  1. Mean velocity was analyzed using time periods of 12.9 s. SD and RMSSD are given as % of the mean. For the Fourier analysis results are presented as variance in the high frequency range divided by the variance in the low frequency range. All data are given as mean ± SD
  2. t tests: * p < 0.05, ** p < 0.01, *** p < 0.001
