Study on subjective sensation and physiological reaction with high physical activity influenced by air temperature of stadium

Abstract

As the main venue for sports training and competition, the thermal environment of a stadium directly could affect the comfort and health of a moving body and sports performance. In this study, the quantitative relationship between ambient temperature and subjective sensation evaluation was established by monitoring the actual thermal sensation evaluation, fatigue sensation cognition and physiological response with high physical activity, under different conditions of ambient temperature. The results show that 90% of subjects can actually accept an ambient temperature range of 18.6°C–26°C. This is 2°C higher than the maximum recommended range in the ISO 7730:2005 thermal comfort standard, reflecting a strong tolerance of the moving human body to low or high temperature environments. A high temperature environment could cause exercise fatigue to occur prematurely. Moreover, the study suggests that the critical point for early occurrence of fatigue sensation in a moving human body is 28°C. The relationship between the environmental temperature and the physiological response was evaluated by mean skin temperature, blood pressure and heart rate of the human body. These are used as evaluation indexes of physiological parameters. Ambient temperature has a significant effect on the objective physiological response of the moving human body, which coincides with the subject’s definition of subjective sensory evaluation to the ambient temperature.

Influence of phase change materials on thermal comfort, greenhouse gas emissions, and potential indoor air quality issues across different climatic regions: A critical review

“…The degree of perceived human thermal sensation levels could be influenced by the type of physical activity, whether sedentary or active 150,151 . Sensitivity to thermal sensation or comfort is highly dependent on the amount of internal heat stress generated by the muscle, which is also partly controlled by the level of physical activity 152 .…”

“…The degree of perceived human thermal sensation levels could be influenced by the type of physical activity, whether sedentary or active. 150,151 Sensitivity to thermal sensation or comfort is highly dependent on the amount of internal heat stress generated by the muscle, which is also partly controlled by the level of physical activity. 152 This implies that it is important to evaluate how the PCM vest affects the human thermal comfort level under a sedentary lifestyle based on the summarised studies compiled in Table 3.…”

Thermal sensation under high-intensive exercise in naturally ventilated gymnasiums in hot-humid areas of China: Taking basketball players for example

“…Very few studies focused on the thermal sensation of sports players in sports buildings undertaking sports and exercises. [16][17][18] However, thermal sensation study in the sport environment is necessary to pursue health and wellbeing and to attain a high quality of life for human subjects. Based on this background, this study undertakes a research into the thermal sensation of basketball players in gymnasium during sport activity such as a basketball game.…”

“…Li et al 25 conducted experimental research on strenuous exercise (3.5-5.0 met) and indicated that the heart rate and wrist skin temperature can be utilized for evaluating the thermal sensation. Xiao et al 18 monitored the subjective sensation and physiology with high physical activity under different ambient temperature and found significant effect of ambient temperature on objective response. Research from Henriques et al, 26 Zhu et al 27 and Zhai et al 28 analysed the relationship between thermal comfort and different levels of intensity.…”
