Evaluating The Need For Return-To-Learn Concussion Protocols In High School Student-Athletes: An Integrative Review, William David Midgette

Doctoral Dissertations and Projects

Over a million high school students are estimated to sustain at least one sports-related concussion annually. Unfortunately, over a third of these student-athletes suffer from post-concussion syndrome, which leads to the question of whether student-athletes are allowed proper time to heal after a concussion or if more can be done to optimize concussion recovery. Proper and optimal recovery post-concussion encompasses both physical and cognitive rest. While concussion management has traditionally focused on the physical aspects of recovery, emphasis has shifted to the cognitive impacts of concussions. There is literature to support that cognitive rest is vitally important, if not equally …

Health Consequences Of Low Energy Availability In Females And Their Underlying Physiological Mechanisms, Grace Parry

Senior Honors Theses

Low energy availability (LEA) is a state in which energy intake is insufficient to support energy expenditure while maintaining energy balance, which has been shown to result in gastrointestinal distress, immunosuppression, reduced metabolic rate, menstrual dysfunction, diminished bone health, and impaired cardiovascular function in females. Alterations to the microbiome and mucosal lining may propagate gastrointestinal complaints and compromised immune function associated with LEA. The pathophysiology of LEA is otherwise largely driven by hormonal adaptations. Diminished production of thyroid hormones is known to contribute to reduced metabolic rate. Decreases in leptin and insulin and increases in ghrelin disrupt reproductive function through …

A Descriptive Study On The Strike Characteristics Between A Heavy Bag, Focus Mitts, And Thai Pads, Tirzah Ruth Dacio Talampas

Masters Theses

The purpose of this study was to compare vGRFs during continuous strikes to three different modalities, a free-standing heavy bag, focus mitts, and Thai pads, and the punching velocities under these conditions. It was hypothesized for punches that punching velocity would be higher in punches thrown at a heavy bag, punching velocity would be faster in rear-hand punches, vGRFs would be higher in the lead leg compared to the rear leg of a punch at impact, and vGRFs would be higher in heavy bag punches compared to focus mitt punches. For kicks it was hypothesized that vGRFs of dominant and …

Effects Of Pre-Determined Barbell Hip Thrusting Surface Height On Motor Unit Recruitment And Activation Patterns, Abigail Renae Mccarty

Masters Theses

Several variations of the barbell hip thrust that manipulate stance width and resistance type rather than surface height to better isolate muscle groups that act as prime movers for the exercise have been previously researched. The purpose of this study was to identify the effects of hip thrusting surface heights on neuromuscular activity in the gluteus maximus (GM), vastus lateralis (VL), and biceps femoris (BF). Twelve averagely fit, resistance trained individuals were recruited for this study. Participants completed a dynamic warm-up followed by 10 repetition max (RM) testing of the barbell hip thrust. Prior to trials, root mean square (RMS) …

Effects Of Different Recovery Methods On Hangboard Performance In Rock Climbers: A Pilot Study, Daniel Tyler Ehrich

Masters Theses

The purpose of this study was to determine whether static stretching, dynamic shakes, or repeated contractions would promote the greatest retention in performance in hangboard training within a given period of time. Five volunteer intermediate climbers from the Liberty University rock climbing team were instructed to suspend themselves from a 20mm ledge on a hangboard until voluntary failure while time was recorded. After failure, subjects performed one of three different recovery methods and a control in randomized order for two minutes in alternating fifteen-second intervals. Upon finishing recovery, subjects would hang from the same ledge and have their time recorded …

The Application Of Biomechanical Technology In Sports, Timothy Leckrone

Senior Honors Theses

Technology in biomechanics encompasses eight major categories: artificial optical devices, anthropometry, timing devices, electrogoniometry, electromyography, dynamometry, inertial tracking systems, and modeling and simulation. As technology improves and becomes more accessible to the general population, it becomes easier to implement biomechanical technology into sports. For each area of focus, biomechanical technology has numerous points of current application or potential application. This application has benefit in injury prevention, technique improvement, rule enforcement, performance optimization, overall health and condition analysis, sports timing, and product development and testing. This thesis examines each area in turn as well as the various tools implemented in order …

The Role Of Hamstring Contraction During Running: An Analysis, Theodore Hu

Senior Honors Theses

The hamstring muscle group, spanning the posterior aspect of the proximal lower limb, generates large amounts of contractile force during running. Researchers have examined this power generation within different phases of the stride cycle. Forces generated by the hamstrings hold implications for both running efficiency and the role of strengthening for injury prevention. The goal of this review is to examine the hamstring’s unique physiology as a bi-articular muscle, its role in running stride, various training philosophies, and the specific impact on running economy contributing to overall running performance. The summation of research presented shows that the hamstring muscle group …

Voluntary Hypoventilation At Low Lung Volume (Vhl) During Strength And Conditioning Training Increases Anaerobic Performance: A Pilot Study, Zachary Taylor Hundley

Masters Theses

To determine whether a VHL protocol implemented into an already existing strength and conditioning program could improve anaerobic conditioning more efficiently within the military population. Six active duty males completed a seven-week training cycle with VHL protocols implemented on each training day (2-4 days/week). Before (Pre) and after (Post) protocol implementation, the participants performed a multi-stage 20-m shuttle run test (MSRT). After incorporating VHL, participants significantly improved their MRST scores by an average of 50.3%. Additionally, Body Oxygen Level Test (BOLT) scores were improved across the duration of the study. This study showed employing VHL can improve anaerobic performance in …

A Comparison Of Vertical Ground Reaction Forces In Single-Leg Jump Take-Offs And Double-Leg Jump Take-Offs In Indoor Collegiate Volleyball Players, Margaret Elisabeth Latchford, Maggie Mcdermott, Austin Deshner, Moroni De Moors, Will W. Peveler

Masters Theses

The purpose of this study was to determine if differences in vertical ground reaction forces (vGRFs) exist between single-leg take-off approaches (SL) and double-leg take-off approaches (DL) and if sex or positional differences existed in vGRFs in SL- or DL-style approaches. It was hypothesized that DL jumps would generate greater vGRFs, males would generate greater vGRFs in both styles, and middle blockers would have higher SL vGRFs while pin hitters would have higher DL vGRFs. Nine collegiate volleyball players (4 female; 5 male) (age: 20.44 ± 1.42 years; height: 186.02 ± 6.44 cm; body mass: 78.21 ± 10.63kg; body fat: …

The Impact Of Power Training On Balance And Visual Feedback Removal, Juliana Bouton

Senior Honors Theses

Because power training has been known to augment stability, the purpose of this study was to assess whether the removal of visual input affects lower limb muscle power production in young women who are resistance trained to the same degree it affects the untrained. This provided insight as far as the need for resistance training protocols in a largely untrained visually impaired population. To study this, fourteen college-aged female participants (18-23 years) performed a seated double-leg press on a leg sled machine, isolating power production of the lower limbs. After establishing baselines, which involved finding an average of power produced …

A Content Analysis Of Sports Illustrated’S Portrayal Of Female Athletes And Its Impact On Society, Britney Murray

Masters Theses

This study utilizes a content analysis of Sports Illustrated covers from 1954-2016 to evaluate the amount and type of coverage permitted to female athletes through this source of print media. The covers were critiqued for both quantity and quality as it relates to the coverage afforded to female athletes and how it differs from the coverage of male athletes. The results from this study provide a foundation for those who wish to further explore and raise awareness on the issue of underrepresentation and misrepresentation of female athletes in sports media.

Running Injuries Due To Strike Patterns, Jamie M. Rogers

The Kabod

Running is a very repetitive activity that can lead to surmountable stresses to the body over time that could lead to injury. Running biomechanics can influence the effects that the body will experience. This paper will discuss the biomechanical effects that relate to two different strike patterns: rearfoot and forefoot. Research will be examined as to how the strike patterns can influence the major lower extremity joints: ankle, knee, and hip. Common injuries during running as related to strike pattern are also discussed through conclusions based on research studies.
