During rapid eccentric contraction of the quadriceps, which consequence follows regarding the behavior of individual sarcomeres?

💡 Explanation

Eccentric contractions involve muscle lengthening while contracting, so sarcomeres can experience varied strain. Because sarcomeres aren't uniform in strength, some may undergo excessive stretch leading to sarcomere popping. Therefore, non-uniform lengthening increases 'popping' probability, rather than uniform stretch or increased actin-myosin affinity.
