The Relationship Health And Attractiveness Self-Ratings With Body Satisfaction And Health Behavior, Brianna Henson, Erica Knowles, Mark D. Faries Feb 2016

The Relationship Health And Attractiveness Self-Ratings With Body Satisfaction And Health Behavior, Brianna Henson, Erica Knowles, Mark D. Faries

International Journal of Exercise Science: Conference Proceedings

‘Trigger Theory’ suggests that for a discrepancy to act as a trigger, the discrepancy must be interpreted as a ‘threat’ to an important self-concept or self-view. Triggering events have been cited as important sparks for weight loss and control behaviors in women, but only certain discrepancies result in a triggering event. The purpose for this study was to determine if there was a relationship between self-rated attractiveness and health with body mass index (BMI) self-esteem, weight satisfaction, dietary intake, and physical activity (PA). A relationship would indicate a role of both attractiveness and health self-views in self-concept and self-esteem, thus …

The Effects Of Short-Term Detraining And Subsequent Retraining On Body Composition And Muscle Performance In Males Consuming A Whey Protein Or Carbohydrate Supplement, Paul S. Hwang, Thomas L. Andre, Sarah K. Mckinley-Barnard, Joshua J. Gann, Flor E. Morales, Grant M. Tinsley, Darryn Willoughby Phd

International Journal of Exercise Science: Conference Proceedings

An acute bout of resistance exercise (RE) can up-regulate processes that stimulate muscle protein synthesis (MPS). Additionally, nutritional strategies involving carbohydrate (CHO) and whey protein (WP) supplementation can augment MPS. However, resistance training (RT) induced muscle anabolism during the early phases of training can attenuate over time. The use of a short-term cessation of training (detraining; DT) can potentially restore the attenuated muscular anabolic adaptive responses. Therefore, the purpose of this study was to explore the effects of a successive cycle of detraining and retraining (ReT) in humans on body composition and muscle performance. Resistance-trained males (age 20.95 ± 1.23 …

Comparison Of Calorie Counting Vs. Self Evaluation Methodology For Weight Loss, Sarah C. Hachar, Marisa K. Mccormack, Brittany Crim Feb 2016

Comparison Of Calorie Counting Vs. Self Evaluation Methodology For Weight Loss, Sarah C. Hachar, Marisa K. Mccormack, Brittany Crim

International Journal of Exercise Science: Conference Proceedings

INTRODUCTION: Obesity is a major health concern in the United States and one way to control it is through proper nutrition techniques (BRFSS, 2007, 2009). One technique, calorie counting, is used to control energy intake. Mindful eating, another technique, requires individuals to understand and interpret internal cues that control hunger (Timmerman, 2012). Smartphone applications have been created in order to facilitate these two techniques. Although both techniques have been proven efficacious in specific settings, the two techniques when supported by digital applications have never been compared. The purpose of this study was to analyze the effectiveness of digital support in …

Impact Of Anti-Resorptive Treatment On Recovery Of Bone After Disuse, Michael J. Junior, Corinne Metzger, Scott E. Lenfest, Ramon Boudreaux, Harry A. Hogan, Susan Bloomfield

International Journal of Exercise Science: Conference Proceedings

Bisphosphonates (BP), drugs that inhibit bone resorption, are used to minimize bone loss in long-duration spaceflight, extended bed rest, and acute spinal cord injury; however, the long term impact of BP use on recovery of bone after disuse is not well understood. This experiment tests the hypothesis that the BP zoledronic acid (ZOL) administered 7 days before hindlimb unloading (HU) will protect against loss of bone mass during 28 days of HU by suppressing bone resorption activity while also diminishing the ability of cancellous bone formation rate (BFR) to recover following HU. Male Sprague Dawley rats (6 mo) were assigned …

Destroying God’S Temple? Physical Inactivity, Poor Diet, Obesity, And Other “Sin” Behaviors, Megan E. Mcclendon, Mark Faries, Eric Jones Feb 2016

Destroying God’S Temple? Physical Inactivity, Poor Diet, Obesity, And Other “Sin” Behaviors, Megan E. Mcclendon, Mark Faries, Eric Jones

International Journal of Exercise Science: Conference Proceedings

Individual differences in health behavior across religious and spiritual individuals might be attributed to the general belief that the body is God’s temple, and should be treated with care and respect. Also, it is possible that some behaviors are thought to destroy the body (God’s temple), while inactivity, poor diet, and obesity might not be viewed in this way. Thus, our first aim was to assess current beliefs and attitudes regarding the role of physical inactivity, poor diet, and obesity in the destruction of the body, God’s temple. Subsequently, our second aim was to determine if these beliefs and attitudes …
