Self-Myofascial Release (SMR)

  • Purpose: Releases tension in overactive muscles, enhancing overall flexibility.
  • Technique: Sustain pressure on tender spots for at least 30 seconds to relieve adhesions.

Flexibility Training Phases (OPT Model)

  • Corrective Flexibility: Uses self-myofascial release and static stretching to address imbalances.
  • Active Flexibility: Incorporates self-myofascial release and active-isolated stretching.
  • Functional Flexibility: Involves self-myofascial release combined with dynamic stretching.

Flexibility Assessment and Application

  • Perform flexibility techniques on tissues identified as overactive in assessments.

Practical Stretching Procedures

  • Follow specific actions for the gastrocnemius, TFL/IT band, adductors, latissimus dorsi, and pectorals to ensure effective muscle elongation.
  • Maintain core engagement and optimal posture during stretches to maximize benefits.

Acute Variables for Stretching
