What are the key strength metrics that correlate with velocity?Updated 2 months ago

Several strength metrics have been identified as key contributors to higher velocity:

  • Internal Rotation (IR) Strength – More IR strength contributes to faster arm acceleration.

  • External Rotation (ER) Strength – Strong ER muscles stabilize the shoulder and allow for controlled deceleration.

  • ER/IR Ratio – Maintaining a balanced ratio (ideally a 1 to 1 ratio) reduces injury risk and improves efficiency.

  • Grip Strength – Enhances forearm stability and force transfer.

  • Scapular Stability & Posterior Chain Strength – Essential for power generation and preventing compensatory stress on the arm.
