Aerobic And Anaerobic Exercise 1.4

Question 1

Aerobic respiration equation

Answer 1

Glucose + oxygen -> energy + carbon dioxide + water

Question 2

Glucose + oxygen -> energy + carbon dioxide + water

Answer 2

Aerobic respiration equation

Question 3

Anaerobic respiration equation

Answer 3

Glucose -> lactic acid + energy

Question 4

Glucose -> lactic acid + energy

Answer 4

Anaerobic respiration

Question 5

Aerobic respiration definition (3)

Answer 5

• presence of oxygen
• long period of time
• steady

Question 6

Anaerobic respiration equation (3)

Answer 6

• short period of time
• high intensity
• absence of oxygen

Question 7

Is aerobic or anaerobic respiration more efficient

Answer 7

Aerobic

Question 8

Why is aerobic respiration more efficient than anaerobic (2)

Answer 8

• more energy can be produced

- less harmful by-products

Question 9

Intensity definition

Answer 9

Amount of energy needed to complete activity

Question 10

Amount of energy needed to complete activity

Answer 10

Intensity

Question 11

What is lactic acid

Answer 11

Mild poison and waste product of anaerobic respiration

Question 12

Mild poison and waste product of anaerobic respiration

Answer 12

Lactic acid

Question 13

What does EPOC stand for

Answer 13

Excess Post-exercise Oxygen Consumption

Question 14

What is EPOC

Answer 14

The amount of oxygen needed to recover after anaerobic exercise

Question 15

What does EPOC do

Answer 15

• replenishes body with oxygen

- enables body to convert lactic acid to glucose, carbon dioxide and water

Question 16

Methods of recovery (4)

Answer 16

• cool down
• manipulating diet
• ice baths
• massage

Question 17

Why is a cool down good

Answer 17

• Reducing intensity helps maintain elevated heart/breathing rate
• Ensures blood continues to flow quickly to muscles

Question 18

What does a cool down do to lactic acid

Answer 18

Replenishing body with oxygen helps it convert lactic acid into glucose, carbon dioxide and water (prevents DOMS)

Question 19

Why is drinking water good

Answer 19

Replace lost fluids

Question 20

What determines how much water you need to drink after exercise (6)

Answer 20

• intensity
• duration
• humidity
• temperature
• altitude
• body composition

Question 21

What is carbohydrate loading

Answer 21

Increasing amount of complex carbohydrates eaten days before an event to maximise glucose

Question 22

How does hypertrophy happen

Answer 22

When small tears in muscle (from training) repair

Question 23

What needs to be consumed for hypertrophy to happen

Answer 23

Protein

Question 24

What does DOMS stand for

Answer 24

Delayed Onset Muscle Soreness

Question 25

What is the pain in muscles you feel the day after exercise

Answer 25

DOMS

Question 26

What is DOMS

Answer 26

The pain felt in muscles the day after exercise

Question 27

What does a massage do

Answer 27

Increases blood flow to the sore area, speeding up healing process (more oxygen)

Question 28

What do ice baths do

Answer 28

Hell the body flush lactic acid from muscles

Question 29

How do ice baths work

Answer 29

- The cold causes vasoconstriction, forcing lactic acid out | - Getting out the bath into the warm, blood vessels dilate and bring oxygenated blood in

Question 30

Anaerobic % heart rate

Answer 30

80-90%

Question 31

Aerobic zone % heart rate

Answer 31

70-80%
