The purpose of this study was to investigate the effect of the prolonged exercise on autonomic nerves system activity and ventilation responses. Nine healthy non-smoking females participated in this study. Before and after 24h of the prolonged exercise (20-30km jogging or brisk walking), they performed 6 minutes walking on treadmill by a fixed speed of 100meters/min and the expired air was collected to assess ventilation. They also underwent 2-channel 2-hour Holter recordings at least 2h to assess autonomic nerves system (ANS) activity by heart rate variability (HRV). There were no differences between the mean values in any of the measurements except V^^・E/ V^^・CO2 decreasing (p<0.05). Total number of RR50 and HF values were significantly lower (p<0.05, p<0.05) and LF/HF ratio were significantly higher (p<0.05). These results suggest the prolonged exercise affect to ANS activity and exercise ventilation may be concerned with ANS.
