The purpose of this preliminary study was to examine the difference in cognitive performance between college students with and without ADHD and to explore the effects of acute exercise on multiple aspects of executive functions and on serum brain derived neurotrophic factor （BDNF）. Methods： College students （normal： n = 10; ADHD： n = 10） performed the Stroop Test, Trail Making Test, and Digit Span Test prior to and after an acute exercise intervention. Blood samples were obtained prior to the pre-test cognitive test performance and then again after exercise and prior to the post-test cognitive test performance. Results： Students with ADHD exhibited impaired executive functions, particularly on inhibition. Additionally, while acute exercise improved all aspects of executive functions in those without ADHD, acute exercise only improved inhibitory performance for those with ADHD. Further, BDNF was not influenced by acute exercise regardless of the subjects＇ ADHD status. Conclusion： These results provide preliminary evidence for exercise as a potential adjunct treatment for benefitting inhibition in college students with ADHD.展开更多

We summarized the main trend and performance of community autonomy administration, in terms of government functions, cadre staff work mode and operation mechanism. Then based on the analysis of its root cause, we proposed some strategies to solve the issues of community autonomy administration.展开更多
