Q

What does the frontal axis look like?

A

One line through the middle do the body (at the hips)

24
Q

What movement does the frontal plane allow?

A

Adduction and abduction.

25
Q

What are the two types of isotonic contractions?

A

Eccentric and concentric

26
Q

What’s an eccentric contraction?

A

Muscle becomes longer.

27
Q

What’s a concentric contractions?

A

Muscle becomes shorter.

28
Q

What is an isometric contraction?

A

Without movement.
It’s static.
No change in muscle length.

29
Q

What are the hip flexes?

A

Cause Flexion at the hips.

30
Q

What’s the agonist?

A

Produces movement.

Muscle that contacts.

31
Q

What’s the antagonist?

A

The muscle that relaxes.

32
Q

What is the main agonist?

A

A type of muscle.

33
Q

Example of a isometric contraction?

A

The plank or deep hold of a squat.

34
Q

Example of an eccentric movement?

A

Lowering of a push up- elbow.

35
Q

Example of a concentric contraction?

A

Standing up in a squat- hip.

36
Q

What is a lever?

A

Rigid bar floating around a fixed point.

37
Q

What are the parts of a lever?

A

Effort (E), Fulcrum (F) and Load (L) / Resistance (R)

38
Q

What parts of the body make up the lever system?

A

Rigid bar- bone
Fulcrum- joint
Effort- muscle
Resistance- what your carrying.

39
Q

What are the two functions of a lever system?

A
  1. Increase the resistance that a given effort can move.

2. Increase the speed at which a body moves.

40
Q

Describe a first class lever system.

A

R F E

Fulcrum lies between the effort and the resistance

41
Q

Example of a first class lever system?

A

Elbow (tricep)

42
Q

Advantage of the 1st class lever system?

A

Increase the effects of the effort and speed of the body.

43
Q

Describe a second class lever system.

A

F R E

Resistance lies between the fulcrum and effort.

44
Q

Example of a second class lever system?

A

Ankle.

45
Q

What’s the advantage of a second class lever system?

A

Increase the effect of the effort force.

46
Q

Describe a third class lever system.

A

F E R

Effort lies between the resistance and the fulcrum.

47
Q

Example of a third class lever system?

A

Forearm Flexion.

48
Q

Advantage of a third class lever system?

A

Increases the speed of the body.

49
Q

What does mechanical advantage mean?

A

If the mechanical advantage is less that 1- increase the speed of movement.

If the mechanical advantage is more than 1- increase in effect of force.

50
Q

What does MA mean?

A

Relative efficiency of the lever system.

51
Q

What’s the MA sum?

A

MA= Effort arm divided by Resistance arm.

52
Q

What is the effort arm?

A

The distance between the fulcrum and the effort.

53
Q

What is the resistance arm?

A

The distance between the fulcrum and the resistance.

54
Q

Longer the effort arm………

A

The less effort required to move a given resistance.

55
Q

How to remember the lever systems?

A

FRE

(what’s in the middle of the system)

F- fulcrum
R- resistance
E- effort

56
Q

Adduction and……

A

Abduction
