Description
The aim of this case study was to help MH, a young adult male with Down syndrome, lose weight and improve his health. Initially he was morbidly obese, suffering from physical, mental, emotional, and health-related side effects. MH and his mother requested help from Dr. Shannon Ringenbach, and resided in Arizona for four months during the process of developing and implementing a program of diet and exercise for him. We created a plan to maximize weight loss in this short period of time. Overall, MH reduced his weight from 276 lbs. to 217 lbs. in four months, his lowest weight being 201 lbs. after he and his mother returned home to Oregon. This is a 75 lb. weight loss and body mass index (BMI) reduction of 13.7 kg/m2. Although to reach a healthy body weight MH would still need to continue his weight loss, this is a significant amount of weight, which is especially difficult for people with Down syndrome to lose. In this case study it was crucial to take into consideration the other aspects that affect weight gain and loss, such as motivation, family life, diet, and lifestyle.

Description
Color is an inseparable part of our world as it exists in everything we perceive (Hemphill, 1996). With this constant exposure to colors, it has been widely acknowledged that colors have a distinct effect on a person's feelings and emotions (Hemphill, 1996). In fact, researcher have found that color perception evolved as an adaptation to increase fitness for animals (Bryne & Hilbert, 2003). For humans, color is a part of many everyday associations from temperature to traffic lights to sporting events. Taking this a step further, researchers have studied the effects of color on psychological functioning and physiological responses, including anxiety. A substantial body of research developed a base of information to support the idea that color has a significant effect on humans' emotions, perceptions and behaviors. I set out to test the effects of color on test anxiety and the relationship between anxiety and test performance. It was hypothesized that paper colors red, blue, and green would have an effect on anxiety with red having the most robust effect. It was also hypothesized that there would be a correlation between test performance and anxiety. Fifty undergraduate students took a ten-question brainteaser test printed on one of the three paper colors. Results displayed a significant mead difference between the three test group colors and a significant correlation between test performance and anxiety. This study was then repeated using the colors white, blue, and red. Fifty-eight undergraduate students took the same ten-question brainteaser test. These results failed to suggest a significant mean difference between the three test groups and failed to suggest a correlation between performance and anxiety. These findings conflict with the first study, and therefore, are of interest. Possibilities for these findings are the frequency of occurrence of white and social desirability. Future directions include testing for trait anxiety prior to data collection and using physiological measures to test anxiety. Still, these results can be applied in classroom settings, office environments, and airports.

Description
Persons with Down Syndrome (DS) have been repeatedly shown to have timing deficits, to move slowly, and to not follow metronomes. This timing deficit in persons with DS requires further study because timing is fundamental to movement control. Furthermore, brain imaging studies have proposed a rate effect in which increased cortical activation in the primary motor cortex was observed during increased finger movement frequency. The aim of the current study was to determine if the rate effect was present in persons with DS by comparing brain activation in self-selected and as fast as possible rates. Eight participants with DS performed unimanual drumming at their self-selected and maximal rates. Movement rate was measured at EEG was collected in the alpha (8-12 Hz) and Beta (13-30 Hz) frequencies from C3 and C4. The results showed that overall, their self-selected rates were slower than their maximal rates, indicating that they are capable of modifying their movement rate with general instructions. Furthermore, there were significant differences in Beta in which there was more activation during as fast as possible than self-selected tapping in both sides of the primary motor cortex in persons with DS. This suggests that their brains are activated in a similar manner as the typical population with respect to movement rate. Overall, our results suggest that while interventions that involve timing to specific rates are difficult, people with DS can perform at self-selected and maximal rates. The results of our study show that they can alter movement rate when provided with general instruction or additional motivation.

Description
Dancers tend to injure the anterior cruciate ligament in their left leg more often than the right. It is unclear whether this trend is due to biased choreography or if leg dominance and left versus right asymmetries are contributing factors. The purpose of this study was to investigate asymmetries between the left and right leg, in knee abduction during landing, hip external rotation (ER) and internal rotation (IR) strength, and hip ER and IR range of motion in dancers compared to non-dancers. This study aimed to determine whether these asymmetries can be linked to leg dominance, and if this puts one leg at higher risk for ACL injury. Ten dancers and eleven non-dancers performed three maximal effort countermovement vertical jumps off of two feet, as well as three maximal effort single leg jumps on each leg. Knee abduction angles during the landing phase of the jumps were calculated using motion capture data. Maximum isometric hip ER and IR strength was measured at 15, 30, 45, 60, and 90 of knee flexion, and hip ER and IR range of motion was measured at 90 of knee flexion. Contrary to the hypothesis, few significant differences were found between the left and right leg, as well as between dancers and non-dancers. Dancers exhibited significantly greater IR range of motion than non-dancers, and knee abduction angles were greater on the right than left leg during double leg jumps. This opposes the hypothesis that knee abduction angles would be greater in dancers on the left leg. However, significant positive correlations were found
between IR strength and knee abduction angles during single leg jumps on the left leg, suggesting that IR strength may be a contributing factor to knee valgus. Further studies may want to utilize qualitative analyses, more relevant jumping tasks, and a different marker set to elucidate asymmetries of the lower limbs that may truly be present.

Description
High fat diets (HFD) are known to cause hepatic non-alcoholic steatosis in rats in as few as four weeks. Accumulation of triglycerides in liver and skeletal muscle is associated with insulin resistance and obesity. However, studies of fat accumulation in cardiac muscle are not as prevalent. Therefore, the first hypothesis of this study was that HFD would lead to hepatic steatosis as well as lipid accumulation in pectoralis and cardiac muscles, tissues responsible for the majority of postprandial glucose disposal. Prior studies also indicated that HFD leads to increased inflammation and oxidative stress within the vasculature resulting in impaired endothelium-dependent vasodilation, however biomarkers of immune system reactivity were not assessed. Therefore, the second aim of this study was to explore additional pathways of immune system reactivity and stress (natural antibodies; heat shock protein 60 (HSP60)) in rats fed either a control (chow) or high fat (HFD) diet. HSP60 has also recently been recognized as an early marker of vascular dysfunction in humans. The hypothesis was that immune system reactivity and early vascular dysfunction would be heightened in rats fed a HFD compared to chow-fed controls. Young male Sprague-Dawley rats (140-160g) were maintained on a chow diet (5% fat, 57.33% carbohydrate, 3.4kcal/g) or HFD (60% fat, 20% carbohydrate, 5.24 kcal/g) for 6 weeks. HFD rats developed hepatic steatosis with significantly elevated liver triglyceride concentrations compared to chow-fed controls (20.73±2.09 vs.9.75±0.52 mg triglycerides/g tissue, respectively; p=0.001). While lipid accumulation appeared to be evident in the pectoralis muscle from HFD rats, triglyceride concentrations were not significantly different from controls. Likewise, there was no evidence of lipid infiltration in cardiac muscles of HFD rats. Lipid accumulation in the liver of overweight HFD rats may contribute to the observed insulin resistance in these animals. Contrary to the second hypothesis, there were no significant differences in plasma HSP60 expression between HFD and chow rats (p>0.05). Likewise, hemagglutination and hemolysis responses were similar between HFD and chow-fed rats (p>0.05). These findings suggest that immune system responses may not be affected by 6 weeks of high fat intake and that HSP60 is not an early marker of vascular dysfunction in this rodent model.

Description
Problem: Overweight and obesity are global issues. There are several strategies for weight loss and maintenance as well as general lifestyle change for overall better health. The goal is to find an easy and convenient way for people to track their food intake, either for personal use and improvement, or to be used by professionals such as registered dietitians to gather data and help improve diet. Currently food journals, food frequency questionnaires and 24-hour recall are methods that are used by registered dietitians to get an idea of what is general diet is like from their patients or clients. It was proposed that pictures taken of the meal with a phone could be used as a method of recording food intake. It would be quick and extremely easy on the client; then everything from portion size, to type of food and toppings could be analyzed quickly and conveniently. If effective it could also give rise to the ability for foods to be analyzed immediately with the text or email of the picture. Methods: subjects already participating in a separate study where they were instructed to take pictures of their meals for a difference purpose were recruited. There recorded diet intake with phone pictures were able to be used from seven subjects. Subjects took a snapshot of their meals for 3 separate days and also logged on and completed a 24 hour recall with the ASA website. The pictures were analyzed and food intake, based off the pictures was entered in the program Food Processor to generate a nutritional report. The results from the ASA 24 hour recall, based on what the subject entered, were compared to the nutritional report, generated based on review of the pictures. Nutrient values that were compared include: total energy intake (calories), protein, carbohydrates, fat, vitamin C, calcium and fiber. This was done to test if the pictures could be used as a valid source. Results: It was found that there were several problems with using the pictures as a method of analyzing food intake. Out of the seven subjects the result of only one subject was close between the two methods. All other results of calculated nutrient intake varied significantly and it did not prove to be effective to use pictures to analyze food intake. Conclusions: food intake recorded by picture method may prove to be useful in the future, however there would need to be greater compliance and training on picturing food that can be accurately analyzed. Short written explanation of food type and cooking method etc. would be most beneficial to include with actual picture. Pictures of food intake may be useful in other professional areas but as of now are not useful to generate nutritional reports.

Description
The Gluten-Free Diet (GFD) is increasing in prevalence due to increased diagnoses of Celiac Disease, however deficiencies have been found to persist in individuals with Celiac Disease who have been on the diet for a prolonged period of time. These deficiencies are not the result of continued GI inability to absorb the nutrients (as evidenced by biopsy) and, therefore, are inherent to the diet itself. Comparing these deficiencies to nutrient-dense gluten-free grains reveals those that specifically meet the deficiencies evident in the GFD. These include low-fat soy flour, buckwheat, and sorghum as the most nutritionally adequate for the gluten-free individual.

Description
The aim of this study is to evaluate whether or not fitness can be determined using a well-researched six minute walk test (6MWT) in a young adult population with Down syndrome (DS). This holds importance in today's health industry because this particular target group is at high risk for several cardiovascular, cognitive and clinical factors that contribute to their well-being and longevity. As well, the findings of this research could potentially contribute to the low volume of research that currently exists regarding fitness and the DS population and provide pertinent knowledge towards intervention programs. Fourteen participants with DS performed one 6MWT at a self-selected rate during an exercise intervention study to assess physical fitness. The results showed that walk distance increased with decreased BMI and walk distance increased with increased walking speed and increased leisure activity. These findings are clear indicators of physical fitness relating to healthy physical behavior. All results were consistent with past research in specific at-risk health related populations. This data suggests that this physical test is an adequate indicator of fitness levels in populations with DS, which may additionally provide explicit avenues for intervention and treatment to improve health.

Description
The aim of this study is to understand the affects of grip strength and manual dexterity in activities of daily living (ADL) in persons with Down syndrome (DS). This is important because it could help with future interventions that are focused around improving related disadvantages in this particular population. Ten participants with DS performed the manual dexterity tests (i.e., Purdue Pegboard) and measured their grip strength with a hydraulic dynamometer. Overall, grip strength was lower than the average for the typical population and was reduced after aeorbic exercise. Improvements, however, were found in their manual dexterity from pre-test to post-test. This indicates that the assisted moderate intensity exercise intervention helped their dexterity performance. The improvements in dexterity are consistent with previous research conducted by Ringenbach et al. (2007). These results suggest that a moderate intensity treadmill walking exercise intervention can increase precision and efficiency in dexterity in persons with Down syndrome, however their grip force production may be stimulated by another means.

Description
My intention with this project was multifaceted; my goal was to articulate in words and share through physical embodiment what dance means to me and how dance has helped shape me as an individual. In doing so, I delved into an exploration of defining dance and its role within my life and in society at large. Inspired by the black and white, silent film The Artist, I began pondering how important external elements such as music, lighting, and color are when choreographing work and furthermore sharing it with an audience. For most mainstream concert dance choreographers, these elements are an integral part of the artistic process and factor into the totality of a performance experience as a work comes into fruition. The title of my thesis, A Composition of Dance, is a play on words in my attempt to challenge my own notion of dance and investigate how one's senses and environment can influence one's perception of dance from both the performer and audience perspective.
