Walking and running, the two basic gaits used by man, are very complex movements. They
can, however, be described using two simple models: an inverted pendulum and a spring …

The ability to predict the energy cost of load carriage is important to various disciplines and
applications including anthropology, exercise physiology, humanitarian aid, and dismounted …

Background. The reasons behind the development of future pathology in individuals with
anterior cruciate ligament deficiency are unknown. This is due to the lack of appropriate …

Objective. The evaluation of variability of biological rhythmic activities through measures
such as Approximate Entropy (ApEn) has provided important information regarding …

Previous studies suggested that the small fluctuations present in movement patterns from
one stride to the next during walking can be useful in the investigation of various …

Elderly adults consume more metabolic energy during walking than young adults. Our study
tested the hypothesis that elderly adults consume more metabolic energy during walking …

The aim of this study was to evaluate stride-to-stride variability of the lower extremity during
walking in individuals with and without chronic ankle instability (CAI) using a nonlinear …

Humans do not generally walk at constant speed, except perhaps on a treadmill. Normal
walking involves starting, stopping and changing speeds, in addition to roughly steady …

INTRODUCTION: The temporal structure of gait variability has shown that healthy human
gait exhibits long-range correlations and deterministic properties which allow the …

Shuttle runs can be used to study the physiological responses in sports (such as basketball)
characterized by sprints (accelerations/decelerations) and changes of direction. Purpose: To …
