A practical pitching mechanics video checklist.
Use this checklist to structure a conversation around visible video. Do not use it to diagnose injury, calculate workload, or replace a qualified pitching coach or clinician.
Set position and balance
Note the pitcher’s starting constraints, intent, view, and whether the full delivery is visible. Inspect balance without assuming one appearance fits every athlete.
Leg lift and movement toward the plate
Review visible head and trunk control, direction, tempo, and how the athlete moves into the stride.
Hand break and foot strike
Compare the sequence around hand separation and lead-foot contact. Camera angle and frame rate can shift the apparent timing.
Trunk and arm position
Inspect the visible relationship between the trunk, shoulders, throwing arm, and stride. Avoid treating a single frozen arm shape as a complete mechanics judgment.
Release and follow-through
Bracket the release neighborhood and continue through deceleration. Direction and balance after release can add context to the release frame.
When video is not enough
Use qualified assessment and appropriate hardware for pain, injury risk, workload, velocity, spin, movement, or exact three-dimensional metrics.
