Developing A Practical Application Of The Isometric Squat And Surface Electromyography, David Phillips, Angelic Rose Del Vecchio, Kevin Carroll, Evan L. Matthews

Department of Exercise Science and Physical Education Scholarship and Creative Works

Electromyography (EMG) is a research tool used in gait analysis, muscle coordination evaluation, clinical evaluation and sports techniques. Electromyography can provide an insight into neural adaptations, cross education effects, bilateral contraction deficiencies, and antagonist activity in exercise-related movements. While there are clear benefits to using EMG in exercise-related professions, accessibility, cost, and difficulty interpreting the data limit its use in strength and clinical settings. We propose a practical EMG assessment using the isometric squat to identify compensatory activation patterns and report early observations. Ten healthy participants were recruited. Participants performed a 2-min isometric handgrip protocol and an isometric squat protocol. …

Acute Physiological And Perceptual Responses To Unilateral Versus Bilateral Walking With Blood Flow Restriction, Sage Donaldson

Honors Theses

The use of blood flow restriction (BFR) has skyrocketed in popularity in the past few years as a therapeutic modality. Studies have shown that the application of BFR at 20-30% of maximal oxygen consumption (VO_2max) yields similar improvements in cardiovascular fitness, muscle mass, and strength when compared with traditional exercise at 60-90% of VO_2max. The substantially lower workload accompanying BFR allows for more tolerable workloads in special populations, such as those recovering from musculoskeletal injury. Because previous studies regarding BFR have mainly focused on bilateral BFR, it is unclear how unilateral BFR compares to bilateral BFR. …

From Professor To Patient X, Anne R. Crecelius

Health and Sport Science Faculty Publications

I walked into the classroom feeling nervous. It wasn't my first time teaching undergraduate students about human endocrine physiology. I knew the material well. But today's lecture was different. I pulled up slides depicting a hypothetical cancer patient and told them, “Patient X had a biopsy that detected invasive carcinoma in her breast.” I described the many months of chemotherapy, surgery, and radiation treatments she went through before going into remission. Then I taught the students about the hormonal therapy she was prescribed—drugs her doctor hoped would limit the growth of any remaining cancer cells and prevent a recurrence. On …

Menstrual Dysfunction As The Leading Clinical Marker For The Future Development Of The Female Athlete Triad: A Meta-Analysis, Sydney Hotz

Health and Kinesiology Theses

The Female Athlete Triad is a diagnosable medical condition that is under researched and very prevalent in female sports today. The development of the Female Athlete Triad, or any of its components, can negatively impact many aspects of a female athlete’s life. If clinical markers could be identified that indicate future development of the Triad, it could potentially help prevent occurrence of the condition and greatly reduce the number of female’s that have to suffer from it. Menstrual dysfunction could be the leading clinical marker for the future development of the Triad. This meta-analysis seeks to explore the possible association …

Regression Analysis Of Pacing When Running A Marathon, Hawkin Starke

Industrial Engineering Undergraduate Honors Theses

Regression analysis can be an effective way of examining performance in the marathon event. By splitting up the race into segments or in runner terminology “splits” the significance of each segment as it relates to the total finish time can be explored. Because the idea of splits is already ingrained into the minds of runners, it makes intuitive sense to use these as the metrics to define a race. Additionally, marathons generally make participant age and gender date publicly available which can then be used to find trends within specific demographics. This tailors trends to smaller groups of people, making …

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) …

Many of these disparities are nutrition-related, as the health issues that most disproportionately affect the Latinx population are obesity and diabetes. In order to treat these dietary-related health disparities, one must examine the complex aggregation of factors that work to influence specific dietary habits. Dietary habits are impacted by a series of individual, social and environmental factors. Moreover, in the case of Latinx nutrition, the level of acculturation, or cultural adjustment, plays a crucial role in …

The Physiological Effects Of Therapy Dogs During Exercise For Sedentary Adults, Josie Lynne Mazzone

All NMU Master's Theses

Previous research has shown therapy dogs may be utilized to attenuate heart rate (HR) and blood pressure (BP) responses during various types of stressors due to an increase in oxytocin (OT) and decrease in cortisol (CL) production. These hormonal changes have also been shown to enhance exercise performance. Purpose: This study aimed to determine if physiological responses to exercise changed in the presence of a therapy dog for sedentary adults. Methods: Seven adult subjects (mean age of 30.86 ± 14.07 years) who self-reported less than 150 min of physical activity per week participated in a graded walking test with a …

Agreement Level Of Running Temporal Measurements, Kinetics, And Force-Time Curves Calculated From Inertial Measurement Units, Austin Smith

Electronic Theses and Dissertations

Inertial measurement units (IMUs) and wearable sensors have enabled athlete monitoring and research to become more ecologically valid due to their small size and low cost. IMUs and accelerometers that are placed on the body close to the point of impact and that record at sufficiently high frequencies have demonstrated the highest validity when measuring temporal gait event moments such as ground contact time (GCT) and flight time (FT) as well as peak forces (PF) during upright running. While the use of IMUs has increased in the sport performance and athlete monitoring realm, the potential of the technology’s ability to …

Improving The Specificity Of Vertical Stiffness Measurement In Depth Jump Landings, Miles Mercer

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Greater lower extremity stiffness has been shown to increase bilateral jump height through stretch-shortening cycle optimization. Currently, there are two established methods for estimating vertical stiffness (K_vert) of the human body, which is a variant of lower extremity stiffness. The validity of these methods for estimating K_vert in non-cyclical human movements has been questioned recently due to the complex physiological and neuromotor factors that support stiffness regulation in the muscle-tendon complex. The purpose of the present study was to improve the specificity of K_vert measurement using direct derivation of vertical ground reaction force (GRF) and center …

Effects Of Carbohydrate Mouth Rinsing Plus Ingestion On Cycling Time Trial Performance, Henry D. Gebhardt

Electronic Theses and Dissertations

Due to limited glycogen stores, carbohydrate (CHO) consumption during exercise is effective at improving performance in endurance events lasting longer than 90 minutes in duration. Recent research has established that CHO mouth rinsing may improve performance over shorter durations, independent of actual consumption. However, research is lacking in determining if an extended period of mouth rinsing has any additive benefit in conjunction with typical CHO beverage consumption over longer competition durations, where CHO ingestion/consumption is likely warranted. PURPOSE: Determine the effects of CHO mouth rinsing combined with consumption compared to CHO consumption alone on cycling performance. METHODS: Following …
