Abstract
Introduction: Jumping rope is a complete physical activity in which the muscles of the upper and lower limbs work. In addition, it contributes to the development of coordination, balance, agility, rhythm and velocity in lower limbs (Chenchao, 2012). Despite the research, it seems that due to the lack of space and facilities available at the special centers for mentally retarded children, the program is codified using simple, inexpensive and safe games and tools to create an appropriate and vibrant environment for this activity. Children are not provided with the help of the development of locomotor skills. Jumping rope is a simple activity that requires only a rope and can be done anytime and anywhere (Chengdu, 2012). The purpose of this study was to investigate the effect of determined jumping rope exercises on locomotors skills in educable mentally retarded children.
Methodology: In the quasi-experimental study, 30 children with educable mental retardation (age 8 to 11 years) were selected with purposive sampling method. All subjects were tested using locomotors subscale in Test of Gross Motor Development and based on different scores of this test, were randomly divided into two experimental (n=15) and control (n=15) groups. Experimental group executed jumping rope exercises for 8 weeks, 3 sessions per week and each session lasting 45 to 50 minutes. In this period, control group executed current school activities and had no other sports regularly activity to be effective. Finally, both groups were tested again and afterwards, required data was collected. To examine, whether the assumptions are significant the analysis of covariance was used.
Results: Data analysis revealed that after performing determined jumping rope exercises, locomotor skills, were significantly increased F(1 27) = 76.95 ,p=0.001.
Discussion: Better performance in Jumping Rope can enhance coordination (Echin, 2012). As noted above, it seems that another possible reason for progress in locomotor skills is to increase motor coordination and improve timing and coordination in different parts of the body after the training program. Another possible reason for the significant effect of determined jumping rope exercises on locomotor skills could be to increase the static and dynamic balance. Because, as we know, balance plays a role in the implementation of locomotors skills. According to these findings, it is suggested that jumping rope exercises would be implemented for improving locomotors skills of educable mentally retarded children in special schools.
