There are numerous muscles that make up the core, the deeper stability muscles (transverse abdominis, multifidus and the pelvic floor muscles) and the larger global muscles
(obliques, rectus abdominis and gluteus maximus),' says Holly.
18) Another study reported the increased activation of local and global muscles
during the stabilization exercise on unstable surfaces.
In particular, this exercise is reported to minimize the use of global muscles without pain while activating local muscles (Saliba et al.
Trunk muscles are traditionally classified into global muscles (namely, the RA, ES, and EO muscles) and local muscles (namely, the IO, MF, and transverse abdominis muscles) by function (Stevens et al.
2011) reported that application of the sling exercise is a close kinematic chain exercise method that contributes to balance improvement because it uses local and global muscles, findings that are similar to our results on the %MVIC values of the MF muscle.
O'Sullivan explains that your core is composed of local and global muscles.
The global muscles include the hip muscles, such as the paoas and gluteals, and the other abdominal muscles, such as the rectus abdominis and internal and external obliques.
16) These muscles can be loosely referred to as the global muscles of the spine.
56) However, the automatic activation of the local muscles is not improved (at least in the short term) by common stability exercises involving co-contraction of the global muscles, such as "side-bridging," curl-ups, or "bird-dog.
In addition, during activity involving directional movement or increased loading there should be a greater contribution from the global muscles.
