Technical Details

  • Variable Type: Discrete Metric
  • Data Type: Boolean
  • Units: True/False
  • Column Name: forearm_flyout
  • Measurement: Elbow angle at foot contact and ball release
  • Threshold: Elbow angle < 75° at foot contact AND < 20° at ball release (where full extension = 0°)

​
Description

Forearm flyout is a binary indicator that flags excessive elbow extension prior to ball release. It occurs when the elbow angle is less than 75 degrees at foot contact and less than 20 degrees at ball release. Elbow angle is measured with full extension = 0°, thus lower joint angles are more extended.
