Movement Analysis Flashcards
State the Three components of Any Lever System
Load/Effort, Resistance, Fulcrum/Pivot
Equation For Mechanical Advantage
Effort Arm/Resistance Arm
Joint action for a throw in (Football)
Extension
Main Agonist for a throw in (Football)
Triceps
Joint action at ankle for vertical Jump
Plantarflexion
What is Plantarflexion
Pointing Toes away from the body, e.g jumping
What is Dorsiflexion
Pointing Toes toward Shins.
Does the lever system operating at the ankle have a low or high mechanical advantage (2nd class)
The lever system has a high mechanical advantage due to effort being greater than resistance arm.
What bones is the shoulder joint made up of?
The humerus and the Scapula
Why can some Smaller people lift heavier weights than others when squatting?
As the resistance arm is longer in Taller people, meaning they can lift less heavy weights than shorter people whilst exerting the same force.
A third class lever system can move ________ with a ____ range of motion
A third class lever system can move Quickly with a large range of motion.
