The Relationship Between Body Image And Exercise Type, Ashley Littrell

Undergraduate Honors Theses

Exercise can have very beneficial effects on health and body satisfaction, but sometimes a negative body image gets in the way of exercising. Modern society holds certain beauty ideals in high regard, and these standards are often unattainable and unrealistic. These outside pressures to look a certain way can have a very negative effect on an individual’s body image, or the way that a person perceives his or her own appearance. There have been many studies done that have attempted to define the relationship between body image with exercise behaviors (Burger and Diony 2002, Hall and Pearson 2013). Some studies …

The Relationship Between Ratings Of Perceived Exertion And Heart Rate In Ncaa Division Iii Male Soccer Players 2017, Samuel J. Guider

Master's Theses

Every sport has specific physical demands of the human body. The amount of physiological load that an athlete endures during a bout of exercise can be described as training load (TL). Accurate calculation of training loads within athletes is important when it comes to strength and power development, as well as injury prevention and monitoring fatigue. Common methods used to calculate training loads for athletes include rating of perceived exertion (RPE) based methods, heart rate (HR) based methods, rate of oxygen consumption (VO2) methods, and blood lactate methods. Specifically with NCAA male soccer athletes, HR based methods and RPE based …

Illegitimate Bodies In Legitimate Times: Life, Liberty And The Pursuit Of Movement, Brian Culp

Faculty Articles

Drawing on Michel Foucault’s concepts of state racism and biopower, the author of the 26th Delphine Hanna Lecture presents several claims: (a) that the idea of the illegitimate outsider in Western world governments like the United States has largely been influenced by ancient Greek ideals, (b) that a host of policies and intentional actions by power brokers create derision and hierarchies between “old” and “new” immigrant groups, and (c) neoliberal ideology couched in actions that aim “to protect the state” is nothing more than a recoding of traditional racist rhetoric that expands systemic racism. The author identifies the capabilities approach, …

Influence Of Compression Socks On Unilateral Balance In Females, Alex E. Carlson

Honors Theses

The application of compression garments for various purposes has become popular in recent years. Research regarding the effectiveness of these garments has shown an increase in variables such as increased blood flow, decreased post-exercise soreness, and increased joint position awareness. However, little research is available concerning their possible use to increase joint stability. This research examined the efficacy of graduated compression stockings (GCS) to increase proprioceptive feedback from the ankle joint. It was hypothesized that continuous stimulation of sensory receptors in the ankle region by use of GCS would improve an individual’s static unilateral balance. Seventeen females (age: 20 +/- …

Prediction Of Cardiorespiratory Fitness From Maximal Anaerobic Capacity, Elizabeth Ann Tanner

UNLV Theses, Dissertations, Professional Papers, and Capstones

Incremental treadmill VO2max protocols are often considered the superior method of assessing cardiorespiratory fitness. These exercise test protocols stress aerobic energy production pathways. However, at the point of VO2max attainment anaerobic energy systems are the predominant mechanisms of adenosine triphosphate (ATP) production. Likewise, the Wingate cycle test, a commonly accepted method of anaerobic capacity assessment stresses anaerobic energy pathways. Based on the utilization of energy production pathways at the point of VO2max and maximal anaerobic capacity attainment a relationship between VO2max and Wingate exercise test protocols may exist. This potential relationship may facilitate the prediction of cardiorespiratory fitness from maximal …
