QUESTIONS AND CORRECT ANSWERS
ALREADY PASSED GRADED A+
◉ What is the connection between agonist and antagonist? Answer:
As the agonist contracts, the antagonist relaxes
◉ What does stabilizer muscle mean and give an example of its use
in an exercise? Answer: Muscles that stabilize the body or body parts
through multi-plane movements
◉ What is synergy in correlation to muscles? Answer: Synergy is
performed by a synergist muscle which provides joint stability for
effective agonist action.
◉ Name and describe the 4 types of muscular movement Answer:
Isometric: muscle length remains constant and maintains tension
Isotonic: muscle length changes and maintains tension
Concentric: muscle length decreases in resistance to force
,Eccentric: muscle length increases and is overcome by force
◉ Describe the 3 imaginary planes of motion and give an exercise
executable in each Answer: Sagittal: passes to and from the front and
back
Frontal: divides front and back
Transverse: divides top from bottom.
◉ Biomechanics Answer: The scientific system of movement as it
relates to musculoskeletal action.
◉ Describe the fundamental principles of stability Answer: Stability
is the ability to maintain a balanced state and control the body
through movement as desired
The larger the base of support, the greater the stability
The lower the centre of mass/gravity, the greater the stability
◉ What is the correct foot position and weight assignment during
these exercises: Answer: Back squat: Shoulder width apart
,Bench press: feet under hips, weight on the forefoot
◉ Name and describe the 4 elements of force Answer: Magnitude:
the amount of force applied
Direction: the trajectory of application from start to end
Point of application: the area where force is applied
Line of action: the path from application that indicates the direction
of force.
◉ Describe Newton's first law of motion Answer: A physical object's
state of motion or motionlessness remains constant unless an
external force is applied (inertia)
◉ Describe the difference between resting and moving inertia?
Answer: Resting inertia is a resting objects resistance to change
unless influenced by force. moving inertia is a moving objects
resistance towards changing speed and direction unless influenced
by force.
◉ Describe what is meant by range of motion. What is its
significance? Answer: The capacity of movement about a joint from
, full flexion to full extension. ROM determines flexibility and optimal
technique
◉ Describe Newton's second law of motion as it relates to mass and
acceleration Answer: Force is produced by accelerating a mass
through a change in velocity
◉ Explain "work" and how it is applied in an exercise Answer: The
amount of force over a given distance
◉ Define "power" and how it is used in a weight training exercise
Answer: The amount of force over a given period of time
◉ Describe Newton's third law of motion Answer: For every action,
there is an equal and opposite reaction
◉ Describe a lever in relation to the body Answer: A lever is a bone
that turns about the rotational axis of a joint
◉ First class lever Answer: Fulcrum is placed at the centre of the
lever making each end equidistant. force and load are placed at
opposite ends. e.g. the head and top of c-spine
