Characteristics of firefighters in control (CON) and sleep restriction (SR) conditions
| Characteristic | CON (n = 18) | SR (n = 17) |
|---|---|---|
| Age (years) | 39 ± 16 | 39 ± 15 |
| Men:Women | 15:3 | 15:2 |
| Weight (kg) | 84.9 ± 17.8 | 93.8 ± 20.2 |
| Height (cm) | 178.1 ± 7.7 | 177.8 ± 7.4 |
| BMI (kg/m2) | 26.8 ± 5.0 | 29.6 ± 5.5 |
| Firefighting experience (years) | 6 (min–max 1.0–39.0) | 10 (min–max 1.0–20.0) |
| Presimulation (16 h) physical activity (total activity counts) | 305,233 ± 34,369 | 256,726 ± 19,609 |
BMI, body mass index; age, weight, height, and BMI are presented as mean ± standard deviation; firefighting experience is presented as median years and minimum–maximum years; For ease of interpretation, presimulation log physical activity data were back-transformed to total activity counts.
