1. Describe the differences in the following variables between a
trained (aerobically) and untrained individual: (1) SV response
during incremental exercise; (2) degree of oxygen deficit at the
beginning of submaximal aerobic exercise; (3) lactate threshold
relative to % VO2 max; (4) HR recovery post
exercise; and (5) resting HR.
2. What are the two adjustments the circulatory system
makes to help meet the increase O2 demand during exercise? Describe
each one in detail.
3. You are administering
an incremental exercise test for a subject. What
changes do you expect with respect to the following variables
(VO2, RER, blood lactate levels, predominant metabolic
system, and predominant fuel source) as the test goes on?
4. What are the two factors
of exercise that dictate the
predominant metabolic
system utilized during exercise? Explain how
an increase in each of these
two factors (separately) would shift the predominant type of
metabolism.
