Q

How would you describe a cartwheel in terms of planes and axis?

17
Q

How would you describe a 360 spin in terms of axis and planes?

A

in a transverse plane about a longitudinal axis

18
Q

What is a lever?

A

a solid bar that moves about a fixed point when force is applied to it.

19
Q

How does the body use levers?

A

When a muscle pulls on a bone to move a part of the body about a joint

20
Q

What is the lever arm?

A

the bone or body part being moved about a point

21
Q

What is the effort?

A

the force applied by the muscles to the leaver.

It is represented by a arrow pointing in the direction of the force.

22
Q

What is the fulcrum?

A

The joint where the lever arm pivots. It is shown by a triangle

23
Q

What is the load?

A

the resistance against thepull of the muscles on the lever arm. a sqaure is used to represent the load.

24
Q

What is a 1st class lever system?

A

The load and effort are at opposite ends of the lever. the fulcrum is in the middle. Tilting your head back is a first class lever. EFL

25
Q

what is a 2nd class lever system?

A

The fulcrum and effort are at topposite ends of the lever. The load is in the middle. Standing on your toes uses a second class lever system. FLE

26
Q

What is a 3rd class lever system?

A

The fulcrum and load are at opposite ends of the lever . the effort is in the middle. Flexion at the elbow uses a third class lever system. FEL

27
Q

What is the acronym used to remeber the three lever systems?

A

EFL the FLE FEL

28
Q

What is a mechanical advantage?

A

When a lever can move a large load with a small effort from the muscles. (only moves small distances slowly)

29
Q

When does a lever have a mechanical?

A

when the distance from the fulcrum to the effort is greater than the distance from the fulcrum to the load.

30
Q

What classes always have mechanical advantage?

A

2nd class lever and some times the first class

31
Q

How do u calculate mechanical advantage

A

Effort arm/resistance

32
Q

What is concentric and escentric muscle contraction

A

Concentric: muscle which lengthens
Eccentric: muscle which shortens
Check

33
Q

How do you calculate mechanical advantage?

A

effort arm/resistance arm
