A Comparison Of Multipath And Conventional Neuromuscular Electrical Stimulation, Cody Brian Bremner 2016 University of Southern Mississippi

A Comparison Of Multipath And Conventional Neuromuscular Electrical Stimulation, Cody Brian Bremner

Dissertations

Neuromuscular electrical stimulation (NMES) is the use of an electrical current for the purpose of eliciting a muscular response, and these treatments are most often used clinically for the specific purpose of increasing quadriceps strength. It is commonly accepted that the effectiveness of NMES for this purpose is primarily determined by the NMES training intensity. However, spatially limited motor unit recruitment, fatigue and discomfort negatively impact NMES-induced torque, which subsequently reduces NMES training intensities. Due to the importance of NMES training intensity, a substantial amount of research has focused on strategies designed to increase NMES-induced torque production, as well as ...

The Neuroprotective Effects Of Endurance Training On The Aging Brain, Katelyn Norton 2016 The University of Western Ontario

The Neuroprotective Effects Of Endurance Training On The Aging Brain, Katelyn Norton

Electronic Thesis and Dissertation Repository

Dysregulation of autonomic control often develops with advancing age, favoring a chronic state of heightened sympathetic outflow with parasympathetic withdrawal. However, the mechanisms of this age-related autonomic impairment are not known and may relate to alterations in brain structure (e.g. cortical atrophy) and/or altered neural function, particularly in regions related to the cortical autonomic network, namely, the medial prefrontal cortex (MPFC), insula cortex (IC), and hippocampus (HC). Exercise exerts beneficial effects on brain structure and, in the case of cognition, neurologic function; however, how exercise affects regions of the brain related to autonomic function are not known. This ...


Exercise To The Rescue: An Analysis Of Altered Metabolic Gene Regulation Post-Exercise In Lean And Obese Individuals, Brandon Mudd 2016 Western Kentucky University

Exercise To The Rescue: An Analysis Of Altered Metabolic Gene Regulation Post-Exercise In Lean And Obese Individuals, Brandon Mudd

Honors College Capstone Experience/Thesis Projects

The skeletal muscle of obese individuals exhibits a depressed ability to metabolize fats. Exercise training is thought to rescue this dampened ability to metabolize fats; mediated by a coordinated increase in the expression of a network of genes that regulate metabolism and fuel utilization. The purpose of this study is to determine the exercise-induced regulation of metabolically important genes in lean and obese individuals. Muscle biopsies (one pre-exercise/baseline and one immediately post-exercise) were obtained from 4 lean (BF% 24.4 ± 5.5; 23.5 yrs ± 1.9) and 13 obese (BF% 39.7 ± 2.4; 26.1 yrs ± 2 ...

Effect Of Modified Corn Starch Ingestion On Soccer Skills And Physical/Cognitive Performance During A Simulated Soccer Game, Manuel D. Quinones

Electronic Thesis and Dissertation Repository

Abstract

Generation UCAN® (UCAN), which contains heat treated non Genetically Modified Organism (GMO) corn starch, has the potential to enhance endurance exercise performance via altering substrate use; however, whether its effects are similar during high intensity, intermittent exercise, like that performed in soccer is unknown. Therefore, the purpose of this study was to assess the effects of UCAN on physical, skill and cognitive performance during and following a simulated soccer game. Eleven trained male soccer players completed a 60-min soccer simulated game on a treadmill, under two experimental conditions: UCAN and an isoenergetic carbohydrate (CHO) placebo. There were no significant ...


Constraining Kinematics During Single-Leg Squats And Step-Ups Can Reduce Quadratus Lumborum Activation And Facilitate Gluteal Activation, Shaylyn Kowalchuk 2016 The University of Western Ontario

Constraining Kinematics During Single-Leg Squats And Step-Ups Can Reduce Quadratus Lumborum Activation And Facilitate Gluteal Activation, Shaylyn Kowalchuk

Electronic Thesis and Dissertation Repository

Increased quadratus lumborum activation and decreased gluteal activation may lead to lateral pelvic drop and increased hip adduction and internal rotation during single-leg exercises. These activation patterns and motions are associated with low back pain or lower extremity injuries. The purpose of this study was to evaluate if mechanically restricting hip adduction and internal rotation of the femur affected muscle activation. Twenty female track and field athletes performed single-leg squats and step-ups, and the quadratus lumborum, gluteus medius and maximus muscles activations were measured with surface electromyography. This study tested the hypothesis that mechanically restricted exercises would decrease quadratus lumborum ...

An Activity Index For Raw Accelerometry Data And Its Comparison With Other Activity Metrics, J Bai, C Z. Di, L Xiao, K R. Evenson, A Z. Lacroix, C M. Crainiceanu, D M. Buchner

Chongzhi Di

Accelerometers have been widely deployed in public health studies in recent years. While they collect high-resolution acceleration signals (e.g., 10-100 Hz), research has mainly focused on summarized metrics provided by accelerometers manufactures, such as the activity count (AC) by ActiGraph or Actical. Such measures do not have a publicly available formula, lack a straightforward interpretation, and can vary by software implementation or hardware type. To address these problems, we propose the physical activity index (AI), a new metric for summarizing raw tri-axial accelerometry data. We compared this metric with the AC and another recently proposed metric for raw data ...

The Physiological Responses To Cycling Stress., Moriah Larsen

Skyline - The Big Sky Undergraduate Journal

Background: As the intensity of exercise increases, the risk of incidences for exertional heat illness (EHI) continues to climb. The National Athletic Trainers Association (NATA) has set an official position statement; stating a “gold standard” for obtaining core body temperature is via rectal thermometry. It has been reported that other field-expedient methods of obtaining core body temperature (oral, axillary, tympanic, temporal) are invalid or unreliable sources after intense exercise in hot temperature regions. Purpose: To determine if a relationship exists between rectal temperature measurements and tympanic temperature measurements during intensive long bouts of exercise. Design: Controlled Laboratory Study. Setting: Human ...

Furthermore, evaluation of potential differences in personality traits between successful and unsuccessful students has not been explored. Identifying NEO-FFI-3 traits correlated to ATP student outcomes may result in academic interventions as well as improve student success and retention. Purpose: To establish the mean NEO-FFI-3 scores of students admitted to ATPs. To assess if differences exist in NEO-FFI-3 scores between successful students (retained in ATP or passed the BOC Exam) and non-successful students (released from the ATP). Design: Survey research. Setting: Students admitted ...


An Evaluation Of The Relationship Between Core Endurance And Lower Extremity Strength, And The Ability To Recover After Perturbation, Carlie Jones-Hershinow 2016 University of Northern Colorado

An Evaluation Of The Relationship Between Core Endurance And Lower Extremity Strength, And The Ability To Recover After Perturbation, Carlie Jones-Hershinow

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

Previous research suggests core strength training improves anticipatory postural adjustments, reducing one’s risk of a fall, and stronger core muscles lead to faster reaction times. This study investigated whether core endurance and lower extremity strength relate to the time one needs to stabilize after being perturbed. An evaluation of ten participants while warming up determined each participant’s transition speed between walking and running. While each participant walked at his/her transition speed, the belts were stopped randomly at an acceleration rate of

2.7 m∙s-2 and ground reaction forces were recorded during balance recovery. Additionally, each ...

Ball Pressure Correlations With Peak Impact Force And The Potential For Cumulative Mtbi When Heading A Soccer Ball, Nicolas Leiva, Daniel Y. Shyu, Josh Auger, Eric Nauman

The Summer Undergraduate Research Fellowship (SURF) Symposium

Soccer is a unique sport in which athletes use their heads as tools for gameplay, which may ultimately cause cumulative traumatic brain injuries. Due to rising popularity of soccer in the United States alongside the increased occurrence of CTE and mTBI in other contact sports, there is a growing concern over how to keep the repetitive forces caused by heading, as low as possible. Different variables that can affect the peak force felt when heading a soccer ball can be simulated and compared with in-game data, however, this has never been properly tested before. In the present study two size ...

Development Of Standard Criteria To Evaluate The Effectiveness Of Helmets At Decreasing The Risk Of Concussions, Daniel Y. Shyu, Goutham N. Sankaran, Kevin G. Mciver, Nicolas Leiva, Eric A. Nauman

The Summer Undergraduate Research Fellowship (SURF) Symposium

In many sports, such as American football, accumulations of mild traumatic brain injuries have been suggested as a possible link to neurodegeneration and future mental disorders. With head impacts occurring at all levels of competition and in different sports, it is critical to develop an accurate method for quantifying the effects of head impacts and determining the efficacy of helmets. This study examines the derivation of different dimensionless numbers and ascertains the critical factors needed to predict the effects of head impacts, specifically the resulting accelerations from an impact. Given a known force of impact, parameters such as peak translation ...
