Ch 17 Flashcards
Interaction between the body’s processing of info (visual, vestibular, somatosensory) and the body’s motor repones to that info
Sensorimotor function
Alteration of the body’s current state cause by the application of an external force
Perturbation
Unstable yet controllable exercise environment that causes the body to us it’s internal balance and stabilization mechanisms
Proprioceptively enriched environment
Main goal of balance training
Continually increase the clients awareness of their limit of stability
What are the exercises included in the last progression of balance training designed to do?
Develop proper deceleration ability to move the body from a dynamic state to a controlled stationary position
When performing the single leg hip rotation what will help decrease stress to the spine and enhance control of the core?
Rotate through the hip of the balance leg rather than the spine
Which balanace training exercise is part of the second stage of balance training that uses dynamic, eccentric and concentric movement of the balance leg through full ROM?
Single leg squat
Area within which an individual can move their center of gravity without changing the base of support
Limits of stability of the body
What type of balance occurs when an individual seeks to maintain the center of mass over an ever changing limit of stability?
Dynamic balanace
Motor functions of muscle in the lower extremity?
Neuromuscular function
What kind of balance is a hop training program on a firm surface?
Semi dynamic balance
What balance task requires significant use of vestibular system?
Squatting on one limb w eyes closed
The addition of balance training to a strength if program enhances what?
Somatosenation
To move efficiently, forces must be dampened (eccentrically), stabilized (isometrically) and then accelerated (concentrically)
Integrated performance paradigm
Ability to change direction without falling while moving on unstable surface
Dynamic balance
Single leg throw and catch is what kind of balance stabilization exercise
Balance stabilization
What kind of balance exercise is single leg hip rotation?
Single leg hip rotation
Is intensity an acute variable for balance stabilization training?
Intensity
Which training levels use total body exercises?
Stabilization level, strength level and power level
How does balance training develop neuromuscular efficiency
By simulating unstable yet controllable enviornments
Ability of muscles to exert max force output in a minimal amount of time
Rate of force production
Elastic energy stored; stimulation of muscle spindles; signal to spinal cord
Eccentric
Nerve meet synapse in spinal cord; signal sent to stretched muscle
Amortization
Elastic energy released; enhanced muscle force production
Concentric
