“…In that study, the baseline values were not the same as those of our study (68 vs. 63.2%) but certainly lower than the values obtained with the INVOS ® device. Another study reported 4-wavelength NIRS values lower than the INVOS ® device values, which implies the relative lower baseline 4-wavelength NIRS value, although the exact reason is uncertain [25]. Theoretically, NIRS devices that use more wavelengths would be more accurate and have enhanced tissue recognition [21].…”

Near-infrared spectroscopy devices can measure peripheral tissue oxygen saturation (StO 2). This study aims to compare StO 2 using INVOS ® and different O3™ settings (O3 25:75 and O3 30:70). Twenty adults were recruited. INVOS ® and O3™ probes were placed simultaneously on 1 side of forearm. After baseline measurement, the vascular occlusion test was initiated. The baseline value, rate of deoxygenation and reoxygenation, minimum and peak StO 2 , and time from cuff release to peak value were measured. The parameters were compared using ANOVA and Kruskal-Wallis tests. Bonferroni's correction and Mann-Whitney pairwise comparison were used for post hoc analysis. The agreement between StO 2 of devices was evaluated using Bland-Altman plots. IN-VOS ® baseline value was higher (79.7 ± 6.4%) than that of O3 25:75 and O3 30:70 (62.4 ± 6.0% and 63.7 ± 5.5%, respectively, p < 0.001). The deoxygenation rate was higher with IN-VOS ® (10.6 ± 2.1%/min) than with O3 25:75 and O3 30:70 (8.4 ± 2.2%/min, p = 0.006 and 7.5 ± 2.1%/min, p < 0.001). The minimum and peak StO 2 were higher with INVOS ®. No significant difference in the reoxygenation rate was found between the devices and settings. The time to reach peak after cuff deflation was faster with INVOS ® (both p < 0.001). Other parameters were similar. There were no differences between the different O3™ settings. There were differences in StO 2 measurements between the devices, and these devices should not be interchanged. Differences were not observed between O3™ device settings.

Introduction: Near infrared spectroscopy (NIRS) is a non-invasive technique that is used in the assessment of tissue oxygenation and the monitoring of physical activity. Objective: To determine the influence of sexual, anthropometric and ergospirometric factors on muscle oxygenation of the quadriceps and gastrocnemius, obtained by NIRS during a stress test. Methods: Twenty healthy subjects participated in this study (10 women). Two Humon Hex® devices were placed on the dominant side of the quadriceps and gastrocnemius muscles to measure muscle oxygen saturation (SmO2). The stress test was performed on a treadmill with electrocardiographic control and measurement of oxygen consumption. SmO2 was obtained at rest and after maximum effort during the stress test. In addition, the height, weight, skinfold and waist contour were measured. Bioimpedance was used to obtain the percentages of fat mass and muscle mass, which were used to calculate the relative fat mass (RFM). Results: The SmO2 of both muscles at rest is higher in males than in females. At maximum effort, the SmO2 of the quadriceps is similar in both groups. The SmO2 of both muscles is positively related to height, body mass, percentage of mass muscle and waist contour, and negatively with percentage of mass fat, RFM and skinfold thickness. The negative correlation between fat percentage and oxygen saturation is more evident in females. It was observed that the variables that quantify maximum effort are not related to the SmO2 values, except for the correlation between HR max and SmO2 of the gastrocnemius muscle in males. Conclusion: The SmO2 of recreational athletes is influenced by the location of the device and the fat mass of the subjects. The biggest differences between the sexes are in the gastrocnemius muscle.
