Changes In Peak Acceleration In The Snatch Across Multiple - Attempts In Training: A Case Study, George K. Beckham, Kimitake Sato, Timothy J. Suchomel, William A. Sands, Michael H. Stone

ETSU Faculty Works

Accelerometers are devices that have been recently used to assess the performance of weightlifters in training. This case study used vertical acceleration data to assess multiple snatch attempts in a single lifter during a training session. The lifter exhibited variability in a number of measures, including peak acceleration and peak velocity. The measures calculated from the acceleration-time data did not show consistent trends between made and missed lifts. More work is needed identify variables of interest for snatch performance.

Longitudinal Monitoring Of Countermovement Jump Mechanical Variables: A Preliminary Investigation, Christopher J. Sole, Satoshi Mizuguchi, Timothy J. Suchomel, William A. Sands, Michael H. Stone

ETSU Faculty Works

The purpose of this study was to examine the influence of accumulated volume load on countermovement jump (CMJ) mechanical variables. Eight athletes underwent weekly CMJ testing using a force plate. Statistical changes were observed in certain CMJ variables over the observation period. Jump height (0.42±0.05 m) and allometrically scaled peak power (88.86±7.49 W·kg-0.67) exhibited multiple statistical changes. These changes appeared to exhibit a delayed effect in response to accumulated volume load. Specifically, following several weeks of large accumulated volume loads these variables declined. In addition subsequently decreasing accumulated volume loads resulted in an increase in both variables. The findings of …

Ask any athlete how she got to where she is today. Did she play on an Olympic Development Team (ODP), or did she get recruited from a showcase tournament? There are a variety of paths when trying to play collegiate soccer, and one path is not better than the other. Even the thirty girls on the same college team may experience a vastly different recruiting process, but, somehow, they all end up in the same place. This paper offers mere overall guidance to the recruiting process for female high school soccer players, with helpful tips to use along the way. …

Inactive To Active: A Positive Life Change, William Mclachlan

Senior Theses

Not only has research unanimously supported the claim that physical activity is good for you, it is an idea that many people see as wide-spread enough to be considered banal. However, at a time when the United States is facing rising rates of obesity (Haskell et al., 2007), it is important to appreciate the importance of that information. In order to gain a personal understanding of the importance of physical activity, I engaged in resistance training five days per week and an additional four hours and 40 minutes, on average, of other physical activities, including yoga, stretching, and tennis, for …

Lower Body Kinematic Comparisons Between Front And Back Squats In Response To Loads, Joosung Kim

Master’s Theses and Projects

The squat is considered as one of the most popular exercises prescribed by therapists, athletic trainers, researchers, coaches, and athletes for injury prevention and strength and conditioning. People commonly associate the squat exercise as the back squat. However, the front squat has been advocated to reduce the stress to the lower back while increasing the leg strength. The proper front squat technique and the changes in the spine and lower extremity joints in response to load mass are still unclear. Therefore, the purpose of this study was to examine the lower body kinematic comparisons between front and back squat exercises …

Athletic Trainers' Knowledge And Perceptions Of Testicular Cancer And Testicular Cancer Prevention Practices, Christopher Mings

HIM 1990-2015

Context: Collegiate male athletes have a higher risk of testicular cancer due to their age group, an increased risk of testicular contusions, and a lack of secondary prevention education. As the athletic training profession increases emphasis on evidence-based practice, it is important for athletic trainers to understand testicular cancer and testicular-self examination as it is outlined within their scope of practice. A general understanding of testicular cancer and the prevention techniques will be important for athletic trainers to promote awareness and health behavior practices. Objective: To examine the athletic trainers' actual knowledge, concern, perceived responsibility, training, feeling of embarrassment, and …

The Effect Of Winter Versus Summer Running On Lower Extremity Musculoskeletal Injury Rate In Recreational Runners, Elizabeth Frieseke

All NMU Master's Theses

The effects of cryotherapy on body tissues suggest that cold exposure can decrease performance measures, including proprioception, strength, and agility. Since a decrease in proprioception and strength have been linked with an increase of injury rates, this suggests that exposure to cold conditions may increase injury rates. The main purpose of this study was to determine if there is a difference in musculoskeletal injury rates in the winter compared to the summer months in recreational runners. The participants were surveyed on their injury history for the past year. The results of this study showed that the injury rate for musculoskeletal …

Acute Effects Of Long Distance Running On C-Reactive Protein And Arterial Stiffness, Bridget E. Durocher

All NMU Master's Theses

Abstract

Central arterial stiffness, indicated by pulse wave velocity (PWV), is increased during the hour post ultramarathon (ULT), but it's currently unknown if PWV remains elevated 24 hours after ULT or marathon (MAR). PURPOSE: To determine the effects of ULT and MAR on C-reactive protein (CRP), aortic blood pressure (BP), aortic augmentation index (AIx), PWV, and LF:HF ratio. We hypothesized that CRP, AIx, PWV and LF:HF ratio would be elevated 24 hours post-race. Our secondary hypothesis was that changes in PWV would be inversely correlated to the percentage of moderate activity (3-6 METs) during competition. METHODS: Applanation tonometry was used …

The Effect Of Repeated Mild Traumatic Brain Injury On Ventricular Volume And Microglial Activation, Lillian Rose Talbot

Honors Scholar Theses

As the leading cause of death and disability in individuals under the age of 45-years-old, Traumatic Brain Injury (TBI) is a public health crisis that demands the attention of the scientific and medical community [28]. The majority of all TBIs that occur in the United States each year are a non-deadly yet detrimental form of closed brain injury known as mild TBI (mTBI) or concussion [6]. Athletes, young people and military personnel all face a high risk of acquiring mTBI as a result of their environments. In our study we have chosen to model repeated mTBI (rmTBI) in the mouse …

Masters Theses and Doctoral Dissertations

The purposes of this study were: • to develop a prediction model to identify factors associated with eligibility and first-attempt success on the Board of Certification (BOC) examination for students enrolled in a professional (entry-level) graduate athletic training program (GATP) • to identify applicant characteristics that are most likely to predict both academic success in the GATP and success on the BOC exam. A cohort of 119 students was used for both purposes. Multiple analyses yielded three-factor and two-factor models for prediction of passing the BOC exam. The three-factor model demonstrates that a student with ≥ 2 predictors had an …

Use Of Audio Biofeedback To Reduce Tibial Impact Accelerations During Running, Claire M. Wood, Kristof Kipp

Exercise Science Faculty Research and Publications

Visual biofeedback of tibial peak positive acceleration (PPA) during running has been used successfully as a method of gait retraining to reduce PPAs. Audio biofeedback generated from PPA may present a novel, portable alternative. The purpose of this study was to investigate the feasibility of using PPA-generated audio biofeedback to reduce PPAs while running. Nine runners were fitted with a wireless accelerometer on their left tibia. PPAs were recorded and a custom LabVIEW program was used to emit a single beep once the PPA reached a preset threshold. The numerical difference between this threshold and peak PPA during running was …

Refeeding Syndrome In A Young Girl With Anorexia Nervosa., Om Parkash, Adil Ayub, Shahab Abid

Department of Medicine

We report the case of a 20-year-old anorexic girl (BMI=12.9), who was misdiagnosed the first time and developed severe electrolyte imbalances due to lack of awareness about refeeding syndrome. Few cases of RS have been reported in literature and protocols have been suggested for prevention and management of this syndrome, including the awareness of circumstances in which it is most likely to develop, refeeding slowly and building-up micronutrient content over several days. Improved awareness and understanding of refeeding syndrome along with a well-coordinated plan are vital in delivering safe and effective nutritional rehabilitation. We suggest a slow and gradual increase …
