Abstract
Background and Aim: Exercise training is important to reduce the physical performance disorders among mentally retarted children. The aim of the present study was to analyze the effect of two combined exercise trainings (trampoline-racquet and rope skipping-racquet) on physical fitness indicators and movement ability among mentally retarded children. Materials and Methods: Twenty-four mentally retarded male students, aged 8-15 y., with an IQ of 50 to 70 were purposefully selected and randomly divided into two experimental groups and one control (each eight persons). One of the experimental groups performed trampoline-racquet training, and the second group performed rope-racquet training (eight-week, three sessions per week, 60 min in each session). The control group did not participate in the intervention exercise and followed the school’s regular training programs. Before and after the exercise trainings, physical fitness and mobility tests were taken from all subjects. Analysis of variance with repeated measures and Bonferroni’s tests were used for data analysis at a significance level of p≤0.05. Results: Both exercise trainings improved static balance with eyes closed, dynamic balance, abdominal muscle endurance, lower limb muscle power, and motor ability compared to the control group, but there was no significant difference between the two training programs. Moreover, the static balance index of the left leg with eyes open and explosive power was significantly improved only in the rope skipping-rocket group compared to the trampoline-rocket and also the control group; while there was no significant differences between the indicators of cardiorespiratory fitness and hand muscle power between the three groups. Conclusion: Studies suggest that exercise training programs can improve physical fitness and mobility in mentally retarded children.
