Vpliv 10-tedenskega treninga prostih metov na obroč z zmanjšanjim premerom pri mladih košarkarjih : diplomsko delo

Trafela, Anže (author), Erčulj, Frane (mentor)

Met v košarki predstavlja element, ki se med igro najbolj pogosto pojavlja. Z uspešnim metom si ekipa prisluži točke. Prosti met je v košarki edini met, pri katerem ima igralec na voljo vedno enake igralne pogoje. Čeprav je uspešen prosti met vreden le eno točko, pogostokrat ravno prosti meti odločajo končnice tekem. Zavedamo se pomembnosti učinkovitega izvajanja prostih metov, zato smo izvedli raziskavo, kjer nas je zanimalo, kako 10-tedenski trening prostih metov na koš s specialnim (zmanjšanim) obročem vpliva na vpadni kot in uspešnost izvajanja prostih metov. V raziskavo smo vključili 11 igralcev KD Slovan, starih od 15 do 17 let. Razpon višine igralcev je bil od 180 do 200 cm. V raziskavi je vsak igralec opravil najprej 10 treningov meta na običajen obroč. Na vsakem treningu so igralci izvajali proste mete v petih serijah po 20, 25, 30, 35 in 40 metov. Po končanih 10 treningih na običajen obroč so igralci opravili še 20 treningov po enakem principu na obroč z zmanjšanim premerom. Med samimi treningi smo opravili tudi testiranja metov. Na testiranjih smo uporabili t. i. ''pametno žogo'' ali ''smart basketball''. Pametna žoga je v bistvu prejemnik sil, s katerim košarkar deluje na košarkarsko žogo pri vodenju ali metih na koš. Tako smo lahko spremljali napredek košarkarjev med samo raziskavo. Postavljene hipoteze lahko zavrnemo, saj se je izkazalo, da obroč z zmanjšanim premerom nima vpliva na povečanje vpadnega kota niti na uspešnost meta na treningih ali tekmah. Trening meta na običajen obroč ima, po rezultatih sodeč, podoben učinek kot trening meta na obroč z zmanjšanim premerom. Tudi učinek samega treninga se je ohranil manj časa, kot smo predvidevali pred začetkom raziskave.

• Title: Effect of a 10-week training programme with a reduced hoop diameter rim on free-throw performance in young basketball players

Abstract

There are a lot of elements in basketball game and basketball shot is the most used element of all. With every successful shot team is rewarded with points. Free-throw is only shot in basketball game where are playing conditions the same every time we shot it. Free-throw is very important element of basketball game thus is worth only one point. A lot of games are decided by free-throw shots, especially at the end of the game. 11 players from KD Slovan, aged from 15 to 17, participated in this research. Each one of the participants performed 10 practices of free-throw shooting with series of 20, 25, 30, 35 and 40 shoots on regular rim. In second part of research all participants performed 20 practices of free-throw shooting on reduced hoop diameter rim with exact number of shoots. Meanwhile participants were tested several times during research with 94Fifty technology (smart ball). Smart ball is a regulation basketball with sensors inside. Those sensors measure shot and dribbling, and send the data over Bluetooth to smart-phone or computer. All data from practices and testing days were collected with special designed formulars. With 94Fifty technology we could follow progress during research. We found that a reduced hoop diameter rim makes no significant difference in 10-week training program. Effects of a reduced hoop diameter rim were short term and shorter than we expected.
