closed chain

This means that the closed chain does not wind around points outside the region.

Closed chain exercises tend to offer more "functional" athletic benefits such as jumping and squatting.

Modern tracks are built from modular chain links which together compose a closed chain.

Four intersecting equal circles arranged in a closed chain are sufficient to determine an equilateral pentagon.

Closed chain exercises are considered safer and more "functional" compared to open chain exercises.

There are two important special cases: (i) a simple open chain, and (ii) a simple closed chain.

A four-bar linkage, also called a four-bar, is the simplest movable closed chain linkage.

Closed chain cyanines:

Such a combination is called a closed chain, and one defines an integral along the chain as a linear combination of integrals over individual paths.

An example of a simple closed chain is the RSSR spatial four-bar linkage.

Other leg strengtheners include "closed chain" exercises like the Stairmaster, leg presses and treadmill, where the leg is working in tandem with the upper body.

Linkages may be constructed from open chains, closed chains, or a combination of open and closed chains.

Stamps from the 1937 "Historical issue" and 1942 definitives and airmail stamps were surcharged in red or black with the design of a closed chain and new values.

On election day itself a mother who had two children at one of the schools which was to be closed chained herself outside of a polling station to protest against the closures.

For a simple closed chain, n moving links are connected end-to-end by n+1 joints such that the two ends are connected to the ground link forming a loop.

Closed chain exercises are often compound movements, that generally incur compressive forces, while open-chain exercises are often isolation movements that promote more shearing forces.

In this scene the participants form a closed chain; the prayer of the orant forms links between the hunter and the sacred animal, represented by the snake man and game respectively.

They stepped up the strength building with "closed chain" exercises - squats, quarter-squats and lunges - in which the feet are planted on the ground to reduce the stress on the knee.

Using mankind as an example, in closed chain function, ground reactive forces, a dynamic architecture and a dynamic equilibrium of forces around joint axes impact the posture to produce tissue stress.

I moved a little, to feel the tiny metal tag, slung on its tiny closed chain, the chain closed about my collar, move delicately, lightly, on my skin, just below my neck.

These loops and surfaces have no analogy in complex spaces, for example a set of complex lines and points may form a closed chain of connections, but this chain does not bound a polygon.

In graph theory, a 'cycle graph' is a graph (mathematics) that consists of a single path (graph theory), or in other words, some number of vertices connected in a closed chain.

Open chain exercises are postulated to be advantageous in rehabilitation settings because they can be easily manipulated to selectively target specific muscles, or specific heads of certain muscles, more effectively than their closed chain counterparts, at different phases of contraction.

The popliteus muscle in the leg is used for unlocking the knees during walking/standing by laterally rotating the femur on the tibia (or medially rotating the tibia) during a closed chain movement (such as one with the foot in contact with the ground).

A closed chain is called a cycle in a region if it is homologous to zero in the region; that is, the winding number, expressed by the integral of 1/(z a) over the closed chain, is zero for each point 'a' not in the region.
