Following a resistance exercise protocol post-rotator cuff repair with predetermined phases is a form of _____.

• A. Periodization
• B. Isotonic training
• C. Randomization
• D. Reversibility

Answer: (A)

Periodization in rehabilitation is the idea of planned, progressive phases with specific goals, loads, and activities designed to guide recovery and adaptation over time. In a post-rotator cuff repair protocol, using predetermined phases (such as protections, ROM restoration, gradual strengthening, and functional progression) creates a structured plan that aligns with tissue healing and functional milestones. This organized pacing helps protect the repair early on while gradually increasing demand, which is exactly what periodization aims to achieve.

Isotonic training describes a type of muscle contraction with a variable resistance—it's not about how the program is organized over time. Randomization involves assigning subjects or tasks by chance, which isn’t relevant here. Reversibility refers to the loss of training gains after stopping exercise, not the systematic progression through phases.
