Functional Movement Flashcards
define functional biomechanics
applying the principles of mechanics to living organisms to understand the relationships and interactions that the various body parts, segments, and systems have with each other that contribute to the ability or inability to function
purposeful motor movements have 2 contradictory constraints
- to move one or several body segments toward a goal
- to stabilize other segments in order to maintain posture and equilibrium
what are the 6 risk factors for injury
previous injury
high/low BMI
asymmetry (muscle strength and flexibility/ROM)
poor dynamic neuromuscular control or balance
excessive muscle activation
dynamic lower extremity alignment
where are sensory receptors located and what do they do
located in muscles, tendons, ligaments, and joints
provide input to the CNS relative to tissue deformation
what do the visual and vestibular centers do
provide information about body position and balance
what is mechanoreceptors
the ability to sense body position
where are joint mechanoreceptors found
joint capsule, ligaments, menisci, muscles, tendons
where are muscle mechanoreceptors found
muscle spindles and golgi tendon organs
what is posture a gauge of
mechanical efficiency
kinesthetics sense
muscle balance
neuromuscular control
what is posture
body position that minimizes stress on the joints
describe performance posture
-there is significant demand placed on the back for sporting actions
-endless variety of active postures
-sometimes performance requires static posture
-sometimes performance requires dynamic posture
describe the ideal standing posture
the line of gravity bears a definite relation to certain anatomical landmarks when viewed from the side
-ear
-shoulder (acromion)
-hip (greater trochanter)
-knee (condyle)
-Ankle (malleolus)
should ALL be in a line
what is kyphosis
upperback curvature
what is lordosis
lower back curvature
what is scoliosis
S shape of the spine in the frontal plane
