本研究的目的是检查直肠温度（T（re））在不同深度的差异。19名年轻男性进行了两轮自行车运动和恢复。在4、6、8、10、13、16和19 cm深度处同时测量T（re），同时测量皮肤温度。我们发现，在绝对T（re），T（re）的上升幅度和T（re）的反应滞后的深度小，但统计学显着差异。在运动前稳定阶段，4cm深度的T（re）比16 cm深度的T（re）低0.5A ℃（p < 0.05）。由于在直肠中测量的深度较浅，运动期间T（re）的上升幅度较大。然而，10、13、16和19 cm处的T（re）升高显示无全身差异。在7个深度中，16 cm深度的T（re）特征最稳定，潜伏期最长（3.1 +/- A 1.3 min）和最小上升（0.8 +/- A 0.3A摄氏度），而4cm深度的T（re）对运动和休息的变化反应最快，潜伏期最短（1.0 +/- A 0.6 min）和最大温升（1.2 +/- A 0.5A ℃）。从4到19厘米的深度观察到的差异在一定程度上被运动抵消。综上所述，在重复运动和休息期间，T（re）以不同的方式出现，根据七个深度，但T（re）超过10 cm深度似乎没有系统性差异。
The purpose of the present study was to examine the discrepancies in rectal temperature (T (re)) at various depths. Nineteen young males performed two bouts of bicycle exercise and recovery. T (re) was simultaneously measured at depth of 4, 6, 8, 10, 13, 16, and 19 cm, alongside the measurement of skin temperatures. We found small but statistically significant differences by depth in the absolute T (re), the magnitude of rise in T (re) and the lag of response in T (re). During the stabilization stage before exercise, T (re) at 4 cm-depth was 0.5A degrees C lower than T (re) at 16 cm-depth (p < 0.05). As the depth measured in the rectum was shallower, the rise in T (re) during exercise was greater. However the rise in T (re) at 10, 13, 16 and 19 cm showed no systemic difference. Among seven depths, T (re) at 16 cm-depth had the most stable feature with the longest latent period (3.1 +/- A 1.3 min) and the smallest rise (0.8 +/- A 0.3A degrees C), while T (re) at 4 cm-depth was the most responsive to the change of exercise and rest with the shortest latent period (1.0 +/- A 0.6 min) and the greatest rise (1.2 +/- A 0.5A degrees C). The differences observed in the depths from 4 to 19 cm were offset by exercise to some extent. In summary, T (re) appeared in different manners according to the seven depths during the repetition of exercise and rest, but T (re) deeper than 10 cm-depth seemed to have no systematic differences.
