SEMPER FIT BASIC FITNESS COURSE 2025-2026 EXAM ALL QUESTIONS
AND CORRECT ANSWERS (GRADED A+)
TERMS IN THIS SET (158) Q & A
>> Define exercise physiology
-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
-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?
-answer- Optimal fitness can be measured by accomplishing missions without undue fatigue.
>> The ability of a muscle to contract repeatedly without fatiguing.
-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.
-answer- Cardiopulmonary Endurance
, Page 2 of 35
>> Refers to the muscular and fat make-up of the body.
-answer- Body Composition
>> The ability to move your joints comfortably through a full range of motion.
-answer- Flexibility
>> The amount of force a muscle can produce.
-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.
-answer- Right; Left
>> Identify six adaptations of the heart and blood vessels in response to exercise.
-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.
, Page 3 of 35
(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.
-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?
-answer- adenosine tri-phosphate
>> Provides energy for endurance tasks
-answer- Aerobic
>> Provides energy for 30 to 90 seconds
-answer- Anaerobic
>> Provides energy for 6 to 10 seconds
-answer- Creatine Phosphate
, Page 4 of 35
>> Identify the three major benefits of warming up.
-answer- (1) Increases body temperature
(2) Improved range of motion
(3) Prepares the heart and lungs for higher intensity exercise
>> General Warm-up Method
-answer- Increases Temperature
Improves Flexibility
>> Passive Warm-up Method
-answer- Limited energy expenditure
>> Specific Warm-up Method
-answer- Increases temperature
Incorporates activity specific skills
Allows for mental rehearsal
Improves flexibility
