Movement analysis

Name the levers:
1st class (neck), 2nd class (ankle), 3rd class (elbow)
1 of 39
What are levers?
The function of a lever is to increase the speed of which a good can move at
2 of 39
Define fulcrum:
The joint itself
3 of 39
Define load:
Load=Weight=the object your trying to move
4 of 39
Define effort:
Muscle working
5 of 39
What does a first class lever increase?
Increases both effects of efforts and the speed of the body
6 of 39
What does a second lever increase?
Tend to increase the effects of the effort force
7 of 39
What does a third class lever increase?
Can be used to increase the speed of a body
8 of 39
List the order of the fulcrum, load and effort for a 1st class lever:
Effort, Fulcrum and Load (EFL)
9 of 39
Give an example of when using a first class lever:
Doing a header in football
10 of 39
What would the fulcrum, load and effort be for doing a header in football?
Fulcrum: neck joint, Load: ball, Effort: neck controlling
11 of 39
List the order of the fulcrum, load and effort for a 2nd class lever:
Effort, Load and Fulcrum (ELF)
12 of 39
Give an example of when using a second class lever:
When stationary on your tiptoes for reaching a smash in badminton
13 of 39
What would the fulcrum, load and effort be for when standing on your tiptoes for reaching a smash in badminton?
Fulcrum: toes, Load: weight of the body, Effort: gastrocnemius
14 of 39
List the order of the fulcrum, load and effort for a 3rd class lever:
Fulcrum, Effort and Load (FEL)
15 of 39
Give an example of when using a third class lever:
Bicep curl
16 of 39
What would the fulcrum, load and effort be for when doing a bicep curl?
Fulcrum: elbow, Load: bicep muscle, Effort: bicep muscle
17 of 39
Define a mechanical advantage:
Allow you to move a large output load with a smaller effort
18 of 39
What lever systems have a mechanical advantage?
First and second class
19 of 39
How do you work out a mechanical advantage?
Load/ Effort
20 of 39
What is lever 1 mainly for?
Doing something with your head
21 of 39
What is lever 2 for?
Only on balls on your foot e.g. defending in netball
22 of 39
What is level 3 for?
Arm when flexion and extending
23 of 39
What are the 3 planes?
Sagittal, Frontal and Transverse
24 of 39
What type of plane is the sagittal?
Vertical plane, dividing the body into right and left side (flexion& extension)
25 of 39
What type of plane is the Frontal?
Vertical plane, dividing the body into front and back (abduction& adduction)
26 of 39
What type of plane is the transverse?
Horizontal plane, dividing the body into upper and lower halves (rotation)
27 of 39
What is an axis?
Straight line around which an object rotates
28 of 39
What are the 3 axes?
Longitudinal, Transverse and Frontal
29 of 39
Describe the frontal axis?
Runs through the body horizontally from back to front
30 of 39
Describe the transverse axis?
Runs through the body horizontally from left to right
31 of 39
Describe the longitudinal axis?
Runs through the body vertically from the top
32 of 39
Give a practical example of a sagittal plane and a transverse axis:
Jogging in a straight line
33 of 39
Give a practical example of a sagittal plane and a transverse axis:
Forward role
34 of 39
Give a practical example of a frontal plane and a frontal axis:
Cartwheel
35 of 39
Give a practical example of a transverse plane and longitudinal axis:
Log roll in gymnastic
36 of 39
How can you tell if you are using the frontal axis?
You can only bend sideways
37 of 39
How can you tell if you are using the transverse axis?
You can only rotate e.g. pirouette
38 of 39
How can you tell if you are using the longitudinal axis?
Only bend backwards and forward
