FAMILY 02: POWER, SPEED & AGILITY
Superdomain: Body & Performance. This family contains eight stable Power records.
PWR-009 · Acceleration
Evidence route: Externally gated evidence dossier. Use the linked canonical tutorial for current teaching, accessibility, safety and editorial-review status; this evidence dossier does not enlarge that tutorial’s authority.
Summary. Acceleration 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.
Definition. Capability to develop or express acceleration in a declared context without inheriting broader claims.
What the current evidence supports. In selected people and declared configurations, acceleration can be measured and may improve with task-relevant practice; retention, transfer and meaningful value require separate testing.
Measurement boundary. Use instrumented split times or velocity-time data with surface, footwear, start and aid declared; do not infer reaction ability, agility or safety from a 10-m time.
Myth. Instant zero-to-maximum speed
Metric. Velocity change and split time over a predeclared distance with start method and environment fixed
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.
Moderate resisted conditioning sprints gave no acute potentiation advantage in varsity sprinters.
Resisted training that improved acceleration did not necessarily improve maximum-speed phase or jump more than comparison training.
Claims this evidence cannot support.
Titan proves anyone can develop unlimited or superhuman acceleration.
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.
