The Effects Of Two Different Fatigue Protocols On Lower Extremity Kinematics And Kinetics During An Unanticipated Running Stop-Jump, David L. Quammen 2010 Old Dominion University

The Effects Of Two Different Fatigue Protocols On Lower Extremity Kinematics And Kinetics During An Unanticipated Running Stop-Jump, David L. Quammen

Human Movement Studies & Special Education Theses & Dissertations

Altered neuromuscular control strategies and biomechanical movement risk factors are most likely to contribute to the increased incidence of non-contact ACL injury for female athletes. Neuromuscular control strategies and movement patterns are further altered when the effects of fatigue are present. The purpose of this study was to determine neuromechanical differences between two fatigue protocols [Slow Linear Oxidative Fatigue Protocol (SLO-FP) and Functional Agility Short-Term Fatigue Protocol (FASTFP)] when performing a running stop-jump task (RS). A sample of convenience of fifteen Division I female soccer players (age= 19.2 ± 0.8 years; height= 1.67 ± 0.05 m; mass= 61.7 ± 8.1 …


The Correlation Between Visual Observations And Inclinometric Measurements For Special Tests Related To Patellofemoral Pain Syndrome, Erin Quada 2010 Old Dominion University

The Correlation Between Visual Observations And Inclinometric Measurements For Special Tests Related To Patellofemoral Pain Syndrome, Erin Quada

Human Movement Studies & Special Education Theses & Dissertations

Patellofemoral pain syndrome (PFPS) is generally described as an insidious onset with pain increasing during running, jumping, ascending and descending stairs as well as sitting with the knees flexed for an extended period of time. Clinicians often use special tests in injury evaluations and range of motion assessments, usually making a visual observation of that status of the patient. The purpose of this study was to examine how interval measurements utilized in flexibility and range of motion assessments correlate with visual observations of special tests (active knee extension test, Thomas test, Ober's test, rectus femoris flexibility, and Craig's test). The …


The Effects Of Two Types Of Fatigue On An Unanticipated Side-Step Cutting Task As Measured By Kinematic And Kinetic Variables, Shawn E. Lucci 2010 Old Dominion University

The Effects Of Two Types Of Fatigue On An Unanticipated Side-Step Cutting Task As Measured By Kinematic And Kinetic Variables, Shawn E. Lucci

Human Movement Studies & Special Education Theses & Dissertations

Fatigue has been shown to alter the neuromechanics of lower extremity. To date, no study has examined the effects of two types of fatigue on kinetics and kinematics. To determine neuromechanical differences between two fatigue protocols [Slow Linear Oxidative Fatigue Protocol (SLO-FP) and Functional Agility Short-Term Fatigue Protocol (FAST-FP)] when performing an unanticipated sidestep cutting task. Fifteen female collegiate soccer players (age=19.2±0.8 years; height=l.67±0.05m; mass=61.7±8.lkg) participated in this study. Participants were free of lower extremity injury at time of participation, and performed five successful trials of a sidestep cutting (SS) task pre and post fatigue protocols. For the SLO-FP, a …

A Rapid, Flow Cytometry-Based Assay For The Determination Of Natural Killer Cell Activity In Isolated Periphery Blood Mononuclear Cells, Emily C.P. LaVoy, Brian K. McFarlin 2010 University of Houston - Main

A Rapid, Flow Cytometry-Based Assay For The Determination Of Natural Killer Cell Activity In Isolated Periphery Blood Mononuclear Cells, Emily C.P. Lavoy, Brian K. Mcfarlin

International Journal of Exercise Science: Conference Proceedings

Natural killer cell activity (NKCA) is an important assessment of innate immunity in humans. Natural killer (NK) cells are known to be affected by exercise; therefore it is of interest to have an efficient method for measuring NKCA in pre- and post-exercise blood samples. Assays for NKCA include incubating human NK cells (effector cells) with stained target cells. The target cells are typically from the human leukemia cell line K562. The number of K562 target cells killed can be determined using a dead cell dye. Control target cells incubated alone provide a measure of spontaneous cell death. PURPOSE: The purpose …


Corticosterone Levels In Sedentary, Wheel, And Treadmill Acclimated Mice Following A Bout Of Forced Treadmill Running, Nadia H. Agha, Joesph Potucek, Kelley Strohacker, Whitney L. Breslin, Brian K. McFarlin 2010 University of Houston - Main

Corticosterone Levels In Sedentary, Wheel, And Treadmill Acclimated Mice Following A Bout Of Forced Treadmill Running, Nadia H. Agha, Joesph Potucek, Kelley Strohacker, Whitney L. Breslin, Brian K. Mcfarlin

International Journal of Exercise Science: Conference Proceedings

Murine models have been used to study the immune response to exercise under various diet and training interventions .Our laboratory has previously studied the effect of forced exercise versus voluntary exercise on fasting blood glucose measurements. However, forced exercise may result in increased corticosterone levels. This may affect glucose levels and subsequent weight gain. Male, wild-type CD-1 mice were randomly divided into the following groups: forced exercise, wheel running, and sedentary. After a 8- weeks of the intervention, all mice were placed on a treadmill and forced to run for 30 minutes. Blood was collected from the mice prior to …


No Impact Of Cmv Or Ebv Seropositivity On The Frequency Of Highly Differentiated T-Cells In Mexican-American Adolescents, Guillaume Spielmann, Craig A. Johnston, Richard J. Simpson, Brian K. McFarlin, John P. Foreyt 2010 University of Houston

No Impact Of Cmv Or Ebv Seropositivity On The Frequency Of Highly Differentiated T-Cells In Mexican-American Adolescents, Guillaume Spielmann, Craig A. Johnston, Richard J. Simpson, Brian K. Mcfarlin, John P. Foreyt

International Journal of Exercise Science: Conference Proceedings

Recurring activations of the prevalent latent herpes viruses Cytomegalovirus (CMV) and Epstein-Barr virus (EBV) induces immune cell division leading to the premature terminal differentiation of T-cells. Terminally differentiated T-cells are known to accumulate with age causing a reduction in the naïve T-cell repertoire, which compromises the ability of the adaptive immune system to respond to novel pathogens. Although CMV and EBV seropositivity are hallmarks of the “immune risk profile” and are known to influence the frequency of terminally differentiated T-cells and increase infection risk in adults, it is not known if CMV or EBV impacts on the frequency of these …


The Effects Of Exercise And A Low-Fat Diet On Monocyte Tlr Expression And Disease Risk In Mice, Katie C. Carpenter, Kelley Strohacker, Whitney Breslin, Nadia Agha, Thomas W. Lowder, Richard J. Simpson, Brian K. McFarlin 2010 University of Houston - Main

The Effects Of Exercise And A Low-Fat Diet On Monocyte Tlr Expression And Disease Risk In Mice, Katie C. Carpenter, Kelley Strohacker, Whitney Breslin, Nadia Agha, Thomas W. Lowder, Richard J. Simpson, Brian K. Mcfarlin

International Journal of Exercise Science: Conference Proceedings

Excess adiposity increases systemic inflammation, which is implicated in various diseases. Physical activity is a common treatment to reverse weight gain and increased disease risk; however, little evidence is available to determine if forced or voluntary exercise is more effective in mice. Such information has implications for the refinement of human exercise interventions. PURPOSE: To determine if 8-weeks of exercise combined with low-fat feeding reverses changes in disease risk, monocyte concentration and monocyte TLR2/TLR4 expression. METHODS: For 12-months, 24 CD-1 mice underwent pre-treatment, consuming either a low-fat (10% kcal from fat, N=6) or high-fat (60% kcal from fat, N=18) diet …


Cell-Surface Receptor Expression On Monocytes Of Young And Old Mice, Kelley Strohacker, Whitney L. Breslin, Brian K. McFarlin 2010 University of Houston

Cell-Surface Receptor Expression On Monocytes Of Young And Old Mice, Kelley Strohacker, Whitney L. Breslin, Brian K. Mcfarlin

International Journal of Exercise Science: Conference Proceedings

Background. Monocyte assessment is used in aging research. In humans, reduced expression of toll-like receptors, T-lymphocyte priming receptors and increases in intracellular adhesion molecules on monocytes have been associated with functional decrements, resulting in increased disease risk. While use of mouse models is extensive in aging research, mouse monocyte assessment is rare. We aimed to evaluate differences in cell-surface protein expression in classic (CD115+/Gr-1high) and non-classic (CD115+/Gr-1low) monocyte subsets of old and young mice. Methods. Venous blood was drawn from 18 old (80-wks) and 18 young CD-1 mice (15-20-wks). Flow cytometry was used to assess subpopulations of CD115+ monocytes for …
