Chapter 6: Physiological Responses and Adaptations to Aerobic Endurance Training

Question 1

Respiratory Exchange Ratio (RER)

Answer 1

The ratio of the volume of carbon dioxide expired to the volume of oxygen consumed as measured at the mouth. (NSCA CPT, pg. 109)

Question 2

Frank-Starling Mechanism

Answer 2

The mechanism by which the stroke volume of the heart increases proportionally to the volume of blood filling the heart (the end-diastolic volume). NSCA CPT, pg. 108)

Question 3

Arteriovenous Oxygen Difference

Answer 3

The difference in the oxygen content of arterial blood versus venous blood expressed in milliliters of oxygen per 100 milliliters of blood. (NSCA CPT, pg. 110)

Question 4

Maximal Oxygen Uptake (Aerobic Capacity)

Answer 4

The highest capacity for oxygen consumption or utilization by the body during maximal physical exertion; also referred to as aerobic capacity, maximal aerobic power, maximal oxygen consumption, or VO2 max and sometimes functional capacity. (NSCA CPT, pg. 111)

Question 5

Overreaching

Answer 5

Short-term exercise training, without sufficient recuperation, that exceeds an individual’s capacity. (NSCA CPT, pg. 120)

Question 6

Fick Equation

Answer 6

Q = V. O2 ÷ a–v-O2 difference. (NSCA CPT, pg. 110)

Question 7

Blood Pressure

Answer 7

The force exerted by the blood on the vessels, driving blood through the circulatory system. (NSCA CPT, pg. 108)

Question 8

Factors that influence Adaptations to Aerobic Endurance Training

Answer 8

Specificity, Genetics, Sex, Age, (NSCA CPT, pg. 119)
