How does stroke rate differ between pool and open water?

Do you have the same stroke rate when swimming in the pool vs open water? How does your stroke differ?
Sabina Heywood

One of the biggest things that people who are used to swimming in the pool suffer with is changing their stroke in the open water. When you swim outdoors you should have a repertoire of strokes up your sleeve.

For example, if the water is choppy and you are swimming into the waves, you will need to shorten your stroke length and up your stroke rate. This allows you to make headway through the waves and chop. If you keep a long stroke with a low stroke rate, you might find you are getting pushed back!

What Science Says About Peeing in Your Wetsuit

Scientists are aware you urinate in your wetsuit. While many people feel like this is weird, it’s completely natural. It’s the norm amongst surfers – even if they don’t all admit to it. As a waterman, you’re experiencing a unique underwater phenomenon called immersion diuresis. Don’t panic though. There is a totally legit scientific reason for this.

So, why do we pee in our wetsuits and what is actually happening inside your body?

How dangerous is lightning to swimmers?

The other day I was swimming at Shepperton lake when a storm blew in. I saw a flash on the horizon, turned to a nearby swimmer and asked: “was that lightning?”

“Well, I don’t think you got caught by a speed camera,” he replied.

Thanks!

As most of you will know, lightning is supposed to bad for swimmers. Like any responsible venue operator would, the staff at Shepperton evacuated the lake, but it still took me a few anxious minutes to get out, during which time I saw several more lightning strikes. I started trying to figure out the probability of lightning hitting me or the lake, and what the consequences might be if it did.

About Ryan Stamrood's North Channel swim 2017

"Life is filled with certain obligations and responsibilities, but none more basic, primal or important than the responsibilities that we have to ourselves and each other"

The North Channel has played with many emotions over the years and Tuesday was no different. Ryan Stramrood made his call to take on his NC swim. There are always questions about the perfect day but there is equal stress for swimmers to make a decision or to risk the wait when flights are booked to leave and the wind we have been having this season.
Last min call and we were gone up the long 7 hr journey from SW to NE Ireland.

Bij het openwaterzwemmen deze zomer gingen de kwallen flink tekeer! Wat kan ik daar tegen doen?

De populaire vragenrubriek over al wat (niet) met zwemmen samenhangt van Frank Venema uit de exPLONSief (het clubblad van Plons).

Kwallen zijn weekdieren die voornamelijk uit water bestaan. Om vijanden van zich af te houden of prooien te verschalken hebben ze van die enge tentakels waaraan netelcellen (nematocysten) zitten. Die schieten kleine holle naaldjes af die gif in de huid spuiten van hun prooi. De prooi raakt verlamd, waarna de consumptie kan beginnen.

Drie soorten kwallen maken hoofdzakelijk de dienst uit in de Noordzee: de kompaskwal, de oorkwal en de blauwe haarkwal.

Plons Channel Team zwemmer over zwemmen en Pride

Steven Prins (38) is consultant bij het Philips Design for Excellence-programma. Hij is getrouwd en woont samen in Den Haag. 'De Philips boot heeft een grote impact op diversiteit.'

Diversiteit is een thema in het leven van Steven Prins. Niet alleen is hij getrouwd met een man afkomstig uit de Dominicaanse Republiek, ook werkt hij als consultant voor het Design for Excellence-programma, samen met Philips-collega’s die allerlei verschillende achtergronden hebben. 'Design for Excellence is een wereldwijd programma, in het leven geroepen om de diensten en producten van Philips te verbeteren, met als doel om één miljard euro te besparen. Door concrete besparingen toe te passen, is dat ons in drie jaar tijd gelukt. Als consultant bied ik het projectteam tools en tricks aan, zodat dit team de methodologie op de juiste manier kan toepassen. Daarnaast ben ik de schouder om op uit te huilen als het eens tegenzit en de persoon om champagne mee te drinken als er iets te vieren valt. Het begeleiden van grote veranderingen – en mensen zover zien te krijgen die veranderingen te omarmen – is wat mijn werk zo leuk maakt. Met een eigen team een grote verandering in de Philips-organisatie realiseren, is wel een droom van mij.'

Australian teen just 'unfortunate' to be attacked by meat-loving sea fleas

It’s safe to go back in the water, says marine biologist who identified the miniature attackers as lysianassid amphipods.

The “meat-loving” marine creature that ate at the legs of a Melbourne teenager has been identified as a flesh-eating sea flea, known as a lysianassid amphipod.

Marine biologist Dr Genefor Walker-Smith said the creatures, which left 16-year-old Sam Kanizay with significant bleeding from his legs, were a small, scavenging crustacean that usually fed on dead fish or sea birds.

Kanizay said on Monday he was soaking his legs at Brighton beach when he felt the creatures attack, causing wounds that would not stop bleeding.

Swimming the Channel, a lake or the ocean, all involve the soul as well as the body

Why do we human beings swim? We don't need to, after all. I've just climbed out of the English Channel in Devon, just before dawn, having left my warm bed to plunge my body in a body of water, which rises at springtide as if to drag me in. I do this every morning, more usually from my home waters in Southampton, where the confluence of cold waters from two rivers turns the experience into an even colder shock.

Galway researchers find most effective treatment for jellyfish stings

Seawater, ice packs and urine all have one thing in common – they are all associated with treating jellyfish stings.

Now newly published research has confirmed that such antidotes are not only useless, but may actually make stings worse.

The study by scientists at NUI Galway and the University of Hawaii-Manoa evaluated the standard practice in Ireland for treating stings by the Portuguese man o’ war (Physaliaphysalis) – as in rinsing with seawater and applying ice.
