A normal BIA range refers to the healthy percentages of body composition components, most commonly body fat, as estimated by Bioelectrical Impedance Analysis. These ranges typically vary significantly based on an individual's age and sex.
Understanding Bioelectrical Impedance Analysis (BIA)
Bioelectrical Impedance Analysis (BIA) is a quick and non-invasive method used to estimate body composition, including body fat percentage, muscle mass, and body water. The technique works by sending a low-level electrical current through the body and measuring the resistance it encounters. Since fat tissue contains less water than muscle tissue, it offers more resistance to the electrical current, allowing BIA devices to calculate an estimated body fat percentage [1].
Normal Body Fat Percentage Ranges for Women (BIA)
Based on the provided reference for "Fat tissue", the normal body fat percentage ranges measured by BIA are categorized by age group. It is important to note that the specific data provided in the reference primarily details ranges for women.
The normal body fat percentage ranges for women, according to the reference, are as follows:
| Age Group | Normal Body Fat Percentage (Women) |
|---|---|
| 15 to 24 | 23 to 29.6% |
| 25 to 34 | 22.9 to 29.7% |
| 35 to 44 | 22.8 to 29.8% |
While the provided reference includes columns for "Men" and "Women" in its header, the detailed ranges provided in the specific snippet (e.g., "23 to 29.6%") correspond to the normal body fat percentage for women across the respective age groups.
