Plyometric exercises are most appropriately incorporated into which healing stage?

• A. Acute stage
• B. Subacute stage
• C. Chronic stage
• D. Return-to-sport stage

Answer: (C)

Plyometric training relies on tissue tolerance and neuromuscular readiness to handle high-load, fast movements that stress the tendon and muscle through the stretch-shortening cycle. In the acute phase, inflammation and tissue fragility make high-impact loads risky, so protection and gentle loading are emphasized. In the subacute phase, you continue to progress loading but the tissue may still be sensitive, so explosive plyometrics are usually avoided or very carefully dosed. By the chronic stage, the healing tissue has undergone remodeling and gained strength and resilience, allowing higher-load, coordinated movements to be introduced. This stage provides the best window to rebuild power, tendon stiffness, and motor control with controlled plyometric drills, while keeping risk-managed progression. While plyometrics may appear later in return-to-sport planning, they are most appropriately incorporated once the tissue can tolerate substantial loading, which aligns with the chronic stage.
