The importance of stride length and stride frequency in middle distance running

African Journal for Physical, Health Education, Recreation and Dance, 2004
From the literature it is evident that there is no clarity whether or not middle distance runners should use shorter or longer stride lengths and higher stride frequencies. To address this problem, 30 North-West Province road runners were selected on a stratified basis according to their performances.

Intentional on-line adaptation of stride length in human walking

Experimental Brain Research, 2000
The intentional control of stride length is a fundamental basis for the adaptation of the stride to environmental constraints (obstacle avoidance, for example). Controlling the propulsive forces during the stance and/or controlling the pendular movement of the oscillating leg constitute the two potential and non-exclusive mechanisms underlying ...

Human pose and stride length estimation

2021
In this thesis, we develop Computer Vision methods for Human body pose and stride length estimation. We first describe a framework for estimating the stride length of a walking subject from video using a multi-view camera setup. We specifically look into its utility in diagnosing Parkinson's disease.

Stride length in distance running

Medicine & Science in Sports & Exercise, 1989
The preferred stride frequency (SF) and stride length (SL) of male recreational distance runners were measured on a level treadmill under a variety of conditions over the typical distance running speed range of 3.15-4.12 m.s-1. At a given speed, the correlation coefficients between the subjects' anthropometric variables (APV) (such as stature, leg ...

Abnormalities in the stride length‐cadence relation in parkinsonian gait

Movement Disorders, 1998
AbstractThe purpose of this investigation was to clarify abnormalities in the stride length‐cadence relation in gait hypokinesia in Parkinson's disease (PD). A second aim was to investigate the effect of levodopa medication on the foot‐step pattern. In the first experiment, 20 subjects with idiopathic PD and 20 age‐, sex‐, and height‐matched controls ...

Modelling Stride Length and Stepping Frequency

2016
A pedestrian motion model must be calibrated to measured data and validated against observations to achieve predictive power for the simulations. The relationship between the speed of pedestrians and the density of a crowd or the flow through bottlenecks are widely accepted as important characteristics of pedestrian movement.

Effects of stride length alteration on racewalking economy.

Canadian journal of applied sport sciences. Journal canadien des sciences appliquees au sport, 1987
This study investigated the effects of stride length (SL) manipulation on racewalking economy in 7 competitive racewalkers. Following two test sessions in which VO2 max and freely-chosen stride length (FCSL) were determined, each subject completed 6-min racewalking bouts at five randomly-ordered SL conditions (FCSL and -10%, -5%, +5%, and +10% of leg ...

Effects of stride length on the mechanics of the tibiofemoral joint

IEEE 30th Annual Northeast Bioengineering Conference, 2004. Proceedings of the, 2004
It is purported that a sagittal tibiofemoral joint extension angle can be found for an individual, regardless of physical predisposition, that minimizes gliding and compression forces acting on the joint, and in turn, optimizes the leg's ability to absorb shock during the loading phase (heel plant) portion of the walking gait cycle.

Stride length and speed for adults, children, and fossil hominids

American Journal of Physical Anthropology, 1984
AbstractResearch workers studying the relationship between stride length (L) and speed (u) in human walking have often expressed their results as multiples of stature (h): they have given values of L/h and u/h. They have claimed or implied that this takes account of differences of body size and that L/h should be the same function of u/h for people of ...

Long-Range Correlations of Stride Time, Stride Length and Stride Velocity during Feedback-Controlled Treadmill Walking

2014
The gait fractal dynamics during between conventional treadmill (CTM) and feedback-controlled treadmill (FTM) walking were compared in this study. Seven healthy male subjects performed for 5 min walking with each treadmill condition. FTM can be tuned its belt speed to walker’s speed, which controls belt speed by walker’s anterior-posterior location by ...
