Load
First class lever
Fulcrum in the middle
Eg. Attacking header, throwing a javelin
Second class lever
Load in the middle
Eg. Plantar Flexion
Adv: provides force to lift heavy load
Disadv: small range of moment and can’t move quickly
Due to load being close to fulcrum than effort
Third class lever
Effort in the middle
Eg. Bicep curl, kicking a football
Adv: speed and wide range of movement
Disadv: greater force required for load to be moved
Effort arm closer to fulcrum then load
