Long-range correlations in human standing
M Duarte, VM Zatsiorsky - Physics Letters A, 2001 - Elsevier
We estimated long-range correlations in the dynamics of sway during prolonged human
standing. Two methods were used in this estimation: detrended fluctuation analysis (DFA)
and power spectral analysis. Both methods yielded similar results: we observed long-range
correlations with single scaling exponents over a broad range, from 10 s to 10 min, of
standing.
