PWR-015 · Power, Speed & Agility

Change of direction

Change of direction is real as a bounded, measurable capability, but the evidence is task- and population-specific. Titan separates improvement in the test from retention, transfer and meaningful function.

Explanation is not permission.

This dossier explains the evidence and its limits. It is not a diagnosis, personal recommendation, assessment, clearance, performance promise or training programme. Actionable teaching appears only when the canonical Power record explicitly authorises it.

Complete bounded explanation

What this power means.

Capability to develop or express change of direction in a declared context without inheriting broader claims.

What the current evidence supports

In selected people and declared configurations, change of direction can be measured and may improve with task-relevant practice; retention, transfer and meaningful value require separate testing.

How to observe or measure it without overclaiming

Declare course, angle, entry speed and timing method; separate total time, COD deficit and reactive decision latency.

Myth

Impossible agility

Metric

Pre-planned COD completion and COD deficit at a fixed approach speed, with reactive agility tested separately

Boundary

The metric is valid only for its declared task and cannot establish universal ability, character, diagnosis, safety or far transfer.

Negative and limiting findings

  • Agility training did not improve straight sprint performance in the Young study.
  • Pre-planned COD gains do not establish decision-making or opponent-responsive agility.

Claims this evidence cannot support

  • Titan proves anyone can develop unlimited or superhuman change of direction.
  • One test score reveals whole-person capability, health, discipline, potential or worth.
  • Improvement guarantees injury prevention, clinical benefit, occupational readiness or transfer to every real-world task.

How to learn this Power now.

The learner completes three valid pre-planned 45-degree cuts from the same approach side and speed band, with course time, straight-sprint comparison and technique recorded.

  1. Get readyWalk the course in both travel directions and check that no cone creates a trip point.
  2. Learn the method7 concrete steps teach the permitted method from start to finish.
  3. See right and wrong5 comparisons show correct or safer execution beside common wrong or riskier choices.
  4. PractiseThe provider controls angles, sides, approach speed, trials, rest and later reactive cues. Progress angle or speed one at a time; unplanned agility remains a separate advanced assessment.
  5. Check progressUse the same course, entry-speed band, surface, footwear and timing; record route faults, plant alignment and a matched straight sprint.

Authority boundary: Titan teaches the complete method; a qualified person controls the parts that require supervision, clearance, specialist equipment, load, dose or progression. The method is Power-specific; its actionability follows this treatment.

Current teaching and evidence boundary

The next gate remains visible.

External confirmation is required before higher-authority use because: a clinical, high-risk or regulated configuration; a supervision or non-attempt boundary.

A Power-specific tutorial is available at /tutorials/pwr-015/. It contains a plain-English method, 7 ordered steps, a worked example, right-versus-wrong comparisons, specific mistakes and corrections, practice, measurement, accessibility, stopping rules and evidence. Its supervised mode remains controlling.
