  Background and Objectives : Running is a basic pattern of the movement causing improvement of functional disorders of the lower limbs. The aim of this study was to determine the suitable method in running exercise (forward or backward) for improvement of the lower limb function.

  Materials and Methods: In t his interventional study, 40 healthy female subjects with the range of 18-24 years old were included. They randomely separated into two groups, forward and backward running groups. The interventional programme included two methods of running undertaken three days per week for a period of six weeks. Four types of the lower limbs functional tests Modified Romberg, Vertical Jumping, Single Leg Hop Test for Distance, and Single Leg Hop Test for Time were applied to determine the suitable method of running. The measurements were carried out as pre- and post- tests. For analysis of data, paired and independent t tests were used.

  Results: During backward running, there were statistically significant differences (p<0.05) between pre- and post- tests in all four measurement methods, and it improved the lower limb function. However, these findings were observed only in two methods of measurement during forward running (p<0.05).

  Conclusion: The results of this study indicated that the effects of backward running exercises on lower limb function tests are significantly more effective than forward running and it may improve dysfunctions of the lower limb.

  Key words : Backward running, Forward running, Lower limb function tests

  Funding: This research was founded by Semnan University of Medical Sciences.
