Knee Injury Prevention Program In An Early Pubertal Female Athlete During A Recreational Softball Season, Doug W. Dendy, Toby Brooks, C Roger James, Micah Lierly

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 6: Issue 1, Article 12, 2025. This case study was intended to analyze the impact of a knee injury prevention program (KIPP) for a young female athlete in a short recreational softball season. It was hypothesized that initiating a KIPP early within a recreational sports season would positively alter lower extremity biomechanics, subsequently reducing the risk of knee injuries during and after skeletal development. During a recreational softball season, a 13-year-old female athlete completed a preliminary biomechanical test, the drop vertical jump battery (DVJB_pre), underwent a 7-week in-season KIPP, then was …

Plant Vs. Animal Protein: Effect On Recovery, Performance, And Long-Term Health, Claudia Stachura

Honors Theses

Protein plays a fundamental role in muscle repair, growth, and athletic performance, which has led to increased interest in how different protein sources compare, particularly as plant-based diets become more common among athletes and physically active individuals. The debate surrounding plant-based versus animal-based protein sources primarily focuses on differences in protein quality, amino acid composition, digestibility, and potential long-term health implications. This paper examines current evidence comparing the effectiveness of plant and animal protein sources in supporting muscle protein synthesis (MPS), resistance training adaptations, recovery, and performance, while also considering broader health and environmental outcomes.

Displaced Myonuclei Are Attributable To Both Resident Myonuclear Migration And Stem Cell Fusion During Mechanical Loading In Adult Skeletal Muscle, Nathan Serrano, Pieter Jan Koopmans, Kevin A. Murach

Health, Human Performance and Recreation Faculty Publications and Presentations

Non-peripheral (displaced) myonuclei are characteristic of skeletal muscle pathology and severe injury but also appear after exercise and with aging. Displaced myonuclei are typically attributed to the activity of muscle stem cells, or satellite cells. We sought to address whether displaced myonuclei in adult skeletal muscle are exclusively from an exogenous source such as satellite cells or can result from resident myonuclear migration. To address this question, we used a murine recombination-independent muscle fibre-specific doxycycline-inducible fluorescent myonuclear labelling approach, EdU stem cell fate tracking, two durations of plantaris muscle mechanical overload (MOV, 3 days and 7 days), and fluorescent histology. …

Investigating The Cardiovascular And Autonomic Responses To Energy Drink Consumption: The Role Of Energy And Calorie Content, Sophia Schmidt

Honors Theses

Energy drinks (EDs) are among the most consumed functional beverages, often marketed to enhance focus, alertness, and physical performance. Despite their popularity, the combined cardiovascular and autonomic effects of caffeine and sugar during exercise remain poorly understood. The purpose of this study was to examine the acute cardiovascular, metabolic, and autonomic responses to sugar-sweetened (ED-S), non-nutritive sweetened (ED-NNS), and placebo beverages during submaximal cycling in healthy young males.

Nine male participants (age 22.2 ± 2.4 yrs; BMI 26.2 ± 2.9 kg/m²) completed three experimental visits in a randomized, repeated-measures design. Each visit involved ingestion of one drink (ED-S, ED-NNS, or …

Effectiveness Of Education On Increasing Training Likelihood: An Analysis In Relation To Physique Inflation, Reid J. Venable

Honors College Theses

Resistance training is a widely recommended form of exercise for enhancing muscular strength, improving metabolic health, and promoting overall quality of life. In addition to these benefits, perhaps the most popular reason for participating in resistance training is to achieve muscle hypertrophy and attain a desired or aesthetic physique. However, various factors such as the use of performance-enhancing drugs and social media have led to “physique inflation,” a cultural phenomenon in which exposure to highly enhanced or unrealistic body types shifts perceptions of what is considered a “normal” or attainable physique. As a result, many individuals avoid or delay resistance …

Host-Intrinsic Factors Determine Anti-Tumor Efficacy Of Exercise In Pancreatic Ductal Adenocarcinoma, Sumedha Pareek

Dissertations and Theses (Open Access)

Pancreatic Ductal Adenocarcinoma (PDAC) is the third leading cause of cancer-related deaths with a low 5-year relative survival rate of approximately 13.3% for all stages combined. We have previously shown that exercise can improve quality of life and enhance functional capacity among patients with PDAC. Exercise induces a variety of changes in the tumor microenvironment with beneficial effects in several tumor types. However, our understanding of the clinical effects of exercise and the mechanisms that mediate anti-tumor effects are limited in pancreatic cancer.

In this project, using C57BL/6 mice from Taconic Biosciences (Tac) and Jackson Laboratories (Jax), we established a …

The Unilateral Neuromuscular Effects Of Cross Education Eccentric-Focused Isokinetic Strength Training With Blood Flow Restriction In Sedentary And Recreationally Active Males, Bryan Mixumi

Theses and Dissertations

PURPOSE: The purpose of this study was to determine if BFR unilateral training protocols can elicit the same or greater cross-education effect as observed with HIGH protocols.

RESULTS: Significant time main effects and trained vs. untrained interactions revealed both training groups improved in isometric and isokinetic strength, work and power across limbs (P < 0.05). EMG analyses showed significant increases in vastus lateralis activation, with limb-specific neural adaptations but no group differences (P < 0.05) suggesting potential cross-education influence in the lower musculature.

CONCLUSION: With lower workloads, the BFR training protocols produced improvements in isometrics and isokinetic strength, work, power, and EMG that were comparable to those of the HIGH group across the trained and untrained limbs. The magnitude and limb-specific patterns varied across isometric, isokinetic, and EMG variables, but …

Topics in Exercise Science and Kinesiology

Topics in Exercise Science and Kinesiology Volume 6: Issue 1, Article 11, 2025. Biometric Muscle size and echo intensity are thought to influence muscle function. Unfortunately, previous works often will examine a single muscle from a group of agonists as a metric of whole muscle performance. This approach may not always be the most appropriate to assess performance outcomes. The purpose of the study was to 1) quantify the association of muscle size and echo intensity with vertical jump performance (VJ), 2) Compare the associations between individual and whole muscle group size and echo intensity, 3) determine whether single or …

A highly functional core is essential within the kinetic chain and aids in injury prevention and rehabilitation. Traditional means of core stability training are performed on a stable surface. An emerging mode of core training is suspension training (ST), which utilizes a movement paired with instability to challenge the core stabilizers and increase motor unit recruitment.The purpose of suspension training is to increase muscle activation in core stabilizer’s, while mimicking functional movements.It was the purpose of this research to …

The Impact Of Athletic Retirement On Anxiety In Elite Athletes, A Critically Appraised Topic, Jordan Gorham, Emily Madrak

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

Though there is growing interest in athletic mental health, this interest appears to diminish significantly once an athlete enters athletic retirement. The abrupt transition can precipitate mental health struggles, exacerbated by the lack of adequate preparation for lifestyle after retirement and the attachment of athletic identity to their sport. Consequently, these circumstances may increase symptoms associated with poor mental health, with a specific focus on anxiety. As the athlete retires and moves into different stages of life, research notes that athletes with stronger athletic identities have poorer mental health than those who had weaker athletic identity^. While the scrutiny …
