The Impact Of Heavy Resistance Training On Type Ii Muscle Fibers Throughout Female Reproductive Stages, Lily G. Colberg

Scripps Senior Theses

Type II muscle fibers, also known as fast-twitch muscle fibers, are reliant on aerobic glycolysis and are crucial for high-force contractions, mobility, and rapid movements, such as fast reflexes. Heavy resistance training has been found to increase type II muscle fiber concentration in young, middle-aged, and elderly individuals. However, there have been few studies conducted on female-only sample populations. In women, the impact of heavy resistance training on type II muscle fibers is affected by the progressive decline of estrogen that defines the transition throughout the four female reproductive stages: premenopause, perimenopause, late-transition menopause, and postmenopause. Menopausal estrogen depletion causes …

Anterior Cruciate Ligament Injury Resilience In Women's Lacrosse: An Ecological Dynamics Approach, Annika J. Wozney

Senior Honors Theses and Projects

Anterior cruciate ligament (ACL) injuries remain a significant concern in the sport of women’s lacrosse due to the amount of cutting and rapid deceleration movements in the sport. Non-contact ACL injuries in women’s lacrosse arise from complex interactions involving biomechanical, anatomical, and neuromuscular factors. Traditional ACL injury prevention programs (IPPs) often focus on strengthening and neuromuscular training in controlled environments with pre-planned movements, which may not adequately simulate the cognitive demands and unpredictability during a competition. An ecological dynamics approach is proposed that considers the athlete, the game environment, and the immediate task to emphasize the athlete-environment relationship. By incorporating …

The Role Of Resistance Training In Modifying Cardiovascular Diseases And Diabetes, Mikayla P. Rucinski

Senior Honors Theses and Projects

This review of literature examines the role of resistance training as an effective intervention for modifying risk factors associated with cardiovascular diseases and diabetes. Evidence from clinical and exercise interventions indicates that resistance training improves glycemic control by increasing lean muscle mass, enhancing insulin sensitivity, and facilitating greater glucose uptake in individuals with diabetes. In addition, resistance training has been shown to reduce resting blood pressure, improve lipid profiles, enhance vascular function, and decrease fat mass. Collectively, these physiological adaptations contribute to lowering the development and progression of cardiovascular disease across various populations. The findings support resistance training as an …

Should More Teams "Trust The Process" Of Tanking?, Eduardo G. Minuci, Alexander Cardazzi, Candon Johnson

Economics Faculty Publications

In many professional sport leagues, the worst-performing teams receive higher probability of earning top draft picks. This provides teams incentives to purposefully lose, or "tank," if they are not likely to contend for the playoffs or championships. We evaluate the effectiveness of tanking to improve team outcomes by examining the most explicit tanking case in the NBA: the "Trust the Process" Philadelphia 76ers. Using synthetic control, we demonstrate that tanking caused the 76ers to be more successful in terms of winning and operating income. However, only operating income had a plausibly positive present value when calculating discounted present values.

Increasing Occupational Therapy’S Visibility In College Sports Medicine In Student-Athletes With Season-Ending Injuries, Mickaela H. Buzzy, Bonnie Fischer-Camara

Post Professional Occupational Therapy Doctoral (PPOTD) Student Capstone Projects

Sport is an essential part of a student-athlete’s life. Many student-athletes gain a strong “athletic identity” in their sport. When a student-athlete is faced with an injury, specifically a season-ending injury, they are at risk of facing a significant sense of loss of identity and adverse psychological effects on their mental health. In the collegiate athletic setting, athletic trainers are often the first to notice signs of psychological distress of student-athletes; however, they frequently report limited education, training, and confidence in providing necessary psychosocial interventions. The purpose of this capstone project was to increase occupational therapy’s visibility in the collegiate …

Acute Changes In Muscle Thickness And Perceptual Responses Following Different Applications Of Blood Flow Restriction, Anuj J. Prajapati

Honors Undergraduate Theses

The use of blood flow restriction (BFR) allows for reductions in exercise intensity without compromising muscular adaptations that are typically only manifested during high-load non-BFR exercise. There exist, however, several ways to implement BFR and there is a lack of information regarding which application may be beneficial over another. The purpose of this investigation was to examine acute changes in muscle size and perceptual responses following different pressure applications of BFR (i.e., continuous BFR [cBFR], intermittent during sets BFR [iBFR_sets], and intermittent during rest BFR [iBFR_rest]) relative to an unrestricted condition (i.e., nBFR). Participants completed cBFR, …

Relationships Between Quadriceps Neuromuscular Function And Time From Surgery Following Acl Reconstruction Are Sex-Specific, Tatiana Restrepo

Honors Undergraduate Theses

Anterior cruciate ligament reconstruction (ACLR) is associated with persistent quadriceps dysfunction, including muscular weakness and altered spinal and cortical excitability. While recovery has been widely studied, most investigations focus on isolated domains and fixed postoperative time points. Emerging evidence suggests females often experience slower or less complete quadriceps recovery compared to males, yet the time-dependent nature of these sex-specific outcomes remains unclear. The purpose of this study is to examine whether relationships between time since ACLR and quadriceps neuromuscular outcomes differ by sex across muscular, spinal, and cortical domains. Adults aged 18–35 with a history of primary, unilateral ACLR were …

Stability Of Salivary Microrna Measures Across An Ncaa Division I Football Season: Implications For Microrna As A Biomarker Of Concussion, Thomas R. Campbell, Martina Zamponi, Delaney Leathers, Julie Cavallario, Jessica C. Martinez, Peter A. Mollica

Rehabilitation Sciences Faculty Publications

Background

Clinicians often face challenges in concussion care due to a heavy reliance on subjective patient input. Recently, research has sought objective biomarkers, like salivary microRNAs, to improve concussion management. However, significant limitations hinder the use of microRNAs as a diagnostic tool, including the cumulative effects of a contact sport season. A better understanding of the response to a contact sport season would help researchers and clinicians interpret expression changes at the time of injury in the context of seasonal variation. in Therefore, this study investigated the reliability of previously identified salivary microRNA targets across one contact sport season.

Effects Of The Menstrual Cycle Phase On Rpe, And Symptom Characteristics In Pre-Professional Female Soccer Players, Emily Potts

College of Graduate Studies: Theses & Dissertations

Hormonal fluctuations across the distinct phases of the menstrual cycle have been shown to influence physiological and psychological responses to exercise, with some evidence suggesting phase-dependent changes in symptom presentation and ratings of perceived exertion (RPE); however, findings remain inconsistent, and few studies have examined these relationships across an entire competitive season in female soccer players. The purpose of this study was to examine changes in RPE and menstrual symptoms across cycle phases, as well as the relationships between RPE and symptom reporting in pre-professional female soccer players. A total of 22 female soccer players (age 22± 1.85) were recruited …

Assessment Of Countermovement Jump In Athlete Status And Monitoring, Michael David Delong

Graduate Theses, Dissertations, and Problem Reports (ETD)

Utilizing a CMJ to test athlete physical abilities and training program efficacy is popular, as it is simple, noninvasive, and has significant relations with sport qualities. However, assessments often use discrete outcome measures. This research explored strategy-based measures accounting for eccentric power and time and may explain athlete status more effectively. The research objectives are to analyze the use of the mean power rate of the CMJ to compare athletes' playing ability and its usefulness in monitoring during off-season training. Additionally, power-time curve analysis added location and timing of effects due to fatigue or fitness adaptation. Proper testing and monitoring …

Test-Retest Reliability And Validity Of The Gas Exchange Threshold, Erik Ryan Snell Mr.

Theses and Dissertations--Kinesiology and Health Promotion

Theoretically, the gas exchange threshold (GET) demarcates the moderate and heavy intensity domains, whereby exercise performed at and below the GET results in a change in oxygen consumption ([ΔVO₂] ≤ 200 mL), and exercise above the GET results in a slow component (ΔVO₂ > 200 mL). This study examined the reliability and validity of the GET. 14 subjects performed two maximal graded exercise tests (GXTs) to determine the GET and its reliability. The minimal difference (MD = 21W) was applied to determine the GET above (GET_+MD) and below (GET_-MD) power outputs for 30 min …
