SOC18 Aerobic, Anaerobic Exercise And Energy Sources

Question 1

Glucose

Answer 1

A major source of energy for most cells in the body

Question 2

What is aerobic respiration?

Answer 2

the process of releasing energy from glucose, using oxygen.

Question 3

What is anaerobic resoiration?

Answer 3

the process of releasing energy from glucose, without oxygen.

Question 4

What is aerobic exercise

Answer 4

working at a moderate intensity allowing the body time to utilise oxygen for energy production and to work for a continuous period, e.g. long-distance events.

Question 5

What is anaerobic exercise?

Answer 5

Working at a high intensity for short bursts in the range of 80-90% of your 1rm. Resukts in lactic acid

Question 6

What is lactic acid?

Answer 6

A colourless acid produced in muscle tissues during strenuous exercise when the body is exercising anaerobically at high intensity.

Question 7

What is a cramp?

Answer 7

painful, involuntary contraction of a muscle, usually caused by fatigue.

Question 8

What is oxygen debt?

Answer 8

The amount of oxygen needed at the end of exercise to oxidise any remaining lactic acid into co2 and water

Question 9

What are the main sources of energy?

Answer 9

Fats and carbohydrates

Question 10

What are carbohydrates?

Answer 10

Carbohydrates are the main energy source for both high-intensity (anaerobic) exercise and moderate-intensity (aerobic) exercise

Question 11

What are fats?

Answer 11

Fats can provide energy for only moderate-intensity (aerobic) exercise for long periods over 2 hours

Question 12

What are fats broken down into?

Answer 12

Fatty acids

Question 13

What do fatty acids do?

Answer 13

They get absorbed into your blood and delivered to cells and the remaining fatty acids are stored in fat cells

Question 14

What are carbohydrates broken down into?

Answer 14

Glucose or glycogen

Question 15

What happens when you eat carbohydrates?

Answer 15

• When you eat carbohydrates, they are broken down into glucose or glycogen, which can be absorbed through the walls of your small intestine and into the blood
• Glucose will pass into the blood, be transported to the liver and then circulated around the body
• Once your cells have used as much glucose as they need, some of the excess is stored in
the liver, ready to be distributed if your blood glucose levels get too low.
• The rest gets stored as fat

Question 16

What are complex carbohydrates for?

Answer 16

Foods of this type help to provide slow releasing and long lasting energy for exercise and should form about half of your daily intake

Question 17

What foods are complex carbohydrates found in?

Answer 17

Complex carbohydrates for example starch are found in natural foods such as brown rice, wholemeal bread and wholemeal pasta

Question 18

What are simple carbohydrates for?

Answer 18

They provide a quick fix of of energy. For example, eating a banana at half time of a football match

Question 19

Where are simple carbohydrates found in?

Answer 19

Simple carbohydrates are stored in their natural form in fruit and
vegetables, and in their refined form in biscuits, cakes and chocolates

Question 20

Define fats

Answer 20

A rich source of energy, but many modern day diets provide more than our bodies need

Question 21

Define carbohydrates

Answer 21

The body’s main source of energy
