The purpose of this study is to examine the effect of firefighters’ shift-type and exercise training environment on participation of firefighters in exercise training. Based on arguments of many previous studies that shift work has adverse effects on health, this study examined whether there is any difference in the participation of firefighters’ voluntary exercise training according to their shift-type. The shift-type of firefighters is basically operated in 3 team 2-shift system in the form of 6, 9, and 21 circuit. However, this work pattern seems overloaded, so the need for operation of
“on-off-off (3 cycles)” circuit, which is having 48 hours break after 24 hours work, has been suggested. Based on this background, this study examined whether there is any difference in the effect of the
“on-off-off” circuit system and the current shift-type on the participation of firefighters in exercise training. The shift-type of firefighters is operated differently in each fire station depending on the number of firefighting mobilization. Because individual firefighters
are nested in the firefighting organization, we carried out a multi-level analysis in this study. For the analysis, we divided 224 regions in municipal, county, and district unit across the country into large cities and small cities and set them as group level variables. In addition, this study set the number of firefighting mobilization as another group level variable considering the fact that the shift-type is different depending on the number of mobilization. In accordance with these variables, this study examined the effect of city size and the number of firefighting mobilization on the participation of firefighters in exercise training. Moreover, this study analyzed the cross-level interaction effect to examine if the participation of firefighters in exercise training varies according to each shift-type when the city size and the number of firefighting mobilization are controlled.
For exercise training environment factors, this study examined if the size of exercise training facilities is appropriate, if there is any peer workers who can instruct exercise training, and if the exercise training is available during work and analyzed if those three exercise training environment factors affect the participation of firefighters in exercise training.
For this analysis, this study used the secondary data of the online anonymous questionnaire survey, “A study for establishment of activity system of firefighters and for securing their work continuity”, conducted by the Ministry of Public Safety and Security in 2017 and the number of firefighting mobilization obtained through information disclosure request. Since the number of 21 and 9 circuits was relatively higher than that of other work circuit in 2017, this study compared the effect of the 21 circuit, 9 circuit, and “On-off-off”
circuit on the participation of the firefighters in the exercise training.
As a result, it was found that both 9 circuit and 21 circuit firefighters participate more in exercise training than “On-off-off”
circuit firefighters, which was statistically significant. In terms of city
size, firefighters in small cities participate more in exercise training than firefighters in large cities, whereas the effect of the number of firefighting mobilization on the participation of firefighters in exercise training was not statistically significant. As a result of cross-level interaction effect, the 9 circuit and 21 circuit firefighters participated more in exercise training when working in large cities, and the
“On-off-off”circuit firefighters participated more in exercise training when working in small cities. On the other hand, there was no statistically significant difference in the effect of the number of firefighting mobilization in each group on the participation in exercise training according to shift-type. In other words, the number of firefighting mobilization in each group did not explain the effect of city size on the participation in exercise training. In terms of the exercise training environment, the firefighters who answered that there was a peer worker who could guide their exercise training as well as that they were able to do exercise training during work participated more in exercise training than those who did not. On the contrary, the firefighters who answered that the scale of their exercise training facilities were appropriate participated less in exercise training than those who did not.
This study is meaningful in that it found out the factors influencing exercise training participation of firefighters who are required to have high level of physical strength. Based on the results of this study, future research should better propose a policy alternative to improve the participation of firefighters in exercise training.
