Efficacy Of Pre-Activity Stretching, Michelle Nicole Samuel Jan 2006

Efficacy Of Pre-Activity Stretching, Michelle Nicole Samuel

UNLV Retrospective Theses & Dissertations

Pre-activity stretching is commonly performed by athletes as part of their warm-up routine. However, the most recent literature questions the effectiveness of pre-activity stretching. Some literature suggests that pre-activity stretching hinders athletic performance, while others suggest that stretching does not affect performance. Since a clear answer has not yet been determined on pre-activity stretching, this study was designed to investigate the acute effects of static vs. ballistic stretching on vertical jump performance, and torque and power output of the quadriceps and hamstrings, and to compare the effects of stretching between genders. The goal was to determine if pre-activity stretching is …

Verbal And Nonverbal Mitigating Communication On Information Processing And Anger, Rebecca L Thomas Jan 2006

Verbal And Nonverbal Mitigating Communication On Information Processing And Anger, Rebecca L Thomas

UNLV Retrospective Theses & Dissertations

Frustration, anger, and aggression have been linked in the literature. Studies have shown that participants are capable of using verbal and nonverbal communication to display and interpret emotions. One interesting communication phenomena is mitigating information, this would include an apology or an explanation. The fundamental attribution error posits that people attribute an individual's behavior to dispositional characteristics more often than situational components. In the current study participants were undergraduate psychology students recruited for a study investigating social interaction. Participants engaged in a frustrating interaction and encountered one of four communication conditions. These included verbal or nonverbal communication, with and without …

Tibial Rotation And Valgus Movement At The Knee During Cutting And Stopping, Amanda Tritsch Jan 2006

Tibial Rotation And Valgus Movement At The Knee During Cutting And Stopping, Amanda Tritsch

UNLV Retrospective Theses & Dissertations

This study was performed to examine tibial rotation and valgus movement at the knee during dynamic sport-specific movements, a jump stop and a side cut maneuver associated with anterior cruciate ligament (ACL) injury. We aimed to assess whether six male and eight female skilled soccer athletes perform these maneuvers with different magnitudes of valgus movement and tibial rotation at the knee. Nine trials of each maneuver were analyzed for each subject. There was a significant difference between males and females for valgus angle at contact, maximum valgus angle, and maximum external rotation (p<0.05). There was no difference for any dependant variable between jump stop and side cut maneuver, and Sex * Maneuver no interaction. Though there is certainly more than one reason for greater number of ACL injuries in females, not finding a difference in valgus movement between the sexes may indicate that tibial rotation might play a greater role than valgus movement alone.

Gamma-Aminobutyric Acid Inhibits Cytokine-Mediated Synergistic Induction Of Astrocytic Interleukin-6 Release: A Mechanistic Study, Grant Toshio Aguinaldo

UNLV Retrospective Theses & Dissertations

A paucity of gamma-aminobutyric acid (GABA) levels is thought to encourage cytokine release in Alzheimer's disease (AD). A mechanistic investigation into the GABA-mediated suppression of the synergistic release of interleukin (IL)-6 by IL-1beta and tumor necrosis factor (TNF)-alpha is presented. Preliminary results indicate that p38 and nuclear factor (NF)-kappaB are essential for the synergistic release of IL-6 by IL-1beta and TNF-alpha. Both IL-1beta and TNF-alpha are able to stimulate the phosphorylation of p38, however, no synergistic stimulation was observed. IL-1beta or TNF-alpha is able to stimulate the degradation of the NF-kappaB inhibitor, IkappaB-alpha, with no change in IkappaB-beta. Interestingly, TNF-alpha …

Bioaccumulation Of Mercury In The Aquatic Food Chain Of Walleye (Stizostedion Vitreum) In Lake Siskiwit, Northern Wisconsin, United States, Beth Ellen Domowicz

UNLV Retrospective Theses & Dissertations

The Great Lakes fishery is highly utilized, despite known contamination. The Great Lakes Region has experienced elevated amounts of atmospheric deposition of mercury, with many of its water bodies having documented levels of mercury (ASTDR 1999, Dellinger 2004, Greib et al. 1990, Kleinert and Degurse 1971). The chemical characteristics of methylmercury contribute to high rates of absorption (highly lipophilic and readily crosses biological membranes) and low rates of elimination. As a result of the properties of methylmercury, 60-90% of the mercury in fish is methylmercury (O'Neill 1993). Methylmercury is taken in by fish from food sources, through the gills (Haydon …
