What is trunk extension?
Trunk extension is achieved through the cooperative contraction of the hip extensors and trunk extensors Trunk extension exercises are often used in the physical training and rehabilitation of individuals with thoracic and lumbar spine pathologies, such as kyphosis, lordosis, and low back pain 6 , 16 , 17 ).
What muscles are used for good posture?
Several muscle groups, including the hamstrings and large back muscles , are critically important in maintaining our posture. These postural muscles, along with others, when functioning properly, prevent the forces of gravity from pushing us over forward.
What trunk muscle acts as an antagonist to the diaphragm?
The internal oblique performs two major functions. Firstly as an accessory muscle of respiration, it acts as an antagonist (opponent) to the diaphragm, helping to reduce the volume of the chest cavity during exhalation.
How effective are torso twists?
The Torso twist rotations assist in the body’s ability to do flexion, extension and multi-planar movements. Adding these movements into your training routine will assist in building strong abdominals and back muscles, therefore, improving all bodily movements, balance, and stability.
What is the purpose of trunk musculature?
Trunk muscles have a few very important functions; they contribute to the protection of the thoracic and abdominopelvic viscera and they assist essential body activities such as breathing, movement, defecation and micturition.
