Sažetak

Uprkos nekadašnjem mišljenju da je trening za razvoj mišićne snage kod dece neefikasan i sa potencijalnim negativnim efektima, danas sportske organizacije i udruženja podržavaju učestvovanje dece u adekvatnim i pravilno osmišljenim programima za razvoj snage. Ipak, ostaje određena bojazan da bi trening snage mogao da ima negativan uticaj na koordinaciju kod mladih sportista. Za potrebe ovog istraživanja sastavljen je program za razvoj snage od vežbi koje su u svojoj osnovi sadržale ciklus skraćivanja i izduživanja. Trening koji se sastoji od pomenutih vežbi deluje na mišićnotetivne i neurološke činioce koji utiču na ukupnu ispoljenu snagu sportiste. Cilj istraživanja je utvrđivanje navedenog tipa treninga na koordinaciju kod mladih sportista. Koordinacija je predstavljena i analizirana kroz biomehaničke parametre košarkaške tehnike. Dobijeni rezultati pokazuju da trening za razvoj snage nije negativno uticao na koordinaciju, odnosno na izabranu sportsku tehniku. Trening za razvoj snage nije narušio koordinaciju preciznih mišićnih pokreta, ali je doveo do poboljšanja maksimalne izometrijske sile (F max) zabeležene tokom maksimalne voljne mišićne kontrakcije. Testom za mišiće ekstenzore nogu (LEG test) zabeleženo je povećanje snage od 12% (177,95kg ± 60,55 pre vs. 201,9kg±62,27 post), dok je testom mišića potkolenice (CALF test) zabeleženo povećanje snage od 7% (112,48kg±26,24 pre vs. 120,81kg±22,48 post).
