Chapter 17: Balance Training Concepts Flashcards
The approximate midpoint of the body; while the location may very between individuals, it is typically located at the midportion of the trunk
Center of gravity
The area beneath a person that consists of every point of contact made between the body and the support surface
Base of support
The area within which an individual can move one’s center of gravity without changing the base of support (i.e., moving the feet) without falling
Limits of stability
The ability to maintain the center of mass within the base of support in a stationary position, meaning no linear or angular movement
Static balance
The ability to maintain the center of mass with a stationary base of support yet allowing movement for the base supporting the body
Semi-dynamic balance
The ability to maintain a center of mass over an ever-changing base of support
Dynamic balance
Provides information about the position of the body and head, and spatial orientation relative to its surrounding environment; located in the inner ears that assist with balance
Vestibular system
Provides information that is acquired from receptors in the body (skin, muscle, joints, tendons) about the position and motion of the body parts relative to other body regions and the support surface
Somatosensory system
The interaction between the way the body processes visual, vestibular, and somatosensory information with the motor response of the body to that information
Sensorimotor function
The response (conscious or unconscious) of the muscles within the body to control purposeful movement
Neuromuscular control
A key ligament within the knee joint that provides stability to limit excessive motion of the tibia relative to the femur
Anterior cruciate ligament
A type of research article that synthesizes and summarizes findings from multiple existing research articles on a specific topic
Systematic review
An alteration of the body’s current state caused by the application of an external force
Perturbation
An unstable (yet controllable) exercise environment that causes the body to use its internal balance and stabilization mechanisms
Proprioceptively enriched environment
