Background: Rapid modern world changes have impacted efforts to educate children with abilities and skills suitable for societal goals. Aims: The aim of the study was to investigate the effects of active video games and selected movement games on children’s physical literacy and self-concept. Materials and Methods: Sixty 8-12-year-old children from Ahvaz City were selected and assigned into three experimental and one control groups. Physical literacy and self-concept were assessed in pretest. The active video game group played Xbox Kinect bowling, athletics, tennis, soccer, volleyball, basketball games. The selected movement game group played researcher-designed games. The mixed game group engaged in both activities over 12 video and 12 movement game sessions for 8 weeks, with 30-minute per session. Data were analyzed by MANOVA and student t-test. Results: The results showed that active video games and selected movement games influenced children’s physical literacy and self-concept. Further, significant differences were found between the experimental groups' physical literacy and self-concept outcomes. The selected movement game and mixed game groups performed better in these measures than other groups. Conclusion: Results suggest parents and teachers consider implementing the selected movement games and active video games to bolster physical literacy and self-concept in children.

Background: The modern increase in mechanical and sedentary lifestyles has led to a rise in musculoskeletal abnormalities within society. These physical irregularities may influence individual mental health.Aim: This study explores the correlation between upper body musculoskeletal abnormalities and mental health among female students at Payame Noor University, Bushehr.Material and Methods: A total of 173 female students were selected via convenience sampling for this cross-sectional study. The presence of scoliosis, forward head posture, kyphosis, and increased lordosis was assessed using a flexible ruler, the New York Test, a chessboard, and a scoliometer. Body mass index (BMI) and waist-to-hip ratio (WHR) were also measured. Participants completed the General Health Questionnaire (GHQ-28). Statistical analysis was conducted using one-sample t-tests and Pearson’s correlation coefficient, with a significance threshold set at P< 0.05.Results: The findings indicated that lordosis was significantly more prevalent among students aged 15 to 24 (t=31.5, P= 0.001) and those aged 25 and above (t=57.3, P= 0.003), compared to societal norms. Other assessed abnormalities were within normal ranges. Mental health vulnerabilities were noted in specific domains; however, no significant correlation was found between mental health status and the physical abnormalities studied.Conclusion: While lordosis was notably more common among the study's participants than in the general population, the incidence of other musculoskeletal abnormalities aligned with societal averages. No substantial impact of these physical conditions on mental health was observed. It is advisable to integrate educational initiatives and corrective exercise programs into the curriculum for educators, coaches, and students to promote overall well-being.

Purpose: This study aimed to investigate the influence of genetic polymorphisms and metabolomic profiles on physiological adaptations to a 6-week High-Intensity Interval Training (HIIT) program in individuals with moderate fitness levels, addressing the variability in exercise response. Method: Thirty moderately fit adults participated in a supervised 6-week HIIT intervention. Pre- and post-training assessments included VO2max, lactate threshold, genetic profiling of key polymorphisms (e.g., PPARGC1A rs8192678) using PCR and next-generation sequencing, and untargeted metabolomic analysis via liquid chromatography-mass spectrometry (LC-MS). Statistical analyses involved paired t-tests, multivariate regression, principal component analysis (PCA), and partial least squares discriminant analysis (PLS-DA). Results: Significant improvements were observed in VO2max (p < 0.001) and lactate threshold (p = 0.004). Carriers of the PPARGC1A G allele showed greater aerobic capacity gains, accompanied by upregulation of PGC-1α expression. Metabolomic profiling revealed significant shifts in glucose and lipid metabolism pathways post-HIIT. Multivariate models identified interactions between genetic variants and metabolomic changes that predicted individual training responsiveness. Conclusion: Integrating genetic and metabolomic data enhances understanding of individual variability in HIIT adaptations and supports the development of personalized exercise prescriptions to optimize health and performance outcomes.
