A Descriptive Study On The Strike Characteristics Between A Heavy Bag, Focus Mitts, And Thai Pads, Tirzah Ruth Dacio Talampas Jun 2021

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 Jun 2021

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 May 2021

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 …


Voluntary Hypoventilation At Low Lung Volume (Vhl) During Strength And Conditioning Training Increases Anaerobic Performance: A Pilot Study, Zachary Taylor Hundley Dec 2020

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 May 2020

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: …


A Content Analysis Of Sports Illustrated’S Portrayal Of Female Athletes And Its Impact On Society, Britney Murray Jun 2018

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.


The Leadership Of John Wooden, Drew Waters Aug 2017

The Leadership Of John Wooden, Drew Waters

Masters Theses

John Wooden, former coach of the University of California, Los Angeles (UCLA) men’s basketball team, has won twice as many championships as the next most successful men’s collegiate basketball coach. This paper will examine the methods he used in his coaching, his leadership style, and how it compares with various leadership styles of other famous coaches and leaders, and other possible factors which may have led to his achieving such a high level of success. A thorough review of a wide variety of literature has been incorporated in the thesis, as well as a study comparing Wooden’s leadership style with …


Ethics With Regard To Compensation And Current Ncaa Policy, Tyler Mcbride May 2016

Ethics With Regard To Compensation And Current Ncaa Policy, Tyler Mcbride

Masters Theses

The purpose of this research is to analyze former NCAA Division I football players’ ethical perceptions of current NCAA policy, specifically concerning regulations governing compensation of the student athlete. This quantitative research study collected data using a 20-question survey instrument composed of demographic and Likert type questions. Statistical analysis determined the data failed to establish a statistically significant behavioral trend arguing either for or against current policies. However, data revealed a statistical difference between the opinions expressed by Caucasian alumni as compared to those of other ethnicities. The purpose of this study was to expose illegitimate processes within the NCAA …


The Effect Of Luck On The Retention Of Head Coaches In The Nfl, Alexander Steen Apr 2016

The Effect Of Luck On The Retention Of Head Coaches In The Nfl, Alexander Steen

Masters Theses

his investigation considers the impact of the concept of luck on coaching retention in the National Football League (NFL). The head coach of an NFL team is often under intense scrutiny to perform in a high profile position. Due to a small inventory of games each season, there is the potential for luck to influence whether or not a season is viewed a success. This study seeks to measure the impact of luck for a given NFL team while attempting to correlate with the retention or release of the head coach.
