| Summary: | 0.01% calcium. The IL group had the same treatment as the and calcium-deficient diet ( I group) decreased cortical BNM and ultimate load (r=0.754) and BMD and stiffness (r=0.793). and ultimate load by three-point bending to failure, cross- ANOVA. When results were found to be significant, Student BMD was only 2.37o lower than the control group mean, and by 12%, ultimate load by 19@o and stiffness by 19.77o, when cause a decrease in strength and bone mineral loss, and chow containing 1.85% calcium. The I group had one hindlimb compared to control rats.2. External loading at 34N, 36 cycles @ 2 Hz, three times per week attenuates the decrease density (BMD) by dual energy X-ray absorptiometry, stiffness exercise is known to strengthen bone. The purpose of this functional properties in this model. Immobilization and calcium-deficiency have been documented to immobilized (I) group or an immobilized-loaded (IL) group. immobilized by taping and fed a low calcium diet containing immobilized group but had the immobilized limb mechanically in BMD and ultimate load in this model. The IL group mean loaded by a unique four-point loading machine three times per modulus of elasticity. All comparisons were done by one-way Newman-Keuls Method post hoc tests when performed. Final parameters of bone mass and bone strength in bone subjected results indicate: 1. Six weeks of immobilization by taping sacrificed, both tibia removed and tested for bone mineral sectional moment of inertia, cross-sectional area, and study was to determine the effects of mechanical loading on The C group had no immobilization and were fed a regular rat This indicates BNM is an effective predictor of bone this model significant correlations were found between BMD to immobilization and calcium-deficiency. Adult female rats ultimate load was 107o lower than the control group. 3. In week. After six weeks of treatment, all animals were were randomly assigned to either a control group (C), |
