Introduction: The hyperlordosis is one of the most common disorders among girls and it has been cosidered to achieve an appropriate program to reduce lumbar lordosis, so the aim of this study was to compare the effect of two kinds of traditional and National Academy of Sports Medicine (NASM) corrcetive exercises training protocols on the correction of hyperlordosis in female students.Materials and Methods: In this quasi-experimental study, 400 students of 18 to 22 years old were selected randomly and were screened. At the end, 45 students that had more than a 30 degree lumbar lurdosis angle curve were selected. Then they were randomly divided into three groups: the traditional exercises, the NASM exercises a control group. The experimental groups attended for 8 weeks, 3 times a week and 60 minutes in each session. Data were analyzed by repeated measure ANOVA (P < 0.05).Results: Significant interactions were observed for 3 groups and tests (F(2, 42) = 43.3, P < 0.01). Contrasts revealed that ratings of lumbar lordisis decrease for NASM group (F(2, 42) = 95.2, P < 0.01, ES = 0.9) and traditional group (F(2, 42) = 17.2, P < 0.01, ES = 0.7) Were significantly higher than control group.Conclusion: It can be conclouded that the NASM corrcetive exercises training protocol was more effective in reducing the lumbar lordosis and it is recommended to clinicians, coaches, athletic trainers and other health related specialists to do this protocol for correcting the lumbar hyperlordosis.
