A Comparison Of The Effects Of Static Stretching With And Without Whole Body Vibration On Hip Flexion Range Of Motion In College Age Males, Jessica Lynn Wilson

Masters Theses

The purpose of this study was to compare the effects of a single bout of static stretching with and without whole body vibration on hip flexion range of motion in college age males. A second purpose was to determine whether any acute effects would persist after one hour of rest. It was hypothesized that there would be a significant increase from baseline to posttest hip range of motion with both static stretching only and static stretching with whole body vibration. Further, the improvement would be significantly greater with the addition of whole body vibration. It was also hypothesized that any …


Development And Validation Of The Anterior Cruciate Ligament Injury-Risk-Estimation Quiz (Acl-Iq), Erich J. Petushek Jan 2014

Development And Validation Of The Anterior Cruciate Ligament Injury-Risk-Estimation Quiz (Acl-Iq), Erich J. Petushek

Dissertations, Master's Theses and Master's Reports - Open

Over 2 million Anterior Cruciate Ligament (ACL) injuries occur annually worldwide resulting in considerable economic and health burdens (e.g., suffering, surgery, loss of function, risk for re-injury, and osteoarthritis). Current screening methods are effective but they generally rely on expensive and time-consuming biomechanical movement analysis, and thus are impractical solutions. In this dissertation, I report on a series of studies that begins to investigate one potentially efficient alternative to biomechanical screening, namely skilled observational risk assessment (e.g., having experts estimate risk based on observations of athletes movements). Specifically, in Study 1 I discovered that ACL injury risk can be accurately …


Comparison Of Two Different Sprint Interval Training Work-To-Rest Ratios On Acute Metabolic And Inflammatory Responses, Christopher R. Harnish Jan 2014

Comparison Of Two Different Sprint Interval Training Work-To-Rest Ratios On Acute Metabolic And Inflammatory Responses, Christopher R. Harnish

Theses and Dissertations

High intensity exercise is believed to yield greater results on health and human performance than moderate intensity exercise. Extensive research indicates that not only do high-intensity interval training (HIT) and sprint interval training (SIT) produce significant improvements in cardiovascular fitness and disease, they may be more effective at improving long-term metabolic function, including insulin sensitivity (Si), by producing more mitochondria. Moreover, compliance rates for HIT and SIT participation are reported to be the same or better than traditional moderate intensity exercise. Because lack of time is often cited as major hindrance to exercise participation, SIT is also seen as a …

To test this, two loading conditions (15% and 25% of 1RM) were used and each resistance load was added to a base of 60% of 1RM free weights. Twelve recreationally trained male …


The Acute Influence Of Occupational Footwear On Balance, Caroline Borland Jan 2014

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 …


A Method To Optimize A Typology-Based Classification System, Christopher Schnitzler, James Croft, Chris Button, Mats Ulmers, Keith Davids Jan 2014

A Method To Optimize A Typology-Based Classification System, Christopher Schnitzler, James Croft, Chris Button, Mats Ulmers, Keith Davids

Research outputs 2014 to 2021

This study sought to provide guidelines for implementing typology-based qualitative analysis of human movement patterns. Fifteen participant-analysts were instructed how to classify treading water behaviours into eight different categories using a training set of videos. They were later provided with two additional sets of videos called validation, and test sets. Results first identified reliable (n=9), and not reliable (n=6) analysts. A decision study outlined that one analyst was sufficient to reliably categorize the behaviours in the 'reliable' analyst group, whereas up to four were necessary in the 'unreliable' group. These data provided new insights into more objective qualitative analysis methods …


Laterality Across The Lifespan: The Effects Of Task Complexity, Nicole Williams Jan 2014

Laterality Across The Lifespan: The Effects Of Task Complexity, Nicole Williams

Theses and Dissertations (Comprehensive)

The current study aimed to build on the work of Gooderham & Bryden (2013) by comparing the effects of task complexity on hand selection across the lifespan. It was hypothesized that the increasing complexity of a task would override a biomechanically efficient movement such that participants would use only the preferred hand to complete the task. It was also hypothesized that older adults would perform similarly to young children with respect to switch points in space. Four age groups of participants (3-7 year olds, 8-12 year olds, 18-25 year olds and adults over 70 years) completed the newly designed Hand …


Comparison Of Automated Event Detection Algorithms In Pathological Gait, Dustin A. Bruening, Sarah Trager Ridge Jan 2014

Comparison Of Automated Event Detection Algorithms In Pathological Gait, Dustin A. Bruening, Sarah Trager Ridge

Faculty Publications

Accurate automated event detection is important in increasing the efficiency and utility of instrumented gait analysis. Published automated event detection algorithms, however, have had limited testing on pathological populations, particularly those where force measurements are not available or reliable. In this study we first postulated robust definitions of gait events that were subsequently used to compare kinematic based event detection algorithms across difficult pathologies. We hypothesized that algorithm accuracy would vary by gait pattern, and that accurate event detection could be accomplished by first visually classifying the gait pattern, and subsequently choosing the most appropriate algorithm. Nine published kinematic event …

An Examination Of Behavioral And Temporal Consistency Of Pre-Performance Routines In Ncaa Division I Basketball Free Throw Shooting – A Naturalist Observational Investigation, Jacob Blumberg Jan 2014

An Examination Of Behavioral And Temporal Consistency Of Pre-Performance Routines In Ncaa Division I Basketball Free Throw Shooting – A Naturalist Observational Investigation, Jacob Blumberg

College of Graduate Studies: Theses & Dissertations

Research has shown that pre-performance routines positively influence performance of closed and self-paced skills (Boutcher & Crews, 1987; Cohn, 1990; Otto et al., 2011). Boutcher and Crews (1987) suggested that pre-performance routines improve performance by helping reduce anxiety along with helping athletes’ retain mental sharpness and focus. Furthermore, several quantitative studies have examined the influence of both behavioral and temporal consistency of pre-performance routines on the success of a skill, yielding inconsistent results (Boutcher & Crews, 1987; Lobmeyer & Wasserman, 1986; Lonsdale & Tam, 2008; Jackson, 2003). However, research examining this phenomenon from a qualitative and naturalistic observational perspective is …

Effects Of Electrical Pulse Stimulation On In Vitro Measurement Of Mitochondrial Content And Lipid In Human Myotubes, Daniel Alberto Conde

Open Access Theses & Dissertations

It has been previously shown that human myotubes retain certain in vivo characteristics of the donors. Furthermore, we have shown that Electrical pulse stimulation (EPS), an in vitro exercise mimetic, increases mitochondrial and lipid content in cultured human myotubes after 24 hr. of stimulation. Purpose: We aimed to examine the EPS induced adaptations to lipid, mitochondrial, and Glucose transporter 4 (GLUT4) content using human myotubes. Methods: EPS was applied to myotubes for 60 min (bipolar pulses of 100 Hz, 30V, every 5 seconds), 24 hr. or 48 hr. (single bipolar pulses of 1 Hz for 2 ms; 30V) and were …


Evaluation Of Static And Dynamic Postural Control In Athletes With Concussions During Recovery, Nicholas Murray Jan 2014

Evaluation Of Static And Dynamic Postural Control In Athletes With Concussions During Recovery, Nicholas Murray

Open Access Theses & Dissertations

Approximately seventy-six percent of individuals with a sport-related concussion present with reduced balance. Current Return-to-Play (RTP) protocols rely heavily on measures of static balance that are not environmentally relevant. However, due to the variable nature of symptom presentation, research has not clearly defined a requisite time for balance recovery following a sport-related concussion. The use of novel procedures such as monitoring postural control during an environmentally relevant dynamic balance tasks could refine the timeline for recovery of postural control and aid in mitigating the potential severe consequences of Second Impact Syndrome. Therefore, the purpose of this study was to investigate …


Modulation Of Vestibular Evoked Reflexes In Postural Muscles During Self-Motion Experiences In Virtual Environments, Fabricio Saucedo Jan 2014

Modulation Of Vestibular Evoked Reflexes In Postural Muscles During Self-Motion Experiences In Virtual Environments, Fabricio Saucedo

Open Access Theses & Dissertations

BACKGROUND & AIM: Maintaining posture requires the input from three primary sensory systems. These systems include somatosensory, visual, and vestibular components. Of these three systems, the visual and vestibular systems work closest to maintain balance and posture due to visual-vestibular interactions that take place during static and dynamic activities. They are mainly responsible for identifying stimuli and using sensory information to orient the body in space. Thus, understanding how visual and vestibular components integrate may be critical to understand how visual and vestibular sensory information is weighted to control balance. The purpose of this investigation was to determine if visual …


Examining The Role Of Attention In Steering Using A Dual Task Paradigm, Venkata Naga Pradeep Ambati Jan 2014

Examining The Role Of Attention In Steering Using A Dual Task Paradigm, Venkata Naga Pradeep Ambati

Open Access Theses & Dissertations

Changing the direction of locomotion, often referred to as "steering", is an integral component of human locomotion. Steering requires maintaining dynamic balance while translating and rotating the body in the new travel direction. Given the level of sensation thought to be involved in sub serving goal directed modifications in steering, it is highly likely that steering control may require attention. Since attention resources decline with increasing age, we may see the influence of age on steering performance when attention resources are limited. Therefore, this study sought to investigate the role of attention in steering using a dual task paradigm in …

Kinesiology Student Research - Archive

INTRODUCTION: Energy drinks have become the soft drink of this millennium. They are commonly available everywhere including stores, schools and fitness centers. Yet, the effects of energy drinks, on metabolism at rest and during exercise, receive little attention. Ingredients in energy drinks such as caffeine and taurine are sympathetic stimulants and increase heart rate and blood pressure. However, it is unclear as to whether or not these effects actually improve exercise performance. Redbull is an example of an energy drink that is often consumed with the idea that it will improve performance during an exercise workout. PURPOSE The purpose of …

The Effects Of Caffeine On Blood Lactate Levels During Submaximal Exercise, Sara Cleveland Dec 2013

The Effects Of Caffeine On Blood Lactate Levels During Submaximal Exercise, Sara Cleveland

Kinesiology Student Research - Archive

INTRODUCTION: Blood lactate concentration reflects the balance between lactate production and clearance. It is considered a marker of exercise intensity and muscle glycolysis. It is expressed in mmol/L of lactate found in the plasma of blood. Research shows that caffeine, a stimulant with ergogenic properties, increases blood lactate levels. It is also shown to improve aerobic performance and increase time to exhaustion during exercise. The physiological underpinnings of caffeine-provoked endurance performance gains are not yet fully understood but may be related to enhanced calcium availability, adenosine receptor antagonism and consequential reductions in pain and perceived exertion, and augmented lipolysis and …


Physical Stress On The Body Using A Vo2 Max Test And Its Effects On Short-Term Memory In Male Students, Kimberly Alvarez Dec 2013

Physical Stress On The Body Using A Vo2 Max Test And Its Effects On Short-Term Memory In Male Students, Kimberly Alvarez

Kinesiology Student Research - Archive

Introduction. Research shows that rhythmic exercise changes in serotonin, epinephrine, norepinephrine and acetylcholine levels all affect cortical arousal and cognitive function (Potter & Keele, 2005). There are many reasons why the brain is affected during exercise. Some of these include: increased glucose, oxygen and nutrient levels to the brain. Exercise has been shown to enhance cognitive function in both short and long term memory. However, when the body is put under a large amount of physical stress, less oxygen is left in the brain due to the fact that the muscles require more of that oxygen and glucose. Does this …

The Effects Of Caffeine Consumption On The Blood Lactate Levels In Recreationally Active College-Aged Males, James S. Hoerig

Kinesiology Student Research - Archive

INTRODUCTION: Caffeine has become the most widely used drug in the world. This xanthene derivative causes an increase in catecholamines circulating throughout the blood, and is commonly used by athletes looking for an increase in athletic performance. Besides having a stimulating effect on the cardiovascular and nervous system, many report a decrease in their levels of perceived exertion while performing exercise in conjunction with the drug. Blood lactate is a common way to quantify objectively the levels of exertion an athlete may be experiencing during exercise, as it is shown to increase linearly with perceived exertion and muscular fatigue. Additionally, …
