KNR 280 Illinois State University -Exercise Physiology
Exam III Questions | 2026/2027 | Answers Correct | With
Complete Solutions
VCO2 ____________ during exercise and ____________ at
maximal intensity
increases; increases sharply
ventilatory threshold
the point at which ventilation increases at a non-linear rate
difference between trained and untrained individuals
trained individuals will have a HIGHER Vt at rest and LOWER
Bf at rest
VE during maximal exercise
shifts upwards steeply
Vt dips and Bf increases to maintain VE
lungs take FASTER, but more shallow breaths after crossing
ventilatory threshold (no more available lung space)
VE ____________ with training
shows no change
resting O2 consumption does not adapt
resting Vt ____________ with training
, increases
resting Bf ____________ with training
decreases
ventilatory threshold ____________ with training
increases
at maximal intensity (VO2 max), VE, Vt, Bf, and a-VO2diff
____________
all increase in capacity
static lung volumes ____________ with training
do not increase
no change in size of lungs
EXCEPTION = swimmers and divers; larger static and dynamic
capacities to account for holding their breath for longer
heart
pumps blood
vasculature
conduit of blood vessels (arteries, capillaries, veins)
arteries
carry oxygenated blood away from the heart
veins
carry deoxygenated blood to the heart
