我国北方冬泳运动员经常接触的冷水环境,为一般人日常生活中绝难经历的严酷冷应激条件。在手指浸泡冰水的试验中,冬泳者指温高、血管舒张反应比对照组较早出现。尽管其在冷中有较强的保持肢端温度的能力,但4h的全身冷暴露过程中,其体心温度及股皮温却低于对照组,较少发生寒战,痛感轻,代谢率也不似对照组那样地明显增强。表明冬泳者属于低体温——隔热型的冷适应。 The cold water environment in which the northern winter swimmers in our country are constantly exposed is the severe cold stress condition experienced by ordinary people in their everyday life. In the finger soaked in ice water test, the winter swimmer refers to the warm high, vasodilatation response appeared earlier than the control group. Despite its ability to maintain acral temperature in the cold, 4h of body cold exposure, body temperature and the skin temperature was lower than the control group, less chills, pain, light weight, metabolic rate Unlike the control group as significantly enhanced. Show that the winter swimmer is a low temperature - insulation type of cold adaptation.
