  1. YEAR 12 SLR AQUATICS

  2. Types of Stroke • Swimming Strokes- List the various strokes: Freestyle, Breaststroke, Backstroke, Butterfly, Survival Side stroke, Survival Backstroke See stroke technique on Wiki page

  3. Common Features • Hand movement: An S pattern ensures a propulsive force by pulling through the water in a curved pathway. Hands should enter and leave the water cleanly to prevent drag and maintain position. • Streamline body position: A horizontal and straight body position should be maintained to create as little resistance as possible. • Stroke technique: each stroke has its own characteristics.

  4. Stroke Choice Factors to consider include- • 1) Speed of the stroke: when speed is needed a swimmer should choose a low resistance stroke. Eg. Freestyle or backstroke. • 2) Energy expenditure: Is greatly reduced when strokes are swum slowly and no body parts are lifted out of the water. Eg. survival strokes.

  5. Stroke Choice • 3) Propulsion: when high speeds are not needed strokes with high level of propulsion should be used. Eg. Breaststroke and Sidestroke. • 4) Vision: Needed for many survival and rescue situations where it is important to keep the head out of the water.

  6. Stroke Analysis • In groups students examine an individual stroke’s technique. Students discuss advantages and disadvantages, timing and breathing.

  7. Water Safety Factors that contribute to safety: • a concern for others and self. • awareness of dangers • minimising risks • preventing accidents and knowing how to act in an emergency

  8. Water Environments- Inland Rivers- dangers include : - Currents: are unpredictable and vary in relation to flooding, river course and hazards. Also the strength of the current depends on factors including volume of water, width and depth of the river, rainfall and tidal changes. - Crumbling banks- can lead to people accidentally falling in. • Uneven river beds- can cause difficulties for inexperienced swimmers. • Submerged Obstacles: Obstacles such as trees, branches, rocks of rubbish can be very dangerous when diving and/or swimming

  9. Water Environments- Inland • 2) Lakes and Dams- Dangers include:- - River entry points: Strong currents and soft uneven lake beds. - Water temperature:Sudden immersion in cold water can cause shock. - Unclear water: unable to see bottom and any obstacles

  10. Water Environments- Inland 3) Home – Dangers include: • Unfenced home pools/dams. • Gates and barriers left open for easy access. • Fish ponds in gardens that may attract young children • Domestic baths are dangerous for the very young or elderly *In addition to constant supervision what other safety measures need to be in place? • Eg. self closing gates, install rigid covers, keep ponds covered, empty wading pools immediately after use, close washing machines etc.

  11. Water Environments- Open What is an open water environment? • Beach, surf, ocean, river mouths. The risk factors for danger change. Eg. Waves in open water are much larger, stronger and more consistent. Therefore special skills and knowledge are required when swimming.

  12. 4) Local Swimming Pool- Dangers include: • Crowded pool • Not following rules • Diving in

  13. 5) Ocean / Beach Dangers include: • Waves • Tidal currents • Rips • Gutters/ sandbanks

  14. 6) Fishing Dangers include: • Slippery rocks • Tidal waves / rising water • Changes in weather

  15. Open water: Types of wave Plunging:break with great force, can push swimmers to the bottom, break in shallow water. Spilling:the crest tumbles down the wave, usually breaks as the tide is going out. Surging:a non breaking wave occurring in deep water, can still have significant power and push swimmers off their feet. ** Students complete diagrams for each wave type and provide instructions on how swim in waves.

  16. Boating Precautions include: • Carry PFD for each person on board • Not overloading boat • Check weather conditions before leaving • Not going alone

  17. AQUACODE RLSSA ( royal life saving society Australia) developed three basic rules: • Go together: never swim or play near water alone • Stay afloat and wave: stay calm, float on your back and wave for assistance. Hold onto floating object in available. • Reach to rescue: reach with an object to rescue.

  18. Open Water: Safety *In groups students develop a set of key safety guidelines for swimming in open water. Eg. have a sound knowledge of waves, rips and currents, swim across a rip if caught, if caught swim parallel to the beach and return with the breaking waves, if unable to escape float and wave for help, swim between flags, swim with others, know your ability, keep a reference point, follow lifeguard instruction

  19. RESCUE PRINCIPLES Awareness : • Recognise the problem early eg ability of the swimmer. • Recognising potentially dangerous situations eg falling into water, swimmer looking fatigued, swimmer in rip.

  20. RESCUE PRINCIPLES Assessment: • Recognise own skill, fitness and strength to perform rescue. • Note the number and condition of people in difficulty. Eg radio in for assistance • Is there any other form of help available eg IRB vs swimming with tube. • Dangers in water • Distance to safety eg board - IRB

  21. RESCUE PRINCIPLES Action • Safety of the rescuer must be the first priority. Only attempt wet rescues if no other option. • Use bystanders to get further help / medical assistance. • Select most appropriate rescue aid. • If more than one casualty, decide which casualty should be rescued first.

  22. Rescue aids ???? • Esky lid • Body board • Ball Others ??
