南京地区人体舒适度特征分析及其对田径运动成绩的影响
Analysis of human comfort characteristics and its impact on athletics performance in Nanjing
摘要
Abstract
Human comfort is an important indicator of urban livability,and it is the response of human organs and skin and other receptors to environment changes through the nervous system.Human comfort is directly affected by meteorological factors such as temperature,humidity and wind speed.In this paper,the changes of human comfort indicators,including HI(Heat Index),Humidex,WBGT,WCI,in Nanjing area were analyzed by using meteorological observations from 2015 to 2021 at the SORPES station located on Xianlin Campus of Nanjing University.The interannual variation magnitude of each index is basically similar,ranging from 15 to 20.The annual and monthly trends of each index are highly consistent with the temperature trend,because in the definition and calculation of each index,temperature is the meteorological factor with the greatest weight,and on this basis,it is revised by humidity,wind speed and other factors.From the perspective of the probability density of each index interval,the probability density distribution of each index has a weak"three-peak type",which is caused by the superposition of the"bimodal type"in autumn and the"unimodal type"in other seasons.The"bimodal"distribution of each index in autumn is mainly caused by the large temperature difference between day and night.From the perspective of statistical characteristics,the human body perception in Nanjing is mainly comfortable,and the probability of hot environment risk is much greater than that of cold environment risk.The risk probability is slightly higher with Humidex than that is with HI.Using the training records of 200 m sprint of athletes from Nanjing University,the impact of human comfort on outdoor sports was analyzed,and it was found that there are great individual differences in the sensitivity response of different athletes to the thermal environment.That is 30％of the subjects are affected by the thermal environment comfort,and 10％of the subjects are significantly affected by the thermal environment comfort,and the sensitivity of female athletes is higher than that of male athletes.The results show that the impact of environmental human comfort on athletes in future sports training cannot be ignored,entailing more attention and research.关键词
