8
Q

Why is aerobic respiration more efficient than anaerobic (2)

A
  • more energy can be produced

- less harmful by-products

15
Q

What does EPOC do

A
  • replenishes body with oxygen

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

16
Q

Methods of recovery (4)

A
  • cool down
  • manipulating diet
  • ice baths
  • massage
17
Q

Why is a cool down good

A
  • Reducing intensity helps maintain elevated heart/breathing rate
  • Ensures blood continues to flow quickly to muscles
18
Q

What does a cool down do to lactic acid

A

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

19
Q

Why is drinking water good

A

Replace lost fluids

20
Q

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

A
  • intensity
  • duration
  • humidity
  • temperature
  • altitude
  • body composition
21
Q

What is carbohydrate loading

A

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

22
Q

How does hypertrophy happen

A

When small tears in muscle (from training) repair

23
Q

What needs to be consumed for hypertrophy to happen

A

Protein

24
Q

What does DOMS stand for

A

Delayed Onset Muscle Soreness

25
Q

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

A

DOMS

26
Q

What is DOMS

A

The pain felt in muscles the day after exercise

27
Q

What does a massage do

A

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

28
Q

What do ice baths do

A

Hell the body flush lactic acid from muscles

29
Q

How do ice baths work

A
  • The cold causes vasoconstriction, forcing lactic acid out

- Getting out the bath into the warm, blood vessels dilate and bring oxygenated blood in

30
Q

Anaerobic % heart rate

A

80-90%

31
Q

Aerobic zone % heart rate

A

70-80%
