Which data category consists of measurements taken while the subject is in motion, including range and reach of movements?

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

Answer: (A)

Dynamic data describes measurements taken while the subject is in motion, capturing how the body moves over time and how far and in what directions it can reach during activities. This includes aspects like joint angles during movement, the path of a limb, and the speed or acceleration of actions, all of which reveal how movement affects fit and usability. That makes dynamic data the best fit for measurements that involve range and reach as people move, not just their static size. Anthropometrics are static measurements of body size and shape taken while stationary, clearance refers to the free space needed to avoid interference, and comfort is about the subjective feel of fit.
