【摘要】：以往的人体全身出汗率的测定方法在实际操作中存在各种困难,本文提出了一种新的测定人体全身出汗量的方法——衣物增重法,并利用该法分别测定20。C、25℃和28℃3种环境温度下,8名受试者在跑步机上分别以0.90m/s(2mi/h)、1.78m/s (4mi/h)和2.68m/s(6mi/h)的速度跑步15min后的全身出汗率。然后运用配对t检验对8名受试者单位面积出汗率结果进行分析后发现,环境温度和活动强度对人体单位面积出汗率均有显著影响,环境温度分别为20℃、25℃和28℃以及活动强度分别为0.90m/s、1.78m/s和2.68m/s时,人体单位面积出汗率的范围为1.605～681.100 g/(h·m2),同时也论证了衣物增重法是测定人体全身出汗率的一种有效方法。在测定全身出汗率的同时还监测了受试者10个心肺功能指标,通过皮尔逊相关分析后得出,呼吸交换率、02等价通气量、C02等价通气量均与全身单位面积出汗率不相关,其他7个生理指标均分别与单位面积出汗率显著正相关,其相关程度的高低排序为：摄氧量每分钟通气量C02呼出量相对摄氧量代谢当量潮气量呼吸频率。这表明,通过监测心肺功能指标可大致描述人体综合受热程度以及活动强度,同时得到单位面积出汗率的预测。此外,本文还利用滤纸片法分别测定20℃、25℃和28℃3种环境温度下,1名男性受试者在跑步机上分别以0.90m/s、1.78m/s和2.68m/s的速度跑步15min后其上身10个部位的局部出汗率。通过配对t检验得出,置信度为90%时,按单位面积出汗率的大小和差异显著性可将上身10个部位分成4组,其排序为：腹部上部背部左下部和背部左中部胸部、肩胛骨和腹部肩部、上臂处、脊柱上部和脊柱中部。除20℃、0.90m/s与20℃、1.78m/s时该名受试者上身局部单位面积出汗率没有显著差异外,其他配对t检验的结果都表明环境温度和活动强度对上身局部单位面积出汗率均有显著影响,环境温度分别为20℃、25℃和28℃以及活动强度分别为0.90m/s、1.78m/s和2.68m/s时,该名受试者上身10个部位的单位面积出汗率的范围为2.0～1418.4g/(h·m2)。人体全身及上身各部位出汗率的测定为研究出汗状态下的服装热湿舒适性提供了基础生理学数据、为探讨出汗调节机制提供了线索以及完善了人们对上身部位的出汗差异认识,能为运动服装的结构设计、面料选择以及出汗假人的设计提供参考依据。
[Abstract]:Method for the determination of human body sweating rate of previous difficulties in the actual operation, this paper presents a method of clothing weight method for the determination of human body sweating in the new, and 20.C were measured by using this method, 25 degrees and 28 degrees 3 ambient temperature, 8 subjects were on the treadmill based on 0.90m/s (2mi/h), 1.78m/s (4mi/h) and 2.68m/s (6mi/h) 15min speed running after the sweat rate. Then using the paired t test on 8 subjects per unit area of the sweating rate results were analyzed and found that the temperature and intensity of environment on human sweat rate per unit area significantly affected the environment temperature were 20 degrees, 25 degrees and 28 degrees of strength and activity were 0.90m/s, 1.78m/s and 2.68m/s, the scope of human sweat rate per unit area is 1.605 ~ 681.100 g/ (H - m2), but also demonstrated the clothing weight gain is measured in human sweat rate An effective method.
The simultaneous determination of sweat rate also examined 10 heart and lung function index, by Pearson correlation analysis, respiratory exchange ratio, 02 equivalent ventilation, C02 ventilation were equivalent and systemic sweat rate per unit area is not related to the other 7 physiological indexes were significantly positive with sweat rate per unit area the related degree of order: oxygen uptake and minute ventilation volume C02 exhaled oxygen uptake relative metabolic equivalent tidal volume respiratory frequency. This shows that the heart and lung function monitoring indexes can be roughly describe the comprehensive degree of heat and activity intensity, and forecast the sweat rate per unit area.
In addition, this paper also use the method of filter paper were measured 20 degrees, 25 degrees and 28 degrees 3 environmental temperature, 1 male subjects were on a treadmill with 0.90m/s, 1.78m/s and 2.68m/s local sweating speed running after 15min of the upper parts of the 10 rate. Through paired t test showed that confidence 90%, according to the significant differences in the size and sweat rate per unit area can be divided into 4 groups of 10 body parts, and the order is: the lower part of the left upper abdominal and back left back central chest, scapula and abdomen shoulder, upper arm, middle and upper spine.
In addition to 20 DEG 0.90m/s and 20 DEG C, 1.78m/s when the subjects had no significant differences between the area of local unit body sweat rate, the other paired t test results show that the environmental temperature and activity intensity on the upper body of local sweat rate per unit area significantly affected the ambient temperature are 20 degrees, 25 degrees and 28 degrees of strength and the activities were 0.90m/s, 1.78m/s and 2.68m/s, the subjects of 10 parts of the body sweat rate per unit area in the range of 2 ~ 1418.4g/ (H - m2).
The body and body parts for the study of sweating sweat rate determination under the condition of clothing thermal comfort provides basic physiological data, to provide clues and improve the sweating sweating difference on the upper part of the body awareness adjustment mechanism, for sports apparel structure design, to provide reference for the selection and design of fabric sweating manikin.
