CSCS Daily Practice Question #93

During an explosive jump, the quadriceps is briefly stretched as the legs extend to propel the body upward. Which proprioceptive response would immediately increase quadriceps activation?

A. Relaxation of the hamstrings to allow unobstructed knee extension

B. Activation of muscle spindles detecting stretch, triggering a reflex contraction of the quadriceps

C. Activation of Golgi tendon organs, which inhibits muscle contraction to prevent excessive tension

Answer in the poll, then explain your rationale below in the comments! I'll follow up with my breakdown of the question after enough people have responded.

From Chapter 1: Structure and Function of Body Systems
