IMMEDIATE EFFECTS OF MAXIMAL STRENGTH TRAINING ON STATIC BALANCE

The aim of this study was to determine effect maximal strength training on static balance. Eleven Croatian championship rugby players (mean+ or -SD: age, height and weight 22.5 + or - 2.7 years, 182.5 + or - 6.2 cm, and 92.9 + or - 9.5 kg, respectively) volunteered in this study. Players were tested for Transversal both feet standing on balance board with open eyes, Parallel one leg stand on board with open eyes, Perpendicular one leg standing on board with open eyes. Results of this study generally showed that there were no statistical significant differences in results of static balance before and after Maximal Strength Training (MST) (p = 0.32). But, we found that there was statistical significant difference on Transversal both feet standing on balance board (p=0.03). Other two tests showed increasing results on their dominant leg in contrast to the results of non-dominant leg but not statistically significant (p > 0.05). In majority of sports most of the training time is spend on strength and power development, coaches should know that with developing strength and power they affect other abilities in this case balance. This is important practical information for sport coaches because of a lack of time, especially in in-season period.Original Abstract: Cilj ovog rada bio je utvrdivanje efekata treninga maksimalne snage na staticku ravnotezu. Jedanaest hrvatskih prvaka u ragbiju (prosjek+ or -SD: uzrasta, visine, tezine 22.5 + or -2.7 years, 182.5 + or - 6.2 cm, i 92.9 plus or minus 9.5 kg, respektivno) dragovoljno je sudjeovalo u istrazivanju. Igraci su testirani u polozajima: Transverzalno stajanje na obje noge na "balans ploci" otvorenih ociju, Paralelno stajanje na ploci otvorenih ociju i Okomito stajanje na jednoj nozi na ploci otvorenih ociju. Rezultati istrazivanja opcenito pokazuju da nema statisticki znacajnih razlika u rezultatima staticke ravnoteze prije i poslije Maksimalnog treninga snage (p = 0.32). Ali, pronadene su statisticki znacajne razlike kod transverzalnog stajanja (p = 0.03). Ostala dva testa pokazala su poboljsanje rezultata kod dominantne noge u odnosu na nedominantnu, ali rezultat niej bio statisticki znacajan (p > 0.05). U vecini sportova vecina trenaznog vremena iskoristi se za razvoj snage i sile, treneri bi trebali znati da razvojem snage zadiru i u druge sposobnsoti, u ovom slucaju u ravnotezu. To je vazna informacija za praksu i sportske trenere zbog optimizacije vremena, posebno u natjecateljskoj sezoni.
