Introduction: Genu varum abnormality causes weaknesses in the implementation of performance tests that due to the strength related the hip abductor muscles .This study aimed was to compare the effect of two types of corrective exercises with and without foam rolling on range of motion , functional performance tests and genu varum in girl students .
Methodology: in this semi experimental study. A total of 30 girl students with genu varum abnormality with the average age of 11±0.74 years, weight 33.36±7.7 kg and height 142.18±9.5 cm purposive were selected and randomly assigned to two groups. both groups for 8 weeks and 3 days per week for 35-40 minutes each session performed corrective exercises. genu varum abnormality, range of motion and functional performance tests including" Single leg Hop for distance, 6 Meter Timed Hop and Cross Over "Measured and evaluated. for analyzed the mean difference between the groups, SPSS software independent T- test was used .
Results: No statistical significant difference was observed between two types of corrective exercises - with and without foam rolling – on range of motion, functional performance tests including "6 Meter Timed Hop and Cross Over", and genu varum abnormalities (p>0.05). But there was a significant difference between two type of corrective exercises - with and without foam rolling - on the Single leg Hop for Distance(p<0.05) .
Discussion: The comparison of averages showed that corrective exercises with foam rolling greater than impact on improve the factors of the research was to corrective exercises without foam rolling , but the difference except single leg hop for distance were not significant in other tests .
