A total  of 37 prepubertal girls participated in this study. Subjects were divided into two groups: Volleyball  (ages=13.2±0.8 years, n=17) and control (ages=12.62±0.91 years, n=20 ). Children in volleyball  groups has been training regularly for 10-12 hours a week for 3-4 years. Children in control group has  not been participating in regular exercise training. Dominant and non-dominant leg BUA (Broadband  Ultrasonographic Assesessment) values were taken from calcaneus by QUS-2 (Metra Biosystems). Three  days milk and dairy products records were obtained from each subject. Food records were analysed by  BEBIS food analysing programme and daily calcium intake of the subjects were calculated. Student t-test  statistical method was used to compare two groups. Volleyball players’ BUA (dom= 75.9 ± 7.1, nondom=  76.26 ± 7.2) and t-score values were significantly (p<0.05) higher than those of non-exercising  group (BUA: dom=68.18 ± 8.5, non-dom = 67.12 ± 8.4). In conclusion, volleyball training, which has  been regarded as weight bearing and high impact sport, has benefical effeects on bone mineral density in  prepubertal girls. }, number={3}, publisher={Gazi University}
