Q

In the field of mechanics ( statics and dynamics) Dynamics is further subdivided into which two ?

Give an example of each also.

A

Kinematics & Kinetics

Kinematics – without reference to the forces acting on it.
Example: Air Squat – Planes and axes
Alignment of lower limb during the action
Angles created at: Ankle, Knee, Hip, etc

Kinetics – with reference to the forces acting on it. Example: Loaded Squat Bar weight, Internal & external force,  Internal forces generated by muscles External forces All ‘LINEAR’ motion in the body is a result of ANGULAR contributions. Example: In the loaded squat the bar moves in a straight line vertically as a result of angular motion of the joints.

Q

What are the 2 functions of a lever?

A

Levers have 2 functions

1: Mechanical advantage: overcoming a larger resistance than the force applied.
2. Speed: They increase the distance and the speed a resistance can be moved, through use of an effort greater than the resistance.

Q

Describe Body Slings (muscle slings or Myofascial slings) and what are the 4 separate units?

A

SENSORY INPUT: (Proprioception + Vision + Hearing)

39

A

“Muscles do not contract separately but work as functional groups, just as individual muscle fibres seldom contract independently”

45
Q

A

Agonist (prime mover & assistant movers)

46
Q

What is an antagonist ? Give an example

A

Antagonist (relax to allow movement)

Plantar flexors calf raise
Prime movers – Gastrocnemius, soleus and plantaris Assistant movers – Peroneus longus, peroneus brevis, tibialis posterior, flexor digitorum longus, flexor hallucis longus Antagonists – Tibilis anterior, EHL,EDL
47
Q

A

Muscles are considered synergists when they cooperate during execution of movement

  1. Stabilisers/ Fixators
  2. Neutralisers
    a. True
    b. Helping
  3. Force couples
48
Q

Explain a stabilising muscle with an example

A

Stabilisers / fixators: Press-ups – Abs contract isometrically

49
Q

Explain TRUE SYNERGY

A

True synergy- A muscle group that contracts to prevent the unwanted movement of a TWO JOINT MUSCLE.

50
Q

Explain HELPING SYNERGY with an example

A

Helping synergy – two muscles that share a common action and have their own second action antagonistic to that of the other.

Both contract simultaneously and act together to produce the desired common action.

Shoulder lateral DB raise.anterior deltoid “flex” posterior deltoids “Extend” the shoulder

By NETRALISING their independent actions they assist the medial deltoid with abduction of the shoulder to overcome resistance.

51
Q

Describe force couples

A

Force couples:

Producing force in the same direction or with the same intended movement.

Abdominals and glutes

Interaction of two or more muscles acting in different linear directions but producing a torque in the same direction

52
Q

Two joint muscles have two types of action, describe them

A

CONCURRENT ACTION: simultaneous extension or flexion of the hip and knee.

COUNTERCURRENT ACTION: shortens rapidly at both ends, losing tension. Hip flexion with knee extension.

53
Q

What is active insufficiency

A

Active insufficiency:

 Muscle that crosses Two or more joints simultaneously moves at all joints it reaches a length where can no longer create useful force.
54
Q

What is passive insufficiency

A

Passive insufficiency:
LIMITED BY THAT MUSCLES LENGTH rather than the arrangement of ligaments or structures of the joint.

MMA kick: Flexion of the hip, extension at the knee, but there is reduced hamstring length therefore PASSIVE INSUFFICIENCY.

Hamstrings are antagonists in Knee extension

55
Q

Lombards paradox is explain by what?

A

LOMBARDS Paradox

Standing from sitting, both agonists and antagonists are contracting but results in standing due to the true effort arm for extension is stronger than that of the effort arm for flexion.

56
Q

Mobility 《 - 》 Morbility

A

Functional Continuum

57
Q

At what range would you experience mechanical & physiological disadvantages?

A

Mechanical - outer

Physiological - Inner
