Question

Which of the following are phases of the stretch-shortening cycle?

1) amortisation
2) eccentric
3) isometric
4) concentric

Answer 1

The phases of the stretch-shortening cycle include amortisation, eccentric, and concentric.

Step-by-step explanation:

In the stretch-shortening cycle, the following phases are involved:

• Amortisation: This phase is also known as the transition phase, where the muscle changes from eccentric to concentric contraction. It is the shortest phase and involves a brief pause between the eccentric and concentric contractions.
• Eccentric: This phase occurs when the muscle lengthens while contracting. It is characterized by the tension in the muscle diminishing.
• Concentric: This phase involves the muscle shortening while contracting. It generates tension and allows movement.
