Introduction: Weakness in muscle function is one of the most common complications of Down syndrome and is associated with delayed motor growth and decreased muscle function. On the other hand, the role of exercise in improving strength is well known. Therefore, the present study aimed to investigate the effect of eight weeks of trampoline training on balance and muscle strength of men with Down syndrome.
Methods: In this quasi-experimental study, 24 people with Down syndrome (age: 26.8±45.26) were randomly divided into two groups: training and control. The study variables of static and dynamic balance and explosive strength of the subjects were measured before and after the training period respectively, by the stork balance stand test, dynamic Y balance, and Sargent vertical jump. For eight weeks, the subjects performed three 30-minute trampoline sessions each week. Dependent sample t-test statistical method was used for inferential data analysis (p ≥ 0.05).
Results: Eight weeks of trampoline training had a significant effect on increasing peak strength (p = 0.01), mean strength (p = 3.12), and dynamic Y balance in the anterior (p = 0.001) and external posterior (p = 001) direction in individuals with Down syndrome, but has no significant effect on increasing static balace (p = 0.26) and dynamic Y balance in the internal posterior direction (P = 0.28).
Conclusion: Based on the findings of the study, the use of trampoline training in the process of physical rehabilitation of patients with Down syndrome is recommended.
