Biomechanics
Planes
-
Transverse plane - splits the body at the hip, an example being a pirouette
Frontal plane - Spilts the body in half sideways, example is side steps in Rugby
-
Axes
-
Tansverse is hip to hip, an example is a somersault
The joints in our bodies rotate around the different axes. These axes allow rotation to take place in one of the planes.
Longitudal is a vertical line from top to bottom, an example is a pirouette

First class lever
-
Examples
Rowing - Load = water, Fulcrum = Oar, Effort = Bicep
Rowing - Load = Weight, Fulcrum = Elbow, Effort = Tricep
Second class lever
-
Examples
Calf raises - Fulcrum = Ankle, Load = body + weights, Effort = Gastrocnemieus
Wheelbarrow - Fulcrum = Wheel, Load = dirt, Effort = Picking it up
Third class lever
-
Examples
Bicep curl - Fulcrum = Elbow, Effort = Bicep, Load = Weight
Kicking a ball - Fulcrum = knee, Effort = Quads, Load = ball
