Background: Hyper kyphosis is a common postural issue that affects many women, often leading to negative body image. Aim: The purpose of this research was to investigate the impact of an 8-week corrective exercise program on the body image of women with hyper kyphosis. Materials and Methods: The research method used in this study was quasi-experimental. The study population consisted of female students aged 18 to 26 years with hyper kyphosis at Shahid Rajaee University. Participants were randomly assigned to either the experimental group (n=20) or the control group (n=20). Hyper kyphosis was measured using a flexible ruler, while body image was assessed using the Body-esteem Scale for Adolescents and Adults. The questionnaire had a reliability coefficient of 0.83 as measured by Cronbach's alpha. After 8 weeks of corrective exercise, both the experimental and control groups completed the questionnaire again. The control group did not receive any training during this time. The data were analyzed using the mixed ANOVA method with SPSS-26 software at a significance level of 95%. Results: The results of the mixed ANOVA analysis showed that the main effect of the training group and the interaction between the group and test stages were significant in the post-test stage for the dependent variable of total body image (F=6.82, P =0.013), appearance (F=6.72, P =0.014), attitude (F=8.81, P =0.005), and kyphosis angle (F=18.91, P =0.000). However, there was no significant effect of training on weight satisfaction. Conclusion: The results of this study indicate that eight weeks of corrective exercise significantly reduced the hyper kyphosis angle ( P =0.01), resulting in an improvement in the subjects' posture and a decrease in deformity. This improvement in appearance led to an increase in satisfaction with their appearance, as demonstrated by improvements in their body image.

Background: flatfoot is a common deformity characterized by the midfoot arch collapses during walking. As the midfoot is responsible for shock absorption, persons with flatfoot experience increased risk of injuries Aim: to the purpose of this study was to compare some motor-physical factors, lower extremity performance and stability index in male adolescents 10-12 having structural flat foot with and without insole. Materials and Methods: Subjects who utilized medical insoles for four to six months were selected in access from technical orthopedic in Karaj. After parents got aware of the purpose and conditions participating in research, their height and weight were measured. In the first day, they were assessed by motor-physical factors test (agility, speed, endurance), lower extremity performance (one-leg jump, cross jump, maximum distance access, walking six meters) and stability index wearing insole and on the next day without wearing insole. To analyze data, paired t-test was utilized. Wilcoxson was used respectively for parametric and non-parametric data. Results : According to the paired t-test a significant difference was observed in the 6-meter timed test. Mean difference was slower in wearing insole compared to not wearing insole. Moreover, stability index results showed more stability when not wearing insole which eyes were closed to significant. Conclusion: According to the results, wearing insole in individuals with flat foot, could slow down the walking speed. However, wearing insole may improve stability index when visual input is not in access.
