Ronjenje, sport u kojem se uživa


Ronjenje je danas jedan od športova koji se najbrže širi svijetom, a oduvijek je postojala čovjekova želja da se spusti ispod površine mora.

Najvažniji posao ronilaca u prošlosti bio je spašavanje tereta s potonulih brodova i o tome postoje pisani podaci. Ronilo se isključivo na dah, a obuka je započinjala još u djetinjstvu. Kamenje se upotrebljavalo umjesto utega, ronilac bi bio vezan konopcima, a uranjao bi do 31 metar ispod površine.

Otkrivanje dekompresijske bolesti

U početku se dekompresijska bolest nazivala cassions disease, jer je njezino pojavljivanje bilo vrlo učestalo među kesonskim radnicima, koji su radili na projektima iskopavanja temelja za most ili konstrukcija dionica tunela.
Što je bilo više projekata za rad pod vodom, to je bolest poprimala šire razmjere.

Godišnje se u hrvatskoj proda više od 40000 ronilačkih iskaznica što i ne znači da na Jadranu i roni toliko ronioca. Pretpostavlja se da je taj broj puno veći.

Kod S.C.U.B.A. ronjenja podrazumjevamo ronjenje sa vlastitim spremnikom komprimiranog zraka i pripadajućom obaveznom opremom (boca sa ventilskom grupom i regulatorom, kompenzator plovnosti,maska,peraje,olovo i mokro ili suho odijelo. Takođe je dobro imati ronilački kompjuter sa dubinomjerom i računalom dekompresije

Ronjenje na dah ili apnea je ronilačka disciplina kojom se ljudi bave od davnina. Ispočetka smatrani prirodnim fenomenima, tek su u nekoliko posljednjih desetljeća počela ozbiljna znanstvena istraživanja koja objašnjavaju sposobnosti ljudi da se pod vodom zadrže po nekoliko minuta i zaranjaju na dubine i do 200 metara.

Najbolji trening za ronjenje na dah jest ronjenje na dah. Zvuči jednostavno i pomalo smiješno, ali to je zaista najspecifičniji trening.

Statična disciplina

U ovoj disciplini ronioc zadržava svoj dah koliko je najduže moguče i koliko mu njegov dišni sustav dopušta. Njegovo tjelo je uronjeno u vodu ili na površini. Static apnea je jedina disciplina koja mjeri trajanje i jedna od dvije discipline u kojoj se može natjecati timski.

Dinamična disciplina

Ronioc roni horizontalno pod vodom u pokušaju da prijeđe što veću udaljenost. Za pokretanje nije dozvoljena nikakva druga pomoč osim peraja ili monoperaje. Natjecanje se može odvijati u bazenu minimalne dužine 25 metara.

Dubinska disciplina

Za uron i izron ronioc koristi peraje ili monoperaju i/ili koristi ruke bez da se povlači po konopcu ili da mjenja balast s kojim je uronio. Dopušteno je jednom dotaknuti uže da bi se zaustavio pri uronu i krenuo s izronom. Ni u kojem trenutku za vrijeme zarona ne smije mjenjati količinu olova koju nosi.
