Oxygenation kinetics of sixteen young adult males was measured with two NIRS probes attached to the flexor carpiradialis muscle during gripping for 3 min. One probe (channel 1) was attached at one-third the length of a line from the medial epicondyle of the humerus to the styloid process of radius. Another probe (channel 2) was attached at the palmaris longus. Although the cross-correlation coefficients for the two probe placements regarding oxygenated hemoglobin (oxy-Hb/Mb), deoxygenated hemoglobin (deoxy-Hb/Mb) and tissue oxygenation saturation (StO2) were low (rxy, 0.119-0.405), Pearson's correlation coefficients for the times to reach almost steady state for these parameters were very high (oxy-Hb/Mb, r=0.878; deoxy-Hb/Mb, r=0.769; StO2, r=0.843; p<0.05). The difference of oxygenation kinetics between the probe placements may reflect the difference of fiber recruitment characteristics in the flexion muscle group. In conclusion, to obtain a stable measurement, it is important that the NIRS probe is placed at the same anatomical point. © Springer-Verlag Italia 2007., 金沢大学人間社会研究域人間科学系, 福井大学医学部},
