Chapter 3 Flashcards
Cardiorespiratory System
The term used to
describe the relationship between the
cardiovascular system (heart and blood
vessels) and respiratory system (lungs).
Calorie
A term used to describe food
energy. Scientifically, it is the amount of energy needed to raise one kilogram of water, 1 degree Celsius. More accurately, it is one kilocalorie.
Adenosine Triphosphate (ATP)
The basic unit of energy used by the cells.
Aerobic Energy System
The term used to describe the way cells produce ATP. In this case, the cells require oxygen to assist in ATP production.
Mitochondria
The area (organelle) of the
cell where ATP is produced.
Creatine Phosphate
a compound found in
the cells and used by the immediate energy
system that can be used to produce ATP.
Non-oxidative Energy System
a term used
to describe the way cells produce ATP. In
this case, cells do not require oxygen to
produce ATP.
Glucose
The simplest form of sugars found
in the blood.
Tidal Volume
The amount of air measured
during inspiration or expiration.
Diffusion Capacity
The amount of air that is
transferred from the lungs to the blood.
Areterial-vain difference (aVO2diff)
The
difference between the oxygen found in
arterial blood and venous blood.
Principle of Reversibility
The fitness
principle describing how fitness is lost while
detraining.
Maximal Energy Consumption (VO2max)
The maximum amount of oxygen the body
can take in and utilize.
Specificity
A fitness principle describing
how fitness improvements or adaptations
to exercise stress are specific to the type of
training that is performed.
Overload
The fitness principle describing
how adaption to exercise stress is driven by
progressively increasing the workload
during training.
