The purpose of this investigation is to clarify the autonomic response to the cold pressor test (CPT) by analyzing the power spectrum of the heart rate variability (HRV). The subjects of this investigation were 10 males who were aged 16-17 years.
The results of this investigation are summarized as follows:
1）The parasympathetic nerve activity of the subjects decreased significantly in CPT.
2）The sympathetic nerve activity of the subjects increased significantly in CPT.
3）It is concluded from the findings that the CPT serves an effective method of testing autonomic response of young people.
