Levers
Lever system in the body
-
When we exercise, most of our moves involve lever
The lever system is made of 4 components, the first one is the load, the second one is the fulcrum, the third one is the effort and the final one is the lever
Explanation: "The load is the object requiring moving, the effort is the muscular force we use to move the object, the fulcrum is the joint around which the movement occurs and the bones of the skeleton are the levers."
Third Class lever
-
-
The first lever has in the middle fulcrum, the second lever has in the middle load and the third lever has in the middle the effort (lever 1-2-3 = F-L-E)
The third class lever has the most of examples in our body by being involved in lots of our movements
-
First Class lever
-
Example: "a fallen tree would use a first class lever system: the tree would be the load, the end of the wooden bar under the tree would be the fulcrum and the effort would be the muscular force applied to the other end of the wooden bar."

The mayor body axes
In order to bones move, a movement has to take place around the joint
In order to this movements take place, there has to be an axes that goes through the joint.
There are 3 main direction of axes that all movements rotate around. each axes act in different planes
-
Planes of motion
The body is split into 3 main planes, each plane involves a specific movement
