Fizyk pewnie tez. Jak podaje Rafal sami plywacy nie znaja jeszcze swych pelnych mozliwosci.
Rafal pisal, ze do czynnikow lagodzacych naleza wyzsza temperatura powietrza pozwalajaca na ogrzanie glowy i ramion, oraz zasolenie morskiej wody.
Nizej bardzo ciekawy opis przygotowan do plywania zima w wodzie slodkiej, chlodniejszej niz z rekordu Rafala, a nawet bliskiej temperaturze zamarzania, i z ujemna temperatura powietrza.
Ram Barkai, to ten, ktory mial sie pluskac w ciesninie, kilka dni po Rafale.

". The cold water tightens your muscles dramatically and the only
way to be able to move and cover distance without panic is to control your breathing (while inhaling
air which is a few degrees colder than the water!)
The plan so far is as follows:
• Water temperature is between 1C to 2C – a mile swim 30 minutes
• Water temperature is between 2C-3C - 2km swim 40minutes
• Water is above 4C – 3km swim 1 hour
We are not sure which one is more challenging but at these temperatures, every degree makes a big
difference and time spent in the water is critical. It is difficult to comprehend that in 2C, which is
extremely cold, moving to 1C is TWICE as cold. We were swimming at 9C the other day (which was
clenching to most parts of the body…) can you imagine swimming in 3 or 9 times (1C to 3C) colder
water?"

tu opis kapieli treningowej w plastikowym baseniku:
"We had two tubs one at 0.4C for Ram and one at 3C for Andrew.
Ram spent 3 minutes in 0.4C. It is fresh water so getting to 0.4C
means just above freezing temp. The way they do it, they fill the tubs
with 2-3 degrees Celsius water and start filling it with ice to lower the
temp. After 3 minutes Ram joined Andrew at the 3C tub. We spent total of 10 minutes. We are fine.
Hands and fingers are extremely painful, but nothing fell off."

artykul ma juz trzy lata. Ciekawe czy panie i panowie plywacy zblizyli sie w tym czasie do poznania swych granic?
