The Comparison of Bone Mineral Density in Upper and Lower Body between Professional Female Footsal Players and Non-Athletes

Background: The purpose of this study was to compare the bone mineral den sity (BMO) of the upper and lower body between professional female foot sal players and non-athlete females. Methods: Fifteen professional female footsal players (age: 24.3 ± 2.8 years , height: 161.1 ± 4.4 ern, weight: 54.3 ± 7 .0 kg) and 15 healthy nonathlete females (age: 23.8 ± 2.0 years, height: 160 .9 ± 7 .0 ern, weight: 51.5 ± 9.6 kg) participated in this study. BMO was measured by Dual Energy X-Ray Ab sorptiometry (OEXA) at the lumbar spines and femoral neck, femoral trochanter of both legs. Findings: In footsal players BMO values were found to be significan tly higher at the whole body, lower and upper body compared with non-athletes. BMO of footsal players in upper and lower body was 1269.1 and 1161.0 mg/crrrʹ re spectively. These values for non-athletes were 1102.4 and 877.7 mg/crnʹʹ re spectively. The difference between these sites in both groups was statistically significant (P < 0.0 J.). When the BMO values of the footsal players were compared with non-athletes, we found that the BMO gain in the lower body of the footsal players relative to the non-athletes was twice as much as the upper body of footsal players compared to the non-athletes. Conclusion: It seems that weight bearing and high impact loads are the most important factors to improve the BMO in lower body. The bones of lower body are subjected to multidirectional, dynamic compressive, and sheer forces during foot sal activities such as the struts, jumping, landing, cutting and running. Therefore, it can be concluded that the BMO of the lower body were benefited more than upper body in footsal players.
