Flashcards in Chapter 4 Deck (26):
1

Study of how energy is transferred into usable forms in the human body through different chemical reactions

Bioenergetics

2

Process of which nutrients are acquired, transported, used, and disposed of by the body.

Metabolism

3

What are the 3 substrates

Carbs, proteins, fats

4

What happens to Carbs once ingested

Broken down into Glucose and enters our cells. They are then stored as glycogen in the liver and muscle cells however, there is a limited ability to store carbs

5

Chemical form of fat found in the body

triglycerides

6

When is fat used for energy

prolonged periods of exercise (marathon), low intensity, and rest

7

What substrate does not provide energy during exercise

Protein

8

The only time protein would be used as energy would be

Starvation. Gluconeogenesis- protein converts to glucose

9

Name the two anaerobic energy systems

ATP-PC and Glycosis

10

When would you use the ATP-PC system

High intensity short duration exercise such as a sprint

11

How long does ATP-PC last

10-15 seconds

12

What is the first system used at onset of all exercises

ATP-PC

13

How long does Glycolysis last, when would we use it

30-50 second; most fitness workouts in the 08-12 reps(phase 2)

14

What is the Aerobic Energy system and its components

OXIDATIVE SYSTEM
Aerobic glycolysis
Krebs
ETC

15

When is the Oxidative system used?

Transitioning to sustained exercise, rest. Produced energy for indefinite periods of time. (marathon)

16

What is the Oxidative systems main source of fuel?

Fat

17

State of increased metabolism after performing anaerobic exercise

EPOC (Excessive postexercise oxygen consumption)

18

How is anaerobic debt repaid in regards to EPOC

Anaerobic exercise is repaid by increasing o2 use after exercise. More calories are used many hours after we work ou

19

Explain the myth of the fat burning zone

Myth: burn more fat at lower intensity
This is not true. Sleep uses fat but doesn't burn many calories at all. A higher intensity burns more caloies. The % from fat is less but the total amount of fat used is greater. More calories burned= more fat lost.

20

Examination of bioenergetics as it relates to the unique physiologic changes and demands placed on the body during exercise

Exercise metabolism

21

Material or substance on which enzymes act

Substrates

22

Rq in which fat is 100%

.7

23

RQ in which carbs are 100%

1.0

24

Energy storage and transfer unit within the cells of the body

Adenosine Triphosphate

25

High energy compound occuring in all cells from which atp is formed

Adensosine Diphosphate

26

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

Excess post exercise oxygen consumption
