Near-Infrared Spectroscopy Is Promising to Detect Iliac Artery Flow Limitations in Athletes: A Pilot Study

Table 1

Exercise information in NP and CP. values of 9 healthy athletes measured in CP; ^∗Abnormal values for ABI are <0.54 and a pressure difference of >23 mm Hg or <-23 mm Hg; ^∗∗First measurement possible after four minutes which was 0.54 [3].
