This study aimed to investigate the independent and additive effects of counter-resistance training (RT) and soy isoflavone supplement (ISO) on bone mineral density (BMD) and bone turnover in postmenopausal women. This study used a placebo-controlled, double-blinded (soy), randomized two (ISO vs. placebo) x two (RT vs. no RT) design. Eighty sedentary postmenopausal women, aged 45-70 years, were randomly assigned to one of four groups (71 completed a 9-month intervention): RT+ISO (n=15); no RT+ISO (n=20); RT+placebo (n=18); no RT+placebo (n=18). Participants randomized to ISO received 100mg/ day/oral of soy isoflavone; and those to RT attended supervised counter-resistance training sessions at least twice a week. At baseline and 9-month, BMD was estimated by dual-energy X-ray absorptiometry (DXA). Serum levels of C-terminal cross-linked telopeptide of type I collagen (CTX), osteocalcin, and insulin-like growth factor-1 (IGF-1) were measured as bone turnover. ANOVA with time as the repeated measure and test t were used in the statistical analysis. After 9 months of intervention, neither ISO nor RT alone affected BMD at any site or levels of CTX, osteocalcin, and IGF-1 (p>0.05). ISO and RT had no additive effects on BMD and bone turnover. RT groups showed significantly increased muscle strength (+ 35.2%) (p=0.02). We found no additive effects of resistance training and soy isoflavone on bone mineral density or bone turnover in postmenopausal women after 9-months.

In This work we studied the action of calcitonin on bone regeneration in the jaws of normal and ovariectomized rats with and without administration of calcitonin. One hundred rats aged approximately sixty days were used for this study. Of these fifty were ovariectomizedOv forming group and one month after the surgery, animals in all a hundred surgical bone defect was made in the angle of the mandible, creating a bone lesion of approximately 4 mm, covered with a PTFE barrier. OvThe animals were divided into two equal groups: Ov (ovaricctomizados) and LMO (ovariectomized with calcitonin). The other fifty animals, only with the bone lesion were also divided into two groups: control (C) and CM (control with calcitonin). Treated groups received the first dose of the substance immediately after surgery, the dose of 2 IU / kg IM three times per week. The animals were sacrificed after three, seven, 14, 21 and 28 days, with their jaws removed and sent for histological preparation. Densitometric analyzes were performed histological and histomorphometric verifying that it was observed that the Ov animals showed decreased bone density and a much slower regenerative process, when compared with control animals. Calcitonin proved effective in both ovariectomized animals and in those with only bone injury.
