Non-Steroidal Anti-Inflammatory Drug Use In Collegiate Athletes, Brian Robert Davis

Dissertations and Theses

Non-steroidal anti-inflammatory drugs (NSAID) are a class of medications used in the treatment of pain, inflammation, and illness. These medications are common, affordable, and easy to access. For these reasons, NSAIDs are commonly used by athletes of all backgrounds for treating injuries and as ergogenic aids. However, despite these behaviors, NSAIDs have well-documented side effects and the efficacious nature of these medications has been brought into question. Despite this, many athletes continue to use these medications frequently and indiscriminately. It is not known why athletes use these medications in light of their questionable effectiveness and cited adverse effects. Therefore, this …

The following are the major findings of these dissertations. The analysis of athletes by jumping ability suggested that proficient jumpers are associated with greater relative phase magnitude and phase impulse throughout the phases contained …

Relationship Between Concentric Velocity At Varying Intensity In The Back Squat Using Wireless Inertia Sensor, Kevin M. Carroll

Electronic Theses and Dissertations

The purpose of this study was to determine the relationship between the Minimal Velocity Threshold (MVT) of 1RM and repetitions until failure testing conditions using the back squat exercise. Fourteen injury-free males with experience in the back squat volunteered to perform a 1RM and a submaximal (70% 1RM) repetitions until failure test, each during different testing sessions. Mean Concentric Velocity (MCV) was collected using a wireless inertia-measuring device. The last successful repetition in either condition was considered the MVT. A very small relationship between 1RM and repetitions until failure MVT was found (r=-0.135). There were no significant differences …

The Acute Effects Of Ballistic And Non-Ballistic Concentric-Only Half-Squats On Squat Jump Performance, Timothy J. Suchomel

Electronic Theses and Dissertations

The purposes of this dissertation were to examine bilateral asymmetry as a factor of postactivation potentiation, examine and compare the acute effects of ballistic and non-ballistic concentric-only half-squats on squat jump performance, and compare the potentiation and temporal profiles of strong and weak subjects following potentiation protocols that included ballistic and non-ballistic concentric-only half-squats. The following are major findings of the dissertation. Squat jump performance may be acutely enhanced following ballistic concentriconly half-squats; however the changes in performance do not appear to be related to bilateral symmetry. Ballistic concentric-only half-squats acutely improve various squat jump performance variables at various time …

Differences In Muscle Activation While Gripping A Sandbag Versus An Olympic Weightlifting Bar 2015, Todd Luther

Master's Theses

The purpose of this study was to compare the myoelectric activity of the extensor carpi ulnaris, flexor carpi ulnaris, flexor carpi radialis, and opponens pollicis muscles while gripping a 50 lb Olympic weightlifting bar to the myoelectric activity of the same muscles while gripping a sandbag of the same weight. Myoelectric activity was measured as the average root mean square (RMS) of the surface electromyography (sEMG) values. The hypothesis was that gripping a sandbag would result in greater muscle activation of the extensor carpi ulnaris, flexor carpi ulnaris, flexor carpi radialis, and opponens pollicis muscles than gripping an Olympic weightlifting …

An Investigation Of The Relationship Between A Static Jump Protocol And Squat Strength: A Potential Protocol For Collegiate Strength And Explosive Athlete Monitoring, Cody Haun

Electronic Theses and Dissertations

The purpose of this study was to examine the relationship between estimated absolute and relative squat strength and a static jump protocol with potential to provide desirable training adaptation data to practitioners in the field of collegiate strength and conditioning. Forty-one young (20.80 ± 2.44 years), healthy volunteers reported estimated back squat 1RM’s based on the most recent training block and completed a static jump protocol. Males (n=19, est. 1RM 141.29 ± 32.02kg) and female (n=22, est. 1RM 71.56 ± 19.64kg) jump data revealed large to very large correlations between squat strength, mean jump heights of jumps and other calculated …

Stability Of Isometric Strength Asymmetry And Its Relationship To Sprint And Change-Of-Direction Performance Asymmetry In Division-I Collegiate Athletes, Benjamin H. Gleason

Electronic Theses and Dissertations

The purpose of this dissertation was to evaluate the stability of strength asymmetry over a long-term period (1 year) and investigate the relationship of strength asymmetry to field test performance asymmetry in NCAA division-1 athletes. Isometric mid-thigh pull (IMTP) peak force asymmetry, ground contact time and finish time asymmetries on 10m sprint and 505 agility test performances were also observed. The impact of strength was also investigated in these studies to determine its effect on the magnitude of asymmetry.

In the second study, peak force asymmetry over a one-year period was observed to be a rather volatile quality, with ranges …

The Impact Of Training Loads On In-Match Soccer Performance Variables: A Position-Based Case Report, Garett Bingham

The purpose of this thesis is to investigate the impact of the training load on key physical performance variables in the subsequent match. Five Division I female soccer players were analyzed across six weeks of training and matches. Training loads in the forms of odometer, high intensity odometer, estimated odometer and sRPE were accumulated at time points from one to five days prior to a match. The accumulated training …

Comparison Of External Kinetic And Kinematic Variables Between High Barbell Back Squats And Low Barbell Back Squats Across A Range Of Loads, Jacob Goodin

Electronic Theses and Dissertations

This study compared peak force, peak power, peak velocity, impulse, work, and vertical displacement between the high bar back squat (HBBS) and low bar back squat (LBBS). Six trained males performed each using 20, 30, 40, 50, 60, 70, 80, and 90% of their recent training 1 repetition maximum. Dual force plates recorded force-time curve characteristics of ground reaction forces and four potentiometers tracked vertical and horizontal barbell displacement. Repeated–measures analysis of variance revealed a significant main effect for load (p<0.01) across all variables, but no significant effects for condition or interaction. The HBBS generated higher peak force in loads 20%–80%, higher peak power in loads 20%–60% and 80%–90%, higher peak velocity at every load, and greater vertical displacement at every load. The LBBS generated a larger impulse at loads 30%-90% and the HBBS generated more work at loads 20%, 40%, and 60%–90%.

In addition, a global positioning system (GPS) watch was used to assess time to complete the trail, average speed (speed_avg), and …

The Relationships Of Physiological And Strength Variables To Run Performances, Jana Hollins

Electronic Theses and Dissertations

Monitoring progress of athletes is an essential component of the training process. Collegiate distance running coaches often use field tests to assess progress because of a lack of time and resources to do laboratory testing. The purpose of this dissertation was to examine the relationships between physiological and strength variables measured in a laboratory and field testing measures in collegiate distance runners. Collegiate distance runners completed a series of tests in the Sport Science laboratory at East Tennessee State University to obtain physiological and strength parameters, such as V̇ O2max and vertical jump height. The athletes then completed one of …

The Effect Of Protandim Supplementation On Oxidative Damage And Athletic Performance., Seteena Leigh Ueberschlag

Electronic Theses and Dissertations

A double-blind placebo-controlled trial determined the long term effects of Protandim® supplementation on 5-km running performance, as well as on acute and long-term oxidative damage assessed by serum lipid peroxides (Thiobarbituric acid-reacting substances: TBARS). Thirty-eight subjects were placed into one of two groups: an experimental (675 mg/day Protandim®) or control group (675 mg/day corn starch). 5-km runs were performed at baseline and 88 (SD 4) days post-supplementation with samples taken immediately pre- and 10-min post 5-km run, as well as at rest ∼30 and ∼60 days during the supplementation period. There was ~25% week-to-week coefficient of variation of TBARS at …

The Physics Of Human Performance: An Ideal Lab, William B. Laing Iii, Harold Mayer

Faculty Works

Physics lab goes to the gymnasium, where students calculate the mechanical power required to walk on an inclined treadmill in watts and convert to units power used to measure human performance: VO2, and METs. Students learn how to use two linear regression models: the ACSM "walking equation" to estimate the actual power expenditure of walking and the Rockport 1 mile test to estimate their own VO2max. Students use models to prescribe exercise parameters for themselves and for two cases. The IDEAL lab collaboration is developing labs that are open, applied to life, and rigorously quantitative.

Concussion Awareness And Educational Outreach Through A Website And Mobile Application, Daniel J. Brogan

Neuroscience Summer Fellows

In recent years concussions have become a more apparent problem in youth and adolescent sports. 1 in 5 high school students will sustain a concussion during the season. Due to medical and scientific advances, the diagnosis of concussions is becoming much simpler with key markers that are signs for an injury. Returning to play too soon before an athlete is fully recovered increases the likelihood that serious and irreversible neurological deficits can occur. Symptoms for concussions are necessary to track in order for an athlete to properly report their recovery to a physician. Doctors primarily rely on a patient’s report …

Impaired Executive Function In Concussed Athletes, Marisa Gretz

Neuroscience Summer Fellows

Concussions are classified as mild traumatic brain injuries (mTBI). An individual that has sustained a concussion will experience symptoms such as nausea, possible memory loss, blurry vision, or loss of balance. Most symptoms subside within a few days, but a large pool of research raises concern for the recovery of executive function, specifically impulse control. Executive function relates to all tasks that require deliberate attention. Past research has shown adolescents record the highest number of sports concussions when compared to collegiate and professional athletes. The frontal lobe, which controls executive function, is not fully developed during the time of adolescence. …

A Comparison Of Upper Extremity Function Between Female Breast Cancer Survivors And Healthy Controls: Typical Self-Report Of Function, Motion, Strength, And Muscular Endurance, Mary Insana Fisher

Mary Insana Fisher

Many women who have experienced breast cancer (BC) report continued impairments in upper extremity (UE) function beyond the time required for normal healing after surgical treatment. Most research supporting this has not made comparisons between survivors of breast cancer (BCS) to a sample of healthy women. This lack of comparison to a healthy cohort prevents an understanding of whether continued deficits in UE function are due to normal aging or the BC treatment. The purpose of this research was to compare quality of life (QOL) and UE function among long term breast cancer survivors and similar aged women without cancer. …

Understanding Stress And Aggression Behaviors Among Urban Youth, Erin E. Centeio, Laurel Whalen, Noel Kulik, Erica Thomas, Nate Mccaughtry

Kinesiology, Health and Sport Studies

Background/Objective: Youth violence, including school bullying and fighting, has become a global public health problem. Stress has been identified as a factor related to aggression (i.e., bullying behaviors, fighting, and anger), of which inner-city youth are particularly vulnerable given their often disproportionately high stress living environments. Stress and aggression are of particular concern in urban physical education (PE) given the proliferation of competitive, sport-based curricula, “culture of basketball”, and the often-limited supervision that takes place. Using the Social Ecological Model, the purpose of this study was to examine the relationships between stress and aggression in inner-city elementary PE students. …

Football Betting And The Efficient Market Hypothesis, Ravija Badarinathi, Ladd Kochman

Ladd Kochman

Three betting rules which had been nonrandomly profitable in both their initial application to the 1969-74 National Football League seasons and their replication during the years of 1975-81 were applied to all NFL games played between September 1984 and January 1994. One rule proved to be nonrandom and profitable for a third consecutive trial--a feat suggesting that bettors may be able to "beat the bookie" and, more broadly, that prices in competitive markets may not discount all available information in swift fashion.
