According to the National Fire Agency, 69% of South Korean firefighters prefer the three circuit system. Since the three circuit system involves working for 24 h consecutively, it could reduce work performance of firefighters and their participation in exercise training (ET) and fitness levels could be affected by shift type. The present study examined the impact of shift type on ET and identified the interaction effect between shift type and city size on ET among South Korean firefighters.
A series of logistic regression models were used to analyze the data collected from incumbent outside workers among Korean firefighters (N = 5196) in 2017.
Firefighters under the 3 circuit system participated in ET less frequently than did those under the 21 circuit system, and the difference was greater in large cities than in small towns. This could be because of the greater opportunity to participate in leisure activities in large cities, or because participating in ET is easier for firefighters in small towns, who tend to be less busy than those in large cities.
The three circuit system is not feasible in the present situation in South Korea. Therefore, an environment suitable for the three circuit system should be established.
据韩国国家消防局称，69%的消防员更喜欢三班次制。由于三班次制需要连续工作 24 小时，这可能会降低消防员的工作绩效，他们参加体能训练（ET）的情况和体能水平可能会因班次类型而受到影响。本研究调查了班次类型对 ET 的影响，并确定了班次类型与城市规模之间的交互效应对韩国消防员 ET 的影响。
使用一系列逻辑回归模型分析了 2017 年韩国在职外勤消防员（N=5196）的数据。
与 21 班次制相比，三班次制的消防员参与 ET 的频率较低，而且在大城市的差异更大。这可能是因为在大城市有更多的机会参加休闲活动，或者因为在小城市消防员的工作压力较小，所以参与 ET 更容易。
在韩国目前的情况下，三班次制不可行。因此，应建立适合三班次制的环境。
