Can the continuous exercise improvement the children's temperature at immediately after getting up?

研究人员对加入高级班的幼儿园儿童全天的鼓室温度变化进行了调查。志愿者的孩子根据起床后的体温值进行分类；体温低于平均值减去1个标准差的患儿为“低温组”，其余患儿为“对照组”。温度较低组起床后、晚餐前和睡觉前的温度都低于对照组。低温组低负荷运动时的心电图高频分量较低，推测心脏副交感神经的能力较低。

The change in tympanic temperature was investigated throughout a day for kindergarteners who joined senior class. The volunteer's children were classified by the value of one's temperature at immediately after getting up; the child who's temperature was lower than 1 standard deviation subtracted from the mean value belonged to "Lower temperature group" and other child belonged to "Control group". The Lower temperature group was indicated that temperatures immediately after getting up, before dinner and before going to bed were lower than the Control group. And, the high frequency component of electrocardiogram during low-loaded exercise was lower in the Lower temperature group, therefore it can be speculated that the ability of cardiac parasympathetic nerve was low.
