Infographic titled “ELASTICITY — FOUNDATION OF SPEED” defining elasticity as muscles, tendons and connective tissue storing and releasing energy in the stretch‑shortening cycle, with bullet points about quick rebound, a pre‑stretch effect enhancing speed and converting ground forces to propulsion, a graph showing speed rising as ground contact time shortens, a column of icons explaining why it matters (energy conservation, bounce factor, reduced ground contact <100ms, efficient transmission, tendon springs), and a triangle diagram labeling “BOUNCE = TRUE SPEED” supported by “ELASTICITY” and “POWER”.
