Stretch-Shortening Cycle (SSC)

The rapid stretch and contraction sequence that enhances force production.

The stretch-shortening cycle (SSC) occurs when a muscle is rapidly stretched (eccentric) before immediately contracting (concentric). This sequence stores elastic energy during the stretch and potentiates the subsequent contraction, producing more force than concentric-only action. The SSC is fundamental to jumping, running, and throwing.

Examples

  • Counter-movement before jumping
  • Arm swing before throwing
  • Bounce at bottom of squat (not recommended)
