Comparison Of Dual- And Tri-Axial Accelerometer Accuracy, Lindsay Powell Toth

Masters Theses

The purpose of this study was to investigate the accuracy of the Omron HJ-720ITC and the Fitbit Zip activity monitors with regard to step count, energy expenditure, and distance traveled measurements. The importance of this research rests in the success rates of pedometer-based physical activity interventions which have been shown to increase physical activity while also enabling weight loss and lowering blood pressure in the adult population. Activity monitors available for retail sale must be found accurate for proper participation in exercise interventions especially low-cost devices as used in this study.

In order to test the accuracy of the Omron …

Improving Consistency Of Goal Attainment To Increase Physical Activity, Elizabeth Anne Solley

USF Tampa Graduate Theses and Dissertations

Researchers have successfully increased physical activity with self-monitoring, goal setting, and feedback. Goal attainment is a crucial part of what makes goal setting successful; however, it is often unreported in the literature or implied that goals were not reached consistently. A potential way to achieve this consistency is to create an action plan, or a detailed account of exactly how and when the individual will engage in the desired physical activity to reach his or her goal. This study evaluated whether making a detailed action plan would allow individuals to reach their physical activity goals more consistently than when using …

Calibration Of Built-In Accelerometer Using A Commercially Available Smartphone, Jung-Min Lee, Youngwon Kim, Yi-Suk Kwon, Timothy R. Derrick, Gregory J. Welk

Research Presentations

Wearable trackers that detect sleep offer users a way to track their sleep quality and patterns without the use of expensive equipment. Few studies have tested the validity of these trackers on sleep measure. PURPOSE: To examine the validity of the Actigraph GT9X (AG), SenseWear Mini Armband (SW), Basis Peak (BP), Fitbit Charge HR (FB), Jawbone UP3 (JU), and Garmin Vivosmart (GV) for estimating sleep variables as compared with a sleep diary. METHODS: 78 healthy individuals participated in the study. Group 1 (n= 38) and wore the AG, SW, BP, and FB or Group 2 (n = 40) …

Quantification Of Eccentric Load Using Accelerometer Imbedded In Gps, Chow Chea Yeo

Theses: Doctorates and Masters

Global positioning system (GPS) with a triaxial accelerometer is widely used to monitor movements of athletes in games and training, and “body load” (BL) representing the accumulation of the rate of changes in three planes of movements is obtained to determine the training load of a session. Deceleration, change of directions and stopping require eccentric contractions of leg muscles, potentially causing muscle damage and affecting athletic performance. Thus, it is important to monitor eccentric loading in games and training. A variable known as “eccentric index” (EI) purports to be a better representation of eccentric loading than BL. However, it is …
