Through Their Eyes: Exploring The Relationship Between College Females' Body Perceptions And Recreation Center Messaging, Sydney Leigh Ann Cindrich

Dissertations and Theses @ UNI

The study aimed to investigate the influence that recreation center promotional messaging had on college females’ body perceptions. Body perceptions among young adult females have been linked to mental health (McKay, 2013; Miner-Rubino, Twenge, & Fredrickson, 2002). Female participants 18 to 25 years of age (N = 137, Mage = 20.41) from a mid-sized, Midwestern university completed two separate body perception questionnaires. These questionnaires assessed body appreciation (functionality) and body shame (objectification). Participants were divided into three groups and shown a collage of recreation center messages that were portraying one of three conditions (a) body functionality, (b) self-objectification, or (c) …

Kinesiology Faculty Publications and Presentations

In this study, we investigated the effects of football shoes with different collar heights on ankle biomechanics and dynamic postural stability. Fifteen healthy college football players performed anterior and lateral single-leg jump landings when wearing high collar, elastic collar, or low collar football shoes. The kinematics of lower limbs and ground reaction forces were collected by simultaneously using a stereo-photogrammetric system with markers (Vicon) and a force plate (Kistler). During the anterior single-leg jump landing, a high collar shoe resulted in a significantly smaller ankle dorsiflexion range of motion (ROM), compared to both elastic (p = 0.031, dz = …

Analyzing Change-Of-Direction And The Laterally Resisted Split Squat: Incorporating A Lateral Vector Into The Single Leg Squat, Derek Maddy

Boise State University Theses and Dissertations

Improving change of direction (COD) with the use of strength training has led to mixed results. To date, the modified single leg squat (MSLS) and the bilateral squat (BS) have been successfully used to improve COD, with equal improvement. COD is primarily performed at a 45-75° frontal plane angle; however, the MSLS and BS are performed at a 90° frontal plane angle. Based on the force vector theory, it is proposed that a more mechanically similar strength training exercise, the Laterally Resisted Split Squat (LRSS), be used. The purpose of this study is to compare COD with the LRSS, MSLS, …

Effects Of Pre-Workout Caffeine Supplementation On Post-Exercise Hypotension, Shelby L. Gibbs

Electronic Theses and Dissertations

Post-exercise hypotension (PEH) is believed to play a major role in the antihypertensive health benefits of exercise. While it has been shown that resistance exercise is effective at eliciting PEH, commonly consumed sports supplements may attenuate or completely eliminate that response. Caffeine, a popular stimulant, is often consumed prior to exercise. Therefore, the purpose of this study was to investigate the effects of pre-workout caffeine supplementation on the post-exercise hypotensive response in adults with above normal blood pressure. Participants (n = 5) were recreationally resistance trained men and women who consumed placebo or caffeine (3 mg/kg bodyweight) 45-minutes prior to …

Preliminary Study: Leucine Supplementation Exacerbates Muscle Wasting Independent Of The Ubiquitin-Proteasome System, Katarina Bejarano

Graduate Theses and Dissertations

Cancer cachexia is the rapid, drastic loss of muscle mass associated with cancer and is not reversible by conventional nutritional means (Brown et al., 2018; Brown et al., 2017). It occurs in ~80% of cancer patients and is responsible for 20-40% of cancer-related deaths (Brown et al., 2018; Brown et al., 2017). This condition leaves patients with fatigue, functional impairment, reduced quality of life, and a decrease in survival rates. Cachexia occurs through an imbalance between protein degradation and protein synthesis (Brown et al., 2018), which is associated with inflammation and altered metabolic processes.

Several studies have investigated the effects …

PRESCRIBING VIGOROUS INTENSITY EXERCISE TO OLDER ADULTS

by

Taylor Rowley

The University of Wisconsin-Milwaukee, 2020

Under the Supervision of Professor Scott Strath, PhD

As the older adult segment of society grow, rates of chronic disease and poor fitness continue to climb. Physical activity (PA) and exercise are effective methods to offset incidence of disease and improve physical fitness. However, despite these known benefits, older adults exhibit low rates of PA engagement. Barriers to PA that are specific to older adults include lack of knowledge and perceived lack of time. Interventions targeting older adults and addressing these barriers by way …

The Role Of Protein Degradation In Cancer Cachexia In Female Tumor Bearing Mice, Noah Thomas

Graduate Theses and Dissertations

Background: Cancer is a leading cause of death in the world in which half of the people affected by this disease die from its effects. Cancer-cachexia is a syndrome associated with the significant loss of skeletal muscle mass and function, which cannot be fully reversed by nutritional intervention alone and in turn, impairs the host. Cancer-cachexia affects 50-80% of cancer patients and is a primary cause of death accounting for 20-40% of cancer related deaths. Efforts to reverse the effects of cancer-related cachexia have been largely unsuccessful and have primarily focused on the late stages of CC. Methods: Lewis Lung …

Bilateral Muscle Oxygenation Kinetics In Response To Repeat Sprint Cycling In Strong And Weak Individuals, John Abbott

Electronic Theses and Dissertations

Repeat sprint ability has been investigated thoroughly, however optimal training methodology to improve RSA remains elusive. Both kinetic and physiological viewpoints have been used to scrutinize aspects of RSA including, initial sprint performance (anaerobic power), maximal cardiorespiratory fitness (VO2max), lactate threshold, anaerobic capacity (mean power), muscle activation (EMG), and local muscle oxygenation kinetics. To our knowledge no study has utilized maximal strength levels as a separate factor among a homogenous group of cardiorespiratory fitness individuals (as determined by peak VO2 during RSA). The purpose of this study was to better understand the relationship between maximal strength, muscular characteristics, and cycling …

The Effects Of Group Fitness Classes On Self-Efficacy, Katherine Dalton

Graduate Theses and Dissertations

Self-efficacy is one of the largest predictors of behavior, when related to exercise studies have shown that self-efficacy can predict drop-out rates within six months of being an exercise program (Middelkamp, et. al., 2016; Sallis, et. al., 1988). College students have the biggest decline in physical activity when compared to other stages of life (Buckworth, 2001; Grubbs & Carter, 2002). University recreation centers provide group fitness classes for students to promote physical activity. Minimal research has been done to show the impact that group fitness classes has on student life. This study aimed to show the impact of group fitness …

Investigation Of Acute Response To Carbohydrate In Subsequent Resistance Training, Damon Mccune

UNLV Theses, Dissertations, Professional Papers, and Capstones

Resistance training has been shown to have several positive benefits to health including increasing muscle size and strength, reducing risk of sarcopenia with aging, and is associated with reduced risk of mortality. A cornerstone in accomplishing these goals is to progressively overload the muscle by increasing training volume to promote muscle protein synthesis following training stimulation. Total training volume has been demonstrated in the literature to be a prime determinant of muscle hypertrophy and overall training performance. Carbohydrate (CHO) manipulation has been observed as a potential ergogenic aid when training demands are high. Current research investigating nutrition related to exercise …

Respiratory And Perceptual Responses To High Intensity Interval Exercise In Obese Adults, Nicholas Andrew Ross

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose: Obese adults experience low lung volume breathing at rest and during exercise, which provokes ventilatory constraints and dyspnea on exertion. High-intensity interval exercise (HIIE) has emerged as an alternative to continuous exercise (CE); however, the effects of HIIE on lung volumes, ventilatory constraints and dyspnea on exertion have not been studied in obese adults and thus tolerability of HIIE remains unknown. Therefore, the purpose of this study was to examine the differences in respiratory and perceptual responses during HIIE versus CE in obese adults when compared with nonobese adults. Methodology: Ten healthy, nonobese (24.1 ± 6.2 yr., BMI: 23 …

Effects Of Asthma On Lung Function, Aerobic Fitness, And Physical Activity Levels In Young Adults, Trey Deal

Health, Human Performance and Recreation Undergraduate Honors Theses

Background: Asthma is one of the most commonly diagnosed conditions in the United States. Research has shown that one form of asthma, exercise-induced bronchoconstriction, is experienced by the overwhelming majority of individuals with the condition during physical activity, potentially causing fear and avoidance of physical activity in the future. Physical inactivity could have several negative health implications, including lower lung function and aerobic fitness levels. Purpose: The purpose of this study is to compare lung function, aerobic fitness, and physical activity levels between young adults with asthma to those without asthma. The hypothesis is that there will be a statistically …
