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 …

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 …
