Background and Aims

Regular exercise and physical activity is one way to promote health and prevent physical and mental diseases. The aim of this study was to investigate the effect of endurance training on positive and negative slopes (ETPS and ETNS) (±15°) on the biomechanical properties of the femur in male Wistar rats.

Materials and Methods

This experimental study was performed on 15 male Wistar rats with an approximate age of eight weeks and a weight range of 20-180 g. For this purpose, the rats were divided into 3 groups, namely the control group (without activity), the ETPS group and the ETNS group. The endurance training (ET) program was performed 5 days a week for 8 weeks.


Significant improvement in biomechanical variables (maximum force, strength, deformation and maximum absorbed energy) of the femur was observed in the ETPS group compared with the other two groups. However, the ETNS reduced all biomechanical variables of the femur.


The results indicate that ETPS is effective in improving the bone indices. Given the significant difference between the ETPS and ETNS groups in the biomechanical parameters of the bone, a training program with different intensity and duration levels in other age groups in different slopes is suggested.
