Stationary Exercise Classification Using Imus And Deep Learning, Andrew M. Heroy, Zackary Gill, Samantha Sprague, David Stroud, John Santerre

SMU Data Science Review

In the current market, successful fitness tracking devices utilize heart rate and GPS to determine performance. These devices are useful, but don't extensively classify stationary exercise. This paper proposes a modern approach for tuning and investigating optimal neural network types on stationary exercises using Inertial Measurement Units (IMUs). Using three IMUs located on the ankle, waist, and wrist, data is collected to map the body as it moves during the stationary physical activity. A novel five-stage deep learning tuning system was written and deployed to classify user movement as one of three classes: air squats, jumping jacks, and kettlebell swings. …

Relationships Between Injury-Related Fear, Balance Self-Efficacy, And Dynamic Balance Performance In Those With Chronic Ankle Instability, Ashley M. B. Suttmiller, Kelly Johnson, Ryan S. Mccann

College of Health Sciences Posters

Interactions between sensory-perceptual and motor-behavioral impairments in individuals with chronic ankle instability (CAI) are important for successful assessment and treatment of CAI. One of the most consistently reported motor-behavioral impairments is poor reach performance in a dynamic balance task. Injury-related fear is recognized as an important sensory-perceptual impairment, and those with injury-related fears may engage in protective movement strategies found to be associated with reach deficits. Injury-related fear may also impact one’s perception of ability, or self-efficacy, which has demonstrated positive associations with balance performance in other populations, but these relationships have yet to be investigated in the CAI population. …

A Comparison Of High-Intensity Interval Running And Tabata On Post-Exercise Metabolism: A Pilot Analysis, Lauren Pate

Undergraduate Research Conference

Introduction

• It is well established that energy expenditure following exercise (EPOC) remains elevated above resting values for a period of time (3).

• The magnitude and duration of this elevation may be primarily dependent on exercise intensity, with exercise duration and expenditure having a smaller influence (3, 6).

• Short durations (≤ 30 minutes) of high-intensity interval exercise (HIIE) is becoming a popular alternative for individuals who have limited time to exercise (5).

• When compared to rest, short-duration HIIE has been reported to elicit similar elevations in EPOC when compared to longer bouts of moderate-intensity continuous exercise (MICE) …

Use Of A Novel Whole-Body Imaging Approach To Predict Resting Metabolic Rates In Athletes, Nicole Vencil

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Prediction of energy expenditure allows for calculation of appropriate energy requirements, which is especially important for athletes. Resting metabolic rate (RMR) is the greatest contributor to total daily energy expenditure (TDEE) and is typically measured via indirect calorimetry. Indirect calorimetry is not always available, which results in the need for predictive equations. Most predictive equations have been developed with participants resembling the general population and have not been found to be appropriate for athletes, as they may incorrectly predict RMR due to the unique differences of body composition between athletes and the general population. The purpose of the present study …

Integrating Survivors Of Stroke Into Cardiac Rehabilitation, Elizabeth Wherley Regan

Theses and Dissertations

Stroke is the leading cause of disability in the United States (U.S.). Impairments after stroke typically result in reduced physical activity which increases the risk for stroke recurrence and the development or worsening of comorbid health conditions. Physical activity and exercise behaviors can reduce cardiovascular risk factors and improve endurance for survivors of stroke. Despite these known significant benefits, survivors of stroke face barriers to participating in regular physical activity due to limited self-efficacy, safety concerns, environmental restrictions and lack of accessible community programs.

Cardiac Rehabilitation (CR) is a structured exercise and behavior modification program for people with cardiovascular disease …

Piloting A Smartphone-Based Sedentary Behavior Reduction Intervention For Adults With Overweight Or Obesity: Take A Stand 4 Health, Chelsea Larsen

Theses and Dissertations

INTRODUCTION: Previous studies have shown a relationship between sedentary behavior as an independent and novel risk factor for high blood pressure. However, most of the evidence comes from cross-sectional and experimental studies, with only a few studies examining whether blood pressure is improved in individuals participating in a behavioral intervention. None of these studies utilized mHealth approaches, which hold potential for behavioral interventions, and none have focused on individuals with hypertension as a part of their target population. Therefore, the purpose of the dissertation was to 1) Examine the efficacy of a smartphone-mediated multi-component sedentary behavior reduction intervention for individuals …
