Abstract
Wildland firefighters' (WF) routine involves long displacements and intense physical demands, interspersed with sedentary behavior (SB). Little is known about SB and daily steps pattern of WF during routine work. PURPOSE: We analyzed the SB and total daily steps of Brazilian WF during a 24-hour shift-work. METHODS: We evaluated 22 WF, aged 35.9±6.4 yrs, BMI of 25.3±2.9 kg/m2, during the dry season. Volunteers wore an accelerometer (ActiGraph-GT3X+) during a 24h shift work and reported main duties performed on a log. SB was evaluated by the vector magnitude using <200 counts/min as cut-off point. We compared SB and daily steps according to 3 periods of the day: morning (08:00-11:59 plus 06:00-07:59 of the following day); afternoon (12:00-17:59) and evening (18:00-23:59). Night period (00:00 to 05:59) was excluded due to insufficient data. We compared SB and daily steps during the day and between those who participated or not in at least one episode of wildland fire suppression (Mann-Whitney text). Friedman text with a Wilcoxon post-hoc test (p-value ≤0,02) were used to compare the 3 moments. Data are shown as median (min-max). RESULTS: WF spent 73 (15-142) min in the morning, 131 (17-192) min in the afternoon and 109 (13-193) min in the evening on SB. They accumulated 3,508 (1,322-12,237) steps in the morning, 4,105 (963-18,450) in the afternoon and 5,499 (571-13,883) in the evening. Those who participated or not in at least one episode of wildland fire suppression showed similar SB and daily steps (p>0,05). SB pattern throughout the day are show on Figure 1. CONCLUSION: WF achieved similar daily steps in the 3 periods of the day. Time spent in SB was higher in the evening as compared to the morning. Our results suggest that WF remain little time in SB as compared to other professions and achieved a high daily steps count (>10,000) during a 24-h routine work.Figure 1.: Sedentary behavior by different moment on day among on-duty firefighters Friedman text (p= 0.03); *Wilcoxon text (p= 0.01)
