PE - respiration

Question 1

immediate effects of exercise

Answer 1

*during exercise
- increased heart rate
- increased stroke vol
- increased body temp
- shortness in breath

Question 2

short term effects of exercise

Answer 2

*up to 36 hours after exercise
- tiredness / fatigue
- light-headedness
- naesea
- DOMS
- cramps

Question 3

long term effects of exercise - examples

Answer 3

*months / years of exercising
- body shape may change
- improved COF
- improve stamina
- increased stroke vol (more blood per beat)
- tolerance to lactic acid (delays fatigue)
- lower resting heart rate (bradycardia)
- increase in the size of the heart (hypertrophy)

Question 4

aerobic energy system - definition

Answer 4

uses oxygen to produce energy (ATP) for longer, sustained activities

Question 5

aerobic energy system - facts

Answer 5

• long, low intensity exercises
• requires continuous oxygen intake to maintain energy production
• endurance > intensity

Question 6

aerobic energy system - examples

Answer 6

• long-distance running
• steady-pace swimming
• long cycle rides
• waking
• dancing (endurance)

Question 7

aerobic respiration - formula

Answer 7

glucose + oxygen => carbon dioxide + water + energy

Question 8

anaerobic energy system - definition

Answer 8

produces energy without the need for oxygen

Question 9

anaerobic energy system - facts

Answer 9

• short, high intensity exercises
• buildup of lactic acid = fatigue & EPOC
• doesn’t required oxygen during activity
• max energy in short period of time

Question 10

anaerobic energy system - examples

Answer 10

• sprinting
• weightlifting
• jumping

Question 11

anaerobic respiration - formula

Answer 11

glucose => lactic acid + less energy

Question 12

EPOC - definition

Answer 12

• excess post-exercise oxygen consumption
• amount of oxygen your body needs right after exercise to return to its resting state
• also known oxygen debt

Question 13

EPOC - facts

Answer 13

• happens after every anaerobic exercise
• takes in extra oxygen
• to remove lactic acid
• to replace used energy
• slow heart rate / return body to rest

Question 14

factors affecting recovery - EPOC

Answer 14

• fitness levels
• intensity of exercise
• nutrition
• hydration
