PE Movement Analysis 1

levers in the body

bones

ligaments

muscles

lever functions

generate more force to move larger weights

produce greater range of movement

increases speed at which the body moves

where the lever system in the body is formed

wherever a muscle is attached to a bone

the muscles use the bones as levers against which they move to cause movement

fulcrum

the part that pivots

resistance/ load

load to be moved. weight

effort

force applied to move the resistance

mechanical advantage equation

MA= Effort arm / Resistance arm

3 types of axis

LONGITUDINAL: front to back. adduction and abduction

TRANSVERSE: left to right. flexion and extension
