Seven experiments were performed to examine the heat and cold responses of young women in relation to physical training and/or the menstrual cycle. (1) The results of the 1st experiment using the foot bath method suggest that in young women physical training improves sweating and vasodilation functions, and affecting both central and peripheral mechanisms in the sweating function and the central rather than peripheral mechanism in the vasodilation function. The improvement of the central mechanism in both functions by physical training was more marked in the mid-luteal than the mid-follicular phase (due to the marked group difference of the female hormones in the luteal phase). (2) The results of the 2nd experiment suggest that physical training improves cutaneous vasodilation both centrally and peripherally during exercise as well as at rest mentioned above (the 1st experiment). (3) The results of the 3rd experiment indicate that the superior cutaneous vasodilation observed in the phy … More sically trained women (compared to untrained women) may be due to a greater withdrawal of vasoconstrictor tone, but not due to a greater active vasodilation. (4) The results of the 4th experiment showed that arterial blood is preferentially redistributed to active muscle and skin rather than inactive muscle in only untrained women exercising at 65%VO2max, and suggested that such redistribution occurs at higher intensity of exercise in trained women. (5) The results of the 5th experiment suggest that, compared to men, women depend on insulation by thicker subcutaneous fat rather than by greater cutaneous vasoconstriction during a mild cold stress. The central mechanism contributing to vasoconstriction is modified by the menstrual cycle, while the peripheral mechanism is affected by sex and menstrual cycle. (6) The results of the 6th experiment suggest that women complaining of unusual coldness suffer a deterioration of cutaneous vasodilation during a rise of environmental temperature after cold stimulus. The deterioration was more marked on upper limbs. (7) The results of the 7th experiment indicate that the cold-induced vasodilation is inferior in women rather than men, and particularly so in women complaining of unusual coldness. Less

进行了七个实验，以检查热和冷的反应，年轻女性的体育锻炼和/或月经周期。(1)第一次实验结果表明，在年轻女性中，体育锻炼改善了出汗和血管舒张功能，并影响中枢和外周机制的出汗功能和中枢而不是外周机制的血管舒张功能。通过体育锻炼对这两种功能的中枢机制的改善在黄体中期比在卵泡中期更显著（由于黄体期雌性激素的显著组间差异）。(2)第2实验的结果表明，体育锻炼改善了上述运动期间和休息时的中枢和外周皮肤血管舒张（第1实验）。(3)第3次实验的结果表明，在PHY中观察到的上级皮肤血管舒张 ...更多信息 生理训练的女性（与未训练的女性相比）可能是由于血管收缩张力的更大撤回，但不是由于更大的主动血管舒张。(4)实验4的结果表明，在65%VO2max运动时，只有未经训练的女性的动脉血优先重新分配到活动肌肉和皮肤，而不是非活动肌肉，并表明这种重新分配发生在受过训练的女性的高强度运动中。(5)第五个实验的结果表明，与男性相比，女性在轻微的冷应激期间依赖于更厚的皮下脂肪而不是更大的皮肤血管收缩的绝缘。导致血管收缩的中枢机制受月经周期的影响，而外周机制受性别和月经周期的影响。(6)第6个实验的结果表明，在寒冷刺激后环境温度升高期间，抱怨异常寒冷的女性皮肤血管舒张恶化。上肢的恶化更为明显。(7)第7次实验的结果表明，女性的冷诱导血管舒张比男性差，特别是在抱怨异常寒冷的女性中。少
