Running & Gait Form Analysis

Purpose

Use the running and gait tools at APOPT Form Analysis to review posture, cadence, contact timing, hip drop, joint motion, and pelvic stability. Convert one visible pattern into a simple cue and a planned retest.

How the tools are used

Capture a short side view and, when appropriate, a front or rear view. Keep the camera stable, the athlete fully visible, and the camera angle as close to perpendicular as practical. Record the surface, footwear, speed, fatigue state, and whether the movement is walking, easy running, race pace, or sprinting.

The tools can support frame-by-frame observation, cadence and contact timing, posture and joint-angle overlays, hip-drop or pelvic-stability screening, and discipline-specific running mechanics. A visible angle is a two-dimensional estimate affected by camera position, clothing, occlusion, speed, and landmark selection.

Deriving actionable insight

Use See → Ask → Cue → Retest:

• See: Describe one repeated pattern without judging it.

• Ask: Ask about intent, comfort, fatigue, pain, pace, and whether the clip is typical.

• Cue: Choose one athlete-controllable action.

• Retest: Repeat the same task and camera setup after a few trials.

Examples of proportionate coaching cues include “run tall through the hips,” “quiet, quick contacts,” or “keep the belt line level.” Do not use video alone to diagnose injury, prescribe rehabilitation, or force every athlete toward the same appearance.

75–105 minute assignment

0–15 minutes — Question and consent. Choose running or walking. Obtain video authorization. State the athlete’s goal and the one movement question you want to answer.

15–30 minutes — Capture. Record 2–3 short clips from the side and one additional angle if useful. Keep speed and camera setup consistent.

30–55 minutes — Analyze. Review posture, cadence/contact rhythm, pelvis/hip stability, and one joint-motion feature. Mark what is clearly visible, what is uncertain, and what is not measurable from the clip.

55–75 minutes — Coach. Select one keep, one change, and one watch item. Deliver one concise cue and allow 3–5 attempts.

75–105 minutes — Retest. Record the same movement again. Compare the targeted behavior, not every metric. Ask the athlete whether the cue felt useful and natural.

Questions to answer

1. Which pattern repeated across multiple strides?

2. What changed with pace or fatigue?

3. What camera or landmark limitation matters most?

4. What single cue did you choose and why?

5. Did the retest improve the intended behavior without creating a new problem?

Generative AI knowledge check

Prompt 1: “Given this de-identified running-form summary, separate direct observations from interpretations. Suggest three context questions and one low-risk cue. Do not diagnose injury.”

Prompt 2: “Quiz me on how camera angle, speed, cadence, contact timing, hip drop, posture, and fatigue can change a running-form interpretation. Ask one question at a time.”

Prompt 3: “Critique this keep/change/watch feedback for clarity, autonomy support, false precision, and over-coaching. Rewrite it as a 30-second athlete conversation.”

Deliverable

Submit the de-identified before/after observations, one annotated still or report, the athlete response, and the next observation point.

APOPT Form Analysis: select the sport-specific workflow, standardize the camera view, and turn one observable pattern into one proportionate cue.
