Changes in the temperature, area, and heat energy output of the regions of interest in the left and right cervical–supraclavicular regions in the low-BAT and high-BAT groups during cold challenge
| Variables | Low-BAT group | High-BAT group |
|---|---|---|
| ΔTemperature (°C) | ||
| Left | 0.41 (±0.04) | 0.28 (±0.10) |
| Right | 0.43 (±0.04) | 0.34 (±0.10) |
| ΔArea (cm2) | ||
| Left | 6.29 (±1.68) | 11.92 (±1.68)* |
| Right | 6.24 (±1.41) | 13.31 (±5.11) |
| ΔHeat energy output (W) | ||
| Left | 0.33 (±0.09) | 0.61 (±0.08)* |
| Right | 0.32 (±0.07) | 0.68 (±0.26) |
| ΔTotal heat energy output (W) | ||
| – | 0.65 (±0.13) | 1.28 (±0.26)* |
* Significant difference at p < 0.05 (Student’s t test) between low-BAT and high-BAT groups
Values are presented as the mean (±SE). Total heat energy output is the sum of the heat energy output from left and right regions of interest (ROIs), calculated based on the Stefan–Boltzmann law. The paired t test showed no significant differences between the left and right ROIs
