Influence of certain motor abilities on ball throwing velocity in Goalball: A pilot study

Abstract

The aim of the research was to determine the influence of sprint performance and explosive strength on ball throwing velocity in Goalball. The sample of participants consisted of 12 nationally and internationally ranked Goalball players, with an average age of (25.17±8.03). To evaluate sprint performance, the 5 and 10 meter sprint tests were used. To evaluate explosive strength, the standing long jump and seated medicine ball throw were used. The results of the regression analysis have indicated that the entire system of applied variables is statistically significantly connected and influences ball throwing velocity. At the same time, we evaluated the statistically significant influence of the seated medicine ball throw variable. We can conclude that as part of the fitness training of Goalball players, it is necessary to work on improving sprint performance and explosive strength due to the ability of rapid transition of the players from the defensive phase to the attack phase. It is especially important to develop upper-body explosive strength in order to increase ball throwing velocity and create the possibility for greater effectiveness of Goalball players.

Cilj istraživanja je bio da se utvrdi uticaj brzine i eksplozivne snage na brzinu bacanja lopte u Golbalu. Uzorak ispitanika je činilo 12 golbalista prosečne starosti (25.17±8.03) godina nacionalnog i međunarodnog ranga. Za procenu brzine korišćeni su testovi trčanja na 5 i 10 metara. Za procenu eksplozivne snage korišćeni su testovi skok u dalj iz mesta i bacanje medicinke iz sedećeg položaja. Rezultati regresione analize pokazali su da ceo sitem primenjenih varijabli ima statistički značajnu povezanost i uticaj na brzinu bacanja lopte. Pojedinačno posmatrano statistički značajan uticaj ima varijabla bacanje medicinke iz sedećeg položaja. Može se zaključiti da je u okviru kondicione pripreme golbalista potrebno raditi na razvoju brzine i eksplozivne snage zbog sposobnosti brzog prelaska igrača iz faze odbrane u fazu napada. Posebno je bitno razvijati eksplozivnu snagu mišića ruku i ramenog pojasa kako bi se povećala brzina bacanja lopte i stvorila mogućnost za veću efikasnost Golbal igrača.
