The effect of eight weeks of functional training on static and dynamic body posture and psychosocial quality of life of high school students

Introduction: The present study aimed to investigate the effect of an eight-week functional training program on static and dynamic body posture and psychosocial quality of life of high school students. Methodology: The present study was a quasi-experimental study with a pre-test-post-test design with a control group. The statistical population of the present study included all male high school students of Shahid Ba'akhlaq School in Tabadkan District, Mashhad in the academic year ۱۴۰۳-۱۴۰۴, totaling ۲۵۰ people. Sampling was carried out by convenience and voluntary method, and ۳۰ people were selected from among the eligible volunteers and randomly divided into two groups of ۱۵ people (experimental and control). To collect data, the KidScreen Health-Related Quality of Life Questionnaire (۲۰۰۴), the New York Test for assessing static body posture (Hawley and Franks, ۱۹۹۲), and the Functional Movement Scale (FMS) for assessing dynamic posture and basic movement patterns were used. The experimental group underwent a functional training program for eight weeks, three sessions per week, while the control group continued their usual activities. SPSS software was used for analysis. In the descriptive statistics section, mean, standard deviation, and frequency tables were used to describe the variables. In the inferential statistics section, the multivariate ANCOVA test was used in the experimental and control groups to control the pre-test and examine the effect of the functional training program. Findings: The results showed that eight weeks of functional training had an effect on static and dynamic body posture and psychosocial quality of life of high school students. Conclusion: This study showed that eight weeks of functional training significantly improved students' ability to maintain static body posture, motor coordination in dynamic situations, and experience psychosocial quality of life. These effects could be due to a combination of neuromuscular adaptations, strengthening motor chains, increased body awareness, and experiencing group interactions and receiving continuous feedback.
