Lesson 16: Functional Movement and Resistance Training Flashcards
What is joint stability defined as?
The ability to maintain or control joint movement or position.
How is joint stability achieved?
Through the synergistic actions of the joint’s components aka muscles, ligaments, joint capsules and the neuromuscular systems.
What is joint mobility defined as?
The range of uninhibited movement around a joint or body segment.
How is joint mobility achieved?
Through the synergistic actions of the components of the joint and neuromuscular system.
Movement efficiency involves a synergistic approach between stability and mobility, how does this work?
proximal stability promotes distal mobility
Does the glenohumeral joint promote mobility or stability?
mobility
Does the scapulathoracic region promote mobility or stability?
Stability
Does the thoracic spine promote mobility or stability?
Mobility
Does the lumbar spine promote mobility or stability?
Stability
Does the hip promote mobility or stability?
Mobility
Does the knee promote mobility or stability?
Stability
Does the ankle promote mobility or stability?
Mobility
Does the foot promote mobility or stability?
Stability
What will occur when mobility is compromised?
The joint will seek to achieve full ROM by involving movement into another plane and/or certain stable joints may look to compromise stability in order to reach the desired level of mobility.
If the hip flexors lack flexibility in a bird dog movement, what is likely to occur due to compromised mobility?
The extended leg and hip will likely rotate in to the transverse plane.
If a client with kyphosis tries to extend the thoracic spine, what is likely to occur as a result of compensation for the lack of thoracic mobility?
An increase in lumbar lordosis
True or false, muscle imbalances do not alter the physiological and neurological properties of muscles?
False
True or false, muscle imbalance contributes to dysfunctional movement?
True
How do technological advancements such as exercise machines raise a potential concern for mobility and stability training?
Often, individuals with limited stability/mobility will use the machines for compensated movement, yet, this does not fix the original issue.
What are the 6 stages of dysfunctional movement?
- Muscle imbalance
- The muscle imbalance alters physiological and neurological properties
- The mobility-stability relationship is compromised
- The body learns to achieve the desired movement with least resistance
- Dysfunctional movement occurs
- There is an inevitable breakdown of the body
Why does periods of inactivity (ie sedentary) lead to muscle imbalances and therefore physiological and neurological property issues?
During periods of inactivity, joints are held in shortened position causing certain muscles to shorten and their antagonist muscles to lengthen.
What is the length-tension relationship between?
The length-tension relationship is between the contractile proteins of a sarcomere and their force generating capacity.
What are two examples of contractile proteins?
Actin, myosin
What does a slight stretch of the sarcomere beyond its normal resting length result in?
This increases the spatial arrangement between the muscle’s contractile proteins and increases the force generating capacity - AKA this is length-tension relationship.
