Title: Core stability
Passage: Core stability refers to a person's ability to stabilize their core.  Stability, in this context, should be considered as an ability to control the position and movement of the core.  Thus, if a person has greater core stability, they have a greater level of control over the position and movement of this area of their body.  The body's core is frequently involved in aiding other movements of the body, such as the limbs, and it is considered that by improving core stability a person's ability to perform these other movements may also be improved i.e. core stability training may help improve someone's running ability.  The bodies core region is sometimes referred to as the torso or the trunk, although there are some differences in the muscles identified as constituting them.  The major muscles involved in core stability include the pelvic floor muscles, transversus abdominis, multifidus, internal and external obliques, rectus abdominis, erector spinae (sacrospinalis) especially the longissimus thoracis, and the diaphragm.  The minor muscles involved include the latissimus dorsi, gluteus maximus, and trapezius.  Notably, breathing, including the action of the diaphragm, can significantly influence the posture and movement of the core; this is especially apparent in regard to extreme ranges of inhalation and exhalation.  On this basis, how a person is breathing may influence their ability to control their core.
