Pulmonary
Where does gas exchange occur within the lungs?
Alveoli
Describe tidal volume.
Normal relaxed inspiration and expiration volumes
First group to ALL successfully pat their head and rub their tummy wins the points.
TOUGH ONE
Plyometrics
What percentage of oxygen is transported bound to hemoglobin?
98%
What percentage of atmospheric gas is composed of CO2?
0.03%
Why do aerobic athletes have lower resting heart rates?
Increased stroke volume leading to a lower HR to maintain cardiac output.
Draw AND explain the relationship between volume and intensity.
I'll draw it.
High volume (sets/reps) = low intensity (weight)
Low volume = high intensity
Describe the 2 pulmonary dangers of scuba diving.
Overexpansion injury: ascend without breathing out and lungs over expand
The bends: release nitrogen bubbles into the blood from ascending too quickly
What percentage of oxygen is extracted at the capillary during maximal exercise?
75%
Define afterload AND what occurs with a decreased afterload.
The pressure in the aorta that the heart has to pump against.
Decreased afterload = increased stroke volume
What exercise duration range would focus on the anerobic energy system?
30 sec - 2 minutes
Describe how pressure, volume, and the diaphragm changes during inspiration AND expiration.
Inspiration: Diaphragm contracts/descends, Pressure decreases, volume increases
Expiration: Diaphragm relaxes/ascends, Pressure increases, volume decreases
Draw the oxygen-hemoglobin dissociation curve AND label both axis
I'll draw it
What is the equation for mean arterial pressure (MAP)
MAP = CO x TPR
Choose any celebrity. Apply 3 of the principles of training to a single workout for them. Describe how they are used.
Specificity, Variation, Overload, Reversibility, Individuality
