The Effect of Eight Weeks strength Training on some selected Biomechanical Properties of Femur of Old Male Rat

The purpose of this study was to determine the effect of eight weeks strength training on some chosen biomechanical properties of femur of old male rats.
in this experimental research sixteen old male Wistar rats with Twenty months old were assigned to sedentary control group (n=8) and strength training group (n=8). strength training group climbed from a ladder for 8 weeks, 4 times per week. Forty eight hours after last session of exercise training, animals were anesthetized and femur bones were removed. Three – point bending test was used to determine bone biomechanical properties. Our data was analyzed by independent t test (p≥0/05).
the results showed this training had no significant effect on bone stiffness, fracture energy and maximal load.
the probable cause of this object can be intensity, type and time of training or age of activity beginning .
