Health and Sport Science Faculty Publications

This study compared the ergogenic effects of caffeine on men who were endurance trained to those who were untrained. The study was a double-blind, placebo-controlled crossover experimental design. Ten endurance trained men (mean age 24.4 ± 2.0 yrs, weight 79.4 ± 8.5 kg, predicted VO2 max 46.3 ± 1.8 mL·kg-1·min-1) and 10 untrained men (mean age 22.8 ± 1.9 yrs, weight 88.9 ± 9.9 kg, predicted VO2 max 37.6 ± 2.7 mL·kg-1·min-1) completed two cycle ergometer trials to exhaustion at 80% of their predicted workload max 30 min after ingesting either 5 mg·kg-1 of body weight of caffeine or a …

Surfing Injuries Requiring First Aid In New Zealand, 2007-2012, Kevin Moran, Jonathon Webber

International Journal of Aquatic Research and Education

In an island nation such as New Zealand with easy access to surf beaches, surfing activities are very popular and, while generally perceived as a healthy form of outdoor recreation, they do have attendant risks. This study reports on nondrowning, surfing-related incidents that required medical first aid on beaches during five summer seasons from 2007-2012. Retrospective descriptive analysis of data from lifeguard first aid reports found that 16% (n = 1,327) of injuries were the consequence of surfing activity. More males than females were treated for surfing injuries (68% male, 31% female). Lacerations (59%) and bruising (15%) accounted for most …

Eating Pathology, Supplement Use, And Nutrition Knowledge In Collegiate Athletes, Holly Beth Lapota

UNLV Theses, Dissertations, Professional Papers, and Capstones

Eating pathology (e.g., body dissatisfaction, binge eating, purging, restrictive eating) and substance use (e.g., dietary supplements, legal and illegal drugs) proliferate university settings in the United States. Within university settings, athletes appear to be at particularly high risk for eating pathology and supplement use due to the external pressures to be attractive, the need to perform at optimal levels, and the specific characteristics of sports in which they participate. Furthermore, the degree to which athletes understand what constitutes healthy eating and exercise habits is understudied and may relate to eating pathology and supplement use. To build on existing research, the …

The Influence Of Respiratory Muscle Training On Exercise Endurance 2013, Justin Vanderbeck

Master's Theses

Exercise endurance in multiple populations has been shown to increase after bouts of respiratory muscle training (RMT) (Bailey, Romer, Kelly, Wilkerson, Dimenna & Jones, 2010; Brown, Sharpe, Graham & Johnson, 2008; Griffiths & McConnell, 2007; Kilding, Brown & McConnell, 2007; Laoutaris et al., 2012; Markov, Spengler, Stuessi, Boutellier & Knöpfli-Lenzin, 2001; Spengler & Boutellier, 2000; Stuessi, Spengler, Knöpfli-Lenzin, Markov & Boutellier, 2001; Volianitis et al., 2000). The use of resistance via respiratory muscle strength training (RMST) has been shown to produce greater increases in endurance than with no resistance, but the method of RMST that produces the greatest increases in …

An Investigation Of Preferred Versus Imposed Exercise, Personality Traits, And Motivation On An Exercise Dependent College Aged Sample 2013, Chelsea M. Norton

Master's Theses

The purpose of this study was to: (a) investigate personality traits and motivation among an exercise dependent sample by using and examining theoretically based assessment tools and (b) measure feeling states under different types of physical activity among those who were considered to be exercise dependent. Four hundred twenty-three college students (54.4% male, 45.6% female) who met the inclusion criteria completed the Exercise Dependence Scale-Revised (EDS-R; Symons Downs, Hausenblas, & Nigg, 2004), Exercise Addiction Inventory (EAI; Terry, Szabó, & Griffiths, 2004), Exercise Identity Scale (EIS; Anderson & Cychosz, 1994), Behavioral Regulations in Exercise Questionnaire-2 (BREQ-2; Markland & Tobin, 2004), and …

The Role Of Appearance In Perceptions Of Personal Trainers 2013., Patrick R. Boerner

Master's Theses

The field of personal training in the United States is believed to have begun in the late 1970‟s and the early 1980‟s (Brooks, 2004). Today, personal training is a healthy profession that, according to the United States Department of Labor and the Bureau of Labor Statistics (2012), is expected to grow 24% (60,400 jobs) between 2010 and 2020. In comparison, the Bureau of Labor Statistics (2012) predicts the average growth rate for all occupations within the U.S. to be only 14% during the same ten-year span. Rapid growth within the field of personal training has brought an increased scrutiny on …

Predicting Chest Press Strength From A 4rm Triceps Brachii Exercise In Trained Women, Krystina Nadia Moschella

UNLV Theses, Dissertations, Professional Papers, and Capstones

Determining maximal strength is important when developing a resistance exercise program for trained athletes. The most frequent strength procedure used to evaluate maximum strength is the 1RM test. However, risk of injury from a 1RM test increases for the athletes, therefore a 4RM test is used in the following study. The purpose of the study is to test whether there is a linear relationship between the bench press and the triceps rope extension exercise. A secondary purpose is the development of a prediction equation for the purpose of prescribing bench press exercise loads from triceps brachii loads using a 4RM …

Ncaa Division I Head Coaches' Experiences With Eating Disorders And Disordered Eating In Female Athletes: A Qualitative Analysis, Caitlyn Pecinovsky

College of Graduate Studies: Theses & Dissertations

In today's sport, NCAA Division I female athletes are under a constant pressure to reach an elite level of perfection in athletic performance, frequently adhering to the assumption that there is an inverse relationship between body size and performance level (Petrie & Sherman, 2007). Additionally, coaches have unrealistic expectations about weight and body image, which adds pressure on athletes to conform to certain weight or image driven standards. Perceptions that coaches hold about eating disorders and disordered eating present a set of risk factors that may increase the likelihood of female athletes developing maladaptive eating patterns (Scoffier, Maiano, & d'Arripe-Longueville, …

Too Much Puff, Not Enough Push? Surf Lifeguard Simulated Cpr Performance, Kevin Moran, Jonathon Webber

International Journal of Aquatic Research and Education

The purpose of this paper is to report on the technical competency of volunteer surf lifeguards to perform CPR on a manikin in light of their lifeguard experience, age, and gender. The CPR skills of surf lifeguards on patrol at the beginning of the 2010-11 summer season were tested on manikins by observation of CPR procedures and electronic recording of compression and ventilation skills. Almost all lifeguards (n=252) made the appropriate initial checks for responsiveness (98%). Compression skills were generally performed accurately with few technical errors (such as incomplete release). Most lifeguards (87%) over-ventilated the lungs (> 600ml) on each …

Perceptions Of Delinquency Among Male Athletes And Non-Athletes: A Qualitative Investigation, Humphrey Nartey

College of Graduate Studies: Theses & Dissertations

It is presumed that the involvement in sports helps to deter delinquency, yet athletes who seemingly have it all engage in destructive delinquent lifestyles (Savini, 2008). Many theorists contend that the "jock identity" or "sport hubris" is largely responsible, as people think they will be treated more favorably if they are athletes (Miller et al., 2006). This perception raises the question of whether athletes know and understand the constructs of delinquency. Thus the purpose of this study was to examine male athletes' and non-athletes' perceptions of the minor and major substrates of delinquency. A semi-structured interview was used to gather …

Understanding The Behavior And Attitude Of Professional Athletes In Saudi Arabia Toward Dietary Supplements, Sulaiman O. Aljaloud

Dissertations

A dietary supplement is defined as a product taken orally that contains a "dietary ingredient" (vitamins, minerals, herbs, amino acids, enzymes, etc.), and is intended to supplement one's diet. Dietary supplements include plant extracts and concentrates from foods. Supplements help provide required nutrients to fulfill nutritional levels for daily training or competitive performance, and can help remedy nutritional deficiencies. Therefore, it is important that sports professionals have a thorough knowledge of these supplement products. However, athletes need to be informed about the use and possible benefits, side effects, and risks associated with the use of dietary supplements. Four objectives guided …

Sex-Specific Effects Of Exercise Ancestry On Metabolic, Morphological And Gene Expression Phenotypes In Multiple Generations Of Mouse Offspring, Lisa M. Guth, Andrew T. Ludlow, Sarah Witkowski, Mallory R. Marshall, Laila C.J. Lima, Andrew C. Venezia, Tao Xiao, Mei Ling Ting Lee, Espen E. Spangenburg, Stephen M. Roth

Exercise and Sport Studies: Faculty Publications

New findings: • What is the central question of this study? How does parental exercise training directly and/or transgenerationally affect offspring phenotypes over two generations of mice? • What is the main finding and what is its importance? We observed preliminary evidence that parental exercise training can influence health-related phenotypes (e.g. body and fat mass, muscle gene expression) in mouse offspring. These findings indicate that parental exercise may be another environmental factor (like altered nutrition) capable of influencing offspring phenotypes in adulthood. Early life and preconception environmental stimuli can affect adult health-related phenotypes. Exercise training is an environmental stimulus affecting …

Concussion Knowledge In Amateur Motocross, Kristina Miller

College of Graduate Studies: Theses & Dissertations

The Center for Disease Control and Prevention estimated that there are 1.6-3.8 million sports related traumatic brain injuries in the United States annually which occur in both mainstream and extreme sports. Many of these concussions have been associated with collisional sports, like football, but high risk extreme sports, like motocross, also have many opportunities for collisions to occur. Unlike traditional varsity sports motocross races, especially at the amateur level, do not require more than advanced life support at a race in case of emergency situation leaving the amateur rider to recognize and decide on concussion management. Purpose of this study …

Determination Of Repetitive Jumping Intensity Relative To Measured Vo2max, Laura Igaune

Masters Theses & Specialist Projects

To regular exercise and a healthy diet, the American Heart Association (AHA) strongly recommends rope jumping, and according to previous studies, rope jumping is considered a very strenuous exercise. Therefore the purpose of this study was to determine the steady state metabolic cost of repetitive jumping on the Digi-Jump machine, and to determine if exercise on this device is more or less strenuous than similar exercise with a jump rope. We also evaluated relative intensity of this type of exercise, based on each person’s VO_2max as measured on a treadmill. Twenty – seven subjects completed two trials, one jumping …

A Study To Determine If University Athletic Teams In Desert Environments Experience Risky Diet-Related Behaviours, Susan Meacham, Christine Bergman, Marcia M. Ditmyer, Kyle Wilson, Connie Mobley

Nevada Journal of Public Health

Training and competing in desert environments may exacerbate concerns related to disordered eating, supplement use, and hydration in some student athlete populations. A survey administered equitably to both genders solicited self-reported responses from members of 18 different teams over four years from a southwestern United States university athletic program. More than 1,700 athletes responded to 42 items on the questionnaire. Teams, not individual student athletes, were the units of measure for statistical analyses. Initial analysis of results indicated that there were no overt concerns regarding dietary behaviors due to training and competing in the desert environment. Further analysis subjected the …

Individuals With Non-Specific Low Back Pain In An Active Episode Demonstrate Temporally Altered Torque Responses And Direction-Specific Enhanced Muscle Activity Following Unexpected Balance Perturbations, Stephanie L. Jones, Juvena R. Hitt, Michael J. Desarno, Sharon M. Henry

Exercise and Sport Studies: Faculty Publications

Individuals with a history of non-specific low back pain (LBP) while in a quiescent pain period demonstrate altered automatic postural responses (APRs) characterized by reduced trunk torque contributions and increased co-activation of trunk musculature. However, it is unknown whether these changes preceded or resulted from pain. To further delineate the relationship between cyclic pain recurrence and APRs, we quantified postural responses following multi-directional support surface translations, in individuals with non-specific LBP, following an active pain episode. Sixteen subjects with and 16 without LBP stood on two force plates that were translated unexpectedly in 12 directions. Net joint torques of the …

Chronic Exercise Modifies Age-Related Telomere Dynamics In A Tissue-Specific Fashion, Andrew T. Ludlow, Sarah Witkowski, Mallory R. Marshall, Jenny Wang, Laila C.J. Lima, Lisa M. Guth, Espen E. Spangenburg, Stephen M. Roth

Exercise and Sport Studies: Faculty Publications

We evaluated the impact of long-term exercise on telomere dynamics in wild-derived short telomere mice (CAST/Ei) over 1 year. We observed significant telomere shortening in liver and cardiac tissues in sedentary 1-year-old mice compared with young (8 weeks) baseline mice that were attenuated in exercised 1-year-old animals. In contrast, skeletal muscle exhibited significant telomere shortening in exercise mice compared with sedentary and young mice. Telomerase enzyme activity was increased in skeletal muscle of exercise compared with sedentary animals but was similar in cardiac and liver tissues. We observed significant age-related decreases in expression of telomere-related genes that were attenuated by …

Surf Lifeguard Perceptions And Practice Of Cardiopulmonary Resuscitation (Cpr), Kevin Moran, Jonathon Webber

International Journal of Aquatic Research and Education

While the importance of lifeguards in providing immediate and effective basic life support (BLS) in drowning has been well reported, not a lot is known about how lifeguards perceive the relative value of CPR as a lifeguard skill, their training in it, and the likelihood of resuscitation being successful. A self-complete questionnaire was completed by 252 volunteer surf lifeguards at 16 surf beaches in the Greater Auckland,NZ region. Results show that most lifeguards (65%) had received training in the 3 months before the survey, 83% were willing to perform CPR, few (9%) had used CPR in an emergency, and many …

Individuals With Non-Specific Low Back Pain Use A Trunk Stiffening Strategy To Maintain Upright Posture, Stephanie L. Jones, Sharon M. Henry, Christine C. Raasch, Juvena R. Hitt, Janice Y. Bunn

Exercise and Sport Studies: Faculty Publications

There is increasing evidence that individuals with non-specific low back pain (LBP) have altered movement coordination. However, the relationship of this neuromotor impairment to recurrent pain episodes is unknown. To assess coordination while minimizing the confounding influences of pain we characterized automatic postural responses to multi-directional support surface translations in individuals with a history of LBP who were not in an active episode of their pain. Twenty subjects with and 21 subjects without non-specific LBP stood on a platform that was translated unexpectedly in 12 directions. Net joint torques of the ankles, knees, hips, and trunk in the frontal and …

Dynamic Variability Of Isometric Action Tremor In Precision Pinching, Tim Eakin, Waneen Spirduso, Karen Francis

Kinesiology (Formerly Exercise and Sport Science)

Evolutionary development of isometric force impulse frequencies, power, and the directional concordance of changes in oscillatory tremor during performance of a two-digit force regulation task was examined. Analyses compared a patient group having tremor confounding volitional force regulation with a control group having no neuropathological diagnosis. Dependent variables for tremor varied temporally and spatially, both within individual trials and across trials, across individuals, across groups, and between digits. Particularly striking findings were magnitude increases during approaches to cue markers and shifts in the concordance phase from pinching toward rigid sway patterns as the magnitude increased. Magnitudes were significantly different among …

A History Of Low Back Pain Associates With Altered Electromyographic Activation Patterns In Response To Perturbations Of Standing Balance, Jesse V. Jacobs, Sharon M. Henry, Stephanie L. Jones, Juvena R. Hitt, Janice Y. Bunn

Exercise and Sport Studies: Faculty Publications

People with a history of low back pain (LBP) exhibit altered responses to postural perturbations, and the central neural control underlying these changes in postural responses remains unclear. To characterize more thoroughly the change in muscle activation patterns of people with LBP in response to a perturbation of standing balance, and to gain insight into the influence of early- vs. late-phase postural responses (differentiated by estimates of voluntary reaction times), this study evaluated the intermuscular patterns of electromyographic (EMG) activations from 24 people with and 21 people without a history of chronic, recurrent LBP in response to 12 directions of …
