ana/aerobic exercise

Question 1

describe aerobic exercise

Answer 1

• uses oxygen for energy production
• includes activities that are of a long duration
• includes activities that are of a moderate intensity
• the heart and lungs can supply all the blood and oxygen to the working muscles to produce energy aerobically

Question 2

describe anaerobic exercise

Answer 2

• does not use oxygen for energy production
• includes activities that are if a short duration
• includes activities that are of a high intensity
• the heart and lungs cannot supply blood and oxygen to the muscles fast enough to use so energy is produced anaerobically

Question 3

give some sporting examples of aerobic exercise

Answer 3

• long distance cycling
• marathon running
• long distance rowing
• triathlon

Question 4

give some sporting examples of anaerobic exercise

Answer 4

• shot put
• sprinting
• long jump
• weight lifting

Question 5

what is the aerobic equation

Answer 5

glucose + o2 -> co2 + h2o + heat + energy

• glucose and oxygen combine to release energy aerobically
• this process produces carbon dioxide, water and heat (and energy)

Question 6

what is the anaerobic equation

Answer 6

glucose -> lactic acid + energy

• lactic acid is produced as a waste product when carbohydrates are broken down without oxygen during anaerobic respiration
• this causes muscles to become tired and work less efficient

Question 7

what does EPOC stand for

Answer 7

Excess Post-exercise Oxygen Consumption

Question 8

define EPOC

Answer 8

• the additional amount of oxygen consumed after anaerobic exercise
• referred to as oxygen debt

Question 9

what is EPOC

Answer 9

• refers to the amount of oxygen needed to recover after exercise
• enables lactic acid to be converted to glucose, carbon dioxide and water
• explains why we breathe deeply and quickly after vigorous exercise

Question 10

explain an EPOC graph

Answer 10

• three key parts: o2 deficit, resting requirements, EPOC
• the resting requirement identifies how much oxygen is required at rest
• when we start to exercise the demand for oxygen increases, it takes time to get the oxygen to the working muscles and not all the oxygen can be provided (anaerobic)- so there is an O2 deficit
• when we stop exercising the demand for oxygen remains higher (to pay back the deficit)- known as EPOC
