How does Valsalva Wave Pro measure “coherence”?
Valsalva Wave Pro allows us to train coherence of the Valsalva Wave, the heart rate, or both simultaneously. The primary “coherence” training approach involves breathing synchronously at the frequency of .085 Hz., essentially 5 breaths per minute in such a way as to align the Valsalva Wave and heart rate so that they are approximately 180 degrees out of phase, and, spectral power is centered around .085 Hz. See Valsalva Wave option #22 or Heart Rate option #19.
