Abstract

This study aimed to investigate the athletic differences in the characteristics of the photoplethysmographic (PPG) pulse shape. 304 athletes were enrolled and divided into three subgroups according to a typical sport classification in terms of the maximal oxygen uptake (MaxO(2)_low, MaxO(2)_middle and MaxO(2)_high groups) or the maximal muscular voluntary contraction (MMVC_low, MMVC_middle, and MMVC_high groups). Finger PPG pulses were digitally recorded and then normalized to derive the pulse area, pulse peak time T-p, dicrotic notch time T-n, and pulse reflection index (RI). The four parameters were finally compared between the three subgroups categorized by MaxO(2) or by MMVC. In conclusion, it has been demonstrated by quantifying the characteristics of the PPG pulses in different athletes that MaxO(2), but not MMVC, had significant effect on the arterial properties.
