CH 8 (1-3)

Question 1

Bio-energetics:

Answer 1

ATP-PC (anaerobic metabolism) 0-30 seconds of work (power athletes, sprinters,
jumpers, Crossfitters, basketball, volleyball, body builders.)

Question 2

Glycolytic

Answer 2

30 sec – 3 min (middle distance 400m-800m)

Question 3

Oxidative

Answer 3

3-minutes (runners, cyclists, endurance athletes

Question 4

2-most important factors for bio-energetics:

Answer 4

Duration & Intensity

Question 5

Low intense =

Answer 5

fat (triglycerides; after 75+ min protein is deaminated)

Question 6

High Intense =

Answer 6

= carbs (glucose)

Question 7

TDEE:

Answer 7

Total Daily Energy Expenditure

Question 8

TDEE Formula =

Answer 8

(RMR x AF + TEF + NEAT)

Question 9

1.What is the name of the storage form of glucose?

Answer 9

Glycogen

Question 10

2. The formation of glucose from noncarbohydrate sources, such as amino acids is called:

Answer 10

Gluconeogenesis

Question 11

3. What is the proper order for oxidation of a free fatty acid?

Answer 11

Aerobic Glycolysis, Krebs Cycle, Electron Transport Train

Question 12

4. As activity increases, the usage of carbohydrate as an energy source becomes 50% and 50% fat, this metabolic marker is referred to as:

Answer 12

Ventilatory Threshold 1

Question 13

5. How many NON-ESSENTIAL Amino Acids are there?

Answer 13

11

Question 14

6. A 100m sprinter primarily uses ________________ as her energy source?

Answer 14

ATP-PC

Question 15

Adenosine Triphosphate

Answer 15

A high-energy molecule that serves as the main form of energy in the human body; known as the energy currency of the body.

Question 16

ATP-PC System

Answer 16

An energy system that provides energy very rapidly, for approximately 10–15 seconds, via anaerobic metabolism.

Generates energy very quickly for high-intensity, short-duration activities

Question 17

Glycolysis

Answer 17

Generates energy moderately quickly

Question 18

Oxidative System

Answer 18

Generates energy relatively slowly but for a long duration

Question 19

Ketosis

Answer 19

A state of carbohydrate depletion where the liver manufactures ketone bodies to meet energy demands that free fatty acid oxidation cannot support. Occurs when your body burns fat for energy instead of glucose.

Question 20

First Law of Thermodynamics

Answer 20

Energy cannot be created or destroyed but merely converted from one form to another.

Question 21

Excess Post Oxygen Consumption

Answer 21

The state in which the body’s metabolism is elevated after exercise.

Question 22

NEAT (Nonexercise activity thermogenesis/GREG)

Answer 22

Energy expenditure through daily activities outside of structured exercise, such as walking, completing household chores, and taking the stairs.

Question 23

TEF (Thermic Effect of Food)

Answer 23

The energy required to digest, absorb, and process nutrients that are consumed.

Question 24

Ventilatory Threshold 1

Answer 24

The point at which the body uses an equal mix of carbohydrate and fat as fuel sources.

As activity intensity increases, the usage of carbohydrate as an energy source becomes 50%, and the usage of fat becomes 50%.

Question 25

Ventilatory Threshold 2

Answer 25

The point where glucose provides nearly all of the energy for the activity.

The point where activity is so intense that glucose is providing virtually all of the energy for the activity, as fats metabolize too slowly to keep up with maximal demands.
