Applied Anatomy and Physiology

Flashcards focusing on the mechanics of the stretch-shortening cycle (SSC) and its applications in sports and physical training.

What is the stretch-shortening cycle (SSC)?

A neuromuscular phenomenon involving an eccentric contraction followed by a rapid concentric contraction, enhancing force production and efficiency.

What are the three primary components of the stretch-shortening cycle?

Eccentric phase, amortization phase, and concentric phase.

What occurs during the eccentric phase of the SSC?

The muscle lengthens while storing elastic energy.

What is the amortization phase in the SSC?

A brief period between eccentric and concentric contractions.

What happens during the concentric phase of the SSC?

A rapid release of stored elastic energy, leading to enhanced force output.

What training method is particularly effective for enhancing SSC performance?

Plyometric training, which involves quick, explosive movements.

Why is understanding the SSC important for athletes?

It enhances performance and aids in developing effective training protocols.

How can eccentric training improve the SSC?

By enhancing the muscle’s ability to generate and utilize stored elastic energy.

What are some techniques that can target the SSC?

Drop jumps and depth jumps.

What are some benefits of effectively utilizing the SSC in athletes?

Enhanced performance in explosive power activities and improved injury prevention strategies.
