Abstract
The physiological effects of walking in Shinjuku Gyoen were examined by investigating heart rate and heart rate variability (HRV). Subjective feelings of being "comfortable," "natural," and "calm" were also assessed by a questionnaire. The subjects included 18 male university students aged 20-23 years (mean±SD: 21.0±0.8 years). Physiological measurements were recorded while the subjects walked a predetermined course in Shinjuku Gyoen and around Shinjuku station (control) for 14min. The results were as follows: (1) the power of the In HF component of the HRV was significantly higher, (2) heart rate was significantly lower, and (3) "comfortable," "natural," and "calm" feelings were significantly higher in the subjects while walking through Shinjuku Gyoen than while walking around Shinjuku station.
