Our first two-year period of funding focused on using the meta-analytic approach to examine the effects of exercise on BMD in adult humans using summary means from completed studies. Since no meta-analysis had existed using individual patient data IPD to examine the effects of exercise on BMD, our second two-year period of funding was devoted to examining the feasibility of such. The major conclusions from this work are as follows 1 site-specific, weight bearing exercise appears to increase andor maintain BMD anywhere from 1 to 3 in both men and women, 2 when conducting meta-analytic research, either the original metric or standardized effect size can be used when analyzing data dealing with the effects of exercise on BMD in adults, 3 Given the poor response rate in the retrieval of IPD, the use of summary means meta-analyses may be more appropriate for studies dealing with the effects of exercise on BMD in adults, 4 Adherence to the recent recommendations from the American College of Sports Medicine regarding physical activity and bone health should bring about the 1 to 3 benefit observed in our meta-analytic work.
