Angular momentum in human walking.
Angular momentum is a conserved physical quantity for isolated systems where no external moments act about a body's center of mass (CM). However, in the case of legged locomotion, where the body interacts with the environment (ground reaction forces), there is no a priori reason for this relationship to hold. A key hypothesis in this paper is that angular momentum is highly regulated throughout...
متن کاملSpin Angular Momentum in Human Walking: Magnitude, Dimensionality and Distribution
Short Title: Angular momentum in human walking Summary In this study we examine the relative size of whole-body spin angular momentum in human walking, and the dimensionality and distribution of intersegment angular momentum. Using a 16-segment human model and kinetic and kinematic gait data, we examine whole-body rotational dynamics for ten study participants walking at self-selected speeds. A...
متن کاملAngular momentum of walking at different speeds.
Recently, researchers in robotics have used regulation of the angular momentum of body segments about the total body center of mass (CoM) to develop control strategies for bipedal gait. This work was spurred by reports finding that for a "large class" of human movement tasks, including standing, walking, and running the angular momentum is conserved about the CoM. However, there is little data ...
متن کاملWhole-body angular momentum in incline and decline walking.
Angular momentum is highly regulated over the gait cycle and is important for maintaining dynamic stability and control of movement. However, little is known regarding how angular momentum is regulated on irregular surfaces, such as slopes, when the risk of falling is higher. This study examined the three-dimensional whole-body angular momentum patterns of 30 healthy subjects walking over a ran...
متن کاملMuscle contributions to frontal plane angular momentum during walking.
The regulation of whole-body angular momentum is important for maintaining dynamic balance during human walking, which is particularly challenging in the frontal plane. Whole-body angular momentum is actively regulated by individual muscle forces. Thus, understanding which muscles contribute to frontal plane angular momentum will further our understanding of mediolateral balance control and has...
