Validity Parameters For Step Counting Wearable Technologies During Treadmill Walking In Young People 6-20 Years Of Age, Zachary Gould
Validity Parameters For Step Counting Wearable Technologies During Treadmill Walking In Young People 6-20 Years Of Age, Zachary Gould
Masters Theses
Introduction: Wearable technologies play an important contemporary role in the measurement of physical activity (PA) and promotion of human health across the lifespan, including for young people (i.e., children, adolescents, and young adults). As new objective wearable technologies continue to develop, standardized approaches to documenting validation parameters (i.e., measures of accuracy, precision, and bias) are needed to ensure confidence and comparability in step-defined PA. Purpose: To produce validity parameters for step counting wearable technologies during treadmill walking in young people 6-20 years of age Methods: 120 participants completed 5-minute treadmill bouts from13.4 to 134.1 m·min-1. Participants wore eight …
Cadence As An Indicator Of The Walk-To-Run Transition, Colleen Chase
Cadence As An Indicator Of The Walk-To-Run Transition, Colleen Chase
Masters Theses
Humans naturally select a point at which to transition from walking to running when gradually increasing locomotor speed. This point is known as the walk-to-run transition (WRT). The WRT is traditionally expressed in terms of speed and is known to occur within a close range of 2.1 m/s, which is an accepted heuristic (i.e., empirically based, rounded) threshold value. Very little research exists defining the WRT in terms of cadence (steps/min) despite the fact that spatial temporal aspects of gait underlying the WRT include this parameter. Preliminary evidence suggests that the WRT may be associated with a cadence of 140 …

Using Motivational Interviewing To Increase Walking And Functional Ability In Older Adults: A Quasi-Experimental Study, Erin Lamoureux
Using Motivational Interviewing To Increase Walking And Functional Ability In Older Adults: A Quasi-Experimental Study, Erin Lamoureux
Doctoral Dissertations
The purpose of this study was to determine if brief motivational interviewing (MI) sessions would increase daily steps and functional ability in older adults. Regular exercise in the older adult can slow the physical, psychological, and functional decline that is often associated with aging. However, only 25% of adults aged 65 and older meet the suggested physical activity recommendations of the American Heart Association and the National Institute of Health. Understanding what may contribute to the initiation and adherence of exercise within the older adult population might identify interventions that would successfully increase physical activity. This study focused specifically on …
Does Age Influence Dynamic Stability And Muscular Power Following Neuromuscular Fatigue In Women?, Ben J. Hoffmann
Does Age Influence Dynamic Stability And Muscular Power Following Neuromuscular Fatigue In Women?, Ben J. Hoffmann
Masters Theses
Older adults, especially older women, produce less muscular power than young adults, due primarily to slower maximal contractile velocity. These decrements may lead to increased fall risk in older women and can be exacerbated by fatigue. Recently, a 32 min walking task (32MWT) was shown to elicit fatigue in older women. The purpose of this study was to determine whether knee extensor (KE) maximal velocity is related to dynamic stability (margin of stability, MoS) in young and older women pre- and post-32MWT. METHODS: Nine young (Y; 24.3+1.1years, mean±SE) and 17 older (O; 71.1±1.1years) healthy women completed 2 testing sessions on …
Effect Of A Tai Chi Chuan Slow Walking Intervention On Balance And Mobility In Individuals With Multiple Sclerosis, Julianna Averill
Effect Of A Tai Chi Chuan Slow Walking Intervention On Balance And Mobility In Individuals With Multiple Sclerosis, Julianna Averill
Masters Theses 1911 - February 2014
In people with Multiple Sclerosis (MS) balance impairments may lead to increased falls and mobility loss. In quiet stance, people with MS display greater postural sway than healthy controls. Tai Chi is a Chinese martial art that has decreased the risk of falling in frail elderly individuals (Wolf et al., 1996). The purpose of this study was to determine if a three week Tai Chi intervention would improve postural stability in people with MS. Seven participants (6F/1M, age 48.5 ± 10.8 years, height 1.66 ± 0.08m, mass 68.6 ± 19.8kg) attended nine one hour training sessions to practice two types …
