Kettlebell Swings As A Conditioning Activity On Standing Power Throw: Exploring Post-Activation Performance Enhancement In Rotc Cadets, Knik Durman

Masters Theses & Specialist Projects

Post-activation performance enhancement (PAPE) is a neuromuscular phenomenon where high-intensity conditioning activities (CA) temporarily improve explosive performance. While resistance and ballistic exercises are well-studied for PAPE, the effectiveness of kettlebell swings (KBS) in enhancing Standing Power Throw (SPT) performance remains unclear. Given the SPT’s role in the Army Combat Fitness Test (ACFT), identifying effective PAPE strategies could improve ACFT scores. Using a randomized crossover design, this study examined whether KBS before the SPT enhanced throw distance in 19 ROTC cadets (male: n = 17, female: n = 2). Participants completed two conditions: (1) KBS (two sets of five reps with …

Menstrual Cycle Variations In Ultrasound And Biomechanical Risk Factors For Acl Injury In Adolescent Female Athletes, Jessica Garcia

Kinesiology Dissertations - Archive

Anterior cruciate ligament (ACL) injuries are a significant concern in adolescent female athletes, with rates consistently higher than their male peers. This disparity is attributed to a complex combination of anatomical, hormonal, and neuromuscular factors that elevate injury risk while performing dynamic movements common in running and cutting sports such as soccer, basketball, lacrosse, and volleyball. Knee laxity has been identified as a potential risk factor, yet current measurement tools lack the sensitivity, reliability, and validity needed for practical application. Additionally, fluctuating sex hormones throughout the menstrual cycle (MC) have been implicated in changes to ligament properties and neuromuscular control, …

The Effects Of Shoe Forefoot Design On Center Of Pressure And Knee Moments During Running In A Fatigued And Non-Fatigued State, Tyler Tran

Open Access Master's Theses

Runners experience high injury prevalence, which can be attributed to the overloading of the musculoskeletal system during the repetitive motion of running (Kakouris et al. 2021, Lopes et al. 2012). While some running mechanics are associated with better performance or increased risk for developing an orthopedic condition, many are still poorly understood (Van Hooren et al. 2024, Willwacher et al. 2022). Center of pressure and frontal plane knee moments are two such mechanics with a limited body of evidence leading to its importance (Mehdizadeh et al 2021, Baker et al. 2018). Although running mechanics describe the motion, the origin of …


Innovative Biomechanical And Engineering-Based Assessments Of Hip Mechanics In Individuals With Hip-Related Pain, Holly M. Stanze Jan 2025

Innovative Biomechanical And Engineering-Based Assessments Of Hip Mechanics In Individuals With Hip-Related Pain, Holly M. Stanze

Theses and Dissertations--Kinesiology and Health Promotion

Individuals with hip-related pain exhibit altered movement patterns, and worse fear of movement (kinesiophobia), compared to asymptomatic controls. Exacerbation of hip pain during movement and the role of hip symptom duration may help further our understanding of specific movement patterns that are associated with hip-related pain. A better understanding of the potential connections between hip-related symptom duration, kinesiophobia, hip pain during movement, and lower limb mechanics in those with hip-related pain may allow for more efficient referrals to clinicians and lead to more effective rehabilitation. In addition, the impact of hip-related pain on intra-articular hip loading patterns is not well …

Using Accelerometry To Determine Loss Of Active Eccentric Control During The Nordic Hamstring Exercise, Makenna Kulzer

College of Graduate Studies: Theses & Dissertations

Hamstring strain injuries are among the most common musculoskeletal injuries in sports with high recurrence rates. The Nordic hamstring exercise (NHE) is a commonly used eccentric exercise intervention to reduce injury risk but has generated controversy regarding its utility due to limited sport specificity. Research examining how NHE performance affects its efficacy remains scarce. Therefore, this study investigated whether accelerometry data could describe the loss of active eccentric control (Q2) and if there is an interaction between leg preference and repetition on time to Q2. METHODS: Thirty college-aged students with >3 months of resistance training experience (1-2x/week). were recruited. Participants …


Computational Approaches For Diagnosing Neurological Impairments And Restoring Functional Movement, Serhii Bahdasariants Jan 2025

Computational Approaches For Diagnosing Neurological Impairments And Restoring Functional Movement, Serhii Bahdasariants

Graduate Theses, Dissertations, and Problem Reports (ETD)

Movement is the primary means by which the nervous system converts intention into interaction with the environment. Voluntary limb motion enables standing, walking, reaching, and grasping—actions that underpin self‑care, communication, and economic participation. When diseases or injuries disrupt the pathways that couple neural commands to muscle forces—whether through cortical stroke, spinal cord injury, or peripheral nerve damage—mechanical outcomes such as weakness, loss of coordination, and ultimately reduced mobility emerge. These impairments cascade into secondary complications, increased dependence on caregivers, and diminished quality of life. Quantifying how the lesion alters the mechanics of movement is therefore essential for designing targeted interventions …
