Section 3 Flashcards
Define the core?
Th ability of your trunk to support the effort and forces from your limbs so that muscles and joints can perform in their optimum positions.
Name and describe 2 ligaments of the spine.
Antiror longitudinal ligament - connects each vertebral body together which runs anteriorly along front of spine, prevents excess extension of spine.
Posterior longitudinal ligament- runs along back of spine, prevents excess Flexion of spine.
What is meant by an accessory movement of the spine?
Movements that occur within a joint.
Name and describe one group of deep muscles within the spine.
Interspinalis- they attach between the processes of the spine to encourage extension of the spinal segments whilst also controlling smaller movements between vertebrae.
Describe function and attachments of the transversus abdominis muscle.
Wraps around body, attaches to lower ribs and pelvis, draws the waist in which compresses abdominal contents and increases intra-abdominal pressure to stabilise the spine.
What are the attachments of the multifidus muscle?
Connects the spinous processes of the spine to the transverse processes.
How does the diaphragm help to create intra-abdominal pressure?
Contracts downwards.
Identify two muscles responsible for the gross physiological movements of the spine.
Rotators and interspinalis
What factors can affect an individual’s posture?
Employment Lifestyle Habits Body weight Height Previous injuries
What commonly observed postures can be seen in people Who adopt long term seated positions?
Theoracic hyper kyphosis Protracted shoulders Shortened pecs Extended cervical spine Shortened upper trapezius Tilted pelvis Lumber Flexion
What commonly postural dysfunction might you see in someone performing a plank who is exhibiting core weakness?
Excess lumber extension
Severe thoracic Flexion
What are the general aims of static maintenance in comparison to static developments stretching?
Maintenance = maintains normal length of muscle
Developments = developed length of the fibres
Why is static stretching generally not used in a warm up?
Doesn’t prepare muscles for dynamic activity and does not decrease the incidents of injury.
Describe reciprocal inhibition and why is important within active stretching.
Where a stretch is held with no assistance other than using the agonist muscle which increase flexibility and strengthens the agonistic muscles.
When is it most appropriate to use dynamic stretching during an exercise session?
After some sort of pulse raising warm up.
