Question 1

What is the formula for Aerobic Respiration?

Answer 1

Glucose + Oxygen -> Carbon dioxide + water + energy

Question 2

What is the formula for Anaerobic respiration?

Answer 2

Glucose -> energy + lactic acid

Question 3

What is Glucose?

Answer 3

A major source of enegy for most cells in the body

Question 4

What is Aerobic respiration?

Answer 4

The process of releasing enrgy from glucose, without oxygen

Question 5

What is anaerobic respiration?

Answer 5

The process of releasing energy from glucose, without oxygen

Question 6

What is Aerobic exercise?

Answer 6

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 7

What is lactic acid?

Answer 7

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

Question 8

What is a cramp?

Answer 8

Painful, involuntary contraction of a muscle, usually caused by fatigue

Question 9

What are fats?

Answer 9

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

Question 10

What are carbohydrates?

Answer 10

The body’s main source of energy for high intensity exercise

Question 11

What are free sugars?

Answer 11

Extra sugar added to food and drink

Question 12

Short term effects on the muscle

Answer 12

Muscle fatigue

Question 13

What is a short term effect on the heart?

Answer 13

Your heart rate increases

Question 14

What is a short term effect on your breathing?

Answer 14

You use up more oxygen than you take in

Question 15

What is a short term effect on your breathing

Answer 15

You use up more oxygen than you take in

Question 16

Lever

Answer 16

A system of muscles and bones working together to help you move

When you exrcise, your muscles pull on your bones, and your bones create movement acting as levers

Question 17

Axis

Answer 17

An imaginary straight line around which the lever rotates

Question 18

Fulcrum

Answer 18

The point around which the lever rotates

Question 19

Load

Answer 19

The force that is applied by the lever system

Question 20

Effort

Answer 20

The force that is applied by the user of the lever system

Question 21

Three different classes of levers

Answer 21

First, second and third class

Question 22

What does saggital plane (flexion and extension) = with an example?

Answer 22

Front axis (flexion and extension) e.g. front somersault

Question 23

What does frontal plane (abduction and adduction) = with example

Answer 23

Saggital axis (abduction and adduction) e.g. cartwheel

Question 24

What are the characteristics of a front and back or piked somersault?

Answer 24

You move forward, with your left and right sides moving together in the same direction - in the sagittal plane

Your body bends on a line that runs horizontally from side to side - around your frontal axis

Jumped somersaults are similar. Front back somersaults are whole - body movements in the sagittal plane, around the frontal axis

Question 25

What are the characteristics of performing cartwheels?

Answer 25

You move sideways, from right to left or left to right - in the frontal plane

Your body rotates around a line that runs from the front to the back of your body - around your sagittal axis

Question 26

What are the characteristics of twists jumps in trampolining?

Answer 26

The key movement is not up or down, or from side to side, but around one spit - in the transverse plane

They twist around an invisible line that runs from head to toe around the vertical axis

Question 27

What is the composition of inhaled air?

Answer 27

Oxygen 21%
CO2 0.04%
Nitrogen 79%

Question 28

Immediate effects that an exercise session would have on the respiratory system?

Answer 28

Increased depth of breathing/heavy breathing

Breathing rate increases

Question 29

Two by-products released while producing energy aerobically

Answer 29

Carbon dioxide and water

Question 30

Two different blood pressures

Answer 30

Systolic and diastolic blood pressure

Question 31

How would effort allow the weight trainer to lift weight

Answer 31

Biceps muscle provide the effort which allows the weight lifter to lift the weight

Question 32

Why would it be important for your heart rate and breathing rate to increase while warming up

Answer 32

Need oxygen for muscles due to exercise. An increased breathing rate makes 02 available in body/lungs/increases oxygen intake. But needs (increased) heart rate to transpory/pump oxygen to muscles

Question 33

How can the heart increase cardiac output

Answer 33

Increase in heart rate and increase/larger stroke volume
