Unformatted text preview: – this is modeled as a spring in series with the tendon. All tension exerted by the muscle on the bones must pass through the SEC. Whenever the muscle develops tension, the SEC stretches. The SEC shortens during relaxation. The SEC also stretches when the muscle is stretched which also increases the tension. 2. Parallel Elastic Component (PEC) – this is modeled as a spring buried in the body of the muscle from tendon to tendon. As the muscle contracts, it compresses this spring.
