Performance
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
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.
(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
Identify the three major benefits of warming up. - ANSWER-(1) Increases body
temperature
