598 The role of the Dual X-Ray Absorptiometry investigation in the design of personalized training programs for women with postmenopausal osteopenia / osteoporosis

Abstract

Osteoporosis affects many postmenopausal women and represents an economic burden. The purpose of the study was to observe the effects of a 1-year strength program on the bone mass at the level of the femur. Twenty-nine women were included in the randomized study, being divided into an exercise group (56±2.9 years old, n = 20) and a control group (56.4±2.1, n = 19). After 12 months of participation in the strength program (twice a week, using intensities of 70% of 1RM and 50% of 1RM) the exercise group showed statistically significant increases in all areas of interest of the femur as follows: femoral neck (+2.05%, p = .001,  = .45), trochanteric area (+3.80%, p < .001,  = .75), intertrochanteric area (+0.97%, p = .013,  = .37), Ward's triangle (+1.77%, p = .023,  = .24) and femur's total bone mineral density (+1.97%, p < .001,  = .51). In conclusion, alternating the intensities of 70% of a maximum repetition with those of 50% of a maximum repetition within the same set of 12 repetitions, bone mineral density at the level of the femur can undergo improvements.
