Aim: The aim of this study was to analyze the effects of the practice of a dynamic physical exercises program (DPEP) on bone mineral density (BMD) at lumbar spine region in menopausal women.
Methods: Experimental investigation at 32 weeks. The sample was divided into experimental group (EG N.=7.61+5 years), and control group (CG N.=7.60+8 years). The volunteers were submitted to gymnastics sessions (15 to 30 repetitions in muscle groups), hydrogymnastics and in self-selected rhythm, 3 times a week. BMD was measured on DXA before and after DPEP and the segments were: total spine, lumbar spine and total calcium, lean tissue, body mass index, whole body fat. In SPSS 17.0, median and IQR (interquartile range) were removed for DPEP effects; for the descriptive statistics, the Wilcoxon Explore and in the intergroup comparison of measures, the U test of Mann-Whitney. It was used the Shapiro Wilk test for distribution. It was adopted P≤0.05 and Δ% variation.
Results: There were no significant changes in BMD, but TS (total spine) Δ%+2.56%, P=0.178 and in BMD of TLS (total lumbar spine) Δ%+1.06%, P=0.611 the results were more consistent. In LT (lean tissue) of the EG (Δ%=2.39, P=0.018) and decreased 14% in the classification of osteoporosis, keeping the moderate osteopenia and normality. The CG decreased 14% in the normality, increased 14% in moderate osteopenia, keeping osteoporosis.
Conclusion: BMD increased in the (total lumbar spine) and the osteoporosis condition decreased, indicating that the dynamics of changes showed by DPEP was effective, although not significant, thus improving women’s health, specifically in bone mass.
