0 Swimming is the one sport that can save your life. 1 There are four strokes, front crawl, backstroke, breaststroke and butterfly, and in England children are meant to swim at least 25 metres by the end of primary school. 2 Water has its own rules: real drowning is often silent, with the head low and no waving, so if someone looks wrong, shout for the lifeguard at once. 3 Never jump in after a person or a dog: call, reach or throw from the bank. 4 Fall into cold water and your body gasps for about a minute, so the RNLI says Float to Live: lean back, spread your arms and legs, and float until your breathing calms, then call for help. 5 On a bike, a level, buckled helmet and brakes that work matter more than looking cool. 6 Picture the ABC check on the drive, Air, Brakes, Chain, then Bikeability training before you ride on the road. 7 The four swimming strokes are front crawl, backstroke, breaststroke and butterfly; in front crawl the arms do most of the pushing and the legs kick mainly to keep the body flat. 8 In England the school curriculum says children should be able to swim at least 25 metres by the end of primary school. 9 Cold water makes you gasp; getting in slowly lets the body settle, and open water is colder and deeper than a pool and has currents, so swim outdoors only where there are lifeguards. 10 There is no good evidence that swimming after a normal meal makes you drown; after a huge meal a short rest is just for comfort. 11 Stinging eyes and the strong pool smell come mostly from chloramines, made when chlorine mixes with sweat and wee, so shower and use the toilet before you swim. 12 A person who is drowning usually can't shout or wave and can look calm, with the mouth at the water line; tell a lifeguard straight away. 13 People who jump in to rescue someone, or a dog, often get into trouble themselves; call 999 (or 112) and reach or throw something from the bank, and never go in. 14 Cold shock, gasping and fast breathing, lasts about the first minute or two; the RNLI advice is Float to Live: lean back, spread your arms and legs, and float until breathing calms. 15 A bike helmet's foam crushes in a crash so the brain is shaken less; it should sit level, about two fingers above the eyebrows, buckled snugly, and be replaced after a big crash. 16 In the UK the Highway Code advises cyclists to wear a helmet. 17 Worn brake pads or loose cables mean you can't stop in time; the ABC check is Air in the tyres, Brakes and Chain. 19 The big thigh muscles push the pedals down, and you stay balanced mostly through tiny steering movements; moving forward makes balancing easier, and gears help on hills. ← previous Football: positions, rules and scoringnext → Running, gymnastics and martial arts↑ back to Medicine This page in Markdown → https://md.mova.elamur.ai/free/en/corpora/school/medicine/42-swimming-and-cycling/
