 125 milliseconds

Rate of Force Development (Horizontal): 130 milliseconds

Rear Foot Pressure: Ball of Foot

EFFICIENCIES

• X-factor stretch
• Upper arm to hand speed gain
• Overall ground force production (lead leg)

Defficiencies

• Out of sequence
• Overall pelvic speed
• Torso to upper arm speed gain
• Vertical force spike (rear leg)
