Electromyographical Comparison Of A Traditional, Suspension Device, And Towel Pull-Up, Ronald L. Snarr, Ashleigh V. Hallmark, Jason C. Casey, Michael R. Esco

Department of Health Sciences and Kinesiology Faculty Publications

Strengthening muscles of the back may have various implications for improving functions of daily living, aiding in the transfer of power in throwing, and assist in injury prevention of the shoulder complex. While several versions of the pull-up exist, there is currently no literature comparing their differences. The purpose of this investigation was to compare the electromyographical activity of the latissimus dorsi, posterior deltoid, middle trapezius, and biceps brachii while performing three variations of the pull-up. Resistance-trained men and women (n = 15, age = 24.87 ± 6.52 years) participated in this study by performing traditional pull-ups, suspension device pull-ups, …

Weak Relationships Between Three Clinical Assessments And Core Stability Tests, Andy Waldhelm, Li Li

Department of Health Sciences and Kinesiology Faculty Publications

Core stability measurements are commonly used to identify individuals who may be at risk for athletic injuries. However, the relationship between core stability tests and other clinical assessments used to assess injury risk are not well established. The purpose if this study is to determine the relationships between three clinical assessments and core stability tests. We anticipate the relationships between the three clinical assessments and core stability tests will be low and not significant. Participants included 36 college-aged males and females. The three clinical assessments consisted of the Star Excursion Test and the Frontal Plane Projection Angel (FPPA) of the …

Parallel And Cross-Sectional Hamstring Injuries In Sprint Running, Li Li, Donghai Wang

Department of Health Sciences and Kinesiology Faculty Publications

This issue of Journal of Sport and Health Science contains a point-counterpoint discussion of hamstring injuries in sprint running by the groups of Drs. Liu and Yu.^1–4 They propose different mechanisms of muscle injuries in general, and hamstring injuries in sprint running specifically. Yu et al.^2,4 present evidence suggesting that hamstring injuries are primarily caused by excessive muscle strain during eccentric contraction. In maximal effort sprint running, excessive muscle strains occur at the end of the swing phase. In contrast, Liu et al.^1,3 point out that, in addition to excessive hamstring strain, high stresses in the late …

Innovative Running Related Researches, Li Li

Department of Health Sciences and Kinesiology Faculty Publications

There was a surge in published research related to barefoot running in the past 2 decades, and especially in the past 5 years. For example, the number of returns for “barefoot running” in Google Scholar increased dramatically relative to the search returns for “running” (Fig. 1). “Running” related returns started at about 220,000 in 1997 and peaked at about 376,000 in 2007 (a 0.7 times increase) and gradually decreased to less than 70,000 in 2016. In contrast, “barefoot running” related returns started at 945 in 1997 and peaked at 5010 in 2012 (a 4.3 times increase). Between 2007 and 2012, …

Urban Versus Rural Differences In Insurance Coverage And Impact On Employment Among Families Caring For A Child With Cerebral Palsy, Braydon Schaible, Gavin T. Colquitt, Li Li, Manuela C. Caciula, Noelle G. Moreau

Department of Health Sciences and Kinesiology Faculty Publications

Background: The purpose of this study was to examine urban vs. rural differences on the relationship between family contextual variables and adequacy of insurance coverage and impact on employment for among families with a child with Cerebral Palsy from a nationally representative sample.

Methods: A retrospective, observational study was carried out using data from the National Survey of Children with Special Healthcare Needs.

Results: A total of 744 participants reported as having a child with a diagnosis of Cerebral Palsy and were included in the sample. Logistic regression analyses, adjusting for urban and rural setting revealed different predictors of adequacy …

The Effect Of Repetitive Head Impacts On Postural Control Over The Course Of A Single Season, Katelyn E. Grimes

Electronic Theses and Dissertations

INTRODUCTION: Recently neurocognitive dysfunction has been linked to poor postural control in concussed athletes. While the detrimental effect of repetitive head impacts on cognitive function have been shown to mirror the effects of concussive injury, very little research has investigated the physical consequences of repetitive head impacts. PURPOSE: To observe the effects of RHI on postural control, both static and dynamic, in NCAA Division I athletes over the course of a single season. METHODS: 9 NCAA Division I football athletes (CON) were recruited from a single university as the experimental group, as well as 9 NCAA Division I baseball players …

Heart Rate Recovery And Blood Pressure Recovery Influenced By A Slow-Breathing Protocol After Exercise In Moderately Trained Females, Emily Layne Zumbro

Electronic Theses and Dissertations

Heart rate (HR) and blood pressure (BP) increases in order to meet metabolic demands as a result of exercise primarily through way of the sympathetic nervous system (SNS) and parasympathetic nervous system (PNS). This study aimed to build on previous research in finding the best method to rapidly decrease HR and BP after exercise during the recovery period. PURPOSE: The purpose of this study was to determine the effectiveness of a breathing technique on HRR and BPR within a healthy female population during an exercise recovery period compared to active recovery and upright passive recovery. METHODS: Nine moderately trained female …

The Reliability Of The Navicular Drop Test And Its Transferability To Dynamic Movement, Joshua Krispin

Electronic Theses and Dissertations

Background: Navicular drop can be defined as the distance the navicular tuberosity moves from a standing weight bearing to a standing neutral position, as the subtalar joint moves from a relaxed position to a neutral position. Navicular drop is an important measurement for clinicians used to describe foot function, pronation, and excessive movement seen in several pathologies. Objective: The purpose of this study is to see if navicular drop is influenced by mode or speed of locomotion, if it is will there be other influences such as the forefoot and heel soft tissue, and will those factors influence those measures. …

The Effects Of Beetroot Juice On Vo2max And Blood Pressure During Submaximal Exercise, Jose M. Perez

Electronic Theses and Dissertations

Supplementation with beetroot juice (BR) has been shown to reduce blood pressure (BP) at rest and improve several performance parameters during submaximal and maximal exercise. BR effects on BP during submaximal exercise have not been investigated. Furthermore, the effects of BR on VO₂max are inconclusive. The purpose of this study was to investigate the effects of BR on VO₂max and BP during submaximal exercise. 20 healthy, recreationally trained volunteers (age 21.8±2.35 years, weight 75.10±10.62 kg, height 177.4±6.39 cm) participated in this study, which had a double-blind placebo controlled randomized crossover design. Participants began supplementation with either …

An Examination Of Spasticity Of The Lower Extremity Among Young People With Cerebral Palsy, Jordan Nourse

Honors College Theses

Background: Spasticity is the most common symptom among individuals with Cerebral Palsy (CP). Spasticity is often presented as stiff limbs often resulting in pain. Currently, clinicians are limited in diagnosing spasticity using observational tools. The purpose of this study was compare spasticity at various functional levels using dynamometry. Methods: Participants included nine adolescents (12-19) with CP and nine adolescents (age-matched) without CP. The participants participated in passive stretches delivered by the Biodex System 4 Pro Dynamometer at four different speeds (90, 120, 150, and 180 deg/s), Measurements of the quadriceps will be collected before and during passive knee extension stretches …
