Gait timing dynamics of treadmill and overground running were compared. Nine trained runners ran treadmill and track trials at 80, 100, and 120% of preferred pace for 8 min. each. Stride time series were generated for each trial. To each series, detrended fluctuation analysis (DFA), power spectral density (PSD), and multiscale entropy (MSE) analysis were applied to infer the regime of control along the randomness–regularity axis. Compared to overground running, treadmill running exhibited a…

A non-linear analysis of running in the heavy and severe intensity domains.
TLDR
The findings suggest running above CV results in increased movement complexity and variability, particularly at the hip, during treadmill running, consistent between heavy and severe intensity domains.
Is Motorized Treadmill Running Biomechanically Comparable to Overground Running? A Systematic Review and Meta-Analysis of Cross-Over Studies
TLDR
Spatiotemporal, kinematic, kinetic, muscle activity, and muscle–tendon outcome measures are largely comparable between motorized treadmill and overground running.
Dynamics of Stride Interval Characteristics during Continuous Stairmill Climbing
TLDR
The detrended fluctuation analysis (DFA) revealed that the stride length fluctuations were statistical anti-persistent for all subjects and both stride time and stride speed fluctuations were characterized by an uncorrelated pattern which was more irregular compared to that during treadmill walking.
Lower between-limb asymmetry during running on treadmill compared to overground in subjects with laterally pronounced knee osteoarthritis
TLDR
An assessment of symmetry may differ depending on the ground type (treadmill versus overground) and b) treadmill running may be more suitable for patients with KOA related gait asymmetries are suggested.
The assessment of fatigue-related changes in stride mechanics, variability and long-range correlations in recreational and elite distance runners using foot-mounted inertial sensors
This thesis was designed to assess stride mechanics, variability and long-range correlations during running, as well as their relationship with fatigue and skill level. For this purpose, three
An Assessment of Running Power as a Training Metric for Elite and Recreational Runners
TLDR
Running power, calculated via the Stryd Power Meter, is not sufficiently accurate as a surrogate of metabolic demand, particularly in the elite population, however, in a recreational population, this training tool could be useful for feedback on several running dynamics known to influence running economy.

Local dynamic stability versus kinematic variability of continuous overground and treadmill walking.
TLDR
Treadmill walking was associated with significant changes in both variability and local stability, and motorized treadmills may produce misleading or erroneous results in situations where changes in neuromuscular control are likely to affect the variability and/or stability of locomotion.
Kinematic variability, fractal dynamics and local dynamic stability of treadmill walking
TLDR
Treadmill induced a less correlated pattern in the stride intervals and increased gait stability, but did not modify kinematic variability in healthy subjects, which could be due to changes in perceptual information induced by treadmill walking that would affect locomotor control of the gait and hence alter non-linear dependencies among consecutive strides.
Treadmill walking as an external pacemaker to improve gait rhythm and stability in Parkinson's disease
TLDR
It is suggested that the treadmill may be acting as an external cue to enhance gait rhythmicity and reduce gait variability in Parkinson's disease subjects.
