| description | <h3>Purpose</h3><p dir="ltr">Different strategies for near-infrared spectroscopy (NIRS)-derived muscle oxidative capacity assessment have been reported. This study compared and evaluated (I) approaches for averaging trials; (II) NIRS signals and blood volume correction equations; (III) the assessment of vastus lateralis (VL) and tibialis anterior (TA) muscles in two fitness levels groups. </p><h3>Methods </h3><p dir="ltr">Thirty-six participants [18 chronically trained (CT: 14 males, 4 females) and 18 untrained (UT: 10 males, 8 females)] participated in this study. Two trials of twenty transient arterial occlusions were performed for NIRS-derived muscle oxidative capacity assessment. Muscle oxygen consumption (<i>V</i>˙O<sub>2</sub>m) was estimated from deoxygenated hemoglobin (HHb), corrected for blood volume changes following Ryan (HHbR) and Beever (HHbB) equations, and from oxygen saturation (StO<sub>2</sub>) in VL and TA. </p><h3>Results </h3><p dir="ltr">Superimposing or averaging <i>V</i>˙O<sub>2</sub>m or averaging the rate constants (<i>k</i>) from the two trials resulted in equivalent k values [two one-sided tests (TOST) procedure with 5% equivalence margin—<i>P</i> < 0.001]. Whereas HHbR (2.35 ± 0.61 min−<sup>1</sup>) and HHbB (2.34 ± 0.58 min<sup>−1</sup>) derived k were equivalent (P < 0.001), StO2 derived k (2.81 ± 0.92 min−1) was greater (P < 0.001) than both. <i>k </i>values were greater in CT vs UT in both muscles (VL: + 0.68 min−<sup>1</sup>, <i>P</i> = 0.002; TA: + 0.43 min−1, <i>P</i> = 0.01). </p><h3>Conclusion </h3><p dir="ltr">Different approaches for averaging trials lead to similar k. HHb and StO2 signals provided different k, although different blood volume corrections did not impact k. Group differences in k were detected in both muscles.</p><h2>Other Information</h2><p dir="ltr">Published in: European Journal of Applied Physiology<br>License: <a href="https://creativecommons.org/licenses/by/4.0" target="_blank">https://creativecommons.org/licenses/by/4.0</a><br>See article on publisher's website: <a href="https://dx.doi.org/10.1007/s00421-024-05421-6" target="_blank">https://dx.doi.org/10.1007/s00421-024-05421-6</a></p> |
