Abstract

Background and Objectives: Mentally retarded children are more sedentary compared to healthy ones because of special mental conditions. This physical inactivity leads to motor and body weaknesses. This study aimed to investigate the effect of 8 weeks of rebound exercises on static and dynamic balance in educable mentally retarded children.
Methods: This semi-experimental study was conducted on 30 male students aging 7-11 years and studying at special schools of Lordegan who were selected through convenience sampling. The children’s mean age was 8.4±1.27 years and their mean IQ was 62.10±5.88. The subjects were randomly assigned to a control (n=15) and an intervention (n=15) group according to their IQ scores. The standardized sport tests for mentally retarded people of American College of Sport Medicine (ACSM) and Brockport Physical Fitness Test (BPFT) were used to assess health-related physical fitness factors. During the 8-week intervention, the intervention group performed rebound exercises in three 45-minute sessions per week. At the end of this period, post-test was performed for both groups. The data were analyzed using repeated measures ANOVA.
Results: The findings showed that rebound therapy exercises had a significant effect on cardio-respiratory endurance (P=0.006), muscular endurance (p>0.0001), and foot explosive strength (p=0.048) in mentally retarded children. However, they had no significant effects on general flexibility (P=0.051) and body composition (p=0.198).
Conclusion: Thefindings indicated that rebound exercise therapy could be used in rehabilitation of mentally retarded children.
