Analiza plavanja na 400m prosto pri predmetu Plavanje 1 : diplomsko delo

Foški, Tajda (avtor), Kapus, Jernej (mentor)

V sklopu študija na Fakulteti za šport je eden od obveznih in izbirnih predmetov tui Plavanje 1 z osnovami reševanja iz vode. Tekom semestra se študenti in študentke med drugim spoznajo tudi s tremi osnovnimi plavalnimi tehnikami – kravl, prsno in hrbtno. Na koncu semestra je ena od praktičnih izpitnih nalog tudi plavanje 400m prosto, kjer študenti in študentke pokažejo svoje tehnično znanje in telesno pripravljenost. Za opravljen izpit morajo študenti in študentke 400m odplavati v za to določenem minimalnem času. Cilj naloge je bil ugotoviti, kakšne plavalne tehnike izbirajo študenti in študentke na izpitu, če ta izbira vpliva na njihov končni čas in če obstajajo kakšne razlike v izbiri tehnike glede na spol. Analiza je bila opravljena na vzorcu 151 študentov (87) in študentk (64), ki so v študijskem letu 2016/2017 opravljali predmet Plavanje 1 in na koncu tudi pristopili k izpitu ter ga uspešno opravili. Ugotovili smo, da se študenti in študentke poslužujejo vseh treh tehnik, v samostojni obliki ali kombinaciji dveh oz. treh tehnik. Kar 56% študentov in študentk se je odločilo za kombiniranje plavalnih tehnik, od teh jih je 75% izbralo kombinacijo prsno-kravl, 23% jih je izbralo kombinacijo prsno-kravl-hrbtno, 2% jih je izbralo kombinacijo kravl-hrbtno, noben pa ni izbral kombinacije prsno-hrbtno . Več študentov kot študentk je vseh 400m plavalo kravl in več študentk kot študentov je vseh 400m plavalo prsno. Zanimalo nas je tudi, če je končni čas odvisen od tehnike in rezultati so pokazali, da je povprečen končni čas dosežen s kravlom za kar več kot minuto hitrejši od povprečnega časa prsnega in kombinacije tehnik. Zaradi velikega deleža kombinacij tehnik, smo te bolj podrobno preučili, predvsem kombinacijo prsno-kravl. Analizirali smo delež kravla in prsnega za posamezno dolžino ter ugotovili, da prve tri in zadnji dve dolžini več kot polovica študentov plava kravl. Glede na to se spreminja tudi povprečen tempo na 50m, ki je hitrejši takrat, ko je več študentov plavalo kravl in počasnejši, ko je več študentov plavalo prsno. Primerjali smo tudi povprečen končni čas z deležem kravla v celotnih 400m. Rezultati so pokazali, da je končni čas odvisen od deleža kravla in da se s padanjem njegovega deleža kravla podaljšuje tudi čas plavanja na 400m. Na koncu pa nas je zanimala razporeditev tehnik glede na spol. Potrdili smo hipotezo, da se več študentov odloči za kravl. Zanimivo pa je bilo tudi, da je bila podobna razlika v deležih tudi pri prsnem le v korist študentk. Za kombiniranje tehnik se je odločil podoben odstotek študentov (56%) in študentk (54%).

Izvleček

One of the subjects on Faculty of sports that students must attend is Swimming 1 with basics of rescuing from water. Through the semester students get to know three basic swimming techniques – freestyle, breaststroke and backstroke. At the end of the semester they have to show their technical skills and physical performance on practical exam where they have to swim 400m. To pass the exam they have to finish on time designated for minimal grade. The main purpose of our thesis was to find out which techniques does students choose for their exam, if the final time is affected by swimming techniques and if there are any differences regarding the gender. Analysis was done on the 151 students, 87 males and 64 females, which attended the subject in school year 2016/2017 and successfully finished swimming 400m with the positive grade. We established that the students choose all three techniques, some swam whole 400m in one technique and the others combined two or three techniques. As much as 56% of students decided to combine techniques, of which 75% combined breaststroke freestyle, 23% combined all three techniques, 2% combined freestyle and backstroke, but there was no one who would combine breaststroke and backstroke. More males than females swam the whole 400m in freestyle and more females than males swam the whole 400m in breaststroke. Our concern was also the final time and its correlation to swimming technique. Analysis showed that the final time of freestyle was faster for more than a minute from final times of breaststroke and combined techniques. Because of a high percentage of students who combined techniques we looked into these more exhaustively, especially into freestyle and backstroke combination. First we analysed the share of freestyle and breaststroke for individual length and found out that more than half of students swam freestyle in the first three and last two lengths. Also, the average swimming pace was correlating with the percentage of freestyle in each 50m. When the percentage was higher, the pace was faster and vice versa. There was also a correlation between the percentage of freestyle in whole 400m and final time. As the percentage of freestyle grow the final time was getting faster. Finally we were interested how swimming techniques were distributed regarding the gender. We confirmed the hypothesis that more males choose freestyle than females, while more females choose breaststroke than males. For combining techniques there was similar percentage of males (56%) and females (54%) who decided to do so.
