Short-term Changes in Objectively Assessed Step-defined Physical Activity in The Wave~Ripples for Change: Obesity Prevention in Active Youth Study

Creator:: Le, Kevin and Schuna, John M., Jr.
Abstract:: The WAVE study is an on-going multicomponent comparative-effectiveness trial aimed at improving nutritional habits, increasing habitual physical activity, and preventing unhealthy changes in body composition among active 14-19 year-old adolescents. Participants were recruited through soccer teams from 13 schools and enrolled in one of two conditions: 1) a novel and...

Associations Between the PlayerLoad™ Metric and Common IMU-based Physical Activity-Related Measures of Human Movement

Creator:: Dailey, Dakota B.
Abstract:: Over the last 60 years, supplemental strength and conditioning for improving sport performance has gone from being nearly non-existent to a cornerstone feature of elite collegiate, amateur, and professional athletics. Concurrent with this profession-related evolution, technologies for monitoring and tracking physical performance have become more prevalent and useful. As an...

Identifying Threshold Values of Accelerometer-Determined Moderate-to-Vigorous Physical Activity that Correspond to Self-Reported Compliance to the 2008 Physical Activity Guidelines for Americans : National Health and Nutrition Examination Survey 2003-2006

Creator:: Brier, Julie A.
Abstract:: Current public health guidelines for physical activity (PA) were primarily formulated using evidence collected from a series of prospective cohort epidemiological investigations that measured self-reported PA. In light of this observation, and the known discordance between self-reported and objectively-monitored PA, it remains common for researchers to assess compliance to current...

Validity and Reliability of the Unsupervised, Isokinetic Three-Minute All-Out Cycling Test for Critical Power

Creator:: Bronson, Staci M.
Abstract:: PURPOSE: We tested the hypothesis that the unsupervised, isokinetic 3- minute all-out cycling test (3MT) would be a valid and reliable way to determine end power (EP) and work done above end power (WEP). Additionally, we hypothesized that EP would successfully demarcate between heavy and severe-intensity exercise and thus represent...

Comparison of Relationship between Accelerometer Outputs and Energy Expenditures in People with and without Down syndrome during Walking Activity

Creator:: Leung, Chun (Willie)
Abstract:: In recent years, there has been an increased interest in accurately measuring physical activity levels with accelerometers. Two distinct approaches have been used to estimate physical activity levels with accelerometers are vertical axis activity counts and vector magnitude (VM). Although previous studies evaluated these two distinct approaches for individuals without...

The Relationship Between Force Plate Derived Eccentric Rate of Force Development and ELEIKO Vmaxpro Derived Eccentric Motion Rate of Force Development

Creator:: McCarthy, Benjamin
Abstract:: Eccentric rate of force development (ECC RFD) is a measure of the rate at which muscles can generate decelerative forces. However, it has traditionally been measured while jumping on force plates, which are not easily accessible or easy to use in a practical setting. With technology advancements it may be...

Creator:: Tudor-Locke, Catrine, Barreira, Tiago V., Schuna, John M., Jr., and et al.
Abstract:: BACKGROUND: We compared 24-hour waist-worn accelerometer wear time characteristics of 9-11 year old children in the International Study of Childhood Obesity, Lifestyle and the Environment (ISCOLE) to similarly aged U.S. children providing waking-hours waist-worn accelerometer data in the 2003-2006 National Health and Nutrition Examination Survey (NHANES). METHODS: Valid cases were...

Wearable Device Users with and without Disabilities and their Physical Activity Behaviors

Creator:: Leung, Willie C.
Abstract:: The importance of physical activity is well documented (Haskell et al., 2009a; McReynolds & Rossen, 2004; Steinbeck, 2001). Despite physical activity’s benefits, many individuals are not meeting current weekly physical activity guidelines recommending ≥ 150 minutes of moderate or ≥ 75 minutes of vigorous aerobic physical activity and 2 or...

Assessing Between-day and Inter-rater Reliability of a 3-minute Running Test for Determining Critical Speed

Creator:: Arakawa, Lee
Abstract:: For athletes and training populations, the ability to track progress and determine appropriate workloads to stimulate adaptation is vital. Measures that represent a person’s aerobic fitness such as VO2 max and blood lactate concentration are often used for these purposes. While these measures can reveal a lot about a person’s...
