Analiza rezultatov dinamometrije mladih teniških igralcev in igralk z vidika tekmovalne uspešnosti : diplomsko delo

Dobnikar, Nal (author), Filipčič, Aleš (mentor)

Tenis je šport, pri katerem je dominantna stran telesa bolj obremenjena kot druga. Večje razlike med stranema telesa vodijo v poškodbe, zato je najboljša preventiva športna diagnostika, v katero spada metoda dinamometrije. Namen diplomskega dela je bil ugotoviti vpliv rezultatov dinamometrije na tekmovalno uspešnost mladih igralk in igralcev Slovenije. V vzorec je bilo zajetih 88 igralk in igralcev, starih od 11 do 16 let, ki so redno trenirali in tekmovali pod okriljem Teniške zveze Slovenije ter bili na širšem spisku za izbor reprezentantov in reprezentantk Teniške zveze Slovenije. Na vsakoletnem rednem testiranju oktobra 2016 so opravili teste dinamometrije z ročnim dinamometrom. Izmerjena je bila največja sila prijema dominantne ter nedominantne roke ter povprečna sila prijema v 20 sekundah dominantne ter nedominantne roke. Testirance smo razvrstili po spolu in starosti v tri kategorije, do 12, 14 in 16 let. Podatke smo obdelali s statističnim programom SPSS 19.0 ter Microsoft Excel 2013. Za vsako posamezno kategorijo smo izračunali aritmetično sredino in standardni odklon ter s korelacijskim testom in Spermanovim koeficientom preverili povezanost med spremenljivkami. Za preverjanje hipotez smo uporabili 5- odstotno stopnjo tveganja. Želeli smo ugotoviti, ali obstajajo statistično značilne razlike med kategorijami, ki vplivajo na tekmovalno uspešnost, ki smo jo preverjali s končno lestvico TZS iz leta 2016. Ugotovili smo, da ni povezanosti med največjo silo prijema ter mestom na lestvici TZS. Rezultati kažejo, da so igralci z manjšimi razlikami med dominantno in nedominantno stranjo rezultatsko slabši in zasedajo nižja mesta na lestvicah. V kategoriji do 16 let ima vodilni igralec tudi največje vrednosti dinamometrije, kar kaže na pospešen telesni razvoj.

• Title: Analysis of results of dynamometry in young male and female tennis players in connection with the competition performance

Abstract

Tennis is sport where the dominant side of the body is more loaded than the other. Major differences between the sides of the body lead to injuries. Therefore, the best prevention is sports diagnostics which include the method of dynamometry. The purpose of the study was to determine the impact of the results of dynamometry on the competitive performance of young Slovenian tennis players. The sample consisted of 88 players from 11 to 16 years of age who were regularly training and competing in tournaments organized by Tennis Slovenian Association and were on the broader list for the selection of national team representatives in the Tennis Slovenian Association. The dynamometer tests with manual dynamometer were performed at the annual regular testing in October 2016. The maximal force of the grip of the dominant and non-dominant was measured and the average force of the grip produced in 20 seconds of the dominant and non-dominant arm was measured. The players were classified by gender in the age group into three categories, up to 12, 14 and 16 years. Data were processed with the statistical program SPSS 19.0 and Microsoft Excel 2013. The arithmetic mean and standard deviation was calculated for each individual category. Then the correlation test was run and the results were checked with Sperman’s rank correlation coefficient which checked the relationship between the variables. For the verification of hypothesis we used a 5% level of risk. We wanted to determine whether there are statistically significant differences between the categories that influence the competitive performance that we checked with the final rankings of the 2016 season. We found that there is no correlation between the highest grip force and the place on the rankings. The results show that players with minor differences between the dominant and the non-dominant side are worse and occupy lower rankings. In the category of up to 16 years the leading player has the highest values of dynamometry which indicates greater physical development.
