Architectural gear ratio, also called anatomical gear ratio (AGR) is a feature of pennate muscle defined by the ratio between the longitudinal strain of the muscle and muscle fiber strain. It is sometimes also defined as the ratio between muscle-shortening velocity and fiber-shortening velocity. [1] AGR = ε x /ε f
Muscle contractions can be described based on two variables: force and length. Force itself can be differentiated as either tension or load. Muscle tension is the force exerted by the muscle on an object whereas a load is the force exerted by an object on the muscle. [1]
Since work is defined as force multiplied by displacement, the area of the graph shows the mechanical work output of the muscle. In a typical work-generating instance, the muscle shows a rapid curvilinear rise in force as it shortens, followed by a slower decline during or shortly before the muscle begins the lengthening phase of the cycle.
Eccentric, concentric, and isometric phases are all distinct parts of most exercises you do in your workouts. Here's what they mean and how to use them. Eccentric, concentric, and isometric phases ...
The linear eccentricity of an ellipse or hyperbola, denoted c (or sometimes f or e), is the distance between its center and either of its two foci. The eccentricity can be defined as the ratio of the linear eccentricity to the semimajor axis a : that is, e = c a {\displaystyle e={\frac {c}{a}}} (lacking a center, the linear eccentricity for ...
A metric space defined over a set of points in terms of distances in a graph defined over the set is called a graph metric. The vertex set (of an undirected graph) and the distance function form a metric space, if and only if the graph is connected. The eccentricity ϵ(v) of a vertex v is the greatest distance between v and any other vertex; in ...
The muscle synergy hypothesis is based on the assumption that the central nervous system controls muscle groups independently rather than individual muscles . [16] [17] The muscle synergy hypothesis presents motor control as a three-tiered hierarchy. In tier one, a motor task vector is created by the central nervous system.
It can also be defined as a curve whose points are at a constant normal distance from a given curve. [1] These two definitions are not entirely equivalent as the latter assumes smoothness, whereas the former does not. [2] In computer-aided design the preferred term for a parallel curve is offset curve.
