Hip
Shoulder
Name the hinge joints
- flexion and extension is the only movement possible
- similar to a hinge on a door
Elbow

-one bone rotates around another
Define the term ‘flexion’
Decreasing the angle at a joint
For example a bicep curl
Define the term ‘extension’
Increase in the angle of a joint
For example throwing a ball or a shotput ball
Define the term ‘adduction’
Movement of a joint towards the midline of the body
For example doing a star jump
Define the term ‘abduction’
Movement of the joint away the midline of the body
For example doing a star jump
Define the movement ‘rotation’
Moving of a limb in a circular motion in either direction
For example in golf when doing a drive shot
Define the term ‘circumduction’
this is where the limb moves in a circle. This occurs at the shoulder joint
For example when the arm is held straight at the elbow and the arm from the shoulder to the fingertips are moved in circles
For example over arm serve in tennis
Define the term ‘planter flexion’
Movement at the foot downwards towards the sole
For example pointing your toe in ballet
Define the term ‘dorsiflexion’
Backwards flexion of the foot
For example when walking bending your foot up
What’s the role of a ligament
To connect bone to bone
-are very strong
What’s the role of a tendon
Connect muscle to bone
Where is the muscle deltoid
•In your shoulder
Creates abduction at the shoulder and raise your arms sideways for example swimming
Where are the pectorals
•The front of the body in your chest
Creates adduction at the shoulder across the chest e.g. press up
Where are your abdominals
•Front of your body in your stomach
Allow you to flex your trunk e.g. situps
Where are your quadriceps
•Front of your leg
Make extension of the leg possible at the knee e.g. squats and kicking
Where is your Gastrocnemius
•The back of your lower leg
Allows you to stand on your tiptoes by creating extension at the ankle e.g. a Sprint start
Where is your tibialis anterior
The front of your lower leg
Responsible for Dorsiflexion and help you decrease the angle at your ankle for example making contact with a ball
Where are your hamstrings
The back of your upper leg
Allows flexion at the leg at the knee e.g. sprinting
Where are your gluteals
In your bum
Allows extension abduction and adduction at the hips e.g. squats and jumping
Where is your Latymers Dorsi
At your shoulder behind your back
Allows adduction at the shoulder e.g rope climb , star jump
Where are your triceps
Bottom of your upper arm below your bicep
Create extension of the elbow e.g. press up and throwing
Where is your bicep
The top of your upper arm
Allows flexion at the elbow e.g. drawing a bow in archery , push up, bicep curl
Where is your trapezius
Triangular muscle located at the back of the neck
Holding head in place e.g.Holding head up in a rugby scrum
Describe what a agonist is
-where the muscle shortens
-muscle is the prime mover
For example bicep curl = The bicep is the agonist
Describe what a antagonist is
-muscle lengthens
-muscle relaxes
For example in a bicep curl of tricep is the antagonist
Functions of the cardiovascular system
- transports oxygen ,carbon dioxide and nutrients around the body in the blood
- it causes clotting at open wounds and helps fight against disease
- System is able to cool the body when exercising by transporting blood closer to the skin
- deoxygenated blood is carried back to the heart and oxygenated blood is carried away from the heart to where it requires blood
Structure of the cardiovascular system and route
- right atrium receives Deoxygenated blood from the body
- The blood is forced into the right ventricle
- The blood then moves to the lungs via the pulmonary artery
- The left atrium receives the oxygenated blood from the lungs via the pulmonary vein and pushes it to the left ventricle
- this oxygenated blood is then sent round the body
Describe what a arteries is
- they carry oxygenated blood away from the heart
- they are made up of three layers with that outside being the strongest
- they are the largest of the vessels
Describe was capillaries are
- are the smallest vessels
- they form and network all of the body which connects veins and arteries
What are veins
-Carry deoxygenated blood towards the heart
What is vasoconstriction
- opening of the lumen
- blood vessels constrict getting smaller and tighter reducing bloodflow
What is vasodilation
- opening of the lumen
- blood vessels widen and allow increase bloodflow
What do red blood cells carry
They carry oxygenated blood around the body
What is vital capacity
The maximum amount of air that can be breathed in or out
What is tidal volume
The amount of air that enters the lungs during normal breathing when at rest
What happens to the air you breathe in and exhale
- the air you breathe in passes through your mouth nose and trachea
- it passes into the bronchi then into the bronchioles
- bronchioles are smaller tubular passageways inside the lungs running from the bronchus to the alveoli
- The final stage is where the gases are exchanged in the small sacks called alveoli
- The diaphragm is the main muscle of respiration it separates the chest cavity from the abdomen.
- contraction of the diaphragm , muscles expand the lungs during inspiration when you breathe air in
What is aerobic respiration
- with oxygen
-low intensity
For example running a marathon
-60-80% of your maximum heart rate
Glucose + oxygen —> carbon dioxide + water + heat + energy
What is anaerobic respiration
- without oxygen
- high intensity exercise , 100m spring
- 80% -90% of max heart rate
Glucose ——-> lactic acid + energy
Where does gaseous exchange take place
Alveoli
Describe inspiration
1) air breathed in
2) ribs raised
3) diaphragm contracts , shortens and moves down
Describe expiration
1) air out of mouth
2) ribs lowered or dropped down
3) diaphragm muscle relaxes and moved up
What sports uses aerobic exercise
- long distance cycling , running , rowing
- triathlon
Name the recovery processes
- cool down
- Ice bath
- massage
- rehydration
- intake of carbohydrates
What are the benefits of ice baths and who would use it ?
- game players might use ice baths after a intense match to help recovery
- Reduce risk of DOMS
- reduce swelling of a injured area
- dilates blood vessels = allows oxygenated blood to go to muscles to remove lactic acid
What are the benefits of a massage and who would use it?
- Gameplayers may use ice bath after a intense match to help recovery
- helps DOMS
- increase blood flow to remove lactic acid
What are the benefits of a cool down and who would use it
- any athlete can use a cool down after vigorous exercise
- it’s important to keep breathing/heart rate elevated ensures blood flow which helps convert lactic acid into glucose
- Prevents soreness DOMS
- brings heart rate and breathing slowly back to resting
- helps avoid dizziness and improves flexibility
