Abstract

The purpose of this study was to investigate the effects of color temperature of lighting on physiological functions and subjective performance during physical exercise, in order to provide physiological grounds for selecting suitable lighting conditions for physical exercise. The experiments were conducted in a lighting laboratoiy controlled at a temperature of 25℃ and relative humidity of 50-60%. The illuminance level was maintained at 1000 lx, and three color temperature levels (3000 K, 5000 K and 7500 K) provided a total of three lighting conditions. Ten participants' oxygen uptake, heart rate (FIR), systolic blood pressure and diastolic blood pressure (DBP) were collected before, during and after successive exercise of 50W and 100W The rectal temperature (Tre), skin temperature at 7 points and subjective performance were also measured, and the mean skin temperature and mean arterial blood pressure (MAP) were calculated. The results of FIR, DBP and MAP at 7000 K were significantly higher than those at 3000 K and 5000 K, and the speed of recovery after exercise was slower at 7000 K than at 3000 K or 5000 K. Compared with other conditions, the Tre was significantly increased at 3000 K, and recovery took longer at 3000 K. The results of subjective performance showed that "brightness" at 7000 K and "fatigue" immediately after the exercise were the highest, while "relaxation" immediately after the exercise was the lowest. We also found that "sleepiness" was the highest and "concentration" was the lowest at 3000 K. On the other hand, "motivation" at 5000 K was the highest. Our results indicated that 5000 K is the best color temperature for alighting source during exercise for maintaining autonomic stability and psychological balance.
