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 United States healthcare system does not perform as well as other countries including Germany and England, despite spending the most money on healthcare. It is well-established that there have been attempts at reform in the U.S. healthcare system multiple times in the past. This research paper describes the health care systems in the U.S., Germany, and England to analyze the strengths to create practical healthcare reform ideas for the U.S. This was done by describing each of the country's health care systems in detail, including the history of each country's health care system, the quality of care, the access to care, and the funding of the health care system. Based on this analysis of these health care systems, recommendations for health care reform are provided for the U.S. with revisions to the Affordable Care Act.

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).

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.

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.

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.

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.
