Abstract

Snaga i brzina su čimbenici koji zajedno s fiziološkim i tehničkim utječu na uspješnost u plivanju. Primarni cilj ovog znanstvenog istraživanja bio je definirati povezanost između 8 različitih parametara dobivenih testom dinamometrije plivanja i rezultata u disciplini t50 slobodno. Sekundarni cilj ovog znanstvenog istraživanja bio je izraditi računalni program koji će olakšati izračunavanje i analizu sila zaveslaja u plivanju izmjerenu pomoću dinamometra. Ostvarenjem dvaju ciljeva moglo bi se zaključiti koji je čimbenik važniji, snaga ili tehnika. Uzorak ispitanika obuhvaća 8 vrhunskih plivača Hrvatskog akademskog športskog kluba Mladost. Testiranje je obavljeno pomoću dinamometrijske sonde te su izmjerene sile analizirane pomoću računalnog softvera. Za povezanost između parametara sile zaveslaja u mjestu i t50 kraul korištena je metoda korelacije i multiple regresijske analize u računalnog programu Statistica. Rezultati korelacije pokazuju statistički značajnu povezanost jedino između t50 kraul i ImpF (p= 0,716793), dok multipla regresijska analiza nije pokazala značajnu povezanost. Od ostalih istraživanih parametara korelacija pokazuje malu povezanost s fatInd (p= 0,309155), RDF (p= -0.553791) i Fmax/kg (p= 0,346679). To upućuje na zaključak da u kratkim natjecateljskim disciplinama nije samo važno proizvesti maksimalnu silu u minimalnom vremenu, nego optimalnom tehnikom produžiti toj sili vrijeme djelovanja na vodu te da broj skupina ispitanika mora biti homogenizirana i veća.

Abstract (english)

Besides physiological and technical factors, power and speed play important roles in swimming performance. The main goal of this scientific research is to define the correlation between 8 different parameters obtained with tethered swimming and t50 freestyle. The second goal of this scientific research is to develop a computer software which calculates and analyses the pull swimming force obtained by a dynamometer. By accomplishing the two mentioned goals, it can be concluded which factor impacts more swimming performance, power or technique. Measurements are obtained on 8 professional swimmers of the Croatian Academic Sports Club Mladost using dynamometric probes. The measured forces are further analysed with a computer software. The method of correlation and multiple regression analysis, from the software package Statistica, is used to determinate the correlation between different force parameters during a swimming stroke and the sprint t50 freestyle. The results of the correlation analysis show a statistically significant correlation only between t50 freestyle and ImpF (p=0.716793), while multiple regression analysis showed no significant association. Low correlation is observed on other parameters including fatInd (p = 0,309155), RDF (p = -0,553791) and Fmax / kg (p = 0,346679). From the mentioned results it can be concluded that in short competition events it is not only important to produce the maximum force in the minimum time but to also use a technique which extends that force over the time and that the sample should be homogenized and larger.
