1. A biological information measurement device comprising:
heart rate counting means for measuring an HR value indicating a heart rate on a basis of heart-rate data obtained by capturing heartbeats when a subject to be measured exercises;
analysis means for performing power spectrum analysis on a heart rate variability frequency of the heart-rate data to calculate an LF value which is an integral value of low frequency components; and
detection means for obtaining an HR/LF value by dividing the HR value by the LF value with respect to exercise intensity of the subject to be measured.
