Core Stability Exercise Principles
Current Sports Medicine Reports, 2008Core stability is essential for proper load balance within the spine, pelvis, and kinetic chain. The so-called core is the group of trunk muscles that surround the spine and abdominal viscera. Abdominal, gluteal, hip girdle, paraspinal, and other muscles work in concert to provide spinal stability.

Stability and largeness of core for symmetric games [PDF]
International Journal of Game Theory, 2000 Shapley showed the necessary and sufficient condition for the core to be the stable set. The main result of this paper is an alternative proof of this result.

Core and Lumbopelvic Stabilization in Runners
Physical Medicine and Rehabilitation Clinics of North America, 2016Core muscles provide stability that allows generation of force and motion in the lower extremities, as well as distributing impact forces and allowing controlled and efficient body movements. Imbalances or deficiencies in the core muscles can result in increased fatigue, decreased endurance, and injury in runners.

2007
In this paper, we study the problem of core stability for flow games, introduced by Kalai and Zemel (1982), which arises from the profit distribution problem related to the maximum flow in networks. Based on the characterization of dummy arc (i.e., the arc which satisfies that deleting it does not change the value of maximum flow in the network), we ...

Optimizing Performance by Improving Core Stability and Core Strength
Sports Medicine, 2008Core stability and core strength have been subject to research since the early 1980s. Research has highlighted benefits of training these processes for people with back pain and for carrying out everyday activities. However, less research has been performed on the benefits of core training for elite athletes and how this training should be carried out ...

Stability of core–shell magnetite nanoparticles
Colloids and Surfaces B: Biointerfaces, 2014In the paper, we present three different types of magnetite nanoparticles which were prepared from co-percipitation of iron (II) and (III) chlorides in aqueous solution with and without SiO2 and from thermal decomposition of iron (III) acetylacetonate in nonaqeous solutions.

On core stability, vital coalitions, and extendability
Games and Economic Behavior, 2009Let \((N,v)\) be a TU game in coalition function form. The main result of the paper is a sufficient condition for \((N, v)\) to have a stable core: vital coalitions and exact coalitions are extendable. Also, vital-exact extendability is a necessary condition for core stability for matching games, simple flow games, and minimum coloring games.

Finite-core hetons: stability and interactions
Journal of Fluid Mechanics, 2000The dynamics of vertically compensated two-layer vortices (hetons) with finite cores are examined within the context of the quasi-geostrophic approximation on the f-plane. The two-layer version of the contour dynamics method is used, and complemented by the so-called contour surgery technique.
