Horizontal cycling (H)Vertical cycling (V)
A

The original signals

Almost overlapping

The shared cadence dominates the full waveform.

B

The D3 wavelet detail

2.59× RMS

Isolating a scale reveals differences already in the signal.

Horizontal and vertical cycling are shown using two unaltered five-second windows of participant 8’s left-leg z-axis angular velocity. The raw signals have a Pearson correlation of 0.992; wavelet decomposition reveals differences within these otherwise similar signals.
