The aim of the present study was to examine the effect of a seven months program of water exercise, on bone mineral density (BMD) in postmenopausal women.
DEXA test findings for vertebrae L2-L4 showed that although the time factor had a significant effect only on the bone mineral content (BMC), (4.61 P < 0.05), the interaction of time group was found to be significant for each of the variables: BMD (9.25 P < 0.01), BMC (7.99 P < 0.01), z-score (5.35 P < 0.05) and t-score (9.41 P < 0.01).
DEXA test findings for femoral neck density indicated no significant differences between the groups pre and post treatment.
However a significant interaction was found for BMC (8.08 P < 0.01) in the right leg indicating an increase trend in BMC in the experimental group and a trend towards decrease for the control group.
