Assessment Of Motivation In Human Anatomy And Physiology Students, Mary Whitehead

Honors Theses

Motivation is the key to success in difficult science courses such as Human Anatomy and Physiology. Students may possess intrinsic motivation, or motivation for enjoyment, extrinsic motivation, or motivation for a reward, or amotivation, a lack of motivation at all. The goal of this experiment was to identify better ways of helping students succeed in Human Anatomy and Physiology (HAP) at the University of Mississippi, determine when motivational efforts seem to decrease during the semester, and identify how to better develop intrinsic motivation in students. There was a significant relationship between many of the student’s survey responses to their exam …

Assessment Of Spatial Skills In Human Anatomy And Physiology Students, Abigail Carroll

Honors Theses

Visual spatial skills are an individual’s ability to mentally and manipulate the shapes, forms and positions of objects. Spatial skills are necessary for adequate learning in many settings. Few studies have assessed spatial skills compared to success in Anatomy and Physiology in undergraduate students. Most students in this course are on a health profession track. Due to the increasing health care demands and need for competent health care professionals, this study assesses the innate spatial skill ability in students and acquired additional learned spatial skills. This study tests 17 students with the paper-folding test, blank page test, and two surveys …

The Effects Of Acute Beetroot Juice Ingestion On Upper And Lower Body Muscular Power During Weightlifting Exercise In Men, Grant Weiderman, Chandler Riley, Joanna Powell, Katie Price, Lauren Wideen, Andrew Fest, Justin Kim, Maya Hammer, Sean Karl, Isabella Lincoln, Noelle Seekamp-Hicks, Joshua Leow, Maddy Espinoza, Adam Pennell, Rachel Tan

Seaver College Research And Scholarly Achievement Symposium

Nitrate-rich beetroot juice (BR) supplementation improves movements with high-velocity and high-power muscle contractions which may be due to enhanced blood flow, oxygenation and contractile function in type II muscle fibers. The literature has focused predominantly on the effects of BR supplementation running and cycling performance, but its efficacy in resistance exercise, a modality that relies on type II muscle fibers, has limited data. Furthermore, it is unknown how supplementation strategies impact the physiological and ergogenic effects of BR during exercise. Therefore, the purpose of this study is to assess whether single or multi-day nitrate ingestion will improve performance and muscle …

Pomegranate Extract Supplementation On Neuromuscular Performance During Resistance Exercise, Katie Price, Joanna Powell, Matthew Joyner, Adam Pennell, Rachel Tan

Seaver College Research And Scholarly Achievement Symposium

Dietary nitrate supplementation has been shown to improve skeletal muscle function during high-velocity and high-power contractions due to its high nitrate levels; however, there is limited data examining its potential in exercise requiring these movements, such as resistance exercise. Nitrate supplementation has been studied extensively as beetroot juice, but its poor taste severely limits its application. Pomegranate extract (POM) may be an alternative nitrate source due to its superior taste, high nitrate content, and additional antioxidants but has yet to be explored. The purpose of the present study is two-fold: 1) to determine the nitrate concentration in POM; and 2) …

The study aim was to evaluate the effect of a 6-week modified workout routine using the modified circuit weight method on selected anthropometric measures, components of physical fitness and physiological indices in competitive basketball players. The study involved 30 basketball players (mean age: 23.4 ±1.8 years). Modified circuit weight method sessions were repeated 3 times a week. Each training session was subdivided into 3 circuits: strength conditioning, exercises to enhance functional fitness and a circuit of sport-specific exercises. Statistically significant differences in values of circumferences and skinfolds were found between pre-test and post-test values, with no statistically significant changes in …

Impact Of Menstrual Phases On Stress Markers: A Pilot Study, Bailey C. Weishaar, Hunter S. Waldman, Kyle T. Patek, Matthew J. Mcallister

International Journal of Exercise Science: Conference Proceedings

PURPOSE: Previous research has shown that different phases of the menstrual cycle may impact biometrics such as markers of stress and inflammation [e.g., cortisol (CORT), interleukin-6] as well as body composition. However, there is scarce literature regarding markers of stress and oxidative stress such as salivary a-amylase (sAA), immunoglobin-A (SIgA) and uric acid (UA), in relation to the four different menstrual phases. The purpose of this study was to examine the impact of menstrual phases on sAA, CORT, UA and SIgA. METHODS: 21 pre-menopausal women with regular menstrual cycles (n=9) oral contraceptive users (OC) and ( …

Calpain-Mediated Protein Targets In Cardiac Mitochondria Following Ischemia–Reperfusion, Ling Li, Jeremy Thompson, Ying Hu, Edward J. Lesnefsky, Belinda Willard, Qun Chen

Internal Medicine Publications

Calpain 1 and 2 (CPN1/2) are calcium-dependent cysteine proteases that exist in cytosol and mitochondria. Pharmacologic inhibition of CPN1/2 decreases cardiac injury during ischemia (ISC)–reperfusion (REP) by improving mitochondrial function. However, the protein targets of CPN1/2 activation during ISC–REP are unclear. CPN1/2 include a large subunit and a small regulatory subunit 1 (CPNS1). Genetic deletion of CPNS1 eliminates the activities of both CPN1 and CPN2. Conditional cardiomyocyte specific CPNS1 deletion mice were used in the present study to clarify the role of CPN1/2 activation in mitochondrial damage during ISC–REP with an emphasis on identifying the potential protein targets of CPN1/2. …

Pulmonary Capillary Recruitment And Distention In Mammalian Lungs: Species Similarities, David Langleben, Benjamin D. Fox, Stylianos E. Orfanos, Michele Giovinazzo, John D. Catravas

Bioelectrics Publications

Pulmonary arterial pressure rises minimally during exercise. The pulmonary microcirculation accommodates increasing blood flow via recruitment of pulmonary capillaries and, at higher flows, by distention of already perfused capillaries. The flow transition range between recruitment and distention has not been studied or compared across mammalian species, including humans. We hypothesised that the range would be similar. Functional pulmonary capillary surface area (FCSA) can be estimated using validated metabolic techniques. We reviewed data from previous studies in three mammalian species (perfused rabbit lungs and dog lung lobes, and exercising humans) and generated blood flow-FCSA curves over a range of flows. We …

Pre-Season Body Composition Has Minimal Influence On In-Season Match Availability, And Match Performance In Female Australian Football League (Aflw) Players, Callum J. Mccaskie, Marc Sim, Robert U. Newton, Jarryd Heasman, Brent Rogalski, Nicolas H. Hart

Research outputs 2022 to 2026

This study examined the relationship between pre-season body composition, in-season match performance, and match availability in female players competing in the Australian Football League Women's (AFLW) competition. With the outlawing of body composition assessments as part of pre-draft player evaluations in the AFLW, this study seeks to examine whether this is justified. Twenty-two (n = 22) players had body composition assessed with dual-energy x-ray absorptiometry at the beginning of the 2021 AFLW pre-season (whole-body and regional fat mass and lean soft-tissue mass [LSTM]). In-season match availability and match performance data (Coaches Score [CS], Champion Data Player Rank, average disposals, disposal …
