This article compares four mixed-model analyses valid for group-randomized trials (GRTs) involving a nested cohort design with a single pretest and posttest. This study makes estimates of intraclass correlations (ICCs) available to investigators planning GRTs addressing dietary outcomes. It also provides formulae demonstrating the potential benefits to the standard error of the intervention effect (σΔ) from adjustments for both fixed and time-varying covariates and correlations over time. These estimates will allow other researchers to use these variables to plan their studies by estimating a priori detectable differences and sample size requirements for any of the four analytic options. These methods …

A Schematic For Focusing On Youth In Investigations Of Community Design And Physical Activity, Kevin J. Krizek, Amanda Birnbaum, David M. Levinson
A Schematic For Focusing On Youth In Investigations Of Community Design And Physical Activity, Kevin J. Krizek, Amanda Birnbaum, David M. Levinson

This paper provides a first step in addressing special considerations for youth in a relatively new area of physical activity research. After reviewing the urgent need for novel approaches to increasing physical activity, the growing interest in the effects of community design are discussed. Although most discussion on this topic has focused on adults, there are important differences between youth and adults that warrant a special focus on youth and need to be accounted for. This article presents a schematic that accounts for how and where youth spend their time, decomposing the day into time spent in travel and time …
The Effects Of Music Preference And Exercise Intensity On Exercise Enjoyment And Perceived Exertion, Allison Dyrlund
The Effects Of Music Preference And Exercise Intensity On Exercise Enjoyment And Perceived Exertion, Allison Dyrlund
Masters Theses & Specialist Projects
In spite of the well-known physical and psychological benefits of exercise roughly 50% of people who start an exercise program will have dropped out within six months. Therefore, it is important to examine the determinants of exercise adherence. Past research has shown that enjoyment is an essential factor in exercise adherence. Additionally, music has been shown to influence exercise enjoyment. The music and enjoyment literature has generally included most preferred and no music conditions, yet no one has considered a least preferred music condition. Therefore, the purpose of this study is to examine the effects of music preference and exercise …

Qtc Is Associated With Obesity And Physical Activity Level For African American Females, C. Jayne Brahler
Qtc Is Associated With Obesity And Physical Activity Level For African American Females, C. Jayne Brahler
Health and Sport Science Faculty Publications
Long QT syndrome (LQTS) is an independent risk factor for cardiovascular or ischemic disease mortality. Obesity as a cause for acquired LQTS in otherwise healthy individuals is rapidly gaining the attention of the scientific community. African American people have a higher incidence of obesity compared to Caucasians, yet race-specific information is not available for their prevalence of LQTS. Chronic physical activity can help reduce the incidence of obesity, yet little is known about the effects of chronic physical activity on acquired LQTS. Subjects in this study were a volunteer sample of African American mothers (21-53 yr, n = 44) and …

Intra-Arterial Blood Pressure Characteristics During Submaximal Cycling And Recovery, Julia Orri, S E. Griffin, Robert A. Robergs, David S. James, D R. Wagner, R Quintana
Kinesiology (Formerly Exercise and Sport Science)
The purpose of this study was to measure intra-arterial (IA) blood pressure from rest to steady-state submaximal exercise and immediately post-exercise. Beat-to-beat blood pressure was compared to breath-by-breath VO2 during steady-state and maximal exercise. Fourteen normotensive subjects volunteered. Systolic (SBP), diastolic (DBP) and mean (mBP) blood pressure was measured from rest to steady state during cycling at 45, 60, and 75% maximal power output (POmax). BP was assessed during recovery from VO2peak through 2 min of cycling at 50 W. During the rest to exercise transition, mBP decreased from 103.41 ± 9.4 to 90.1 ± 8.9 mmHg after 11.6 ± …
