This study examines the effectiveness of two modes of exercise on inhibitory control in adults with Down Syndrome (DS). Thirteen participants attended four sessions: a baseline assessment, an Assisted Cycling Therapy (ACT) session, a Resistance Training (RT) session, and a session of No Training (NT). In the baseline assessment, 1-repetition max (1RM) measurements and voluntary pedal rate measurements were taken. In the resistance training session, the leg press, chest press, seated row, leg curl, shoulder press, and latissimus pulldown were performed. In the cycling intervention, the participant completed 30 minutes of cycling. The Erikson Flanker task was administered prior to each session (i.e., pretest) and after the intervention (i.e., post-test). The results were somewhat consistent with the hypothesis that inhibition time improved more following RT and ACT than NT. there was also a significant difference between ACT and NT. Additionally, it was hypothesized that all measures would improve following each acute exercise intervention, but the most significant improvements were seen following ACT. In conclusion, an acute session of ACT demonstrated a significant trend towards improvements in inhibitory control in adults with DS which we interpreted using a model of neural changes.

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.

Research on the correlation between exercise and mental health outcomes has been a growing field for the past few decades. It is of specific interest to look at how physical activity affects psychological outcomes and it’s efficacy for treating mental health disorders. The current treatment options for depression and anxiety are not suitable for everyone and therefore there is a need for a more accessible and cost-effective form of treatment, like exercise. Furthermore, exercise as a treatment is also linked with many more health benefits. Indeed a wealth of studies have explored the relationships between exercise and depression as well as exercise and anxiety, showing exercise to be a positive predictor of mental health. The following paper will serve to: define depressive and anxiety disorders, explore the research on the effects of physical activity prescriptions on the outcomes of such disorders, create evidence-based applied recommendations for different disorders, and explore the mechanisms by which exercise mitigates symptoms to ultimately accredit the prescription of exercise as a form of treatment for mental health disorders.

The purpose of this thesis project was to examine the trajectories of physical activity among newly-diagnosed Obstructive Sleep Apnea (OSA) patients within the UC+WS group of the SleepWell24 study across the first 60 days of CPAP use, alone and based on Apnea-Hypopnea Index (AHI), Body Mass Index (BMI), sex, and age. The study utilizes objective data from the SleepWell24 randomized controlled trial conducted by a collaborative research team at Arizona State University and Mayo Clinic Arizona and Rochester. Participants use wearable sensors to track activity behaviors, such as sleep, sedentary behavior, light-intensity physical activity (LPA), and moderate-vigorous physical activity (MVPA). The primary aim of the study was to examine the physical activity trajectories among newly-diagnosed OSA patients over the first 8 weeks of CPAP use, utilizing the physical activity data from wearable sensors. The secondary aim was to assess the trajectories of physical activity between categories of AHI, BMI, sex, and age. Multilevel modeling was used to account for clustering within participants considering between and within subject variations, and week was used as a level 1 predictor in the model for LPA, and MVPA, and total activity (sum of LPA and MVPA), while between subject factors of BMI, sex, age, and AHI were also included in the model. It was found that there were no statistically significant trajectories of LPA, MVPA or total activity over the first 8 weeks of CPAP use within the sample of 30 participants. However, a few notable differences in physical activity were seen between categories of age, sex, and BMI. Also, there was a significant interaction found between BMI and each week that influenced the trajectory of physical activity within obese patients, as compared to participants considered overweight or with a lower BMI. Ultimately, this study provides insight into patterns of physical activity seen in a clinical population of OSA patients over the initial period of CPAP use.

Adolescent survivors of sex trafficking are at risk for poor health outcomes and may be less likely to adopt healthy lifestyle behaviors such as physical activity. Survivors of childhood traumas may be less likely to engage in physical activity due to lack of self-efficacy. The present study was a case-series of a pre-post, single-arm physical activity intervention to test whether the program could increase self-efficacy among adolescent survivors of sex trafficking. The intervention was 8-weeks of 60-minute aerobic physical activity classes offered three times per week at a residential center for adolescent girls who are survivors of sex trafficking and sexual abuse. The primary outcome was physical activity-related self-efficacy as measured by the Sport Competence subscale of the Physical Self Perception Profile (PSPP) questionnaire. Secondary outcomes included self-reported physical activity, emotional eating, and sleep habits. All outcomes were measured at baseline, 4 weeks, and 8 weeks. Five participants were enrolled in the study. Two participants experienced an increase in the Sport Competence subscale of the PSPP Questionnaire by Week 4 of the study and then a decrease by Week 8 of the study. Another participant experienced no change in the Sport Competence subscale score. Scores for the last two participants could not be determined due to invalid data. These findings suggest that more research is needed on enhancing healthy behaviors among adolescent sex trafficking survivors.

Background and Purpose— There is limited conclusive data on both pharmacological and holistic treatment options to improve cognition in adults after stroke. In particular, there is lacking evidence for cognitive rehabilitation in the subacute and chronic phases when cognitive impairment may be more perceptible. In this meta-analytic review, our primary objective was to determine the cognitive effects of aerobic exercise on post-stroke adults in the post-acute phases. Secondary objectives were to investigate the differential effects of aerobic exercise on sub-domains of cognitive function.
Methods— Data were extracted and filtered from electronic databases PubMed (MEDLINE), CINAHL, Embase, PsycINFO, and Scopus. Intervention effects were represented by Hedges’ g and combined into pooled effect sizes using random effects models. Heterogeneity was evaluated using the Chi-squared (Q) and I-squared statistics.
Results— Five studies met inclusion criteria, representing data from 182 participants. The primary analysis produced a positive overall effect of aerobic exercise on cognitive performance (Hedges’ g [95% confidence interval]= 0.42 [0.007–0.77]). Effects were significantly different from zero for aerobic interventions combined with other physical activity interventions (Hedges’ g [CI] =0.59 [0.26 to 0.92]), but not for aerobic interventions alone (P= 0.40). In specific subdomains, positive moderate effects were found for global cognitive function (Hedges’ g [CI] =0.79 [0.31 to 1.26]) but not for attention and processing speed (P=0.08), executive function (P= 0.84), and working memory (P=0.92).
Conclusions— We determined that aerobic exercise combined with other modes of training produced a significant positive effect on cognition in adults after stroke in the subacute and chronic phases. Our analysis supports the use of combined training as a treatment option to enhance long-term cognitive function in adults after stroke. Further research is needed to determine the efficacy of aerobic training alone.

The relationship between sleep and physical activity is an area of growing scientific interest, particularly in the context of older adults. The importance of examining long sleep duration and its influence on physical activity in this demographic becomes increasingly relevant given rising healthcare costs. This dissertation aims to investigate this intricate relationship via secondary analysis by examining the effects of moderate time-in-bed (TIB) restriction (60 minutes per night)) on various intensities of physical activity (sedentary, light, moderate, vigorous, moderate-vigorous physical activity) in older adults classified as long sleepers and average duration sleepers. It was hypothesized that moderate TIB restriction would result in differential changes in physical activity levels across various intensities, with long sleepers exhibiting increased physical activity and average sleepers displaying decreased activity, potentially influenced by alterations in TST (total sleep time) and SE (sleep efficiency). Utilizing a randomized controlled trial design, this study examined the effect of treatment changes in objectively measures activity (waist actigraphy) and subjects physical activity levels as measured by the Godin Leisure-Time Exercise Questionnaire . Eligible participants were long sleepers (sleeping > 9 hours per night) and average sleepers (sleeping 7-9 hours per night). Both types of sleepers were either randomized to TIB restriction or asked to maintain their average sleep patterns. Mean TIB restriction compared with baseline was 39.5 minutes in average sleepers and 52.9 minutes in long sleepers randomized to TIB restriction . Contrary to the original hypothesis, no significant effect of TIB restriction was observed across all physical activity levels in either long sleepers or average sleepers. However, a notable association was found between increased sleep efficiency (+0.09% [SD = ± 4.64%]) and light physical activity (±31 minutes [SD = ± 104.81, R=0.445, P < 0.007]) in long sleepers undergoing TIB restriction. While this study presents several methodological limitations, including its nature as a secondary analysis and the less-than-intended achievement of TIB restriction, it adds a valuable layer to the existing body of research on sleep and physical activity in older adults. The findings suggest that moderate TIB restriction may not be sufficiently impactful to change behavior in physical activity levels, thus highlighting the need for more nuanced, targeted research in this domain.

Background: Creation and reuse of reliable clinical code sets could accelerate the use of EHR data for research. To support that vision, there is an imperative need for methodologically. driven, transparent and automatic approaches to create error-free clinical code sets. Objectives: Propose and evaluate an automatic, generalizable, and knowledge-based approach that uses as starting point a correct and complete knowledge base of ingredients (e.g., the US Drug Enforcement Administration Controlled Substance repository list includes fentanyl as an opioid) to create medication code sets (e.g., Abstral is an opioid medication with fentanyl as ingredient). Methods: Algorithms were written to convert lists of ingredients into medication code sets, where all the medications are codified in the RxNorm terminology, are active medications and have at least one ingredient from the ingredient list. Generalizability and accuracy of the methods was demonstrated by applying them to the discovery of opioid and anti-depressant medications. Results: Errors (39 (1.73%) and 13 (6.28%)), obsolete drugs (172 (7.61%) and 0 (0%)) and missing medications (1,587 (41.26%) and 1,456 (87.55%)) were found in publicly available opioid and antidepressant medication code sets, respectively. Conclusion: The proposed knowledge-based algorithms to discover correct, complete, and up to date ingredient-based medication code sets proved to be accurate and reusable. The resulting algorithms and code sets have been made publicly available for others to use.

Exercise is widely recognized for its myriad of health benefits, particularly in the realm of chronic disease prevention and treatment. Despite this knowledge, exercise remains significantly underutilized in the United States, with only a quarter of the population meeting the recommended physical activity guidelines set by the Department of Health and Human Services (Piercy et al., 2018). Recent research has spotlighted specific regions known as Blue Zones, where natural movement is incorporated into daily lives and populations are characterized by increased longevity and improved health outcomes, including lower rates of chronic diseases. This study aimed to explore and compare exercise behaviors between the United States and the Ikaria Blue Zone in Greece, investigating their potential implications for a longer lifespan and enhanced health. Employing ethnographic methods, including immersive observation, semi-structured, qualitative interviews with locals, and the distribution of validated International Physical Activity Questionnaire (IPAQ) surveys, comprehensive data on exercise habits within the Ikarian population was collected in November 2023. The findings from this study shed light on alternative forms of physical activity that have proven successful in populations with increased longevity. By identifying and understanding these practices, there is an opportunity to implement them in the United States, potentially contributing to improved exercise adherence and the prevention and treatment of chronic diseases. This research underscores the significance of cross-cultural insights in developing effective strategies to promote healthier lifestyles and enhance overall well-being.

The purpose of this study was to use the tenets discussed in the Self-Determination Theory to explore how adolescents are motivated to engage in physical activity and examine the reasons for their participation - or lack thereof - in order to determine the influence of motives on physical activity behaviors in an adolescent population. The relative autonomy continuum of the Self-Determination Theory includes amotivation, external regulation, introjected regulation, identified regulation, integrated regulation, and intrinsic motivation. These different levels will be assessed. Participants were seventh grade students at a middle school in the Phoenix metropolitan area (n=70). The adolescents’ relative autonomy levels were assessed with a modified version of the Behavioral Regulation in Exercise Questionnaire. Individual motivational factors were measured from a modified version of the Exercise Motivations Inventory. The adolescents’ locus of causality was then measured using the Locus of Causality for Exercise Scale. Participants were asked to answer two additional questions assessing their perceived time barrier and frequency of physical activity participation. The data were scored using the scoring guidelines provided by each questionnaire after collection through a Google Form and analysis on Google Sheets. Results showed that adolescents with higher levels of identified regulation (3.88), intrinsic motivation (4.22), and locus of causality (4.67) were more likely to also engage in higher levels of physical activity. These findings could be used for future research that focuses on school-based interventions for physical activity through enjoyment so as to increase identified regulation and intrinsic motivation while shifting to a more internal locus of causality in order to increase their overall leisure-time physical activity as a way to combat the increasing rates of childhood overweight and obesity in the United States.
