SažetakUvod/Cilj. Fizička aktivnost ima anaboličko dejstvo na koštano tkivo. Međutim, još uvek nije potpuno jasno kakav je uticaj intenzivne fizičke aktivnosti tokom detinjstva, a posebno u prepubertetskom uzrastu. U cilju utvrđivanja uticaja vežbanja na telesnu građu i gustinu kosti kod dece koja se aktivno bave sportom, ispitali smo grupu dečaka prepubertetskog uzrasta koji treniraju fudbal, kao i grupu dečaka prepubertetskog uzrasta koji se ne bave sportom aktivno u početnoj fazi dostizanja maksimalne mase kosti. Metode. Uzorak ispitanika sastojao se od 62 dečaka prepubertetskog uzrasta, podeljenih u dve grupe: grupu od 32 dečaka, uzrasta 10,7 ± 0,5 godina, koji aktivno treniraju fudbal najmanje godinu dana (10-15 sati nedeljno) i kontrolnu grupu od 30 dečaka, uzrasta 11,2 ± 0,7 godina, koji se ne bave aktivno sportom, osim fizičke aktivnosti tokom redovne nastave u školi u trajanju od 1,5 sat nedeljno. Telesna građa procenjena je primenom uređaja Body Fat Analyser BES 200 Z, dok je gustina leve i desne petne kosti procenjena pomoću ultrazvučnog denzitometra Sahara (Hologic, Inc, MA, USA). Rezultati. Dobijeni rezultati pokazali su da postoji statistički značajna razlika između dečaka koji aktivno treniraju fudbal i kontrolne grupe u količini masnog tkiva (p = 0,01), kao i gustini obe petne kosti (p = 0,01). Zaključak. Rezultati ovog istraživanja potvrđuju značajne efekte fizičke aktivnosti na smanjenje telesne mase i povećanje gustine kostiju. S obzirom na to da je veoma lako ostvariti vežbanje fudbala u široj populaciji dece i mladih, što ne važi za mnoge druge sportove, treba ga što više koristiti u prevenciji gojaznosti i osteoporoze.
