Description
Previous research has found improvements in motor and cognitive measures following Assisted Cycle Therapy (AC) in adolescence with Down syndrome (DS). Our study investigated whether we would find improvements in mental health in older adults with DS as measured from the Adapted Behavior Dementia Questionnaire (ABDQ), Physical Activity Self Efficacy Scales (PACES), Children's Depressive inventory, which are early indicators of Alzheimer's disease (AD) in persons with Down syndrome. This study consisted of seven participants with Down syndrome between the ages of 31 and 54, inclusive, that cycled for 30 minutes 3 x/week for eight weeks either at their voluntary cycling rate (VC) or approximately 35% faster with the help of a mechanical motor (ACT). Our results were consistent with our prediction that self efficacy improved following ACT, but not VC. However, our results were not consistent with our prediction that dementia and depression were improved following ACT more than VC. These results were interpreted with respect to the effects of exercise in older adults with DS. Future research should focus on recruiting more participants, especially those with deficits in mental health.

Does assisted cycle therapy influence activities of daily living in older adults with Down syndrome?
Description
The aim of this study is to examine the relationship between Assisted Cycle Therapy, leisure time activity levels, fine motor control, and grip force in older adults with Down syndrome (DS), all of which affect activities of daily living (ADL) and therefore quality of life. This is relevant because this particular group is at risk for developing early onset Alzheimer's disease (AD), which presents itself uniquely in this population. The parent or guardian of six participants with DS completed Godin's Leisure Time Exercise Questionnaire and the participants themselves completed Purdue Pegboard and grip force assessments before and after an 8-week exercise intervention. The results were inconsistent with past research, with no change being seen in fine motor control or grip force and a decrease being seen in leisure activity. These findings are indicative of the importance of the effect of fatigue on leisure activity as well as maintaining elevated heart rate throughout exercise interventions.

Description
This study examines the one month retention of executive function benefits gained by adolescents with Down syndrome after an 8-week aerobic exercise intervention. Sixteen participants were randomly divided between voluntary (VC) (i.e., self-selected cadence) and assisted (AC) (i.e., 30% faster than self-selected cadence accomplished by a motor) cycling groups, with one participant used as a control (NC). Both cycling groups rode a stationary bicycle, for 30 minutes, three times a week, for eight weeks. At the beginning (i.e., pretest) and end (posttest) of the 8-week session, three executive functions including: set-switching, inhibition, and cognitive planning, were tested. Approximately one month after the posttest, all participants underwent the cognitive testing again. The results showed that for the AC group cognitive planning improved after eight weeks of assisted cycling and these improvements were maintained after one month of no cycling. However, no significant differences were found between the cycling groups for our measure of inhibition. Set-switching appeared to be improved by both types of exercise, rather than only assisted, but the improvements were not maintained during the one month retention period for either group. Thus, our results suggest that Assisted Cycling causes potentially permanent changes in the brain in regards to cognitive planning.

Description
The aim of this study was to examine the effects of Assisted Cycle Therapy (ACT) on self-efficacy and exercise perception in older adults with Down syndrome (DS) after a three times a week for 8 weeks intervention. Thirteen participants were in the ACT group in which a motor assisted their cycling to be performed at least 30% faster than voluntary cycling (VC), 11 participants were in the voluntary cycling group and two participants were in the no cycling (NC) group. The results showed that both exercise groups (i.e., ACT and VC) improved in their self-efficacy after the 8 week intervention. In addition, exercise perception improved following ACT and not VC or NC. Our results are discussed with respect to their future implications for exercise in the DS population. It might be that the yielded results were due to differences in effort required by each intervention group as well as the neurotrophic factors that occur when muscle contractions create synaptic connections resulting in improvement in cognition and feelings of satisfaction. In the future, research should focus on the psychological factors such as social accountability and peer interaction as they relate to ACT and physical activity in person's with DS.

Description
Lower extremity function is vital for activities of daily living especially in stroke survivors. An innovative way to improve lower extremity function may be Assisted Cycle Therapy. This is among the first studies to examine ACT in stroke survivors. Twenty-three participants post-stroke performed ACT, VC and NC and pre and post measures of lower extremity function were conducted with the Lower Extremity Motor Coordination Test (LEMOCOT). The results showed that the non-paretic lower extremity improved its function after ACT, but not after VC or NC. Lower extremity function in the paretic leg improved after ACT and VC, but not after NC. These results suggest that ACT resulted in increased production of BDNF in the motor cortex which resulted in improvements in global motor function.

Description
Upper extremity function is vital for activities of daily living especially in stroke survivors. An innovative way to improve upper extremity function has been shown with Assisted Cycle Therapy (ACT). This is among the first study to examine ACT in stroke survivors. 13 stroke survivors performed ACT, VC, and NC and pre and post measures of upper extremity function were conducted with the box and blocks test (BBT). The results showed that non-paretic upper extremity improved its function after ACT and VC, but not after NC. For the paretic arm, while the results did not reach conventional levels of significance, improvements in upper extremity function following ACT more so than VC or NC. These results were interpreted to suggest that ACT resulted in increased production of BDNF in the motor cortex, which resulted in improvements in global motor function.

Description
Executive function is vital for activities of daily living especially in stroke survivors because it is critical to everyday tasks (e.g., driving, cooking, etc.). An innovative way to improve executive function may be Assisted Cycling Therapy (ACT). This is among the first studies to use a Stroop task to measure inhibition, selective attention, and information processing speed following ACT in stroke survivors. Twenty-three participants post-stroke performed ACT, voluntary cycling (VC) and no cycling (NC). The results showed that there were improvements in the Stroop task following an acute session of ACT but not following VC or NC. These results suggest that ACT resulted in increased afferent information which may have resulted in increased arousal and excitability in regions of the prefrontal cortex. These factors have been shown to improve executive function.

Description
Previous research has found improvements in motor and cognitive measures following Assisted Cycle Therapy (AC) in adolescence with Down syndrome (DS). Our study investigated whether we would find improvements in older adults with DS on measures of leisure physical activity (GLTEQ) and sleep, which are early indicators of Alzheimer's disease (AD) in persons with Down syndrome. This study consisted of eight participants with Down syndrome between 31 and 51 years old that cycled for 30 minutes 3 x/week for eight weeks either at their voluntary cycling rate (VC) or approximately 35% faster with the help of a mechanical motor (AC). We predicted that, based on pilot data (Gomez, 2015), GLTEQ would either maintain or improve after AC, but would decrease after VC and would stay the same after NC. We predicted that the sleep score may improve after both VC or AC or it may improve more after VC than AC based on pilot data related to leisure activity. Our results were consistent with our prediction that GLTEQ will either maintain or improve after AC but will decrease after VC. Our results were not consistent with our prediction that sleep may improve after both VC or AC or it may improve more after VC than AC, possibly because we did not pre-screen for sleep disorders. Future research should focus on recruiting more participants and using both objective and subjective measures of sleep and physical activity to improve the efficacy of the study.

Description
This study examines the effectiveness of two modes of exercise on self-efficacy (SE) in adolescents with Down syndrome (DS). Thirty-nine participants were randomly divided into a voluntary cycling group (VC) (i.e., self-selected cadence), an assisted cycling group (ACT) (i.e., at least 30% faster than self-selected cadence accomplished by a motor), or a no exercise group (NC). In each cycling intervention the participant completed 30 minute cycling sessions, three times per week for a total of eight weeks. Two subsets of the Physical Activity and Self Efficacy Survey were administered prior to cycling (i.e., pretest) and after the eight week intervention (i.e., post-test). The results were consistent with the hypothesis that self-efficacy would improve after ACT, however there was not improvement after the VC condition as hypothesized. It was also hypothesized that exercise perception would improve following the ACT intervention; execise perception showed a trend of improvement after ACT, but the data did not reach significance. Limitations include the wide variability of the DS population. This limitation is responsible for the variation in mental age seen in the intervention groups and could be responsible for the non-significance of the exercise perception data. To generalize our results for parents, therapists, teachers, etc., our recommendation is for persons with DS to participate in physical activity that is easy for them at first \u2014 a simplified sport or active game, assisted cycling, brisk walking \u2014 so that they have a positive experience with exercise. Showing individuals with DS that they can be proficient exercisers will likely improve their self-efficacy and motivate them to engage in more PA over time. In conclusion, eight weeks of moderate ACT exercise demonstrated a significant trend for improved self-efficacy in adolescents with DS.

Description
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.
