The Effect Of Loaded Backpack Usage On Balance After A Functional Daily Stair Task, Shanni Moorse, Alyssa Haus, Seth A. Paradis

Applied Health Sciences Student Works

Backpack usage is common among many age groups, including college students. As students go about their daily routines, they may reach cardiorespiratory fatigue (CRF). CRF achieved via a treadmill workout has been shown to significantly increase body sway during balance tasks compared to pre- fatigue values. Additionally, it has been shown that increasing backpack loads decreases balance ability. PURPOSE: The purpose of this study is to combine these two ideas to assess the effect of loaded backpack usage on balance by quantitatively measuring balance after a functional daily stair task (FDST) designed to resemble CRF. METHODS: 7 male and 13 …

High Salt Intake Augments Excitability Of Pvn Neurons In Rats: Role Of The Endoplasmic Reticulum Ca2+ Store, Robert A. Larsen, Andrew D. Chapp, Le Gui, Michael J. Huber, Zixi Jack Cheng, Zhiying Shan, Qing-Hui Chen

Department of Kinesiology and Integrative Physiology Publications

High salt (HS) intake sensitizes central autonomic circuitry leading to sympathoexcitation. However, its underlying mechanisms are not fully understood. We hypothesized that inhibition of PVN endoplasmic reticulum (ER) Ca²⁺ store function would augment PVN neuronal excitability and sympathetic nerve activity (SNA). We further hypothesized that a 2% (NaCl) HS diet for 5 weeks would reduce ER Ca²⁺ store function and increase excitability of PVN neurons with axon projections to the rostral ventrolateral medulla (PVN-RVLM) identified by retrograde label. PVN microinjection of the ER Ca²⁺ ATPase inhibitor thapsigargin (TG) increased SNA and mean arterial pressure (MAP) in a …

Glenohumeral Internal Rotation Deficit In Division Three Collegiate Football Quarterbacks, Anthony Wene

Undergraduate Honors Thesis Projects

The research looked at the internal rotation loss in collegiate football quarterbacks. A goniometer was used to measure the internal and external rotation of the shoulder for each subject. These measurements were then compared to what is considered glenohumeral internal rotation deficit, GIRD, as defined in the literature. A majority of the current literature focused on GIRD and its connection to baseball pitchers. This research focused on GIRD and its possible connection to football quarterbacks because of the repetitive overhead motion. GIRD is often connected to baseball pitchers due to the extensive research done with baseball pitchers. There are several …

Head Out Of Water Weighing: A Valid Method To Measure Body Fat Storage?, Molly Hussey

Annual Graduate Student Symposium

Underwater weighing with full lung expiration has been established as a valid method to assess body composition. Many people do not prefer this method due to various reasons. Hydrostatic weighing with head above water at full lung capacity has been tested although not accepted as an alternative method. Purpose: The main purpose of this study is to examine if hydrostatic weighing with the head above water could be a better method to measure body composition. Methods: Fifty-nine subjects (F=29, M=30) participated in performing four different methods of underwater weighing: complete immersion at full lung expiration (UWWRV) and total lung capacity …

Rehabilitation For Surgically Repaired Acetabular Labrum, Courtney Roberts, H Dean, S Holland

Thinking Matters Symposium Archive

Acetabular labral tears were once thought to be an uncommon injury. With advancements in modern medicine such as improvements in imaging technologies and arthroscopy techniques, hip and groin pain associated with an ALT is less likely to be missed or go un-diagnosed. With the growing prevalence, it is important for athletic trainers and physical therapists to have a protocol to follow for rehabilitation. The purpose of our research was to investigate treatment strategies for surgically repaired acetabular labral tears, and to develop a exercise protocol for a young athlete from the acute phase of injury through return-to-sport. This will assist …

Anatomic Femoral And Tibial Tunnel Placement During Anterior Cruciate Ligament Reconstruction: Anteromedial Portal All-Inside And Outside-In Techniques, Jeremy M. Burnham, Chaitu S. Malempati, Aaron Carpiaux, Mary Lloyd Ireland, Darren L. Johnson

Orthopaedic Surgery and Sports Medicine Faculty Publications

Tunnel malposition is one of the most common technical reasons for anterior cruciate ligament reconstruction failure. Small changes in tunnel placement can result in significant differences in outcome. More anatomic placement of the tunnels can lead to greater knee stability and a more accurate reproduction of native knee kinematics. This Technical Note describes 2 tibial tunnel–independent methods to obtain anatomic femoral tunnel placement. The all-inside anteromedial portal technique requires only minimal surgical incisions but allows precise femoral tunnel placement. However, hyperflexion of the knee is required, adequate surgical assistance is necessary, and this technique may be susceptible to graft-tunnel mismatch. …

Flexible Dieting And Metabolic Adaptation During Weight Loss: A Comprehensive Review, Bryce Lahaie

Senior Honors Projects

Flexible dieting is a ubiquitous method of eating among the fitness population. It is not a diet, but rather a nutritional concept that refutes any diet that promotes cutting out entire foods or food groups as a method to lose weight. It is a structured and science-based method of eating that involves tracking calories through monitoring the three main macronutrients: carbohydrates, fats, and proteins. These macronutrients are individualized and adjusted for muscle growth, fat loss, or weight maintenance in order to optimize intake to facilitate the manipulation of body composition. Flexible dieting is a disciplined method of eating that teaches …

Superior Effects Of Eccentric To Concentric Knee Extensor Resistance Training On Physical Fitness, Insulin Sensitivity And Lipid Profiles Of Elderly Men, Trevor Chung-Ching Chen, Wei-Chin Tseng, Guan-Ling Huang, Hsin-Lian Chen, Kuo-Wei Tseng, Kazunori Nosaka

Research outputs 2014 to 2021

It has been reported that eccentric training of knee extensors is effective for improving blood insulin sensitivity and lipid profiles to a greater extent than concentric training in young women. However, it is not known whether this is also the case for elderly individuals. Thus, the present study tested the hypothesis that eccentric training of the knee extensors would improve physical function and health parameters (e.g., blood lipid profiles) of older adults better than concentric training. Healthy elderly men (60–76 years) were assigned to either eccentric training or concentric training group (n=13/group), and performed 30–60 eccentric or concentric …

Acute Elevations In Serum Hormones Are Attenuated After Chronic Training With Traditional Isoinertial But Not Accentuated Eccentric Loads In Strength-Trained Men, Simon Walker, Keijo Häkkinen, Greg Haff, Anthony J. Blazevich, Robert Newton

Research outputs 2014 to 2021

It has been proposed that the maintenance of acute hormonal responses reveal an efficacy of a training stimulus to evoke ongoing increases in strength and muscle mass. We previously observed that maximum strength continued to improve throughout a 10‐week period in an accentuated eccentric loading group (AEL) but not a traditional isoinertial loading (ISO) group. Therefore, this study investigated whether the magnitude of acute hormonal responses was greater (i.e., maintained) in AEL compared to ISO at the end of the training period. Subjects in AEL (eccentric load = concentric load + 40%) and ISO performed experimental loading tests (three sets …

Prevention Of Downhill Walking-Induced Muscle Damage By Non-Damaging Downhill Walking, Sumiaki Maeo, Masayoshi Yamamoto, Hiroaki Kanehisa, Kazunori Nosaka

Research outputs 2014 to 2021

Purpose:

Mountain trekking involves level, uphill, and downhill walking (DW). Prolonged DW induces damage to leg muscles, reducing force generating ability and muscle coordination. These increase risks for more serious injuries and accidents in mountain trekking, thus a strategy to minimize muscle damage is warranted. It has been shown that low-intensity eccentric contractions confer protective effect on muscle damage induced by high-intensity eccentric contractions. This study tested the hypothesis that 5-min non-damaging DW would attenuate muscle damage induced by 40-min DW, but 5-min level walking (LW) would not.

Methods:

Untrained young men were allocated (n = 12/group) to either a …

Effects Of Height Increasing Heel Insole On Lower Extremity Joint Mechanics, Youngwook Kim

UNO Student Research and Creative Activity Fair

High-heel shoes alter foot pressure distribution and lower extremity kinetic and kinematics. Unlike general women’s high-heeled shoes, height increasing heel insoles are cushioned, which may contribute to impact absorption. The purpose of this study is to compare the kinetic and kinematics of gaits with and without height increasing heel insoles. Two male subjects performed level walking under two conditions: wearing sports shoes with and without height increasing heel insoles which added additional 5 cm of the heel height (total 6 cm). The vertical ground reaction force (GRF), angle, moment, and power of ankle, knee, and hip during the stance phase …

The Effects Of Different Exercise Training Modalities On Plasma Proenkephalin Peptide F In Women, William H. Dupont, William J. Kraemer, Bradley C. Nindl, Elaine C. Lee, Maren S. Fragala, Disa L. Hatfield, Lydia K. Caldwell, Emily M. Post, Matthew K. Beeler, Jeff S. Volek, Carl M. Maresh

Health and Sport Sciences Faculty Scholarship

Due to the important interactions of proenkephalin fragments (e.g., proenkephalin [107–140] Peptide F) to enhance activation of immune cells and potentially combat pain associated with exercise-induced muscle tissue damage, we examined the differential plasma responses of Peptide F to different exercise training programs. Participants were tested pre-training (T1), and after 8 weeks (T2) of training. Fiftynine healthy women were matched and then randomly assigned to one of four groups: heavy resistance strength training (STR, n = 18), high intensity endurance training (END, n = 14), combined strength and endurance training (CMB, n = 17), or control (CON, n = 10). …
