Metabolism & Energy Systems Training - Lecture 31

Question 1

What is Fatty Acid Oxidation?

Answer 1

Breaks down fat when it needs to be used as a fuel source to create ATP

Question 2

What are the fatty acids broken down into?

Answer 2

Acetyl-CoA

Question 3

How much ATP is produced in Fatty Acid Oxidation compared to Oxidative System

Answer 3

129 ATP instead of 34-36 ATP

Question 4

Why is there more ATP produced?

Answer 4

More Acetyl-CoA’s produced.

Question 5

Work to Rest Ratio

Answer 5

How much you work and how much you rest

Question 6

How are energy systems linked to Work:Rest Ratio?

Answer 6

Each energy system has its own Work:Rest Ratio

Question 7

SAID & Energy Systems

Answer 7

Specific Adaptations to Imposed Demands is related to improving energy systems. Must tailor the imposed demand to get a certain outcome

Question 8

How do we train ATP-CP System?

Answer 8

Short, fast/intense work periods (5-15 seconds)

Question 9

What’s the work to rest ratio for ATP-CP

Answer 9

1:12 or 1:20

Question 10

Why is the ratio for rest much higher

Answer 10

More prone to fatigue, so you need to rest to allow fuel to be replenished

Question 11

What are some adaptations seen with training ATP-CP?

Answer 11

Increase ATP and PcR storage, and target Type IIb fibres and increase in peak power.

Question 12

How would we train the glycolytic system?

Answer 12

Less rest; lower intensity but longer duration

Question 13

Work:Rest for Glycolytic System?

Answer 13

1:2 sometimes 1:3 or 1:5

Question 14

When do we have peak power output?

Answer 14

At the beginning of the exercise, and then it starts to decrease after seconds.

Question 15

What are some adaptations seen with Glycolytic?

Answer 15

Increase number and activity of anaerobic enzymes used, increase buffering capacity and anaerobic threshold shift. Targets Type IIa

Question 16

What fibres will be targeted with training glycolytic system?

Answer 16

Type IIa

Question 17

What is anaerobic threshold?

Answer 17

Certain point where blood lactate reaches a peak and then rapidly increases (caused by acidity)

Question 18

Metabolic Acidosis

Answer 18

Metabolic pathways create acidity in body through glycolysis.

Question 19

How to counter metabolic acidosis?

Answer 19

Respiratory compensation; Breathing out heavily allows to somewhat buffer the acidity.

Question 20

How would we train the oxidative system?

Answer 20

Least rest, lowest intensity but highest duration.

Question 21

Work:Rest for Oxidative

Answer 21

1:1 up to 1:3

Question 22

Which muscle fibres does oxidative target?

Answer 22

Type 1 fibres

Question 23

What adaptations are seen with training oxidative system

Answer 23

Cardiovascular and Muscular

Question 24

What adaptations of Cardiovascular

Answer 24

VO2 Max

Question 25

Adaptations of Muscular

Answer 25

• Increased # and activity of enzymes
• Increased # of capillaries in muscle
• Increased # of mitochondria
• Increased amount of glycogen in stores

Question 26

What adaptations take place with the fuel sources?

Answer 26

Body can rely more on fat stores during exercise before using carbs completely.
