Movement Flashcards
What is mechanical advantage?
Measures the efficiency of a lever
What is the resistance arm in mechanical advantage?
Distance between the load and the fulcrum
What is the effort arm in mechanical advantage?
Distance between effort and the fulcrum
How to calculate mechanical advantage?
Effort arm divided by resistance arm
What is a high mechanical advantage?
When the effort arm is longer then it’s load arm
What is a low mechanical advantage?
When the effort arm is shorter then its load arm
What is the first class lever?
When the fulcrum is in the middle
What is and second class lever?
When the load is in the middle
What is a third class lever?
When the effort is in the middle
What is the fulcrum?
A joint
What is the load? E.g as well
Bones or weights
E.g dumbbell
What is an effort? E.g aswell
Mostly muscles
E.g bicep
What does the Sagital plane allow?
Flexsion and extension
What does a transverse plane allow?
Rotation movements
What does a frontal plane allow?
Abduction and Adduction
