dc.description.abstract
It has been shown that statistical persistence in stride intervals
characteristics exist during walking, running and cycling and were speed-
dependent among healthy young adults. The purpose of this study was to
determine if such statistical persistence in stride time interval, stride
length and stride speed also exists during self-paced continuous stairmill
climbing and if the strength is dependent on stepping rate. Stride time,
stride length, and stride speed were collected from nine healthy participants
during 3 min of stairmill climbing at 100, 110, and 120% of their preferred
stepping rate (PSR) and 5 min of treadmill walking at preferred walking speed
(PWS). The amount of variability (assessed by standard deviation and
coefficient of variation) and dynamics (assessed by detrended fluctuation
analysis and sample entropy) of the stride time, stride length, and stride
speed time series were investigated. The amounts of variability were
significantly higher during stairmill climbing for the stride time, stride
length, and stride speed and did only change with increased stepping rate for
stride speed. In addition to a more irregular pattern during stairmill
climbing, the detrended fluctuation analysis (DFA) revealed that the stride
length fluctuations were statistical anti-persistent for all subjects. On a
group level both stride time and stride speed fluctuations were characterized
by an uncorrelated pattern which was more irregular compared to that during
treadmill walking. However, large inter-participant differences were observed
for these two variables. In addition, the dynamics did not change with
increase in stepping rate.
