Chapter 6-Physiological Responses And Adaptations To Aerobic Endurance Training

Question 0

What role does glucagon play in aerobic metabolism?

Answer 0

Stimulates increase in plasma glucose concentration.

Question 1

At what percent of VO2 Max is stroke volume maximized?

Answer 1

40-60%

Question 2

Does insulin increase or decrease during aerobic exercise?

Answer 2

Decrease

Question 3

What role does cortisol play in aerobic metabolism?

Answer 3

Promotes use of fats as it helps maintain normal blood sugars.

Question 4

What are catecholamines and what is their role in aerobic metabolism?

Answer 4

Epinephrine and norepinephrine, the fight or flight hormones.

Help deliver blood and oxygen to muscles as they elevate the heart rate and blood pressure.

Question 5

List some long term adaptations to aerobic exercise

Answer 5

Increased stroke volume

Decreased blood pressure

Increased capillary density

Ventilatory efficiency improves

Question 6

Changes in skeletal muscle that enhance endurance performance include:

Answer 6

Increased capillary supply
increased mitochondrial density
enhancement of oxidative enzymes
increased intramuscular glycogen 
Increased muscle myoglobin stores

Question 7

Define overreaching

Answer 7

Short term training, without sufficient recovery, that exceeds individual capacity

Question 8

What are the two types of overtraining?

Answer 8

Aerobic endurance overtraining=parasympathetic dominance

Anaerobic or resistance overtraining =sympathetic dominance
