A Novel Item-Allocation Procedure For The Three-Form Planned Missing Data Design, Kyle M. Lang, E. Whitney G. Moore, Elizabeth M. Grandfield

Kinesiology, Health and Sport Studies

We propose a new method of constructing questionnaire forms in the three-form planned missing data design (PMDD). The random item allocation (RIA) procedure that we propose promises to dramatically simplify the process of implementing three-form PMDDs without compromising statistical performance. Our method is a stochastic approximation to the currently recommended approach of deterministically spreading a scale's items across the X-, A-, B-, and C-blocks when allocating the items in a three-form design. Direct empirical support for the performance of our method is only available for scales containing at least 12 items, so we also propose a modified approach for use …

How Exercise Impacts The Brain And Cognition, Cody Larson

Biology and Microbiology Graduate Students Plan B Research Projects

Physical exercise has been shown to impact the brains composition and functionality. The changes that arise in the structure of brain, as result of engaging in physical exercise, give rise to cognitive changes. Structural changes are observed most notably in the prefrontal cortex and hippocampus. These changes are preceded by elevations in cerebral blood flow, and growth factors, resulting increased neuroplasticity and neurogenesis. Frequency, duration, intensity, and type of physical exercise can have differing effects on the brain. Moderate intensity aerobic exercise presents the most profound improvements in memory, and inhibitory control over time.

Energy Compensation With Exercise Is Not Dependent On Dose, H. Michael Hays

Theses and Dissertations--Nutrition and Food Systems

Background: Exercise induced weight loss is often less than expected due to a coordinated set of compensatory mechanisms that serve to maintain energy homeostasis. The extent to which exercise frequency, duration, intensity and exercise energy expenditure (ExEE) influences the compensatory response to an exercise-induced energy deficit (energy compensation) is controversial. Determining how these variables impact energy compensation would help health care providers prescribe exercise with greater probability of creating a sustained negative energy balance and subsequent weight loss.

Methods: 44 Overweight/obese men and women (BMI=25-35kg/m²) aged 18 to 40 years were randomized to perform aerobic exercise 2 or 6 days/week …
