study of biomechanics?
a) Physics; fluid mechanics and
thermodynamics (the study of energy)
b) Biology; understanding tendons and
muscles
c) Mathematics; calculus and algebra
d) Chemistry; the production of hormones
during exercise

Answer 1

D) Chemistry; the production of hormones
during exercise.

Question 2

Kinematics is the study of
human motion. True or False?

Answer 2

True.

Question 3

What are three of the biomechanical processes
that occur during a warm-up exercise?

Answer 3

Any three of these -1) Cardiorespiratory
changes (increased utilization of oxygen
by muscles); 2) increased blood flow
to active muscles; 3) increased body
temperature; 4) enhanced motor skills and
brain transmissions with nervous impulses
moving faster; and 5) increased discomfort
from muscles and cardiorespiratory system.

Question 4

What are the three groups of
proprioceptors?

Answer 4

1) Ligament, joint and skin proprioceptors;
2) neck and inner ear proprioceptors; and 3)
muscle proprioceptors.

Question 5

As you walk from one end of the room to
another, what forces are influencing your
movement?
a) Gravity
b) Friction
c) Tension
d) All of the above

Answer 5

D) All of the above.

Question 6

What is the opposite of the motion
pronation (to turn the palms face down)?

Answer 6

Supination.

Question 7

What are the three planes of motion that
intersect (meet at one point) in the body?

Answer 7

1) The sagittal plane; 2) the frontal plane;
and 3) the traverse plane.

Question 8

Concentric, eccentric and isometric/static are
the names of three major types of what?

Answer 8

Muscle action.

Question 9

How is muscle strength typically
measured?

Answer 9

The manual muscle test (MMT).

Question 10

What system of the body plays a role in
proprioception (perception of an object’s
position)?
a) Nervous system
b) Cardiorespiratory system
c) Immune system
d) Digestive system

Answer 10

A) Nervous system.
