Movement Analysis Flashcards
To learn the different types of movement
what are the lever systems
F ¦ 1
L/R ¦ 2
E ¦ 3
how do you calculate mechanical advantage
effort arm/resistance arm
what is the effort arm
the distance from the effort to the fulcrum
what is the resistance arm
the distance between the load/resistance to the fulcrum
which lever system always has a low mechanical advantage and why
3rd class because its lever arm is longer than its effort arm
which lever system always has a high mechanical advantage and why
2nd class because its effort arm is longer than its load arm. levers with high mechanical advantage can move heavy weights easily
what movements occurs at the shoulder, elbow, hip and knee
flexion or extension
what movement occurs at the shoulder
abduction or adduction
what movement occurs at the shoulder (360)
rotation
what movement occurs at the ankle
plantar flexion or dorsiflexion
what axis goes with the sagittal plane
Transverse axis (extension/flexion)
what axis goes with the Transverse plane
Longitudinal axis (rotation)
what axis goes with the frontal plane
Sagittal axis (abduction/adduction)
where is the Longitudinal axis
head to toe
where is the transverse axis
through the hips
