FOUNDATIONAL CONCEPTS Worksheet

bending movement; decreases relative angle between segments
straightening movement; increase relative angle between segments
extension at the ankle
flexion at the ankle
movement away from the middle
movement toward the middle
transverse plane arm movement from anterior to lateral (ie. chest flies)
rotation toward the mid line
rotation away from the midline
muscular force greater than resistive force; muscle shortens
muscle developes tension while lengthening; decelerates force
muscular force equal to resistive force; no change in muscle length
resting length of a muscle and the tension it can produce at that length
muscles working together to produce movement
as the veloctiy of a contraction increases, concentric force decreases and eccentric force increases
ability to produce and reduce force, and stabilize the kinetic chain in all three planes of motion
alingment of the musculoskeletal system that allows center of gravity to be maintained over a base of support
soft tissue modles along the lines of stress
when neural impulses that sense tension are greater than the impulses that cause muscles to contract; inhibits muscle spindles
simultaneous contraction of one muscle, and relaxation of its antagonist to allow movement
tendency of the body to seek the path of least resistance
consistently repeating the same motion; places abnormal stresses on the body
predictable patterns of muscle imbalances
muscle inhibition caused by a tight agonist, which inhibits its functional antagonist
synergist takes over function for a weak or inhibited prime mover
alteration of muscle length surrounding a joint
