Sažetak

Fizička aktivnost ima pozitivan uticaj na koštano tkivo. U cilju utvrđivanja uticaja odskočne noge na koštani mineralni sadržaj izmereni su dečaci i devojčice prepubertetskog uzrasta koji se aktivno bave sportom, a nalaze se u početnoj fazi dostizanja maksimalne mase kosti. Uzorak od 60 ispitanika sastojao se od 32 fudbalera (dečaka, 10.7±0.5 godina, Mean±St.dev.) i 28 plivača (15 devojčica i 13 dečaka, 10.8±0.8 godina, Mean±St.dev.), koji se aktivno bave izabranim sportom u trajanju od najmanje godinu dana (fudbaleri 10- 15, a plivači 8-12 sati nedeljno). Uzorak ispitanika je podeljen na grupu, koju je sačinjavalo 40 ispitanika, sa odskočnom levom nogom i grupu koju je sačinjavalo 20 ispitanika, sa odskočnom desnom nogom. Koštano mineralna gustina (BMD) leve i desne petne kosti procenjena je pomoću ultrasonografskog denzitometra 'Sahara' (Hologic, Inc., MA, USA). Nisu utvrđene značajne razlike između grupa u odnosu na varijable denziteta kosti 1) brzinu zvučnog signala (speed of sound - SOS) i 2) slabljenje zvučnog signala (broadband ultrasound attenuation - BUA). Srednja vrednost varijable SOS, odskočne leve i odskočne desne noge se razlikuju, ali ta razlika nije značajna (p>0.05). Srednja vrednost varijable BUA, odskočne leve i odskočne desne noge se razlikuju, ali ta razlika nije značajna (p>0.05). Rezultati istraživanja ne ukazuju na to da odskočna noga utiče na koštani mineralni denzitet petne kosti.
