Swimmers’ Upper Trapezius Activation During Shoulder Abduction Compared To Non-Overhead Athletes, Kendra Graham

Senior Honors Projects

Overhead sports such as baseball, tennis, volleyball, softball and swimming are known to cause rotator cuff imbalances and injuries. These injuries are typically caused by the repeated use of “throwing motion,” where the humerus is externally rotated and shoulder abducted and elevated. Previous research has shown that the function of the upper trapezius muscle in overhead athletes is likely to have improper activation (timing, magnitude) during various shoulder motions and/or activities of daily living. Swimmers are especially susceptible to this improper activation due to the use of their upper limbs in a repeated throwing motion. The added resistance of the …

The Association Between Bilateral Broad Jump Performance And The Sprint Profile, Sergio Alfonso Rodriguez

Open Access Theses & Dissertations

Horizontal force application is vital to attain high velocities during sprinting. Similarly, broad jump performance is associated with the application of horizontal force to achieve greater jump distance. The video analysis-based sprint profile provides insight into multiple measures of sprint performance including maximal theoretical horizontal force, maximal theoretical velocity, optimal velocity, and maximal speed, which give an indication of overall sprint performance that is not reliant on spatiotemporal data alone. PURPOSE: To determine the relationship between broad jump distance and power output and the sprint profile of Division I track and field athletes. METHODS: This study was conducted as a …

Relationship Between Global Cognition And Cardiovascular Risk Factors, Alexia Sebghati

Health, Human Performance and Recreation Undergraduate Honors Theses

Alzheimer’s disease (AD) is currently affecting the lives of 5.8 million Americans and is expected to double within the next 30 years. With an aging populace of baby boomers, this will place great economic strain on the U.S. creating a burden of almost $1 trillion in healthcare costs. Currently, there is no cure for AD. However, studies report that many individuals with AD experience changes in the brain up to 10-15 years before the disease’s onset. It is imperative to detect future risk of developing AD or mild cognitive impairment (MCI) before significant cognitive changes arise. Many of the risk …

The Effects Of A Loaded Pre-Competition Activity Using Tethered Swimming On 25-Yard Swim Sprint Performance 2021, Jacob Burchfield

Master's Theses

Warmup is a standard practice for swim competitions, but there is minimal scientific evidence regarding the effectiveness of pre-competition activities (PCA) after the swim warmup. This study examined whether a loaded PCA using tethered swimming while attached to a power rack improves performance in a 25-yard swim sprint. Post activation performance enhancement (PAPE) may be the proposed mechanism for improvement resulting from a loaded PCA. To determine if PAPE existed following the loaded PCA, varsity swimmers from SUNY Cortland performed a 25-yard sprint a loaded PCA and after an unloaded PCA (control). All participants performed a standard meet warmup (1600-yards) …

Effects Of High Intensity Interval Training On Cardiorespiratory Fitness And Body Composition In Women: A Review, Rachel Marie Dykstra

Dissertations

Background: A growing body of literature indicates that women, in comparison to men, report significantly more barriers to exercise, often times related to perceived lack of time due to their social roles (e.g. family responsibility, childcare). Therefore, it has been considered that exercise programs that require less time commitments would be more attractive for women to alleviate this concern. Objective: This review was conducted to comprehensively understand the present literature surrounding women and such a time-efficient protocol: high intensity interval training (HIIT). The primary aim was to determine the impact of HIIT on both cardiorespiratory fitness (CRF) and body composition. …

Effects Of Different Stretching Modalities On The Antagonist And Agonist Muscles On Isokinetic Strength And Vertical Jump Performance, Samuel Montalvo

Open Access Theses & Dissertations

Warm-ups are essential components of all training sessions, sports, and physical activities. Warm-ups are typically composed of a variety of stretches. Two stretching modalities that are commonly performed before any physical activity are the static and dynamic stretching modalities. Historically, static stretching has been used as a preferred stretching modality during the warm-up period. However, research indicates that static stretching â?? if done prior to the training session â?? may inhibit the expression of muscular strength, muscular activation, and vertical jump height. On the contrary, dynamic stretching has been shown to improve the expression of muscular strength, muscular activation, and …

The Effects Of A Combined Multi-Stressor Environment And Fatigue On Pistol Shooting Performance, Owen Frederick Salmon

Open Access Theses & Dissertations

Acute cold and hypoxia exposure are common environmental stressors to military personnel and can influence human performance (marksmanship, exercise capacity, and strength) in a variety of different ways. Despite both cold and hypoxia being potent independent environmental stressors, both of these environmental stressors commonly coexist in nature and are rarely studied together. It is currently unclear how combined exposure to acute cold and hypoxia will influence pistol shooting performance. Therefore, the present study aimed to determine how combined exposure to a multi-stressor environment will influence pistol shooting performance independently, and in combination with environmental exposure and exercise-induced fatigue. Six subjects …

Sprint Kinematic Performance Changes Upon Returning From A Declining Period In Track And Field Sprinters, Joshua Del Rio

Open Access Theses & Dissertations

Sprinting is a key component of many competitive sports. Coaches regularly seek ways to improve their athletes’ sprint performance in order to improve their sports game performance. Sprinting is a complex movement pattern that has many different subcomponents to be properly trained in order to become faster. A sprint event has three major phases (acceleration, maximum velocity/constant speed, and deceleration). Coaches are constantly looking to improve their athlete’s performance. This is done by a strategic training regimen that extends throughout the entire year. During the off-season, the coaches’ main focus is to maintain conditioning and performance adaptions. Previous studies have …

In the current study, which is a multisite collaboration with the physical therapy programs at the University of Connecticut and the University of Delaware, we are assessing the effects of two types of movement-based interventions compared to a standard-of-care seated play control intervention on motor performance in children with ASD. This thesis will analyze data from one of the movement training groups, i.e., the play group, that involved children engaging in activities based on music, dance, and …

Implementation Evaluation Of Blood Flow Restriction In The Clinical Setting, Madison Mccall

Honors Theses

Blood flow restriction (BFR) refers to a relatively new training/rehabilitation method consisting of a tourniquet system applied to a limb to partially inhibit blood flow to the muscles distal to the tourniquet. Though much research has been conducted concerning its use, there is little information addressing why clinicians may or may not implement it. Diffusion of Innovation (DOI) theory explains how a product or idea can spread to specific population groups, ending in adoption of it. The Consolidated Framework for Implementation Research (CFIR) consists of a set of constructs which can be used to determine the specific factors involved in …

The Influence Of Sports-Related Concussion On Lower Extremity Injury Risk In Adolescent And Collegiate Athletes, Jason M. Avedesian

UNLV Theses, Dissertations, Professional Papers, and Capstones

Sports-related concussion (SRC) represents a major epidemiological concern in the adolescent and collegiate athlete populations, with conservative estimates of approximately four million SRCs occurring each year in the United States. While the majority of previous research has emphasized the management and recovery of the cognitive aspects of SRC, recent data indicates subtle motor behavior is altered following a concussive event. Injury surveillance literature indicates that adolescent and collegiate athletes are at an approximately 2–4 greater risk for lower extremity (LE) injury following an SRC when compared to matched controls and pre-SRC LE injury rates. Furthermore, athletes with a previous SRC …

Investigation Of Algorithms To Assess Validity Of Wearable Technology During Field Testing, Brenna Barrios

UNLV Theses, Dissertations, Professional Papers, and Capstones

Wearable technology is an emerging fitness trend where the technology which supports it lacks validity verification. Furthermore, heart rate validity of these devices vary greatly when observed in laboratory settings vs. field testing. Secondarily, Consumer Technology Association guidelines require a minimum five minute trial for wearable testing. This study examined heart rate data of previously tested wearable devices (Garmin Fenix 5, Jabra Elite Sport, Motiv Ring, Scosche Rhythm+) in an outdoor setting to further understand their performance, and to examine the relationship of the five minute regulation. Two separate algorithms were applied to the original data set, the first shortened …
