Chronic Training Load And Dorsiflexion Range Of Motion Throughout A Season In Professional American Soccer, Tristan L. Young
Chronic Training Load And Dorsiflexion Range Of Motion Throughout A Season In Professional American Soccer, Tristan L. Young
Electronic Theses and Dissertations
Soccer has an incredibly complex movement profile. Players experience various types of strains on their body from the requirement to land in awkward positions while maintaining the ability to quickly accelerate and decelerate. Dorsiflexion range of motion (DFROM) is of concern due to the movement profile and ball control that requires constant eccentric and concentric actions at the talocrural joint. With an American soccer season spanning across nine months these demands can contribute to overuse, which has been linked to restricted range of motion. Restricted DFROM and asymmetries have been identified as injury predictors, but their relationship to performance has …
Effects Of Occupational Tasks And Personal Protective Equipment On Static And Functional Balance Among Career Firefighters, Petra Kis
Electronic Theses and Dissertations
BACKGROUND: Musculoskeletal injuries are commonly incurred on the fireground among firefighters. Most injuries are attributable to overexertion, fall, jump, slip, and trip mechanisms. These injuries may be caused by many factors, including the independent and collective effects of wearing personal protective equipment (PPE) and the fatigue induced by performing occupational tasks. Therefore, the purpose of this study was to investigate the effect of PPE and fire suppression tasks on static and functional balance among firefighters. METHODS: 32 healthy male career structural firefighters (Age: 31.8±9.5 yr) volunteered for this study. Static and Functional Balance Tests (FBT) were performed in …
Effects Of Various Golf Bag Loading Strategies On Perceived Exertion And Vertical Jump Performance, Austen Arnold
Effects Of Various Golf Bag Loading Strategies On Perceived Exertion And Vertical Jump Performance, Austen Arnold
Electronic Theses and Dissertations
INTRODUCTION: The sport of golf is increasing in popularity among both novice and skilled players alike. A round of golf necessitates players to cope with a range of physically demanding movement patterns. At the collegiate level, golfers must transport their clubs by loading them onto the body. Previous literature has yet to determine how different golf bag carrying positions influence periodic, unloaded jump performance and perceived exertion of the load carrying task. PURPOSE: The purpose of this study is to investigate how different golf bag load carriage methods may influence vertical jump performance and perceived exertion. METHODS: Five golf bag …
The Development Of A Novel Throwing Assessment For Children With Cerebral Palsy, Cory Cribb
The Development Of A Novel Throwing Assessment For Children With Cerebral Palsy, Cory Cribb
Electronic Theses and Dissertations
Introduction: Cerebral palsy is one of childhood's most common developmental disabilities. Cerebral palsy leads to dysfunction in the upper extremities due to symptoms such as low muscle power, spasticity, and increased tone. A modified throwing assessment was constructed to examine throwing performance as a measure of upper extremity function. Purpose: To determine if the modified throwing assessment is a reliable measure of throwing performance and if the modified throwing assessment is a valid measure of upper extremity power in children with CP. Methods: The study employed a test-retest design aimed at determining the reliability of a modified throwing assessment. Seven …
The Effects Of A Mirror On Cognitive Strategy And Performance Of A Muscular Endurance Task, Brianna M. Simmons
The Effects Of A Mirror On Cognitive Strategy And Performance Of A Muscular Endurance Task, Brianna M. Simmons
Electronic Theses and Dissertations
Context: Mirrors are common-place in exercise facilities, however, the effect the mirror has on cognitive strategy (i.e., where the mind’s at) and performance time has not been examined in a muscular endurance task (i.e., a wall sit). Objective: To determine, (1) the mirror’s effect on cognitive state during a wall sit to volitional exhaustion, (2) the mirror's effect on time to volitional exhaustion during a wall sit, and (3) the mirror’s effect on the participant’s rating of perceived exertion (RPE) during the wall sit. Design: Repeated measures design. Setting: Indoor exercise facility. Participants: Twenty resistance-trained Georgia Southern University Students (9 …
Long-Term Disability Following A Hamstring Injury, Savannah Mclain
Long-Term Disability Following A Hamstring Injury, Savannah Mclain
Electronic Theses and Dissertations
PURPOSE: Injuries to the hamstring complex are one of the most commonly seen lower extremity injuries in athletic populations. It is currently unknown how psychological or sociological factors affect an athlete after the recovery process has ended and if these factors play a role in re-injury rates relating to the hamstring. It is also unknown if athlete confidence level changes while in a fatigued state after an athlete returns to play from a hamstring injury. METHODS: Twenty-six physically active adults with and without a previous hamstring injury were recruited for this study. Participants completed a Qualtrics survey that …
Current Recommendations For Lower Body Aerobic Exercise In Chronic Unilateral Stroke - A Systematic Review, Jordan N. Brown
Current Recommendations For Lower Body Aerobic Exercise In Chronic Unilateral Stroke - A Systematic Review, Jordan N. Brown
Electronic Theses and Dissertations
Background: Chronic stroke patients (i.e., > six months since the onset of stroke) continue to experience persistent gait complications. Once formal physical therapy concludes, exercise professionals can implement exercise interventions designed to improve quality of life and reduce risk of secondary stroke. This systematic review aimed to evaluate whether lower-body aerobic exercise transferred to gait improvements in chronic unilateral stroke. Methods: An electronic search of the following databases were undertaken: MEDLINE, CINHAL, Ovid, and SPORTdiscus. Two independent reviewers selected articles using predetermined inclusion criteria: adults (i.e., >18 years old) who suffered from a chronic unilateral stroke. Additionally, all included studies were …
Biomechanical Comparison Of "Old" And "New" Cheer Shoes In Collegiate Cheerleaders, Abigail C. Johnson
Biomechanical Comparison Of "Old" And "New" Cheer Shoes In Collegiate Cheerleaders, Abigail C. Johnson
Electronic Theses and Dissertations
INTRODUCTION: The sport of cheerleading requires that athletes perform with a high degree of flexibility, strength, endurance, and balance. The leading injury in cheerleading is a lateral, inversion, ankle sprain. As footwear serves as an interface between the foot and the surrounding environment, characteristics of shoes should be monitored to determine the effects on proprioceptive communication. No previous literature was found that examined the biomechanical differences between “Old” and “New” shoes in collegiate cheerleaders. PURPOSE: The purpose of this study was to examine the biomechanical differences exhibited by collegiate cheerleaders while performing balance testing and step-down, landing tasks in “old” …
Reliability Of Gastrocnemius Pennation Angle Using Ultrasound With 15 Degree Adduction And Abduction In Standing Position, Diana J. Tyler
Reliability Of Gastrocnemius Pennation Angle Using Ultrasound With 15 Degree Adduction And Abduction In Standing Position, Diana J. Tyler
Honors College Theses
A pennate muscle has fascicles that attach obliquely to its tendon. In parallel, more fascicles can be aligned allowing for greater production of force. In previous research, pennation angle has been measured using ultrasound while in a laying supine position. The purpose of this study was to measure pennation angle of the gastrocnemius muscle with ultrasound while standing neutral, in a mechanically loaded position. 16 participants, one two separate days, had their ultrasound imaging taken in three different foot orientations: neutral, fifteen degree adduction / abduction positions. This information was then be analyzed using ImageJ software. This research shows the …
