During which healing stage are plyometric exercises generally introduced?

• A. Acute stage
• B. Subacute stage
• C. Chronic stage
• D. Pre-injury stage

Answer: (C)

Plyometric training relies on the stretch-shortening cycle and places high demands on tissue, strength, and neuromuscular control. It is introduced when the healing tissue has progressed enough to tolerate rapid, high-load movements. In the acute stage, inflammation and pain limit movement and loading, making jumping and explosive work risky. In the subacute stage, healing continues but tissues may still be sensitive and ramping up to high-load tasks too soon can provoke re-injury. By the chronic stage, inflammation has resolved, strength and function have been restored, and the athlete can safely handle the demands of plyometrics to rebuild power and sport-specific performance. Pre-injury stage isn’t a healing phase.
