Lesson 8.1
Internally Caused Injuries
Overuse (chronic) injuries – these come about through hard training or performing too much or for too long.
- Pressures nowadays to do well in sport are so great that performers get a temptation to do far too much which leads to injuries.
- Performers can suffer stress fractures in bones caused through too much running, as well as tendon and muscle injuries.
- Footballers get knee and ankle injuries due to a lot of twisting and turning.
- Tennis players suffer from ‘tennis elbow’, caused by the forced straightening of the arm during play.
- And so on for different sports.
- Strain is required in the majority of sports, but what is important is that the performer does not overdo it and be ready to cut down on training or even stop, if there is any sign of injury.
- Carrying on, will only make things worse.
Sudden (acute) injury – these are caused instantly by such things as overstretching or twisting or turning quickly.
- They may be caused by tiredness or fatigue.
- Many of these types of injuries happen quite late on in a game or a match. A lack of suitable warm-up can also be a cause, or trying to do something which is either too difficult or which is clearly dangerous.
- It also happens when you are not warmed up well.
Externally Caused Injuries
These are caused by factors other than the performers themselves.
- It could be the equipment used
- the playing conditions or
- an opponent.
They can be listed under the following headings:
- Impact injuries – these are injuries such as cuts, bruises and fractures. Impact can be caused by another player (mainly in team games were contact is inevitable) such as bumping together, falling over another player, etc. Impact can also be made with equipment such as getting hit with a hockey stick, with a ball, soccer boots, a post, etc. The playing surface is also a very common cause of these injuries. Both outdoor and indoor surfaces should be taken into consideration.
- Foul play – this involves other players, usually opponents. These injuries at times can be very serious such as having bad tackles, pushing over players, etc. So rules are there to prevent as many injuries as possible.
- Accidents – no matter how many safety precautions are taken, there will always be accidents. They occur in all physical activities, but because some sports are more dangerous than others, the accidents will be more common and more serious, e.g. skiing, bungee jumping, boxing, wrestling
- Equipment - a simple thing such as a blister can be caused by the equipment. Often injuries are caused by damaged or faulty equipment which is not doing its job properly, though it does not necessarily have to be faulty to cause an injury e.g. running long distances will automatically get you blisters, no matter how specialist the running shoes are.
How can you avoid injury?
- Make sure you are fit for the activity
- Make sure you develop the right techniques
- Play at the right level / right age
- Know the rules of your sport and obey them
- Make sure you are wearing the right kit
- Make sure the equipment you use is in good repair
- Lift and carry equipment with care
- Watch out for hazards (environment) in the playing area
- Warm up correctly
- Cool down correctly
Preventing injuries can be summarised in the following points:
- Preparation – involving training, warmup and physical state of the athlete.
- Equipment – involving the correctness and conditions of them.
- Participation – involving fair play and officials.
- Environment – involving uncontrolled and controlled environment.
Lesson 8.2
EMERGENCY ACTION (I)
What do we do when someone collapses?
- If someone collapses we must follow the DRABC routine.
- This routine tells us what to do in the right order.
- The aim of DRABC is to keep the person breathing until an ambulance arrives.
- As without oxygen, the brain is damaged within just three to four minutes and dead within ten.
Danger:
- Check for danger first, such as equipment in the way, electricity, gas, fire or fumes.
- Your own safety comes first, so make sure you do not put yourself in danger by helping someone else. Call for help immediately.
- If there is no danger, clear the area around the casualty.
Response:
- Shake the casualty gently by the shoulders and shout ‘can you hear me?’
- If the casualty shows a response, he/she is conscious.
- If the casualty can speak, find out where he/she is in pain. Take action if you can help such as bleeding, broken leg, etc.
- If there is no response the casualty is unconscious.
Airway:
The tongue can block the airway so:
- Loosen any tight clothing.
- Raise the chin and tilt the head back to open the airway fully.
- Remove any obvious obstruction such as a gum. Make use of a tissue to remove any vomit.
Breathing:
- Look for the chest rising and falling. Listen for breathing sounds.
- Feel for breath on your cheek.
- If the casualty is breathing, place him/her in the recovery position.
Circulation:
- Check the pulse under the ear or from the wrist.
- The pulse shows the heart is beating and the blood circulating. So you need to give mouthtomouth ventilation to restore breathing (the kiss of life).
- If there is no pulse you need to give both cardiac message and mouth to mouth ventilation, to restore circulation and breathing.
All of these things can be done until help arrives generally from an ambulance. But your actions can save someone’s life, so every second counts.
When calling an ambulance be clear to specify what the injury of the casualty is and where he/she stands.
For an ambulance dial 112.
Important Point about injuries:
- We must not move an injured sportsperson if we are at all worried about a spinal injury.
- Signs of this would be:
- head injuries,
- back injuries,
- unknown cause of unconsciousness,
- casualty cannot move,
- casualty doesn’t feel the legs or arms, etc
In an emergency we must:
- assess the situation
- make everyone safe
- send for medical help
- give emergency aid

Lesson 8.3
EMERGENCY ACTION (II) L
Mouth-to-mouth ventilation (MMV)
If a person has stopped breathing use mouth-to-mouth ventilation to get the person to breath again. Here you force air from your lungs into the casualty’s lungs. The oxygen in this air can keep the casualty alive.
The following steps should be taken for mouth-to-mouth ventilation:
- Clear his/her mouth and throat of any obstruction.
- Open his/her airway by lifting the jaw and tilting the head well back.
- Check for breathing with your face close to his/her mouth. Look for chest movement. Listen for sounds of breathing. Feel his/her breathe on your cheek.
- If he/she is not breathing, pinch the nose. Take a deep breath. Seal your lips around his/her mouth. Blow into his/her mouth and watch the chest rise. Take your mouth away and watch his/her chest fall back.
- If his/her chest does not rise, check again for an obstruction in the mouth. If he/she is still not breathing, slap him/her firmly on the back to clear the blockage or grab the person from the stomach and squeeze upwards.
- Check his/her pulse before continuing. If there is no pulse start chest compressions.
- If he/she has a pulse and his/her chest has risen, continue blowing
into the mouth. Give breaths every five to six seconds and
continue until he/she starts to breath again. Then put him/her into
the recovery position.
Cardiac arrest is
- When your heart stops beating, e.g. during a heart attack.
- When it stops the circulation and pulse stop too.
Cardiac Massage or External Chest Compression
- A way of squeezing the heart so that blood is forced out of it and round the body.
- It must be combined with mouth-to-mouth ventilation so that the blood gets oxygen too.
A defibrillator
Is a special machine which gets the heart to start beating properly.
How to do cardiac massage or cardio pulmonary respiration (CPR)
- Place the casualty on his/her back. Put the heel of one of your hands on the breastbone, keeping your fingers off the ribs.
- Cover this hand with the heel of your other hand and interlock your fingers.
- With your arms straight, press down vertically on the lower half of the breastbone in order to move it 4-5cm and then release the pressure. Complete 30 compressions. The compressions should be regularly and smooth, not jerky and jabbing. Count to get yourself working at the right speed.
- Move back to the casualty’s head, re-open their airway and give two breaths of mouth-to-mouth ventilation.
- Continue with thirty compressions followed by two full ventilations, checking for a pulse after the first minute. Then keep checking the pulse every three minutes.
- As soon as the pulse returns, stop the compressions. Continue with the mouth-to-mouth ventilations until natural breathing has been restored
If we are not alone (MMV)
If we are not alone, but have some help available, we need to do one of the following:
- We can do the MMV and the chest compressions alone for a period of time. This gives the other helper some rest. Then we can change over.
- We can work both at the same time by having one helper doing the chest compressions and the other doing mouth-to-mouth respiration.
For children
- For children, open the airway and seal your lips around the mouth and nose and breath gently into the lungs at a rate of 20 breaths per minute (whereas for adults 12 breaths per minute).
- Chest compressions also need to be done more lightly:
- For children, use light pressure with only one hand at a rate of 100 compressions per minute, with 5 compressions to one ventilation.
For babies
- For babies, use the same technique but only puff gently into the lungs at a rate of 20 per minute.
- If the baby is not breathing slap him/her on the back to remove any obstacles that might be in the throat.
- Chest compressions also need to be done more lightly:
- For babies, use only two fingers with very light pressure.
The Recovery Position
We always use the recovery position for an unconscious person who is breathing. The following procedure should be tackled when about to place a casualty in the recovery position:
- With the casualty lying on his back, tilt the head back and chin up to open the airway.
- Straighten the legs.
- Move the arm nearest you so that it looks like the arm of a policeman stopping traffic.
- Bring the other arm across the chest. Arrange so that the casualty’s cheek rests on the back of this hand. Keep your hand on this hand for step v.
- With your other hand, reach across the casualty’s far leg. Lift it so that the knee bends to a right angle. Then pull it to roll the casualty towards you.
- Once the casualty is on his side, gently tilt the head back, to keep the airway open. Use his hand under the cheek to hold it like that.
Lesson 8.4
BONE AND JOINT INJURIES
Fractures: (hard tissue injury)
A facture is a break in a bone. There are two types:
- a simple (closed) fracture – where the bone breaks but stays under the skin.
- a compound (open) fracture – where the bone breaks through the skin.
Complicated fractures
- Involve damage also to nerves and muscles.
- The damage could cause heavy bleeding which could be more serious than the break itself.
- All fractures are serious and need urgent medical treatment.
Stress fractures
- Are cracks that appear along the length of the bone and are caused by repeated stress applied to the bone over a long period of time.
- These are also known as calcifications.
