Agonist And Stabilizer Muscle Activity During A Push Up On Unstable Surfaces, Anthony J. Dyrek 2011 University of Nevada, Las Vegas

Agonist And Stabilizer Muscle Activity During A Push Up On Unstable Surfaces, Anthony J. Dyrek

UNLV Theses, Dissertations, Professional Papers, and Capstones

A recent trend among fitness professionals is to have clients perform resistance exercises on unstable equipment. Anecdotally, this is done with the intent that stabilizing and agonist muscles are more active while doing certain exercises on unstable surfaces. However, there are limited data as to whether or not this is the case and no studies have investigated muscle activity while doing the same exercise on surfaces that offer different levels of stability. Therefore, the purpose of this study is to measure electromyography (EMG) during push up exercise performed on unstable surfaces as well as on the ground. Surface EMG was ...

Kinematic And Electromyographic Description Of Baseball And Softball Catching, Hillary Ann Plummer 2011 University of Arkansas, Fayetteville

Kinematic And Electromyographic Description Of Baseball And Softball Catching, Hillary Ann Plummer

Theses and Dissertations

The catcher is actively involved, defensively, in every pitch that is thrown during the duration of a baseball or softball game. Because catchers play such an active role, the outcome of the game can be decided on their ability to keep base runners from stealing and advancing into scoring position. The ability to throw out a stealing runner is a necessary skill that catchers must possess in order to be successful at their position. To keep a base runner from stealing catchers have the option of throwing down to second base from either their stance or their knees. Despite the ...

The Effects Of Sodium Bicarbonate Supplementation On Lower-Body Hypertrophy-Type Resistance Exercise, Benjamin Mclean Carr

Dissertations

A number of studies have demonstrated the ergogenic effects of induced-alkalosis on high-intensity intermittent exercise performance. Purpose: The aim of the present study was to examine the effects of sodium bicarbonate (NaHCO3) administration on a high-volume hypertrophy-type resistance exercise regimen for the lower body. Methods: In a double-blind counterbalanced manner, 12 resistance-trained male participants (mean ± SD; age = 20.3 ± 2 yr, mass = 88.3 ± 13.2 kg, height = 1.80 ± 0.07 m), with a minimum of two years of training experience, ingested either 0.3 g˙kg-1 of NaHCO3 or calcium carbonate (CaCO3) Placebo, divided ...


Do Thigh Circumference And Mass Changes Associated With Obesity Alter Walking Biomechanics?, Carolyn Grace Westlake 2011 Carolyn G Westlake

Do Thigh Circumference And Mass Changes Associated With Obesity Alter Walking Biomechanics?, Carolyn Grace Westlake

Masters Theses

Differences in gait biomechanics have been observed between obese and healthy weight adults. It is possible that body segment parameters, particularly the thigh, contribute to the differences in knee biomechanics observed during gait between obese and healthy weight adults. The purpose of this study was to determine if increases in thigh circumference and/or mass associated with obesity alter walking biomechanics in healthy weight males and females. Thigh mass and circumference were increased proportional to a 10 unit increase in body mass index. Frontal and sagittal plane knee angles and moments, and temporospatial variables were recorded. For all dependent variables ...


Comparative Forelimb Muscle Function In Turtles: Tests Of Environmental Variation And Neuromotor Conservation, Angela Rivera 2011 Clemson University

Comparative Forelimb Muscle Function In Turtles: Tests Of Environmental Variation And Neuromotor Conservation, Angela Rivera

All Dissertations

Novel locomotor functions in animals may evolve through changes in morphology, muscle activity, or a combination of both. The idea that new functions or behaviors can arise solely through changes in structure, without concurrent changes in the patterns of muscle activity that control movement of those structures, has been formalized as the `neuromotor conservation hypothesis'. In vertebrate locomotor systems, evidence for neuromotor conservation is found across transitions in terrestrial species and into fliers, but transitions in aquatic species have received little comparable study to determine if changes in morphology and muscle function were coordinated through the evolution of new locomotor ...

Lower Back And Lower Limb Injury In Ballet Dancers: Incidence And Implications, Jennifer Battisti 2011 The College at Brockport

Lower Back And Lower Limb Injury In Ballet Dancers: Incidence And Implications, Jennifer Battisti

Senior Honors Theses

While ballet looks graceful and soft, there is a real threat of injury to the ballet dancer. This senior honors thesis looks at common injuries suffered by the dancers, their cause, and ways to avoid them. The first danger explained is over-exerting children. Children have growing bodies, with underdeveloped bones and muscles. Because of this, they should not be expected to perform certain movements that adult ballet dancers are capable of. Often child dancers will attempt unmodified techniques that are unsafe for people at their developmental level.

The thesis continues to explore injuries commonly shared among ballet dancers of all ...


Post-Exercise Hypotension In Brief Exercise, Jeremiah G. Bush 2011 Western Kentucky University

Post-Exercise Hypotension In Brief Exercise, Jeremiah G. Bush

Masters Theses & Specialist Projects

The purpose of this investigation was to examine whether a single 10 minute bout of exercise, performed at multiple intervals throughout the day to equal 30 minutes, can effectively elicit post-exercise hypotension (PEH). Secondly, it is important to explore whether a light (40% VO2R) or moderate (70% VO2R) intensity is required to elicit PEH within 10 minutes. Subjects (N=11) completed a VO2max test utilizing the Bruce Treadmill protocol. Each subject returned within 3 – 5 days to complete two separate exercising trials. A counter balanced system was employed so that each subject did not perform the same intensity rotation (Counter ...


The Effects Of A Lumbopelvic Hip Complex Conditioning Program On Dynamic Knee Valgus In Female Tennis Players, Katelyn Marie Roling 2011 University of Arkansas, Fayetteville

The Effects Of A Lumbopelvic Hip Complex Conditioning Program On Dynamic Knee Valgus In Female Tennis Players, Katelyn Marie Roling

Theses and Dissertations

Female athletes have a four-to-six times greater risk of sustaining a lower extremity injury than their male counterparts (Hewett, 2000). One explanation for the discrepancy in injury rates is increased dynamic knee valgus angles caused by neuromuscular imbalances of the lumbopelvic hip complex (LPHC). The purpose of this study was to determine if implementing a LPHC conditioning program improved neuromuscular deficiencies. Seven female collegiate tennis players competitive at the NCAA Division I level volunteered for the study (19.7 + .95 years, 167.3 + 7.4 cm, and 60.72 kg + 6.71 kg). The subjects participated in a 16 week ...


Walk-Run Transition Speed And The Relevance Of Loading, Muscular Fatigue, And Human Kinematics: A Comparison Of Human Gait Patterns, Callie Elizabeth Gunderson 2011 Boise State University

Walk-Run Transition Speed And The Relevance Of Loading, Muscular Fatigue, And Human Kinematics: A Comparison Of Human Gait Patterns, Callie Elizabeth Gunderson

Boise State University Theses and Dissertations

INTRODUCTION: The walk-to-run transition (WRT) typically occurs at a preferred transition speed (PTS) of 1.9-2.1ms-1. Previous research has focused on potential triggers for this transition such as leg length, muscular fatigue, loading rates (LR), and vertical ground reaction forces (VGRFs). Rather than focus on mechanisms responsible for the transition, the purpose of the current study was to determine if basic anthropometrics or gait characteristics are predictive of the WRT. METHODS: Thirty participants were recruited for the current study (n = 13 male, 17 female; n = 11 normal weight, n = 10 overweight, n = 9 obese; age M = 26.3 ...


Effects Of Xs® Energy Drink On Aerobic Exercise Capacity Of Athletes, Kevin M. Sheehan, Lynn K. Hartzler 2011 Wright State University

Effects Of Xs® Energy Drink On Aerobic Exercise Capacity Of Athletes, Kevin M. Sheehan, Lynn K. Hartzler

International Journal of Exercise Science

A small increase in performance is often the difference between winning and losing for athletes, and energy supplements are marketed to give them a competitive edge. One such supplement is XSAlt 0174 Energy Drink which contains B vitamins, caffeine, taurine, and an herbal adaptogen blend. XSAlt 0174 Energy Drink is primarily designed and marketed as an alertness stimulus; however, it is also marketed to athletes as a performance enhancing supplement. We hypothesized that the consumption of XSAlt 0174 Energy Drink before exercise would increase aerobic capacity (an increase in Vo2max) and time to fatigue, and would decrease time for recovery ...

Effects Of A Caffeine-Containing Transdermal Energy Patch On Aerobic And Anaerobic Exercise Performance, Kenneth R. Dragoo, W. Matthew Silvers, Kelly E. Johnson, Eliseo A. Gonzalez

International Journal of Exercise Science

The use of caffeine-containing (74-mg) energy patches (EnP) offers a novel mode of caffeine delivery that may alleviate stomach discomfort associated with oral caffeine use. The purpose of this study was to use four separate tests to evaluate the effects of EnP use on aerobic and anaerobic exercise performance. Three separate moderately active college-aged sample populations performed either 1) cycle time-to-exhaustion, 2) Wingate (WIN), or 3) repeated sprints and one repetition maximum bench press using EnP and placebo patches (PlP). No statistical differences were found between EnP and PlP for all dependent variables (p > 0.05) except for WIN peak ...

Knee Osteoarthritis And The Efficacy Of Kinesthesia, Balance & Agility Exercise Training: A Pilot Study, Matthew W. Rogers, Nauris Tamulevicius, Marius F. Coetsee, Beth F. Curry, Stuart J. Semple

International Journal of Exercise Science

Kinesthesia, balance and agility (KBA) neuromuscular exercises are commonly used for rehabilitation of lower extremity injuries. KBA combined with strength training (ST) reportedly improves function among persons with knee osteoarthritis (OA), but independent effects of KBA are unknown. The purpose of this study was to determine the efficacy of KBA exercises, independent of ST, to improve function among persons with knee OA. Twenty participants (69.3, SD 11.4 y) were randomized to 8 weeks, 3-days per week, instructor-lead KBA or ST groups. Self-reported physical function (difficulty with daily living activities such as walking, bending, stair climbing, etc.) was measured ...

The Effect Of Energy Patches On Substrate Utilization In Collegiate Cross-Country Runners, Ryan E. Fiddler, Doug Smith, Bert Jacobson, Crishel Klein, Aric Warren, Matt O'Brien, Brennan Thompson, Lee Everett

International Journal of Exercise Science

It is well established that an increased capacity of skeletal muscle to oxidize fatty acids can spare glycogen and delay the onset of fatigue in mild- to moderate-intensity exercise. The purpose of the following study was to examine the effect of LifeWave® energy patches on non-protein substrate utilization in Division-1 cross-country runners. To determine the effect of the patches subjects were pretested to establish baselines and randomly assigned to an experimental (EX) or placebo (PL) group. Twenty-two trained male (n = 11; mean ± SD, age = 21.1 ± 2.6years, height = 179.6 ± 4.2cm, body mass = 71.4 ± 7.4kg, VO2max ...


Physical Activity And Screen Time Sedentary Behaviors In College Students, Charles J. Fountaine, Gary A. Liguori, Arupendra Mozumdar, John M. Schuna Jr. 2011 South Dakota State University

Physical Activity And Screen Time Sedentary Behaviors In College Students, Charles J. Fountaine, Gary A. Liguori, Arupendra Mozumdar, John M. Schuna Jr.

International Journal of Exercise Science

It is well established that Americans are not meeting physical activity (PA) guidelines and college students are no exception. Given the lack of regular PA, many health promotion professionals seek to discover what barriers to PA may exist. A common explanation is screen time (ST), which is comprised primarily of television viewing, computer use, and the playing of video games. The purpose of this study was to present descriptive data on college students’ PA and sedentary behavior and to assess if any evidence exists to suggest displacement between sedentary behaviors and PA in college students. Students completed an online health ...

Accuracy Of The Omron Hbf-500 Body Composition Monitor In Male And Female College Students, Michael I. Pribyl, John D. Smith, G Richard Grimes

International Journal of Exercise Science

The Omron HBF-500 is an inexpensive body composition monitor that incorporates both hand-to-hand and foot-to-foot electrical impedance technology. At this time, studies examining the accuracy of the HBF-500 when estimating percent body fat (%BF) are scarce and if this instrument gains popularity due to its claimed precision, comparisons against validated techniques should be conducted. The purpose of this study was to assess the accuracy of the Omron HBF-500 body composition monitor using the BOD POD as a criterion. Forty-eight men and 33 women participated in the study (24.3±6.9 years, 171.0±10.0 cm, 78.4±18 ...


Child Obesity In Context: Ecology Of Family And Community, Joel E. Williams 2011 Clemson University

Child Obesity In Context: Ecology Of Family And Community, Joel E. Williams

International Journal of Exercise Science

Minority and low socioeconomic status groups have the highest rates of overweight and obesity. Children from these families face a greater risk for weight-related health problems such as diabetes, heart disease and cancer as compared to their non-minority and more affluent peers. Factors from the larger physical, social, and cultural environments, and within families, influence weight status among children. Many of these factors are yet to be identified and relationships among known factors are complex and not well understood. The National Institutes of Health and U.S. Department of Agriculture have proposed a research agenda for social and behavioral scientists ...

International Journal of Exercise Science: Conference Proceedings

High-fat feeding and subsequent weight gain may contribute to innate immune dysfunction. Weight loss via calorie restriction and exercise represent one means to restore normal immune function. The purpose of the study was to examine how 8- weeks of aerobic exercise and low-fat diet affects weight gain, monocyte concentration, and monocyte cell-surface expression of TLR2, TLR4, CD80, and CD86. For 12- months, 24 male CD-1 mice underwent a pre-treatment phase, consuming either a low fat (10% fat) or high-fat (60% fat) diet ad libitum. Mice were randomly assigned to one of four groups (N=6/group): CN (low-fat sedentary), V-EX ...
