Figure 2. An example of the changes in Oxy-Hb levels detected by NIRS. The Oxy-Hb level recorded at rest was defined as 100%, and the minimum Oxy-Hb plateau level recorded after 6 minutes’ arterial occlusion was defined as 0%. Furthermore, repeated arterial occlusion was performed after the exercise, and the time it took for the oxygen consumption rate to return to 63% of its resting value was calculated.
