Effectiveness of Corrective Exercises Based the National Academy of Sports Medicine’s Protocol in Correcting Flexible Flatfoot and Postural Control in Male High School Students With Overweight

 Flatfoot and postural control problems are the most common physical and motor disorders among shool students. This study aims to investigate the effects of the National Academy of Sports Medicine (NASM)’s corrective exercises on the correction of flexible flatfoot and postural control in male high school students with overweight.

 This is a quasi-experimental study with a pre-test/post-test design. Participants were 40 male high school students with flexible flatfoot and overweight who were selected using a purposeful sampling method and were randomly assigned into two groups of exercise (n=20) and control (n=20). The exercise group performed NASM’s corrective exercises for 8 weeks, three sessions per week, each for 45 minutes. Variables were measured at the baseline and after the program. Data were analyzed using analysis of covariance in SPSS software, version 24. The significance level was set at 0.05.

 The NASM’s corrective exercises could significantly improve flexible flatfoot and postural control in overweight students (p≥0.05). The effect size was 0.32 for the flatfoot and 0.28 for the postural control variables.

 The NASM’s corrective exercise protocol can correct the flexible flatfoot and improve postural control in male high school students with overweight. Therefore, it is recommended that trainers and rehabilitation centers use this corrective exercise protocol.
