Physical Activity, Sleep Patterns, And Health Outcomes In University Law Enforcement Officers, Nicole C. Koebke Jan 2012

Physical Activity, Sleep Patterns, And Health Outcomes In University Law Enforcement Officers, Nicole C. Koebke

Theses and Dissertations--Kinesiology and Health Promotion

Research indicates that law enforcement officers (LEOs) have a higher prevalence of developing coronary artery disease (CAD) compared to the general population. Sleep deprivation and physical inactivity have been found to be related to many risk factors for CAD. This cross-sectional study examined the health status and the relationship between sleep and physical activity outcomes versus CAD risk factors among 27 University LEOs. The subjects’ health behaviors, and CAD and metabolic syndrome risk factors were described using basic statistics. Accelerometer derived sleep and physical activity outcomes were correlated to measures of health to identify potential relationships. 33% of LEOs were …


Changes In Bone Mineral Density In Middle-Age Women According To Physical Activity Volume, Intensity, And Cardiorespiratory Fitness: A Six-Year Prospective Study, Neil R. Nokes Aug 2009

Changes In Bone Mineral Density In Middle-Age Women According To Physical Activity Volume, Intensity, And Cardiorespiratory Fitness: A Six-Year Prospective Study, Neil R. Nokes

Theses and Dissertations

This study was conducted to determine if physical activity and cardiorespiratory fitness (CRF) at baseline influence the likelihood of gaining bone mineral density (BMD) at the hip and lumbar spine over 6 years. Another aim was to ascertain the effect of several potential confounding factors. In a prospective study of 244 women (baseline age range 35-45 years), physical activity volume (PAv) and intensity (PAi) were measured using accelerometers at baseline. CRF indexed by VO2max was estimated using a graded, maximal treadmill test at baseline. BMD was measured using DEXA. Risk ratios were used to show the likelihood of BMD gains …


Time Efficiency In Computer Assisted Direct Observation Of Physical Activity Using Sofit, Trisha Anderson Jul 2005

Time Efficiency In Computer Assisted Direct Observation Of Physical Activity Using Sofit, Trisha Anderson

Theses and Dissertations

Having valid and reliable methods for assessing physical activity levels is critical to understanding physical activity patterns. Direct observation is a widely used technique for obtaining contextually rich data on physical activity levels in physical education classes. One major limitation of direct observation is that it is time intensive. The use of digital video editing software programs may lessen the amount of time needed to gather the data. The purpose of this study was to compare the amount of time needed to obtain SOFIT (System for Observing Fitness Instruction Time) physical activity data using the traditional paper and pencil method …
