contraction relax definition
Contract relax: isotonic contraction of the antagonist followed by passive stretch. Hold-relax: isometric contraction of the agonist followed by passive stretch. Agonist contract-relax: body part is moved actively in the agonist pattern via isotonic contraction of the agonist (active stretch).Slow reversal-hold-relax: isotonic contraction of the antagonist followed by an isometric contraction of the agonist followed by a relaxation phase.ontract relax: isotonic contraction of the antagonist followed by passive stretch. Hold-relax: isometric contraction of the agonist followed by passive stretch. Agonist contract-relax: body part is moved actively in the agonist pattern via isotonic contraction of the agonist (active stretch).
