Which option is a physiological instrument used in adapted physical activity research?

• A. Force plates
• B. Motion capture cameras
• C. Body composition measurements
• D. Administrative surveys

Answer: (C)

Understanding physiological instruments means focusing on tools that quantify the body's internal characteristics. Body composition measurements provide data on fat, lean mass, and bone—physiological properties that reflect health and functional status and inform how an adapted physical activity program affects the body. This makes them a direct physiological instrument in research. In contrast, force plates and motion capture cameras are mainly biomechanical tools that track movement and forces, not the body's internal state, while administrative surveys collect subjective or administrative information rather than physiological data.
