2026 QUESTIONS AND ANSWERS | A+
GRADED | WITH EXPERT SOLUTIONS
Define exercise physiology - correct answer-Exercise physiology
is the science that describes, explains, and uses the body's
response and adaptation to exercise training to maximum human
physical potential.
It includes the interaction of the heart, lungs, and muscles, and
how they respond to exercise.
Define optimal fitness - correct answer-Optimal fitness refers to
the best functioning level of fitness a Marine can attain. At the
optimal level, the body of the Marine functions as efficiently as it
can.
Which factor measures a Marine's optimal fitness? - correct
answer-Optimal fitness can be measured by accomplishing
missions without undue fatigue.

The ability of a muscle to contract repeatedly without fatiguing. -
correct answer-Muscular Endurance
The ability of the heart and lungs to work efficiently over an
extended period of time and provide oxygen to the working
muscles. - correct answer-Cardiopulmonary Endurance
Refers to the muscular and fat make-up of the body. - correct
answer-Body Composition
The ability to move your joints comfortably through a full range of
motion. - correct answer-Flexibility
The amount of force a muscle can produce. - correct answer-
Muscular Strength
Blood is pumped to the lungs by the (blank) side of the heart and
pumped to the body by the (blank) side of the heart. - correct
answer-Right; Left

Identify six adaptations of the heart and blood vessels in response
to exercise. - correct answer-(1) The size of the heart increases
making it able to pump more blood with more force.
(2) The amount of blood the heart pumps with each contraction
increases. This is due to a combination of an increase in the heart
size and a decrease in pulse that allows more blood to enter the
heart between beats.
(3) There is a decrease in the resting and training heart rate.
(4) The heart rate recovers to resting levels more rapidly after
training has stopped.
(5) More capillaries form to supply the working muscles with
oxygen rich blood.
(6) Blood pressure decreases.
Cpl Jones participates in endurance training 3 times per week
while Cpl Jefferson participates once a week. What effect may
this have on both Marines' lungs. - correct answer-Cpl Jones'
body is effectively using a large amount of oxygen better than Cpl
Jefferson.

The molecule that provides the energy for muscle contraction is? -
correct answer-adenosine tri-phosphate
Provides energy for endurance tasks - correct answer-Aerobic
Provides energy for 30 to 90 seconds - correct answer-Anaerobic
Provides energy for 6 to 10 seconds - correct answer-Creatine
Phosphate
Identify the three major benefits of warming up. - correct answer-
(1) Increases body temperature
(2) Improved range of motion
(3) Prepares the heart and lungs for higher intensity exercise
