Abstract: Prediction and prevention of bone fractures is considered as one of the most important challenges of the worlds health systems. The aim of this study was to evaluate the effect of 16 weeks endurance training on biomechanical and geometrically parameters of the femur and tibia bones in adult male Wistar rats. The 16 rats with an age range of 50-60 days and an average weight of 160±10 g were randomly divided into two groups: training (progressive running protocol for 16 weeks at a speed of 18-36 m in minute for 20-60 min, 5 days a week) and control group (no activity). A day after the end of the training, the rats were sacrificed, the right femur and tibia bones were harvested, then by mechanical three-point bending test, the biomechanical parameters (stiffness, maximum mechanical strength and maximum energy to the point of maximum strength) and by digital caliper, geometric parameters (length and width) were measured. One way-ANOVA was used to compare biomechanical and geometrical parameters between groups (p≤0/05). The results demonstrated a significant increase in biomechanical parameters (stiffness (the femur and tibia), maximum mechanical strength (in the femur)) and geometric parameters (length (the tibia)) after 16 weeks endurance training. The 16 weeks of endurance training (used in this study) can be used to prevent fractures and osteoporosis and osteomalacia with improved biomechanical and geometry parameters used in the femur and tibia bones.
