Effect of football or volleyball on bone mineral density in different body segments among male college students / 中国学校卫生

ABSTRACT

Objective@#To explore the effect of football or volleyball on bone mineral density of male college students, and to explore possible region specificity, imbalance and asymmetry.@*Methods@#The bone mineral density of upper and lower limbs, hip and whole body were measured in 42 college football players, 54 volleyball players and 100 typical college students.@*Results@#The BMD among football players and volleyball players was significantly higher than that of typical college students(P<0.05). The BMD in the upper limbs of volleyball players was significantly higher than that of football players and typical college students(P<0.05). BMD in the lower limbs of football players was significantly higher than that of volleyball players and typical college students(P<0.05). BMD in the right lower extremity of the football players was significantly higher than that of the left(P<0.05), while that of the right upper limbs of the volleyball players was significantly higher than that of the left(P<0.05).@*Conclusion@#Football or volleyball sports can improve bone mineral density among male college students, however, the effects show region specificity, imbalance and directional asymmetry, which might be related to the mechanical stimulation of bone.
