Time was normalized by average stride time for each subject and each condition.
Coefficient of variation (CoV) (CoV = (standard deviation/ mean) × 100) of stride time (i.e., gait cycle duration defined as the time elapsed between the first contact of two consecutive footsteps of the same foot) was used as a measure of STV.
Outcome measures include stride related measures such as mean and coefficient of variation of stride time, and dynamic measures regarding the magnitude, smoothness, predictability and local stability of trunk accelerations.
Thus, means and standard deviations (SD) of stride time, stride length, stride velocity, and stride width will be computed.
Measurements tested included walking speed, step length, stride length, base of support, step time, stride time, swing time, stance time, single and double support times, and toe in-toe out angle.
For example, one study of the effects of physiologic aging on gait found stride time variability was essentially identical in a group of healthy young adults (mean age 24.6 years) and healthy older adults (mean age 75.7 yrs) [ 31], with values similar to those observed in the present study.
And sang the words, "A modern-day warrior / mean, mean stride / Today's Tom Sawyer / mean, mean pride").. Are we finished with quiet time?
The mean relative DTC at fast walking speed was 26.4 ± 17.6% (stride velocity), 31.4 ± 71.6% (stride time), and 12.8 ± 8.8% (stride length).
The dependent variables were: (1) acute exercise tolerance (rating of perceived dyspnoea, heart rate, and oxygen saturation), and (2) long-term functional performance (timed-up-and-go test, 5-chair stands test, stride length, stride time, and stride velocity).
