Behavioral Determinants Of Exercise-Related Injury Prevention Program Participation, Emily M. Hartley

Health Services Research Dissertations

Lower extremity injuries are common among the physically active population. There are many negative consequences associated with these injuries which have led to a shift in clinical practice towards prevention. Exercise-related injury prevention programs (ERIPPs) were created to prevent musculoskeletal injuries that occur due to participation in physical activity. However, one of the major limitations to their effectiveness is the compliance of the users to complete the prescribed exercises. It is imperative to better understand the reasons why compliance is low to develop implementation strategies and improve compliance rates.

The overarching purpose of this dissertation was to gain a better …

The Relationship Between Linear And Nonlinear Analysis On Activity Data, Katlyn J. Nimtz

UNO Student Research and Creative Activity Fair

Activity monitoring in older adults is a great way to predict disability without interfering in their daily life. We can analyze that data using linear and nonlinear analysis. While linear analysis measures the variation of activity during a specific period of time (i.e., mean, standard deviation), nonlinear analysis focuses on the evolution of activity over a period of time. Therefore, the purpose of this study was to observe the relationship between linear and nonlinear analysis of activity data obtained by activity monitoring in older adults. Eight participants wore an activity monitor around their waist for seven days. Linear analysis was …

Comprehensive school physical activity programs (CSPAPs) have been endorsed as a promising strategy to increase youth physical activity (PA) in school settings. A CSPAP is a five-component approach, which includes opportunities before, during, and after school for PA. Extensive resources are available to public health practitioners and school officials regarding what should be implemented, but little guidance and few resources are available regarding how to effectively implement a CSPAP. Implementation science provides a number of conceptual frameworks that can guide implementation of a CSPAP, but few published studies have employed an implementation science framework to a CSPAP. Therefore, we developed …

Repeatability Of The Heart Rate Variability Threshold During Treadmill Exercise, Shane Chambers 2018 James Madison University

Repeatability Of The Heart Rate Variability Threshold During Treadmill Exercise, Shane Chambers

Senior Honors Projects, 2010-2019

Purpose: Heart rate variability threshold (HRVT) is a clinical parameter used to gain insight into autonomic balance. Various studies have validated the use of cycle ergometers in determining HRVT, although the literature lacks evidence that treadmill use is a viable means of determining this threshold. We examined the repeatability of HRVT occurrence using standard deviation of normal R-R intervals (SDNN), root mean square of successive differences of continuous R-R intervals (RMSSD), and standard deviation of instantaneous beat intervals (SD1) in college aged males using treadmill exercise to see if this is a reliable method of threshold determination.

Methods: Ten healthy, …
