Movement Flashcards
Describe a first class lever system
Fulcrum lies between the effort and the resistance e.g. elbow joint
Describe a second class lever system
The fulcrum lies at one end with the effort at the other end and the resistance in the middle e.g. the ankle joint - set shot
Describe a third class lever system
The fulcrum lies at one end and the resistance is at the other end with the effort located between the fulcrum and the resistance e.g. elbow joint
Describe what is meant by mechanical advantage
The efficiency of a working lever, calculated by effort/weight (resistance) arm
Identify the three parts of a lever system
Load (resistance), fulcrum, effort
Identify three planes of the body
frontal, transverse, sagittal
Identify three axes of the body
sagittal, transverse, longitudinal
Describe sagittal axis
Through the belly button
Describe trasnverse axis
Through the hips
Describe longitudinal axis
Head to toe
Describe sagittal plane
Forwards and backwards
Describe frontal plane
Left or right
Describe transverse plane
Rotation along the longitudinal axis
