An Examination Of The Influence Of Social Physique Anxiety On Effort And Exercise Participation In College Students, Trellony M. Irwin

Honors Theses

The purpose of this study was to investigate whether an individual’s perception of others influenced exercise participation and effort in women and men participants involved in exercise classes in a campus recreation facility. The study consists of a survey that utilizes the Social Physique Anxiety Scale, the Ratings of Perceived Exertion (RPE) Scale, and demographic information. Results revealed that participants’ social physique anxiety accounted for roughly 30% of the variance in self-reported physical activity. However, when it came to participant effort during the group exercise classes, there was only roughly 2% variance between social physique anxiety and RPE. Further, the …

The Acute Effects Of Resistance Exercise With Blood Flow Restriction Versus Traditional Resistance Exercise On Arterial Compliance And Energy Expenditure In Recreationally Active Males And Females, Danny D. Dominguez

Theses and Dissertations

PURPOSE: The aim of this study was to investigate the acute effects of various intensities of volume matched resistance exercise with blood flow restriction (BFR) and traditional resistance exercise on hemodynamic variables, arterial compliance, oxygen consumption (VO2), carbon dioxide production (VCO2), respiratory exchange ratio (RER), and energy expenditure (EE) during exercise and after exercise.

RESULTS: Significant condition main effects (p < 0.05) were found for RPE, HR, crPWV, fdPWV, LAE, SAE, TVI, RER during and postexercise. BFR25 cause greater increases in RPE and HR. BFR50 caused marked increases in SAE, crPWV, and fdPWV.

CONCLUSION: All BFR and traditional exercise conditions found no significant differences in EE, VCO2, and VO2. The lack of differences is likely due to time of protocol. Further protocols should implement greater time of exercise, as BFR had increased hemodynamic …

Effects Of Direction Time Constraints And Walking Speed On Turn Strategies And Gait Adaptations In Healthy Older And Young Adults, Dennis Torre

Seton Hall University Dissertations and Theses (ETDs)

Hip fractures can be life-threatening, debilitating, and costly. The odds for hip fracture increases from impact of sideways falls. While turning has been strongly associated with hip fracture & sideways falls, the distinction between the risks for walking-turns as opposed to low-velocity in-place turning is not clear. The present study sought to fill a gap as previous research had not compared walking-turn performance in young & healthy older adults at low-fall risk within the same study and response-conditions of speed interacting with direction-cue time constraints. Spatial-temporal variables representative of AP braking/propulsion (i.e. stride-length & speed) & ML stability (left/right H-H …

Clinical Predictors Of Movement Patterns In Patients With Chronic Ankle Instability, Seong Jun Son

Theses and Dissertations

BACKGROUND: Chronic ankle instability (CAI) patients have varying levels of mechanical and sensorimotor impairments that may lead to disparate functional movement patterns. Current literature on landing biomechanics in a CAI population, however, considers all patients as a homogeneous group. In our prior work, we identified 6 subgroups of movement patterns using lower extremity kinematics during a landing/cutting task and that showed promise in furthering understanding of movement patterns in a laboratory-based environment. To increase the utility of this methodology in clinical settings, there is a need to find easily administered clinical tests that can help identify multiple subgroups of movement …

Ground Reaction Forces For Irish Dance Landings In Hard And Soft Shoes, Sarah Elizabeth Klopp

Theses and Dissertations

Introduction: Irish dance has evolved to become more athletically demanding, thus making the art form very hard on dancers' bodies. Irish dancers must land from difficult moves without letting their knees bend or heels touch the ground, causing large amounts of force to be absorbed by the body. Past studies have found dancers landing with a range of 4.5–6 times body weight, potentially causing high amounts of overuse injury. The majority of injuries incurred by Irish dancers are due to overuse (79.6%). The landings that occur in Irish dance have been minimally evaluated in current literature. Obtaining values of vertical …

Response Inhibition To High Calorie Food Cues Among Adolescents Following Active And Sedentary Video Game Play Using A Go/No-Go Task: A Randomized Crossover Study, Joshua L. Smith

Theses and Dissertations

Sedentary behaviors, such as leisure time computer use and sedentary video games, are significant barriers to regular physical activity and contribute to high rates of overweight and obesity among adolescents. Sedentary screen time can adversely affect food intake and food selection. Active video games may be a promising way of increasing daily physical activity levels among adolescents. Active video games may help modulate response inhibition and food intake. PURPOSE: Compare the effects of an acute bout of active and sedentary video gaming on N2 amplitudes (while viewing high calorie and low calorie images), Stroop Color Word Test (Stroop test) performance …

Biomechanics (Chapter 9), Nicholas Stergiou, K.-C. Siu, Sara Myers, Ben Senderling

Journal Articles

Biomechanics is a discipline. A discipline deals with understanding, predicting, and explaining phenomena within a content domain, and biomechanics is the study of the human body in motion. Kinesiology, the parent discipline of biomechanics, is a science that investigates movement. Biomechanical research in human development focuses on evaluating essential movement patterns across the human life span. Biomechanical analysis is specifically important in quantifying the developmental motor skills and movement patterns such as walking, kicking, jumping, throwing, and catching. Biomechanical research also involves studying the movement patterns of injured and disabled people. Forensic biomechanists are invited to analyze evidence, clarify some …

Comparison Of Self-Esteem, Body Image, And Motives Of Physical Activity In College Students In Group And Solo Exercise, Isabella Mary Axelsson 5075558, Jody Langdon

Honors College Theses

Previous research has shown significant differences in the intensity of exercise performance and perceived body image between individuals with and without an exercise partner (Plante et al., 2010). Little research has been found which has compared the psychological factors between those who exercise with a group class and those who exercise alone. The purpose of this research study was to compare self-esteem, body image, and physical activity motives between individuals who engage in group exercise and those who exercise alone. It was expected that self-esteem, motivation and body esteem would be significantly higher in those that participate in group exercise …

The Effects Of Overfeeding On Body Composition: The Role Of Macronutrient Composition - A Narrative Review, Alex Leaf, Jose Antonio

International Journal of Exercise Science

International Journal of Exercise Science 10(8): 1275-1296, 2017. Compared to investigations on hypocaloric diets, the effects of chronic overfeeding have been less studied. It has been posited that consuming calories in excess of daily caloric requirements will result in a gain in body weight and in particular fat mass regardless of which macronutrient(s) are consumed. However, recent evidence suggests that there is a quantitative difference in protein versus carbohydrate and/or fat overfeeding as it relates to body composition. Protein overfeeding or the consumption of a high protein diet may not result in a gain in body weight or fat mass …
