Question

Predicting residual volume, rather than measuring it, likely increases the error in determining body density using hydrostatic weighing.

True or False

Answer 1

True, predicting residual volume instead of measuring it increases error in body density calculations during hydrostatic weighing, affecting body fat calculations.

Step-by-step explanation:

True. Predicting residual volume rather than measuring it does likely increase the error in determining body density using hydrostatic weighing. The accuracy of body density calculations depends on precise measurements of both weight in air and submerged weight. Since residual volume could vary significantly between individuals, an estimated value could introduce errors into the calculation. These errors can affect the resultant percent body fat calculation, which is critical in fields such as medical diagnostics and athletic training.
