Validity Of The Yale Physical Activity Survey For Older Adults, Angela Nickole Solomito Pugh
Validity Of The Yale Physical Activity Survey For Older Adults, Angela Nickole Solomito Pugh
LSU Master's Theses
The purpose of this study is to determine the validity of the Yale Physical Activity Survey (YPAS) in a population of oldest-old adults residing in Southeastern Louisiana. Methods: Participants were older adults (n=273) in two distinct age groups; 60-81 years of age (YOUNG-OLD) AND 29-103 years of age (OLDEST-OLD). YPAS estimates of physical activity will be compared to physical function as measured by the continuous scale physical function performance test. Results: The OLDEST-OLD demonstrated lower physical function scores and reported less physical activity (and more time sitting) in comparison to the YOUNG-OLD. The correlation between Total Time Summary Index and …
Examination Of Blood Flow Using Vasoconstrictor And Vasodilator Stimuli: Stability And Reproducibility, Robert B. Lestage
Examination Of Blood Flow Using Vasoconstrictor And Vasodilator Stimuli: Stability And Reproducibility, Robert B. Lestage
LSU Master's Theses
Blood flow distribution relies on the vasculature’s ability to vasodilate and vasoconstrict throughout the body. Most previous research has focused on only one of these abilities, either vasodilation or vasoconstriction. For example, Thijssen et al. (2005) focused their research on vasodilation by studying reactive hyperemia, while Kinuyoshi et al. (2003) studied the possible vasoconstriction effect with increasing muscle sympathetic nerve activity. The purpose of this study was to assess vascular function using a variety of stimuli to potentially learn more about overall vascular health, while determining the stability and reliability of blood flow measurements using strain gauge plethysmography. Measures of …
Understanding Parents' Decisions About Serving Vegetables To Their Children, Alissa Villarrubia
Understanding Parents' Decisions About Serving Vegetables To Their Children, Alissa Villarrubia
LSU Master's Theses
With the increasing rate of childhood obesity it is important to examine obesity prevention programs and strategies. The theory of planned behavior (TPB) has been identified as a successful framework to examine and understand human behavior and obesity prevention research. However, there is limited support for the TPB regarding its use and efficacy for understanding parents’ influence on the health behavior of their children. The purpose of this study was to: (a) describe the most common behavioral, normative, and control beliefs of parents’ serving vegetables to their children; (b) examine the social cognitive correlates of parents’ intentions to serve vegetables …
Interrelationships Between Mitochondrial Function, Maximal Oxygen Consumption, Running Economy, And Diet In Elite Male And Female Runners, Ryan Peyton Mcmillan
Interrelationships Between Mitochondrial Function, Maximal Oxygen Consumption, Running Economy, And Diet In Elite Male And Female Runners, Ryan Peyton Mcmillan
LSU Master's Theses
The relationships between maximal oxygen consumption (VO2max), mitochondrial function and running economy were investigated in a population of twenty-one endurance trained males and females (range=18-54 yrs). The purposes of this study were: 1) to determine whether mitochondrial oxidative capacity, as defined by the maximal activities of citrate synthase (CS), cytochrome c oxidase (COX), and beta-hydroxyacyl-CoA dehydrogenase (BHAD), is a significant determinant of maximal oxygen consumption in endurance trained men and women, and 2) to observe the relationship between maximal oxygen uptake and running economy in the same population. Muscle biopsy samples were taken from the vastus lateralis prior to a …
