Effects of the special olympics unified sports soccer training program on executive function in adolescents with intellectual disabilities

Abstract

Objective: Executive dysfunction is common in in individuals with intellectual disability (ID). This study examined the effects of the Special Olympics Unified Sports (UNS) soccer program on executive function (EF) and prefrontal cortex activation in ID adolescents. Methods: Functional near-infrared spectroscopy (fNIRS) was utilized to compare EF between a group participating in UNS soccer training (n = 18) and a control group (n = 26) in the flanker task, 2-back task, and dots–triangles task. Results: The results revealed that the soccer group performed significantly better in the dots-triangles and 2-back tasks than the control group. However, it is unclear whethersoccer training may improve activation of R-DLPFC during performance of the dotstriangles task. In the 2-back task, activation in the right frontopolar area (R-FPA) was lower in the soccer group when compared to the control group. Notably, no significant differences were observed in the flanker task Conclusion: In conclusion, UNS soccer training may positively affect working memory in adolescents with intellectual disabilities by improving activation of RFA, but whether it activates R-VLPFC is uncertain. These results indicate that the UNS soccer trainingprogram holds promise for enhancing executive function in adolescents with ID, and improving the quality of life in this population.
