Journal of North Khorasan University of Medical Sciences Spring 2014;6(1):69 Comparison of Bone Mineral Density and Bone Mineral Content of femur in physical educating and non physical education students

The aim of current study was the comparison of Bone Mineral Density (BMD) and Bone Mineral Content (BMC) of femur in physical educating and non-physical education students at universities of Bojnurd. Methods and materials: Fifteen physical educating (age: 22/33 ± 2/22 years) and Fifteen non-physical education students (age: 23/40 ± 1/29 years) from the different Bojnurd Universities participated in this study. Subjects were randomly selected in each group. BMD and BMC of femur measured using a Dual- Energy X-ray Absorptiometry (DEXA) system. SPSS software used to analyze data. Independent T test used to compare BMD and BMC between two groups. The significant level set at p≤ 0.05 for all statistical procedures. Data were normalized using kolmoghrov and Smirnoff test. The result of the current study showed that BMD and BMC, T- Score and Z- Score at different locations of the femur in physical education students were higher than non-physical education students. However this difference was not statistically significant. It seems that the practical courses for physical education student were not intensity enough to increase BMD and BMC in bone.
