The effect of linear and non-linear training on learning badminton long serve skills in children with Down syndrome

The aim of the present study was to investigate the effect of linear and non-linear training on learning badminton long serve skills in 9-12-year-old boys with Down Syndrome. The present study was applied, semi-experimental and pre-test, post-test with control group. 45 boys from 9 to 12 years old with Down Syndrome in Tabriz Welfare Center were selected and after homogenization based on the pre-test scores randomly in three groups of linear training (15 people), non-linear training (15 people) and control group ( 15 people) were placed. The acquisition phase consisted of 12 weeks and 2 sessions per week and each session lasted for 60 minutes. The task of the test was badminton long serve. After the end of the acquisition phase, the post-test and 48 hours later the memory test was performed. So that there is a significant difference between the measured steps in linear and non-linear training methods. It was also found that there is a significant difference between the different experimental groups in the post-test and memorization stages, so that the subjects of the linear and non-linear training groups performed better than the control group. In the explanation of the current research, it can be stated that in most motor learning studies, especially those conducted in young people, researchers believe that interventions and training have a significant effect on growth, learning and motor performance, and therefore the type of intervention is necessary.
