Which statement best describes the difference between medial and lateral initiation in knee-focused plyometrics?

• A. Medial initiation inside the knee; lateral initiation outside the knee
• B. Medial initiation outside the knee; lateral initiation inside the knee
• C. Medial initiation inside knee; lateral initiation outside of knee
• D. Medial initiation at the ankle; lateral initiation at the hip

Answer: (C)

Medial versus lateral initiation describes where the knee's movement begins during the plyometric action. Medial initiation starts on the inside (toward the midline) of the knee, while lateral initiation starts on the outside (away from the midline) of the knee. This distinction is exactly captured by saying medial initiation inside the knee and lateral initiation outside of the knee. The other options either swap the sides or refer to initiation at joints unrelated to the knee (ankle or hip), which doesn’t describe knee-focused initiation.
