Description
Adaptive behavior consists of the social, conceptual and practical skills an individual must execute to function independently in their everyday life. Individuals with Down syndrome have limitations in their adaptive behavior due to cognitive and physical deficits. The aim of this study was to examine if an exercise program would improve the adaptive behavior skills in persons with Down syndrome. The exercise intervention, Exercise for Adults with Down Syndrome (ExDS), was a semester long program where adults with Down syndrome participate in twice weekly workouts planned and executed by Arizona State University students. The workouts consisted of an aerobic warm up, aerobic exercises, resistance exercises, balance exercises and stretches. The participants' adaptive behavior and cognitive planning ability were assessed before ExDS and after ExDS. The Adaptive Behavior Assessment System Second Edition (ABAS-II) was used to measure adaptive behavior. The ABAS-II consisted of a forum that addressed the Social, Conceptual and Practical domains of adaptive behavior and was filled out by the participants' caregiver. The Tower of London (ToL) was used to measure cognitive planning ability. The change in the ABAS-II scores from pre- to post-testing were statistically insignificant. The change from pre- to post-testing in the ToL scores approached statistical significance. Limitations included bias caregiver perception and respondent inconsistency. There is a need for further research on the effect of exercise on the adaptive behavior in adults with Down syndrome.

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
The purpose of the present study is to explore a potential rehabilitation alternative/additive, when time, insurance, finances, or lack of knowledge are limitations for mild traumatic brain injury (mTBI) executive function (EF) rehabilitation. The experimental intervention involved two sets of participants an experimental group and a control group. Participants within the experimental and control groups partook in initial (week 1) and final (week 6) EF and TBI assessments. The experimental group additionally participated in four weeks (weeks 2 - 5) of an experimental intervention in beta stage of a web-based application. The aim of the intervention was to train EF skills planning, organization, and cognitive flexibility through serious gamification. At the conclusion of the study, it was observed that participants within the experimental group achieved higher scores on the experimental executive function assessment when compared to the control group. The difference in scores can be attributed to the weekly participation in executive function training.

Description
The present study sought to understand traumatic brain injuries (TBI) impact on executive function (EF) in terms of anticipation amongst individuals with a background in soccer; along with other contributing factors of EF curtailments that inhibit athletes. Within this study 57 participants, with a background in soccer (high school, collegiate, and semi-professional), completed five EF tasks: working memory, cognitive flexibility, attentional control, and anticipation; pattern detection and athletic cues (temporal occlusion). The results of this study concluded that when TBI history, gender, and soccer athletic level are factors, athletes with a soccer level of collegiate and semi-professional had decrements related to pattern detection anticipation; meaning athletes at higher levels had lower average scores on the Brixton Spatial Anticipation Test (BSAT). Additionally, female athletes showed more anticipation decrements related to athletic cues, especially those that are reliant on the initiation of judgment. Overall undiagnosed TBIs and limited understanding on how to approach rehabilitation to mitigate EF decrements, continue to impede individual autonomy amongst athletes. Keywords: Traumatic brain injury, executive function, anticipation, soccer, temporal occlusion, Brixton Spatial Anticipation Test (BSAT), collegiate, semi-professional, pattern detection, rehabilitation

Description
Background: Down syndrome is the leading genetic cause of intellectual disabilities. Executive function is an area that people with Down syndrome have a diminished capacity compared to those in the general population. In recent years it has been determined that acute and chronic exercise has a small but positive effect on measures of executive function in typically developed individuals. The effect has been recorded separately in both aerobic, high-rate passive and resistance exercises in adolescents with DS but has not been compared between exercise types in adults with DS. Methods: A randomized crossover study was utilized to determine the effect of resistance exercise, assisted cycling therapy, and no exercise on executive function and enjoyment in adults with Down syndrome. Resistance Training (RT)- participants completed a total of 16- repetitions of approximately 75% of a 1-RM in the leg press, chest press, seated row, and latissimus pulldown. ACT- participants completed 30-minutes of cycling at 35% above voluntary (e.g., self-selected pace) rate. No-Training (NT)- participants spent 35-minutes playing board games. Cognitive assessments were recorded pre- and post- intervention. The Physical Activity Enjoyment Survey was collected post-intervention. Statistics: The cognitive measures and Physical Activity Self-efficacy scale were analyzed using the delta scores (pre-post) in a Linear mixed models analyais. The main effect of sequence (A, B, C) and intervention (RT, ACT, NT), and visit were assessed. Significance level was set with α=0.05. If any differences were detected, the Bonferroni post-hoc test was used to determine differences. Physical Activity Enjoyment Scale post scores were compared using a General Linear Model. Alpha was set at 0.05 with a Bonferroni post-hoc test to determine differences. A secondary analysis was conducted investigating the effect of participants that completed testing individually compared to those that completed the testing in a group setting. Results: There were no significant difference in the delta score of any of the measures. The secondary analysis also found no significant difference but showed a trend that those tested individually had opposite results than those tested in a group.
