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 …

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 …

Narrative Inquiry: Life Experiences Of Elite Athletes, Sarah Elizabeth Brown

Graduate Theses and Dissertations

Elite athletes face numerous personal and professional pressures and high-stress experiences; however, there is a gap in the literature connecting identity development with these life experiences. Using narrative inquiry analysis with six emerging adult athletes competing at professional and Olympic levels, this study identified self-narratives they created from life experiences within the context of sport and analyzed when these meanings were formed. Athletes described experiences causing great psychological disturbances as a normal risk within their sport and needing to regulate or compartmentalize their emotions to get through those experiences. Participants discussed various roles they play within their team but lacked …

Sex-Based Differences In Acvr2b And Grb10 Expression In Skeletal Muscle During Induced Cancer Cachexia And Disuse, Lauren Martinez

Graduate Theses and Dissertations

Background: Muscle atrophy is the shrinkage of muscle fibers that are largely maintained by a balance of protein synthesis and degradation. Imbalances in protein synthesis and degradation are observed in different muscle atrophy disorders such as cancer cachexia and disuse. These forms of muscle atrophy produce distinct wasting pathologies that are influenced by biological sex. Activin receptor type-2B (ACVR2B) and Growth factor receptor-bound protein 10 (GRB10) have been identified as genes that potentially regulate muscle mass while also displaying sexually dimorphic differences. Purpose: To examine the influence of ACVR2B and GRB10 throughout the development of cancer cachexia and disuse-induced atrophy …

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 …
