Enter derived force-plate metrics from the athlete's testing system (ForceDecks, Hawkin Dynamics, VALD, Sparta, etc.). Use median of 3 trials unless your organization standardizes best trial or mean.

Right/Left fields are optional. Leave blank if dual force-plate data is unavailable — bilateral metrics above will still drive scoring.

Drop Jump

DJ — Reactive Strength Metric Entry

If RSI is left blank, it is calculated as RSI = (jump height m) / (contact time s) using the median jump height and median contact time.

Concentric Asymmetry

Meaning Side-to-side difference in propulsive force generation strategy.

Implication Unilateral strength & power development, limb confidence, sprint-acceleration symmetry, single-leg jump training emphasis.

Eccentric Asymmetry

Meaning Side-to-side difference in braking and force-absorption capacity.

Implication Landing mechanics, deceleration efficiency, cutting strategy, ACL / Achilles / groin injury considerations.

Landing Force Asymmetry

Meaning Asymmetric load-acceptance strategy at ground contact.

Implication Altered landing mechanics, offloading from the involved limb, and potential return-to-sport progression concern.

Court Translation

Basketball Application

Peak Force Concentric Impulse Concentric RFD

Low values may indicate limited ability to create early propulsion — first-step quickness, drives, and transition acceleration may be compromised.

Eccentric Impulse Braking RFD Deceleration Time Peak Landing Force

Poor braking profile may limit closeouts, defensive stops, cuts, and progression toward open-court return-to-play.

Eccentric Asymmetry Braking RFD Asymmetry RSI Landing Asymmetry

Asymmetric or slow braking strategy may reduce cutting efficiency and produce compensatory off-leg loading.

Peak Landing Force Landing Asymmetry Braking Time

High landing forces with poor braking control may indicate poor load acceptance during rebound contests and post-jump landings.

RSI Ground Contact Time CMJ Jump Height Impulse

Low RSI or prolonged contact time may suggest poor elastic / reactive qualities, with implications for repeat sprints, transition play, and late-game performance retention.

Evidence Anchors

CMJ Force-Plate Reliability & Interpretation Reliability and minimal detectable change for CMJ force-time variables across vendors (ForceDecks, Hawkin Dynamics, VALD, Sparta). Use system-specific reference ranges where available.

Force-Time Metrics & Impulse Concentric and eccentric impulse, RFD, and time-based metrics as drivers of jump and sprint performance. Impulse-momentum relationship as the foundation of jump output.

RSI & Drop Jump Performance Reactive Strength Index as an index of fast stretch-shortening cycle quality; drop height optimization, contact-time targets, and population-specific norms.

Inter-Limb Asymmetry in Sport Magnitude, direction, and task-specificity of asymmetry. Functional vs artefactual asymmetry; thresholds for monitoring vs intervention; longitudinal stability.

Deceleration & Change-of-Direction Eccentric strength, braking impulse, and horizontal deceleration as determinants of cutting efficiency, COD performance, and lower-limb injury risk.

Basketball-Specific Force-Plate Application Position-specific norms, in-season monitoring, return-to-play criteria, and translation of laboratory force-time metrics to court actions (drives, closeouts, rebounding).
