Introduction to Health - Fit and Well 3

Olympic-caliber athletes may be able to increase their metabolic rate by
2000%.

Regular physical activity is linked to all of the following EXCEPT
lower endorphin levels.

In addition to pulse counting, one may also monitor exercise intensity by using
ratings of perceived exertion.

___________ supply oxygen-rich blood to the heart.
Coronary arteries

Fat is utilized as a fuel more efficiently during periods of
prolonged exercise.

The two upper chambers of the heart in which blood collects before passing it to the lower chambers are called
atria.

Adenosine triphosphate (ATP) is defined as
the basic form of energy used by cells.

Maximal oxygen consumption (VO2max) is
the best measure of the capacity of the cardiorespiratory system.

The nonoxidative energy system typically provides energy for
10–120 seconds.

The small blood vessels that connect the arteries and veins and distribute blood to all parts of the body are the
capillaries.

Excess loss of body fluid is called
dehydration.

The largest artery in the body is the
aorta.

During digestion, most carbohydrates are broken down into
glucose.

During systole, the heart is
contracting.

An appropriate exercise heart rate for an average individual is ________ of maximum heart rate.
75%

Recommended treatment of minor soft tissue injuries such as bruisesincludes all of the following EXCEPT
massage.

Alveoli serve what function in the lungs?
They allow for the exchange of carbon dioxide and oxygen.

If heat loss exceeds the body's ability to warm itself, ________ can result.
hypothermia

Systemic circulation carries blood to all organs of the body EXCEPT
the lungs.

As the result of regular endurance exercise, resting heart rate is often
10–20 beats per minute lower.

During the initial phase of an exercise program, a beginner should
exercise at the low end of the target heart rate range.

The oxidative energy system produces ATP in structures called
mitochondria.

Appropriate cardiorespiratory endurance exercise includes all of the following EXCEPT
push-ups.

To obtain a good endurance workout and boost cardiorespiratory fitness during low to moderate intensity activities such as walking or swimming slowly, the heart rate should be kept in the lower end of the target zone for
45 minutes, three times per week.

The portion of the circulation controlled by the right side of the heart is the ________ circulation.
pulmonary

The storage form of carbohydrate in the liver, muscles, and kidney is
glycogen.

An example of an activity that primarily uses the immediate energy system is
weight lifting.

Which of the following is NOT a component of the cardiorespiratory system?
the brain

Which of the following requires immediate medical attention?
heat stroke

A typical resting heart rate for a normal individual is around
60bpm.
