High and Low Impact Physical Activity Positively Influences Female Bone Density

Objective. The aim of the current study was to add to the current literature the effects of high and low impact physical activity on female bone health. Background. Exploring lower cost preventative measures to improve bone density may reduce the physical and financial repercussions associated with health risks such as osteoporosis. Methods. Fifty-four female athletes total bone mineral density was tested using a dual-energy x-ray absorptiometry (DEXA) machine. Athletes were defined as either high intensity (HI) or low intensity (LI) based on training mode. Results. There was not a significant difference between groups in bone mineral density for HI females (M=1.25, SD=0.10) and LI females (M=1.22, SD=0.11); t(51) = -1.057, p=.295. Conclusion. Females that regularly take part in either high or low intensity activities may benefit from having improved bone mineral density.
