Effect of 8-week NASM's corrective exercise continuum on correction of lumbar lordosis and some biomotor skills in female students with hyperlordosis

Consequence of incorrect body posture are investigable in physical، psychical، economical، and social aspects. So the purpose of this study was to determine the effect of 8-week NASM’s corrective exercise continuum on correction of lumbar lordosis and some biomotor skills in female students with hyperlordosis. In this quasi-experimental study، 400 students of 18 to 22 years old were selected randomly and were screened by using flexible ruler، sit-up test (strength and endurance of abdominal muscle)، sit and reach test (flexibility)، Y balance test (dynamic balance) were measured. At the end، 30 students that had more than a 30 degree lumbar lordosis angle curve were selected. Then they were randomly divided into two groups: the NASM corrective exercises and control group. The Experimental groups attended for 8 weeks، 3 times a week and 60 minutes in each session. Collected data was analyzed statiscally by using t-test for independent and for matched data. Results showed significant difference in post-tests (P<0. 05). In comparison pre and posttest NASM group had significant decrease in lumbar lordosis (P<0. 05) and significant increase in strength and endurance of stomach muscles، back flexibility and balance (P<0. 05). It can be conclouded that the NASM corrcetive exercises training protocol was effective in reducing the lumbar lordosis and increasing strength and endurance of stomach muscles، back flexibility، and balance. It is recommended to clinicians، coaches، athletic trainers and other health related specialists to do this protocol for correcting the lumbar hyperlordosis and increasing biomotor skills.
