Effects Of Multivitamin Supplementation On Heart Rate Response In Aerobically Untrained College Aged Students, Greg A. Ryan, Charles P. Katica, Stacy H. Bishop, Robert L. Herron, Andy M. Bosak, Mark Sloniger

International Journal of Exercise Science: Conference Proceedings

Multivitamin use is increasingly prevalent in the US among most every population. Yet, previous research noted no performance benefits among individuals following a supplementation period. This study focused on the potential physiological benefits from a three week multivitamin supplementation period using 24 (20.9 ± 2.6yr) aerobically untrained college aged students. Subjects were divided equally into three groups (placebo = PL, multivitamin = MV, control = CL) and asked to perform separate eight minute bouts of exercise, consisting of six min of moderate (60%VO2max) intensity followed immediately by two min of high (85%VO2max) intensity exercise on a cycle ergometer. Following the …

Effect Of Treadmill Versus Elliptical Exercise On Calcaneal Stiffness Index Among College Age Females, Kelly Maloney, Sandie Walker, Stephanie M. Otto Ph.D.

International Journal of Exercise Science: Conference Proceedings

Osteoporosis is a disease that affects many older individuals, resulting in a decrease in bone density. Involvement in impact loading sports has been associated with greater stiffness index (SI) of the calcaneus when compared to non-impact sports and abstinence from sports. However, comparisons between the effectiveness of impact and non-impact exercise equipment on calcaneal SI is less clear. The purpose of this study was to examine the effect of treadmill versus elliptical exercise on calcaneal SI.

Daily Physical Activity And Bone Health Among High School Students, Stephanie M. Otto Ph.D., Don Morgan Ph.D., Richard S. Farley Ph.D., Jwa K. Kim Ph.D., Dana K. Fuller Ph.D., Jennifer L. Caputo Ph.D.

International Journal of Exercise Science: Conference Proceedings

With advancements in healthcare and public education, life expectancy is increasing and the prevalence of age related health conditions such as osteoporosis are rising. It is well known that children and adolescents who engage in healthy behaviors are more likely to carry those behaviors into adulthood. More specifically, children and adolescents who engage in weight bearing physical activity have higher bone density and are less likely to develop osteoporosis later in life. Furthermore, technology that measures daily physical activity is improving and individuals are interested in the amount of activity they and their children should participate in to remain healthy. …

Body Composition And Physical Fitness Of Students In High School Vs. Students Enrolled In High School Sports Academia Programs, Gunnhildur Hinriksdóttir, Frosti Sigurðsson, Anna S. Ólafsdóttir, Ragnar Bjarnason, Sigurbjörn Á. Arngrímsson

International Journal of Exercise Science: Conference Proceedings

In recent years more and more high schools in Iceland are offering sports academia programs. These programs are intended for teenage athletes in various sports who have the potential of becoming elite athletes. The sports academia programs make it easier for these student athletes to focus on training for their sport while attending high school, and thereby, enable them to get a good education and enhance their athletic potential. These programs also have the potential to reduce drop-out in sports because it is easier for the students to balance athletics and academics. Nevertheless, sports performance is not necessarily linked to …

Body Composition, Physical Activity And Fitness In Children With Moderate-To-Severe Intellectual Disability, Sigurbjorn A. Arngrimsson, Ingi T. Einarsson

International Journal of Exercise Science: Conference Proceedings

Introduction: The prevalence of overweight and obesity has been rising in most parts of the world over the past two decades (1, 2). This rise could pose even a greater problem for people with intellectual disability (ID) because they are more likely to be obese than people without ID (3). Furthermore, research has shown that a sedentary lifestyle is more prevalent among people with ID than otherwise healthy people in modern society (4). In the general population, the adverse effects of obesity on health begin early in life and physical inactivity and adiposity are associated with metabolic diseases and cancers …

The Physiological Stress Response To Anaerobic Exercise Is Altered Following Sodium Bicarbonate Supplementation, Dan J. Peart, Richard Kirk, Angela Hillman, Bryna Chrismas, Leigh Madden, Jason Siegler, Rebecca Vince

International Journal of Exercise Science: Conference Proceedings

Sodium bicarbonate (NaHCO3) is a nutritional aid that is proposed to enhance performance by reducing the state of exercise induced acidosis, however research is currently equivocal. Despite this, most research still focuses on its effects upon performance, and not whether the reduced acidosis impacts upon any other factors related to exercise. There is some research to suggest that such a reduction in [H+] can attenuate a number of physiological stress pathways such as stress hormones (1, 4), heat shock protein 72 (HSP72) and oxidative stress (3), suggesting a potential role in exercise recovery. However there are some limitations with this …

Ergometer And Dragon Boat, Stefano Loddo, Marco Vescovi M.D., Flavia Bruttini M.D., Ioanna Nakou M.D., Mario Segagni, Serena Benzo M.D., Monica Vescovi M.D.

International Journal of Exercise Science: Conference Proceedings

Dragon Boat is an activity that requires a participation of a large amount of muscles. The muscle groups involved are in order of involvement: the dorsal and abdominal muscles, biceps and triceps in the upper limbs and femoral quadriceps and gastrocnemius in the lower limbs. The athlete’s muscle building is based on strengthening exercises with weight lifting that involves both upper and lower limbs, with a particular attention to the heart. The paddle position, the rotation and the twisting of the body is taken into account. Racing and boat outings are integrated into the preparation. However the paddling technique exercises …

Children’S Winter Training In Kayak: A Multilateral Approach, Marco Vescovi M.D., Serena Benzo M.D., Daniele Bronzini, Flavia Bruttini M.D., Antonio Mortara, Ioanna Nakou M.D., Monica Vescovi M.D.

International Journal of Exercise Science: Conference Proceedings

Children’s approach to Kayak as a sport takes place at about the age of ten. The winter weather conditions of the Northern Italian valley do not usually permit training at the river for a long period of time. Additionally the weather increases the risk of the boat to turn over in case of imperfect control. For this reason we have elaborated a training scheme in which going out on the boat starts in April when the temperature (both of the water and the atmosphere) begins to raise.

Two Days, Two Marathons: Superman?, Marco Vescovi M.D., Serena Benzo M.D., Daniele Bronzini, Flavia Bruttini M.D., Antonio Mortara, Ioanna Nakou M.D., Monica Vescovi M.D.

International Journal of Exercise Science: Conference Proceedings

The river marathon races are characterized by a duration longer than two hours, with intermissions at predetermined distances depending on the route. In these intermissions the athletes make portages where the competitors carry their canoes in a foot race with a distance of about 150 meters, and then they resumes paddling.

The Effect Of Preparatory Arousal On Hand Grip Strength And 50 Metre Freestyle Swim Performance., Lewan Parker, Rebecca M. Sealey, Anne Swinbourne

International Journal of Exercise Science: Conference Proceedings

Preparatory arousal is a strategy in which an individual purposefully engages in an activity to get themselves emotionally “pumped up” or “charged up” to increase the body’s level of arousal [1]. Preparatory arousal is a common mental preparation strategy used among competitive athletes [2]. It is suggested that preparatory arousal can increase performance of simple tasks requiring maximal strength and muscular endurance and power [3]. However, the majority of preparatory arousal research has only examined non sport specific skills and thus the findings may not be transferable to actual sports that require more complex and dynamic movement patterns. With the …

C-Reactive Protein And The Disease Analog Model May Identify Predisposed Pre-Obese African-American Women, James W. Navalta, Scott Lyons, Sharon E. Whitlock, Demetrice D. Kirkwood, Scott W. Arnett, Mark A. Schafer

International Journal of Exercise Science: Conference Proceedings

While the obesity rate in the Unites States has been reported to have hit a plateau, the overall percentage of obese Americans remains alarmingly high (27% self-reported, 33% population estimate). While the subgroup with the highest 2010 obesity rate is Black, non-Hispanic women (41.9%), there remains a disparity in the research with regards to this population group. The implication of an elevated obese population puts a strain on health care, overall quality of life, and is associated with a number of other co-morbidities. Given this background, pilot work to evaluate a disease analog model for obesity would be useful with …

Building Kayak Excellence: From The Adolescent To The Elite Athlete., Marco Vescovi M.D., Daniele Bronzini, Flavia Bruttini M.D., Antonio Mortara, Ioanna Nakou M.D.

International Journal of Exercise Science: Conference Proceedings

Building an athlete in order to reach his maximum possible performance is a long process which starts from infancy. The history of our interdisciplinary group ( medical doctors-trainers) is equally long. It started in the 80s with the cooperation of a medical doctor and a trainer. Over the years, the group has grown involving new trainers, former athletes, athletes and young doctors who share their own specific knowledge in order to individualize and promote the maximal performance of each single athlete, trying to keep them in optimal health and prevent typical injuries caused by overload.

The Effect Of Fatigue On Shoulder Muscle Strength Ratios In Collegiate Water Polo Players, Bobby Sanders, Steven A. Hawkins, Michele Leblanc

International Journal of Exercise Science: Conference Proceedings

Introduction: A proposed mechanism of shoulder injuries is imbalances in the strength of the shoulder muscles, however, the effects of fatigue on these imbalances are unknown. The purpose of this study was to investigate the relationship of isokinetic-induced fatigue on the development of shoulder muscle imbalances using both the conventional and functional ratio.

Effect Of Ankle Taping And Bracing On Dynamic Balance And Perception Of Stability, William Gear, Jessica Bookhout, Amanda Solyntjes

International Journal of Exercise Science: Conference Proceedings

Ankle injuries are the most common injury associated with sports participation. A recent study examining NCAA injury data found that 14.9% of all injuries sustained in 15 intercollegiate sports were injuries to the ankle. Taping and bracing are commonly used measures to prevent and/or protect the ankle from injury. Patients often report a feeling of increased stability due to tape and/or brace, however previous studies examining the effect of ankle appliances on stability have produced conflicting results. The purpose of this study was to examine the effect of taping and bracing on dynamic stability, and the perception of stability with …

Effect Of Increasing Levels Of Fatigue On Knee Proprioception, William Gear

International Journal of Exercise Science: Conference Proceedings

Ligament injuries of the knee, particularly the anterior cruciate ligament (ACL), represent a significant percentage of lower extremity injuries during athletic participation. One possible factor associate with the high percentage of knee ligament injuries is a decrease in proprioception associated with fatigue. Previous research has found a decrease in proprioception following maximal fatigue of the knee musculature and following low intensity work to maximum fatigue. To date no investigation has examined if incremental increases in fatigue have an effect on proprioception. Therefore, the purpose of this study was to examine the effect of increasing levels of fatigue on active joint …

Blood Volume Unloading Reduces Cerebral Blood Flow, Taylor Drury, Darren Warburton, Aaron Phillips, Shannon Bredin

International Journal of Exercise Science: Conference Proceedings

Introduction: Cerebral autoregulation (CA) has been understood for over 50 years to maintain constant cerebral blood flow (CBF) over a wide range of arterial blood pressures (60-150 mmHg), and blood volumes. The original work, which published this relationship, however, was derived from a limited number of studies focused primarily on clinical populations. Since that time, it has been applied to healthy individuals and is a mainstay of almost all physiology textbooks. Recent evidence, however, has suggested that CBF in healthy individuals is not independent of alterations in blood pressure and volume, indicating a possible absence of cerebral autoregulation. Lower body …

Harvest Of The Ipsilateral Hamstrings Does Not Result In Tibial Internal Rotation Strength And Endurance Insufficiencies For Patients 12 To 36 Months Post-Anterior Cruciate Ligament Reconstruction, Giampietro L. Vairo

International Journal of Exercise Science: Conference Proceedings

Ipsilateral hamstrings tendons harvest as a primary autograft for anterior cruciate ligament (ACL) reconstruction has become increasingly prevalent among orthopaedic surgeons. Though, limited evidence exists detailing ensuing knee joint performance capacity. Previous authors have reported that ipsilateral semitendinosus and gracilis (STG) harvest results in significant tibial internal rotation strength deficiencies for related patients (1,2). However, prior data in regards to this measure have been reported as absolute as opposed to relative indices of strength and have not produced endurance results. Therefore, our objective was to profile relative tibial internal rotation strength and endurance responses to STG harvest in ACL reconstructed …

The Metabolic Cost Of A Commercialized Video Fitness Program, Michele Olson

International Journal of Exercise Science: Conference Proceedings

INTRODUCTION: Numerous fitness products and programs are promoted in mainstream society to the general public for the purposes of developing various aspects of physical fitness especially weight loss. However, there is often little information regarding these products and programs including the energy, or, caloric cost of the workout(s). Therefore, the purpose of this study was to determine the mean energy cost of a popular commercialized video exercise program titled, “The FIRM Express.”

No Accession-Specific Effect Of Rhizosphere Soil Communities On The Growth And Competition Of Arabidopsis Thaliana Accessions, Anna G. Aguilera, Adán Colón-Carmona, Rick Kesseli, Jeffrey S. Dukes

Biology Faculty Publication Series

Soil communities associated with specific plant species affect individual plants' growth and competitive ability. Limited evidence suggests that unique soil communities can also differentially influence growth and competition at the ecotype level. Previous work with Arabidopsis thaliana has shown that accessions produce distinct and reproducible rhizosphere bacterial communities, with significant differences in both species composition and relative abundance. We tested the hypothesis that soil communities uniquely affect the growth and reproduction of the plant accessions with which they are associated. Specifically, we examined the growth of four accessions when exposed to their own soil communities and the communities generated by …

Association Of Glpq With Serum-Resistance In Salmonella Typhimurium, Kristie Carlotta Mitchell

Master's Theses and Doctoral Dissertations

Salmonella typhimurium is a leading cause of infectious human gastroenteritis and systemic disease when it escapes into the bloodstream. The human serum complement system is central in fighting systemic bacterial infections. S. typhimurium exhibits resistance to killing by complement (serum-resistance), a trait conferred by several known virulence genes. This study investigates a potential chromosomal complement-resistance gene in S. typhimurium tagged by TnphoA insertional transposon mutagenesis. S. typhimurium strain EM876 has a chromosomal TnphoA insertion and reduced serum-resistance. Inverse PCR and subsequent DNA sequence analysis reveal the insertion to be in the gene glpQ. glpQ codes for a …

Traversing Swanton Road, 6th Ed., James A. West

Academic, Government & Associated Organizational Research Resources

Situated at the northwest end of Santa Cruz County and occupying circa 30 square miles of sharply contrasted terrain, the Scott Creek Watershed concentrates within its geomorphological boundaries, at least 10-12% of California's flora, both native and introduced. Paradoxically, the use/abuse that the watershed has sustained over the past 140+ years, has not necessarily diminished the biodiversity and perhaps parallels the naturally disruptive but biologically energizing processes (fire, flooding, landslides and erosion), which have also been historically documented for the area for +60 years. This is an early edition of an extensive document by James A. West. Please visit the …

Biochemical And Pharmacological Characterization Of Cytochrome B5 Reductase As A Potential Novel Therapeutic Target In Candida Albicans, Mary Jolene Patricia Holloway

USF Tampa Graduate Theses and Dissertations

The opportunistic fungus Candida albicans is a commensal member of the human microflora and is the most common causative agent of fungal-related disease with particular significance in immunocompromised individuals. Emerging drug resistance is a major problem in Candida, contributed by enzymes involved in the detoxification of xenobiotics and pharmacological agents. One such enzyme, cytochrome b5 reductase (cb5r), has a high pharmacological significance owing to its role in fatty acid elongation, ergosterol (or cholesterol in mammals) biosynthesis, and cytochrome P450-mediated detoxification of xenobiotics.

We have compared the kinetic, biochemical, and pharmacological characteristics of C. albicans cb5r isoforms, Cbr1 and Mcr1, as …

Programmers And Forensic Analyses: Accusers Under The Confrontation Clause, Karen Neville

Duke Law & Technology Review

Recent Supreme Court cases involving the Confrontation Clause have strengthened defendants’ right to face their accusers. Bullcoming v. New Mexico explored the question of whether the testimony of the technician who performs a forensic analysis may be substituted by that of another analyst, and the Court held that producing a surrogate witness who was not sufficiently involved in the analysis violates the confrontation right.

The presumption of infallible technology is fading, and courts may soon realize programmers have greater influence over the ultimate outcome of forensic tests than do the technicians who rely on such analytical tools. The confrontation right, …

Mountains Of Injustice : Social And Environmental Justice In Appalachia, Michele Morrone, Geoffrey L. Buckley

Ohio University Press Open Access Books

Research in environmental justice reveals that low-income and minority neighborhoods in our nation’s cities are often the preferred sites for landfills, power plants, and polluting factories. Those who live in these sacrifice zones are forced to shoulder the burden of harmful environmental effects so that others can prosper. Mountains of Injustice broadens the discussion from the city to the country by focusing on the legacy of disproportionate environmental health impacts on communities in the Appalachian region, where the costs of cheap energy and cheap goods are actually quite high.

Through compelling stories and interviews with people who are fighting for …
