Pearson correlations between electromyographic and cerebral/muscle hemodynamic responses during intermittent contractions of the biceps brachii at three intensities (N = 11, critical ‘r’ value = 0.58).
| Intensity | Cerebral HbO2 | Cerebral HHb | Muscle HbO2 | Muscle HHb |
|---|---|---|---|---|
| RMS at 20% MVC | 0.44 | 0.03 | −0.16 | 0.25 |
| RMS at 40% MVC | 0.51 | −0.05 | −0.19 | 0.09 |
| RMS at 60% MVC | 0.49 | −0.11 | −0.25 | 0.16 |
None of the correlations were significant at P < 0.05.
