Human body measurements taken when the subject is in motion related to range and reach of various body movements. E.g. crawling height, overhead reach and the range of upper body movements.

• A. Anthropometrics
• B. Dynamic data
• C. Clearance
• D. Comfort

Answer: (B)

Dynamic data describes measurements taken while a person is moving to capture how far and how high they can reach, including movements like crawling, overhead reach, and the range of upper-body motion. This kind of data reflects functional movement and how the body actually utilizes space during activity, which is essential for designing environments and products that accommodate real use. In contrast, static anthropometrics focuses on fixed body dimensions measured in still postures, so it wouldn’t capture how reach and clearance change with movement. Clearance refers to the amount of space needed to avoid contact with obstacles, not to measuring movement range itself, and comfort is about subjective feel rather than objective motion-based measurements.
