Fueling Performance: Determining The Efficacy Of Low-Carbohydrate Diet Models For Athletic Populations, Chelsea Jackle

Honors Theses

Advocates of low-carbohydrate (LC) diets assert that these diets help lessen dependence on sugar while aiding in the metabolism of fat tissue. Additionally, it is believed that lipolysis helps dieters feel more energetic, lose weight, and improve physical performance. For these reasons, many athletes and active people are drawn to diets such as the Atkins Diet, the South Beach Diet, the Paleo Diet, and the Zone Diet. According to current evidence, excessive weight loss, ketosis, reduced glycogen availability, dehydration, and increased stress hormone levels make LC diets that severely limit carbohydrates disadvantageous for athletes. Although LC diets are widely followed, …

The Effects Of Mouth Guards And Clenching On Strength And Power Measures Of A Countermovement Vertical Jump: A Pilot Study, Hannah M. Hudson

Honors Theses

Strength and power gains from either mouth guards or clenching have been reported in highly trained athletes from a number of studies utilizing different testing measures. However, there have not been statistically significant effects in a recreationally trained population; and there has not been a research design to combine multiple mouthpiece conditions (mouthpiece designed for performance, a traditional mouth guard, and no mouthpiece condition) with a clench and no clench sub-condition. Therefore, the purpose of this study was to evaluate potential ergogenic effects of mouth guards and clenching on strength and power measures of a countermovement vertical jump. Three recreationally …

Investigating The Effects Of Alternative Footwear On Balance, David S. May

Honors Theses

Falls are one of the leading causes of injuries and unintentional deaths in the United States, with 27,800 fatalities attributed to falls in 2012 (National Safety Council, 2014). With two thirds of our body mass located two thirds of our body height above the ground, humans require constant work from balance control systems to prevent these falls (Winter, 1995). Because shoes can alter somatosensory input from the mechanoreceptors on the bottom of the foot and affect these balance control systems (Menant et al, 2008), they must be taken into account when looking into the causes of falls. Traditional footwear designs …

The Acute Effect Of A Mandibular Repositioning Appliance On Force Production During An Isometric Clean Pull In Recreationally Trained Males, Daniel L. Hartman

Honors Theses

The use of a performance mouthpiece may cause notable performance changes in an isometric mid-thigh clean pull (iMTCP) due to altered muscular force production. The purpose of this study was to examine the effects of wearing various mouthpieces coupled with a clenching of the jaw on iMTCP force production. Three recreationally trained college-aged males (Age: 26.67 ± 2.89) volunteered to participate in three testing sessions separated by one week each. In the three sessions, the subject performed repetitions of an iMTCP under the following conditions: performance mouthpiece with jaw clenched (PMP-JC), performance mouthpiece with no clench (PMP-NC), traditional mouthpiece with …

Self Myofascial Release: Effects On Hamstring Range Of Motion And Torque, Dillion F. Evans

Honors Theses

Research has indicated that static stretching may reduce force production capabilities. This has led many practitioners to exchange static stretching for alternative methods of increasing range of motion (ROM) in warm-ups. Despite having little research to support its use, self myofascial release—foam rolling—has been suggested as a viable alternative (Macdonald et al, 2013). The objective of this study was to determine how self myofascial release (SMR) of the hamstring muscle group affects ROM and torque production capabilities of the hamstring muscle group. Ten subjects (age 26.5 6.5 years, mass 74.412.1 kg, height 1738 cm) were recruited. A within subjects randomized, …

Influence Of Whole-Body Vibration On Delayed Onset Muscle Soreness, Cecilia Drennen

Honors Theses

Exercise induced muscle damage (EIMD) results in delayed onset muscle soreness (DOMS). Whole body vibration (WBV) may be a method that can be implemented to allow a subject suffering from DOMS to recover more quickly. The purpose of this study was to determine if WBV aids in managing symptoms of EIMD over a recovery period of 72 hours and to determine the effects of WBV on jumping performance following exercise-induced muscle damage. Measurements of performance like vertical jump height, peak-Z force, and pain pressure threshold were recorded. Twenty-seven recreationally trained females participated, and were damaged by performance of the eccentric …

The Acute Influence Of Occupational Footwear On Balance, Caroline Borland

Honors Theses

There is a great number of potential risks for falls and injuries because of problems in the workplace. In 2010, there were almost 3.1 million nonfatal and 646 fatal illnesses and injuries disclosed in the workplace (BLS, 2010). Fatal and nonfatal occupational injuries have decreased in the recent years but there is still much room to improve. Inappropriate footwear has been attributed to 45% of all falls (Menant et al. 2008). Past studies have shown that industrial footwear can have a detrimental effect on balance (Menant et al. 2008, Chander, Garner & Wade 2013). Occupational footwear have not been designed …

The Effects Of Exercise-Induced Muscle Damage On Aerobic Capacity Tested Through Repeated Vo2max Tests, Luke Burnett

Honors Theses

High-intensity resistance training alongside aerobic training has been seen to improve aerobic performance due to the gains strength that accompany said resistance training. However, it has been documented that the exercise-induced muscle damage (EIMD) that results from the resistance training can impair aerobic performance in the days following. Therefore, the purpose of this study was to assess the time-course of recovery from EIMD for up to seven days following muscle-damaging protocol. Eight recreationally trained participants (age 21.88 ± 0.99 yr., mass 70.02 ± 11.14 kg, height 171.61 ± 8.99 cm) volunteered to participate in five testing sessions over the course …

Obm Thesis Project: Composing An Undergraduate Thesis Manual, William Strong

Honors Theses

The Behavioral Research Supervisory System (BRSS) is a class designed to assist undergraduate and master students in completing a thesis project in a timely manner. Prior to beginning this project, undergraduate students were not utilizing the thesis manual for the class effectively and master students did not have an effective tool to grade the quality of their undergraduate thesis students’ work. Therefore, the ultimate goal of this thesis project is to create a better manual for undergraduate students to reference while working on their thesis projects and to provide a systematic grading system for their graduate student supervisors. A pre-manual …

Racial Differences In Self-Efficacy Expectations For Exercise, Selena P. Smith

Honors Theses

This project examined the link between race and self-efficacy. Self-efficacy pertains to an individual’s confidence in ability to complete or engage in a particular task or activity (Bandura, 1986). Prior research shows that self-efficacy has a great influence on exercise initiation and adherence (Bandura, 1986; Dishman, 1982; Rodgers and Sullivan, 2001). Research also supports that Caucasians are more likely to participate in exercise than African Americans (Centers for Disease Control and Prevention, 2000).

Participants included 51 females, 31 Caucasians and 20 African Americans, between the ages of 18 and 50 years old. The women were recruited from local fitness gyms, …
