Effects of different exercise types on outdoor thermal comfort in a severe cold city

The promotion of China's National Fitness Program has caused an upsurge in the construction of outdoor sports venues and sparked an interest in research on the thermal comfort of people exercising outside. The design of exercise facilities and parks is usually function-oriented, and the spatial layout and arrangement of exercise paths are based on the exercise type. However, few studies compared the thermal comfort of different exercise types. This study investigated seasonal differences in thermal sensation, thermal comfort, and other influencing factors among people who engaged in various types of exercise in a severe cold city in China. The results showed significant differences in thermal comfort among the different exercise types. The acceptable thermal range of exercising people is greater than that of the resting ones. In the cold season, the thermal comfort of different exercise types had a significant correlation with thermal sensation, but not with humidity and wind sensations. On the other hand, the thermal comfort of jogging respondents was more affected by humidity, wind, and sun sensations during the hot season. The modified UTCI range of thermal stress category was proposed as a design reference for the thermal environment of outdoor exercise venues. Overall, this study can help enrich and guide outdoor thermal comfort research in severe cold regions and aid the design of urban exercise spaces.
