The aim of the present study was to evaluate the effects of an AAG on BMD, osteocalcin and functional autonomy in older women. The sample consisted of eighty-two post-menopausal women with low BMD, randomly divided into two groups: the Aquatic Aerobics Group [AAG; n = 42; age: 66.8 ± 4.2 years], submitted to two weekly sessions over eight months, and the Control Group (GC; n = 42; age: 66.9 ± 3.2 years), which did not participate in regular exercise. BMD was measured by Dual Energy X-ray Absorptiometry [DXA] of the lumbar and femur, and serum osteocalcin was measured using electrochemiluminescence. A functional autonomy assessment protocol (GDLAM, 2004) was also applied. Statistical analyses used were repeated measures ANOVA and Tukey's post hoc tests. The results showed a significant improvement in tests following the GDLAM protocol: 10 meters walk (10 mw) – p = 0.003; rising from a ventral decubitus position (RVDP) – Δ% = 0.78, p < 0.001; rising from a chair and moving around the house (RCMH) – p < 0.001 and autonomy index (AI) – p = 0.007, with more favorable results observed in the AAG when compared to the CG. The AAG achieved the best results for BMD; however, no inter or intragroup statistical differences were recorded for total femur – p = 0.975 and lumbar L2–L4p = 0.597. For serum osteocalcin, intra and intergroup statistical differences of p = 0.042 and p = 0.027 were observed in the AAG, respectively. This demonstrates that an eight-month aquatic aerobic exercise program can improve functional autonomy and osteocalcin levels, although training did not improve lumbar and total femur BMD in the older women.
