4

What’s isotonic contractions

It occurs when there is movement of the body the ends of the muscles move closer together to cause the movement

New cards
5

What’s isometric contractions

Contractions that happen when the body is held in the same position

The length of the muscles stay the same during theses contractions

New cards
6

What’s concentric contraction

The muscles shortening

New cards
7

What’s eccentric contractions

The muscle lengthening and is under tension

It provides control of the movement in the downward phase and works to resist the force of gravity

New cards
8

How does the skeleton support the body

The bones are solid and rigid which keeps the body upright and holds the rest of the body in place

New cards
9

How does the skeleton help the body move

Helps the body move by providing anchor points for the muscles to pull against

New cards
10

How does the skeleton provide structural shape and points for attachment for the body

The skeleton gives us our general shape such as height and build

It also provides anchorage points for the muscles to attach to

New cards
11

New cards
28

What is aerobic respiration and what actives is used in

Energy is created with presence of oxygen

Low intensity long duration activities

New cards
29

What is anaerobic respiration and what happens when you excercise for

Energy is created without the presence of oxygen which produces less energy than aerobic respiration

After a short period of time performance drops as Lactic acid builds up

New cards
30

Explain what oxygen debt is

The amount of oxygen needed to break down the lactic acid

Lactic acid is produced by not having enough oxygen to break it down the glucose

Oxygen is paid back when the performer has stopped working

New cards
31

How we breathe in

The diaphragm contracts and flattens

The intercostal muscles contract which cause the rib cage to rise which increases the chest cavity size and volume

This reduces the pressure in the chest cavity due to this the air passes from the higher pressure outside of the lungs to the lower pressure inside the lungs

Causing the lungs to expand and fill the chest cavity

New cards
32

How do we breathe out

The diaphragm relaxes and bulges up

The intercostals muscles also relax causing the rib cage to lower decreasing the size and volume of the chest cavity

This increases the pressure of the air in the lungs causing it to be expelled

The air passes from the high pressure in the lungs to the low pressure in the bronchi and trachea

New cards
33

What do alveoli do and how does it do it

Alveoli is where the gaseous exchange takes place

Oxygen enters the blood stream to be sent to the heart

Carbon dioxide replaces the oxygen in the alveoli so that it can be removed from the body

New cards
34

What are the key features alveoli

Walls are one cell thick

Moist easy to exchange gases

Very small

Millions within the lungs.

Covered with huge networks of capillaries

New cards
35

New cards
36

What’s tidal volume

Amount of air inhaled / exhaled per breath

New cards
37

What is minute volume

Respiratory rate x Tidal volume

New cards
38

What’s residual volume

The volume of air that remains in the lungs after maximal expiration

New cards
39

What is expiratory reserve volume (ERV)

The additional air that can be forcibly exhaled after expiration

New cards
40

What’s is inspiratory reserve volume (IRV)

The additional air that can forcibly inhaled after inspiration

New cards
41

What happens to your breathing during exercise

RV - Increases

TV - increases

MV - increases

Residual volume - stay the same

ERV - decreases

IRV - decreases

New cards
42

What happens to the muscles during expiration

The abdominal muscles contract assist the performer exhale air

New cards
43

What is the function of the respiratory system

To bring into the body and remove carbon dioxide

New cards
44

what is the pathway of air into the body

When we breathe in air moves through the mouth and nose

The air travels down the trachea

The inner surface of the trachea is covered in tiny hairs called cilia which catch particles of dust

The trachea is kept open my rings of cartilage

The trachea divides into two bronchi one enters each lung Which divide into bronchioles

At the end of the bronchioles their are a bunch of alveoli in a clump

At the alveoli gaseous exchange occurs and the capillaries carry blood that surround each alveoli resulting in oxygen being passed into the bloodstream

New cards
45

What is heart rate

Beats per minute

New cards
46

What is stroke volume

Blood pumped out per beat

New cards
47

What is cardiac output

New cards
56

What does the aorta do

Artery that takes oxygenated blood from the left of the heart to body tissues / cells

New cards
57

What does the pulmonary artery

The only artery in the body that carries deoxygenated blood

It takes the blood from the right side of the heart to the lungs

New cards
58

What is diastole phase

When the heart relaxes and fills with blood

New cards
59

What is systole phase

When the heart can contracts and sends blood out of it

New cards
60

What is blood pressure

The force exerted by circulating blood on n the walls of the blood vessels

New cards
61

What does systolic mean

The heart contracts/beats

New cards
62

What does diastolic mean

In between heart beats when the heart is relaxed

New cards
63

What does red blood cells do and what do they contain

Carry oxygen around the body

Produced in the bone marrow of our long bones

Contain haemoglobin to which oxygen attaches to create oxyhaemoglobin

New cards
64

Name everything you know about arteries

Carry Blood away from the heart

Most arteries carry oxygenated blood

Thick walls to withstand the high blood pressure

Small / narrow lumen so that the blood is forced around the body at a high pressure

Strong elastic walls that can easily increase and decrease in diameter

New cards
65

Name everything you know about veins

Carry blood towards the heart

Most veins carry deoxygenated blood

Thinner walls as the blood is pumped through at a low pressure

Contain valves to prevent back flow of blood due to low pressure

New cards
66

Name everything you know about capillaries

Where gaseous exchange takes place

One cell thick to enable substance to enter and leave the blood stream

Alveoli and body tissue surround it to allow gaseous exchange to take place

Huge network throughout the body linking arteries and veins

New cards
67

What is blood shunting

When vasoconstriction and vasodilation work together

New cards
68

What is vasoconstriction

Reducing the diameter of small arteries

This reduces the blood flow to certain parts of the body

New cards
69

What is vasodilation

Increasing the diameter of small arteries to increase blood flow to certain parts of the body

New cards
70

When is vasoconstriction used in exercise

Reduces blood flow to the parts of the body not needed during exercise

New cards
71

When is vasodilation used in exercise

Occurs around the working muscles so that more blood carrying oxygen can get to the muscles to create more energy

This allows the performer to maintain their standard for longer

New cards
72

What is the aerobic respiration equation

Oxygen + glucose → carbon dioxide + water + energy

New cards
73

What is the anaerobic respiration equation

Glucose → lactic acid + energy

New cards
74

What is excess post exercise consumption (EPOC)

Maintaining an increased rate of oxygen intake after the anaerobic which allows the performer to repay the oxygen debt

New cards
75

What are the 4 ways to recover after exercise

Rehydration - drinking water is vital to restore the fluids lost during exercise

Manipulation of diet - carbs will help to restore the glucose that has been lost

Massage - it increases blood flow which reduces inflammation and DOMS

Ice baths - it repairs the micro tears that occur in muscles fibres prevent DOMS and inflammation

New cards
76

What are the immediate effects of exercise

Increased heart rate - to increase blood flow to the working muscles, oxygen delivery and carbon dioxide removal

Increased breathing rate - speeds oxygen delivery and carbon dioxide
