简要总结
Open water swimming is a swimming discipline which takes place in outdoor water such as open oceans, lakes, and rivers. Elite swimmers are exposed to hypothermia when swimming in cold water, especially in long duration races, such as the 25-km race. The objective of this study is to evaluate the change in body core temperature in swimmers with continuous temperature monitoring during a 25-km race. The secondary objective is to identify the predictors of hypothermia and hypothermia-related drop-out.

结局指标
主要结局
Change in Water Temperature
时间窗: Continuous measurement was collected from 30 minutes before the race until 2 hours after the end of the race for each swimmer
Measurement of the Water Temperature using an electronic sensor (iButton® Maxim Integrated) which provide a continuous validated measurement
Change in Body Core Temperature
时间窗: Continuous measurement was collected from 30 minutes before the race until 2 hours after the end of the race for each swimmer
Measurement of Body Core Temperature using an ingestible electronic sensor (e-Celsius®, BodyCap , Caen, France) which provide a continuous validated measurement
次要结局
