Item Comparison of selected micronutrient intakes between flexible dieting and strict dieting bodybuilders.(2017-03-31) Ismaeel, Ahmed, 1993-; Weems, Mary Kate Halbert (Suzy).The purpose of this study was to provide a descriptive assessment of the nutritional habits of competitive bodybuilders, specifically in relation to vitamin and mineral intakes. Data from 41 subjects (30 males and 11 females) were used in analyses. Participants completed a comprehensive food frequency questionnaire and diets were analyzed using a computer system. Males consumed less than the RDA of vitamin A, vitamin D, vitamin E, potassium, and dietary fiber. Females consumed less than the RDA for vitamin A, vitamin D, vitamin E, potassium, dietary fiber, and iron. There were no significant differences between male flexible and strict dieting bodybuilders when mean nutrient intakes were compared. For females, flexible dieters consumed significantly greater amounts of several nutrients. A large proportion of individuals from all groups consumed less than the recommended amounts of several of the micronutrients. Therefore, competitive bodybuilders should be advised to take their micronutrition into greater consideration.Item Determining the relative validity of a short screener for assessing adherence to a modified Mediterranean diet in cardiopulmonary rehabilitation patients.(2017-07-29) Lyles, Patricia J., 1990-; Weems, Mary Kate Halbert (Suzy).The purpose of the study was to determine the relative validity of a short screener used to assess dietary compliance to a modified Mediterranean diet in a cardiopulmonary rehabilitation program. Thirty-one participants completed a newly developed short screener in the clinic and an at-home seven-day food journal that was used as a reference to explore validity. A survey was designed and completed by five Registered Dietitians to assess face validity of the screener. Descriptive statistics were used to analyze and compare the differences of the reported answer frequencies between both measurement tools. The results of the face validity survey and descriptive statistics determined the screener was not valid. Since the study was a pilot study, the statistical methods used to analyze the data were mainly used as a preliminary way to assess the relative validity. In conclusion, future research should address and implement the necessary changes to improve validation.
