Abstract

This study analyzes the heart rate and voice response of young students while walking or listening to sounds based on 1/f (f=frequency) fluctuation using FFT spectral analysis. There was more positive 1/f fluctuation in heart rate response in normal walking or while listening to comfortable sounds than under stressful conditions, whereas the response was negatively influenced by walking with a heavy bag or while listening to noisy sounds. This study provides a useful method for preventive medicine, physical fitness, and a means for young subjects to maintain a state of well-being.
