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.
