Misc. concepts for exam Flashcards
Saggital plane
R/L sides
Saggital plane motions
Adduction/abduction
Lateral flexion
Eversion/inversion
Ex. Side lateral raise, side lunge, side shuffle
Frontal plane
Front/back
Frontal plane motions
Flexion/Extension
Ex. Biceps curl, triceps pushdown, squat
Transverse plane
Top/bottom
Transverse plane motions
Rotation
Horizontal adduction/abduction
Ex. Throwing, golfing, swinging a bat, trunk rotation
Plantarflexion
extension at the ankle
Dorsiflexion
flexion at the ankle
Adduction
movement in the frontal plane toward the middle
Abduction
movement in the frontal plane away from the middle
Internal rotation
rotation toward the middle of the body
External rotation
rotation away from the middle of the body
The muscle action spectrum
Concentric, Eccentric, Isometric
Concentric
muscle shortens, “on the way out”
Eccentric
Muscle lengthens, “on the way back in”
Isometric
HOLD
Neuromuscular efficiency
ability to produce and reduce force and stabilize kinetic chain in all three planes of motion.
Davis’ law
soft tissue models along the lines of stress
Autogenic inhibition
neural impulses that sense tension are greater than the impulses that cause the muscles to contract; provides inhibitory effect to muscle spindles
Reciprocal inhibition
simultaneous contractor of one muscle and relaxation of its antagonist to allow movement.
Relative flexibility
tendency of the body to seek the path of least resistance
Altered reciprocal inhibition
muscle inhibition caused by a tight agonist, which inhibits its functional antagonist.
Synergistic dominance
inappropriate muscle takes over function of a weak or inhibited prime mover
Five phases of Optimum Performance Training (OPT) model
1) stabilization
2) strength endurance
3) hypertrophy
4) max strength
5) power
Proprioception
cumulative sensory input from al mechano receptors that sense position and limb movements
Macronutrients
Carbs
Fats
Protein
