CHAPTER 3 - Bioenergetics

Question 1

What energy systems use Carbohydrates as their main energy source?

Answer 1

1. Anaerobic (glycolytic) System
2. Aerobic (glycolytic) System

Question 2

Name all FOUR energy Systems ranging from the highest ATP production rate to the lowest.

Answer 2

1. Highest - ATP-CP (Phosphagen) system
2. Anaerobic (Glycolytic) system
3. Aerobic (Glycolytic) system
4. Lowest - Fatty acid oxidation system

Question 3

What is Lactic Threshold?

Answer 3

The point where the body begins to form lactic acid, at which the body can no longer metabolize with oxygen present.

Felt like a burning sensation during exercise.

Question 4

What does EPOC stand for?

Answer 4

Excess Post-Exercise Oxygen Consumption

Question 5

Define and Explain Metabolism

Answer 5

Metabolism is the sum of all chemical reactions in the body, that is using or creating energy.

Question 6

What is Homeostasis?

Answer 6

The body’s way of saying it is in a state of balance and stability.

Question 7

Example Activities for the ATP-CP (Phosphagen) system?

Answer 7

50m-100m sprint, Golf, Tennis

Activities with short 1-10 sec bursts

Question 8

What is the most optimal relief option for the ATP-CP (Phosphagen) energy system?

Answer 8

It would be REST relief, due to the fact that ATP is being stored for the next working interval, in fact, if it were work relief that ATP being stored would be used for the relief, NOT the interval.

Question 9

Describe EPOC and its role in exercise recovery?

Answer 9

EPOC helps the body repay the oxygen debt created during the exercise session. After the workout is complete and the need for a higher supply of energy diminishes or ends, the body continues to take in extra oxygen to repay oxygen debt and begin cellular repair created by exercise. EPOC helps the body recover from both aerobic and anaerobic activities.

Question 10

Answer the following for the ATP-CP Energy System

1. ATP produced?
2. Time consideration? ex: 30-60 seconds
3. Type of energy?

Answer 10

1. 1 ATP Produced
2. 1-10 seconds
3. Immediate

Question 11

Answer the following for the Anerobic (Glycotic) system

1. ATP produced?
2. Time consideration? ex: 30-60 seconds
3. Type of energy?

Answer 11

1. 2 ATP / Glucose, 3 ATP / Glycogen
2. 10 seconds - 2 min
3. Short term

Question 12

Answer the following for the Aerobic (Glycolic) system

1. ATP produced?
2. Time consideration? ex: 30-60 seconds
3. Type of energy?

Answer 12

1. 38 ATP/glucose molecules
2. greater than 2 min
3. Long term energy

Question 13

Answer the following for the Fatty Acid Oxidation System

1. ATP produced?
2. Time consideration? ex: 30-60 seconds
3. Type of energy?

Answer 13

1. 100 ATP/ or fatty acid molecules
2. Greater than 2 min
3. Long term

Question 14

Explain the term Oxygen Deficit

Answer 14

A term used to describe when the body does not have the required oxygen for maintaining homeostasis during exercise.

Question 15

Should Aerobic Activities use Work or Rest relief?

Answer 15

Work

Question 16

What part of the cell does the Aerobic System utilize?

Answer 16

Mitochondrion

Question 17

What two systems require rest relief?

Answer 17

ATP-CP and Aerobic Glycolysis

Question 18

What is Lactic Acidosis?

Answer 18

W

Question 19
