Ankle & Knee Elasticity · Reacting to an auditory whistle trigger — PREPARATIONMark a flat non-slip lane; start without obstacles. Position lights as readable cues; never force a collision-prone sprint.1PREPARATIONMark a flat non-slip lane; start withoutobstacles.

Perform short low-amplitude ankle pulses with full balance. Add a single controlled lateral displacement and stable stop. Start only after the signal, but retain visual ball tracking and a safe stopping distance.2EXECUTIONRehearse quiet two-foot landing with kneesfollowing toes.

COACH EXECUTION CARD

Practical on-court execution

Starting coaching cues to adapt for player level, squad size and readiness.

01 · Purpose

Technical / tactical target

Prepare lower-leg spring and knee tracking for short contacts.

02 · Setup

Court and equipment

Mark a flat non-slip lane; start without obstacles.

Position lights as readable cues; never force a collision-prone sprint.

03 · Execution

Progressive steps

  1. Rehearse quiet two-foot landing with knees following toes.
  2. Perform short low-amplitude ankle pulses with full balance.
  3. Add a single controlled lateral displacement and stable stop.
04 · Applied progression

Reacting to an auditory whistle trigger

Start only after the signal, but retain visual ball tracking and a safe stopping distance.

No separately verified photograph exists for this constraint. See the parent setup reference image.

Suggested dose

2–3 sets × 6–8 contacts with recovery.

Success criterion

Ankles absorb, knees do not collapse inward.

Safety and adaptation

Skip impact progressions when soreness or pain is present.
