The influence of exercise on cognitive function is an important topic. This study examines the effects of different interventions on executive functioning, specifically on cognitive planning, which is a sub-category of executive function, in adults with Down syndrome. Research has shown that an acute bout of Assisted Cycle Therapy improved manual motor functioning, cognitive planning, and information processing in adolescents with Down syndrome but there is a lack of research when it comes to resistance training. Fourteen adults with Down syndrome completed acute sessions of Assisted Cycle Therapy, Resistance Training, and No Training. Cognitive planning was measured by the Tower of London test. The results show that cognitive planning can be improved following Assisted Cycle Therapy. An increase in cognitive planning was also present in the No Training group which may be a result of cognitive stimulating games that were played. In conclusion, this study suggests that teachers, therapists, etc. that work with adults with DS, should be sure to include a cognitive component in all activities.

Cognitive functioning is an extremely crucial part of daily living. In individuals with Down Syndrome (DS) these tasks get even more challenging. The aim of this study is to determine the effects of Assisted Cycling Therapy (ACT) on cognitive functions in children with Down Syndrome (DS). This study examines the change in cognitive functioning using tests like Reaction time, Tower of London, and Card Sorting over an eight week intervention. All seven participants in the study were assigned to complete the ACT intervention, in which they rode a stationary bike with the assistance of a motor to maintain a cadence of at least 35% greater than their voluntary cycling speed. All participants completed the ACT intervention but a few were unable to complete some cognitive functioning tests due to their intellectual abilities. Overall, the results of this study showed that information processing, task-switching and problem solving improved following the eight week ACT intervention. These results provided more scope for future research in this field which can be done by modifying the time period of the intervention, increasing sample size of the study as well as conducting additional cognitive function tests. The results of our study are discussed with respect to the upward regulation of neurotrophic factors which are involved in increasing the functioning within the prefrontal cortex following exercise intervention.

The purpose of this study was to examine the validity of a modified Assisted Cycling Therapy bicycle for improving depression in children with Down Syndrome (DS). Seven participants completed 2x/week for 8 weeks, 30 minutes at a time of ACT, in which participants’ voluntary pedaling rates were augmented via the bicycle motor, ensuring that they were pedaling at a rate greater than their self-paced rate. Depression was measured using a modified version of the Children’s Depressive Inventory, called the CDI-2. Our study demonstrated that the scores from the CDI-2 decreased, demonstrating less depressive symptomatology after the conclusion of the 8 week intervention. Our results were interpreted via our model of the mechanisms involved in influencing the success of ACT. Future research would include a greater sample size, a more relevant measure of depressive scores, and a consistent data collection environment. However our initial pilot study showed promising results for improving mental health in children with DS.

Down syndrome (DS) is caused by either an extra copy of chromosome 21 or by extra material on chromosome 21. This causes various levels of intellectual disability and issues with gross motor skill development which can prevent these individuals from participating in activities of daily living (ADL) such as getting dressed, self-care, or grocery shopping. People with DS have a decreased ability to balance, an abnormal and slower gait pattern, difficulty adapting to new environments, and a lack of improvement in these areas with growth and development when compared to their neurotypical peers. The objective of this study was to determine the immediate effects of resistance training (RT) and assisted cycle therapy (ACT) on adults with DS’s balance ability and gait speed. Each participant completed one session of RT, ACT (stationary cycling with the assistance of a motor to maintain a cadence of at least 35% greater than their voluntary cycling speed), and no training in a randomly selected order. Balance and gait speed were measured by a Clinical Test of Sensory Interaction on Balance (CTSIB) (i.e., eyes open firm surface, eyes closed firm surface, eyes open foam surface, eyes closed foam surface) on a Balance Tracking System Board (Btracks board) and by a Timed Up and Go (TUG) test. A total of ten participants’ data was used for analysis. The measures of total path length (cm), anterior-posterior (AP) excursion, and medial-lateral (ML) excursion were used to analyze the CTSIB. The average time was used to analyze the TUG test. The results showed that the eyes closed foam surface balance task was the most challenging balance task for every participant in every intervention. Furthermore, the most improvement was evident in the eyes closed foam surface balance task from pre to post intervention in all of the interventions. Post hoc tests also indicated statistically significant improvements of path length from pre to post in the RT intervention with the eyes closed foam surface balance task as well as with AP excursion in the ACT intervention with the eyes closed foam surface balance task. Possible explanations for improvements from pre to post in the eyes closed foam balance task across all interventions will be discussed with respect to the length of the intervention, and the effect of strength, social and learned factors on balance in adults with DS.

The primary goal for this study is to assess and develop an understanding of the effects of Assisted Cycling Therapy (ACT) on self-efficacy and exercise perception of children with Down syndrome (DS). ACT is a stationary bicycle that has a mechanical motor that moves the pedals 35% faster than their self-selected rate. This intervention continued for 30 minutes 2x/week for 8 weeks. A total of seven participants were assessed through the study, however, due to a variety of limitations only two participants completed pre and post testing questionnaires. Our results showed that self-efficacy improved following ACT. Both participants experiences improvement in their total self-efficacy score. However, only one participant showed improvement in exercise perception following the intervention. Interpretations of our results are analyzed in consideration with behavioral limitations that may be present within children with DS. Additionally, these results provided guidance for future research. These include alterations to the intervention time period, as well as the sample size of the study.
