Description
This study examines the effect of exercise therapy on a stationary bike on cognitive function, specifically inhibition and set-switching, in adolescents with Down syndrome. 44 participants were randomly divided between the voluntary cycling therapy group (VCT) (i.e., self-selected cadence), assisted cycling therapy group (ACT) (i.e., 30% faster than self-selected cadence accomplished by a motor), and a control group (NC) in which the participants did not undergo any exercise therapy. 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 (i.e., posttest) of the eight-week session the participants completed tasks to evaluate their cognitive function. They completed three trials of the card sort test (i.e., set-switching) and three trials of the knock-tap test (i.e, inhibition) before and after eight-weeks of cycling therapy. The scores of these tests were analyzed using one-way ANOVA between groups and paired samples t-tests. The results showed that after eight-weeks of cycling therapy the participants in the VCT group performed worse in the knock-tap test, but improved in two trials of the card sort test. The results also showed that the participants in the ACT group performed worse after eight-weeks of exercise therapy in one trial of the card sort test. No significant changes were seen for the control group. Due to the fact that on average the participants in the VCT group cycled with a higher heart rate, our results suggest exercise that significantly elevates heart rate can improve cognitive function, specifically set-switching, in adolescents with Down syndrome.

Description
The anthracycline drug Doxorubicin (DOX) is a highly effective treatment for breast cancer, but its clinical utility is limited by dose-dependent cardiovascular toxicity. The toxic effects are partly attributed to DOX-induced generation of reactive oxygen species, which may impair nitric oxide-mediated vasodilation. Exercise training activates antioxidant defense mechanisms and is thus hypothesized to counteract oxidative stress when initiated prior to DOX administration. Adult 8-week old, ovariectomized female Sprague-Dawley rats were divided into 4 groups: sedentary + vehicle (Sed+Veh); Sed+DOX; exercise + veh (Ex+Veh); and Ex+DOX. Rats in the exercise groups were preconditioned with high intensity interval training consisting of 4x4 minute bouts of exercise at 85-95% of VO2peak separated by 2 minutes of active recovery performed 5 days per week. Exercise was implemented one week prior to the first injection and continued throughout the study. Animals received either DOX (4mg/kg) or veh (saline) intraperitoneal injections bi-weekly for a cumulative dose of 12 mg/kg per animal. Five days following the final injection, animals were anesthetized with isoflurane, decapitated and aortas and perivascular adipose tissue (PVAT) were removed for western blot analyses. No significant differences in aortic protein expression were detected for inducible nitric oxide synthase (iNOS) or the upstream activator of endothelial nitric oxide synthase (eNOS), Akt, across groups (p>0.05), whereas eNOS protein expression was significantly downregulated in Sed+DOX (p=0.003). In contrast, eNOS expression was not altered in Ex+DOX treated animals. Protein expression of iNOS in PVAT was upregulated with exercise in the DOX-treated groups (p=0.039). These findings suggest that exercise preconditioning may help mitigate vascular effects of DOX by preventing downregulation of eNOS in the aorta.

Description
Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder. It is primarily misdiagnosed or undiagnosed in women until adulthood is reached. There are multiple effective therapies available once a diagnosis of ADHD is made. These include, but are not limited to, stimulant prescription medications, complementary and alternative medicine therapies (CAM) and gut health. Complementary and alternative medicine therapies can include meditation/spiritual health, Cognitive Behavioral Therapy (CBT), holistic/herbal medicine, exercise/yoga, and diet and dietary supplements. More research on gender differences in ADHD could decrease the misdiagnosis of women who have ADHD and offer more treatment options once a diagnosis is made.

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
Multiple sclerosis is currently deemed the most common autoimmune disease. By definition, multiple sclerosis, known more commonly as MS, involves an immune-mediated process in which an abnormal response of the body’s immune system is directed against the central nervous system (“Definition of MS,” n.d.). Common treatment protocols call for daily, monthly, or yearly disease-modifying medications. These drugs are taken indefinitely to stop the spread and appearance of new lesions, improve symptoms, and offer relief to the afflicted individuals. The necessity for patients to take these basic medical treatments is paramount, however, it should not be overlooked to make lifestyle changes as well. The purpose of this paper is to give a detailed understanding of multiple sclerosis, its etiology evolution, and medical advancements, while emphasizing the necessary transitions which must be made from a nutritional and lifestyle management standpoint. A brief focus will be placed on sleep, exercise, and stress management, with an emphasis on nutrition.

Description
The purpose of this project is to present research within three main categories of treatment and care such as exercise, socialization and alternative therapies (art, pet, and reminiscent therapies) for Alzheimer’s Disease (AD). These categories will be examined in the following countries: United Kingdom, United States, Brazil, and China. Then, the synthesized material will be analyzed and placed into a comparison and contrast model showcasing what each country is currently using and the success of the particular resource within a heat map. According to the research found on the following categories of exercise, socialization and alternative therapies, I will conclude that a combination of aerobic and resistance training, routine support groups and art/pet therapies are the most effective treatment options against Alzheimer’s Disease.

Description
Swing dancing is a form of partnered dancing that has a focus on social interactions. The purpose of this study is to determine how social factors and intrinsic motivation effect how college age students perceive how much energy exertion swing dancing requires compared to traditional exercise. 20 ASU students were split into 10 female-male couples. The participants first completed a 30-minute session of social dancing and then a week later completed a 30-minute session of cycling on a stationary bike. Physiological data was collected using a Polar heart rate (HR) monitor wristwatch and chest strap. The HR of participants was taken after a period of rest and every five minutes during swing dancing and cycling. The rate of perceived exertion (RPE) was measured based on a Borg scale (6-20). RPE was taken after a period of rest and every five minutes during swing dancing and cycling. After both physiological sessions a psychological survey was distributed measuring the social factors of dancing, the intrinsic motivation of dancing, and the intrinsic motivation of traditional exercise. There was no significant difference between average HR during rest (p=0.34) or during the two types of exercises (p=0.26). There also was no significant difference in RPE during rest (p=0.33) or during the two types of exercises (p=0.46). At the same intensity participants perceived swing dancing to require as much energy exertion as cycling. Participants were significantly more intrinsically motivated to swing dance compared to traditional exercise. Participants reported high levels of social factors while swing dancing and these social factors had a moderately positive effect on intrinsic motivation for swing dancing. People are more intrinsically motivated to engage in swing dancing over traditional exercise and this may be due to the high social factors found in partnered dancing. Swing dancing is a form of exercise that can be used to reach the recommended level of physical activity.

Description
According to the CDC, obesity has increased from 30.5% to 42.4% over the past 18 years. Western diets (WDs) consist of large portions in high fats, high carbohydrates, excess sugar and high-glycemic foods that can cause metabolic complications and mitochondrial dysfunction. Diet-induced obesity can lead to changes in muscle metabolism and muscle fiber phenotypes, which in turn lead to metabolic complications. Muscle fiber phenotype is determined protein isoform-content of myosin heavy chain (MHC). Regular exercise alters mitochondrial content and fat oxidation and shifts MHC proportions under healthy circumstances. However, diet and exercise-driven fiber type shifts in diet-induced obesity are less understood. We designed our experiment to better understand the impact of diet and/ or exercise on fiber type content of gastrocnemius muscle in diet-induced obese mice. Exercise and genistein may be used as a treatment strategy to restore the MHC proportions in obese subjects to that of the lean subjects. We hypothesized that genistein and exercise would have the greatest MHC I change in muscle fiber phenotype of mouse gastrocnemius muscles. Further, we also hypothesized that a standard diet would reverse the expected increase in fast fiber phenotype (MHC IIb). Lastly, we also hypothesized that exercise would also reduce the abundance of MHC IIb. Gastrocnemius muscles were collected from mice, homogenized, run through gel electrophoresis and stained to give muscle fiber proportions. Paired sample t-tests were conducted for differences between the MHC isoforms compared to the lean (LN) and high-fat diet (HFD) control groups. The results showed that genistein and exercise significantly increased the abundance of MHC I muscle fibers (19%, p<0.05). Additionally, diet and exercise restored the muscle fiber phenotype to that of lean control. As expected, HFD obese mice exhibited elevated fast twitch fibers compared to only 3% slow twitch fibers. These findings show the potential for exercise and supplementation of genistein as a strategy to combat diet induced obesity. Future research should aim to understand the mechanisms that genistein acts on to make these changes, and aim to replicate these data in humans with obesity.
