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. CR - 1.
