Description
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.

Description
Physical activity as a health or nutrition related intervention might stimulate appetite and increase hunger due to increased energy expenditure. This study analyzed the effect of a postprandial 15-minute walk on the hunger and energy intake of 10 obese, pre-diabetic adults. Subjects participated in three 4-hour trials: a walk treatment (consume highly glycemic meal, walk for 15 minutes at a moderate pace, and rest for 4 hours), a fiber treatment (consume highly glycemic meal enriched with soluble fiber and rest for 4 hours), and a control treatment (consume highly glycemic meal without fiber and rest for 4 hours). The effects of each treatment on hunger and energy intake were measured using a Likert scale analysis (ranging from "completely satisfied" to "extremely hungry") at 4 hours post-treatment and pre/ post 24-hour dietary logs. The results showed no significant increase or decrease on hunger or energy intake for both the walk and the fiber treatment compared to the control treatment. This denies the idea that physical activity might increase short-term hunger, and supports the use of physical activity as a viable nutrition related intervention tool.

Description
With obesity and metabolic diseases reaching epidemic levels, it is important to find ways to increase physical activity and improve diet. Previous studies have shown that improvements in mood can increase desire to perform physical activity, and that vitamin C intake is linked to improvements in mood. Based on this, two hypotheses were formed and tested to investigate the effect on physical activity levels and mood states from vitamin C supplementation at a dose of one gram per day in the form of a novel functional food. Thirty-one college students or faculty at Arizona State University were screened from a pool of applicants and placed into either a vitamin C or placebo group; all participants received the novel functional food to eat daily for four weeks. Serum levels of vitamin C, weight, height, BMI, body fat percentage, mood, and physical activity were measured before and after the functional food intervention. Vitamin C changed significantly through the course of the study in the experimental group. Baseline data for participants showed a positive correlation between vitamin C status and vigor, and a negative correlation between vitamin C status and weight and BMI. Physical activity was not related to vitamin C status, according to baseline data, and it did not significantly change over the course of the study. The results indicate that variance in BMI can be attributed to vitamin C status, but the study should be refined and tested again.

Description
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.

Description
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.

Description
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.

Description
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.

Description
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.

Description
The various muscle fiber types as they are determined by their composition of the myosin heavy chain (MHC) isoform, whether it is pure type I (slow twitch) or pure type II (fast twitch), or a hybrid fiber type, are known to impact the overall metabolic function in humans (Serrano et al., 2019). While it is recognized that active high performing individuals (such as strength athletes) have a larger distribution of type IIa muscle fibers, the distribution of hybrid fibers in muscle of lean and physically inactive human fibers remains unknown (Serrano el. Al., 2019). Hybrid fibers are thought to be fibers in the transitional phase of muscle adaptation (Williamson et al. 2001). Previous studies have shown that resistance exercise training increases specialized fiber composition as compared to hybrid variants. Given the relationship between reduced metabolic activity and quantity of transitional fibers, it is possible that sedentary individuals may have a less effective metabolic profile. This study examines the composition of MHC content in muscle fibers, with a special emphasis on describing hybrid fibers in lean, physically-inactive individuals, to improve our understanding of muscle adaptation and metabolic health. The study provides a directed analysis of hybrid fibers into I/IIa and IIa/IIx groups in physically inactive humans, which adds to our knowledge of muscle fiber specialization in response to physical activity. This research proposes to test the hypothesis that an individual's distribution of muscle fiber types is influenced by the prevalence of hybrid fiber types, when categorized using single fiber SDS-PAGE, with a specific focus on lean individuals. Through single muscle fiber SDS PAGE analysis of 1821 fibers from 11 participants, 293 were identified as hybrid fibers, with a greater prevalence of IIa/IIx hybrids compared to lean-active healthy adults. Through this investigation, we aim to contribute valuable insights into the complex interplay between muscle fiber types, potentially informing future therapeutic strategies targeting muscle function and metabolic health.
