Final answer:
To determine body composition with bioelectrical impedance, you need to know the individual's height, age, weight, and gender, as these parameters affect the flow of electrical current used by Bioelectric Impedance Analysis (BIA) to assess body composition.
Step-by-step explanation:
In order to determine body composition with bioelectrical impedance, you must also know the individual's height, age, weight, and gender. These parameters are essential as they influence the electrical current's path through the body, which is fundamental to accurately determining body composition using Bioelectric Impedance Analysis (BIA). For example, taller individuals may have a different body composition reading compared to shorter individuals even if they have the same weight due to the longer path electricity must travel. Similarly, age and gender can affect body composition, as they are associated with different body fat distribution and muscle mass. Therefore, for accurate measurements, height, age, weight, and gender should all be accounted for.
