  • The effects of whole body vibration on the neuromuscular system

    Creator:
    Hong, Junggi
    Abstract:
    Recently, changes in human performance following whole-body vibration (WBV) training have been attributed to enhanced neuromuscular function. However, the exact neural and muscular mechanisms responsible for these changes remain less understood. The purpose of this study was to evaluate the acute and chronic effects of whole body vibration on the...

  • Spinal reflex control in healthy and ACL-injured women during a distracting task

    Creator:
    Perrier, Erica Taylor
    Abstract:
    Female athletes exhibit three- to six-fold greater incidence of noncontact anterior cruciate ligament (ACL) injury relative to their male counterparts. The increased risk appears to stem from interactions between several risk factors, that can roughly be categorized as anatomic, biomechanical, hormonal, and neuromuscular. Neuromuscular risk factors have recently gained a...

  • The neuromuscular effects of a long-term static stretching program on the human soleus

    Creator:
    Hayes, Bradley T.
    Abstract:
    The purpose of this research was to evaluate the effects of a long-term static stretching program on flexibility and spinal reflexes in the human soleus muscle. Day-to-day reliability over two days of H-reflex gain (Hslp/Mslp) and pre-synaptic inhibition of spinal reflexes in the human soleus was measured in an initial...

  • Spinal control differences between the sexes

    Creator:
    Johnson, Samuel T.
    Abstract:
    Despite years of research, females continue to have a higher incidence of non-contact ACL injuries. One of the major findings of this research is that males and females perform certain tasks, such as, cutting, landing, and single-leg squatting, differently. In particular, females tend to move the knee into a more...

  • The effects of plyometrics on neuromuscular control

    Creator:
    Doeringer, Jeffrey R.
    Abstract:
    The purpose of this study was to determine the effects of plyometric training on both spinal and supraspinal motor control as well as the rate of torque development (RTD) in healthy active females. Thirty-one subjects were recruited to participate in the study and participated in either the training or control...

  • The Relationship between Student Health Behaviors, Demographic Variables and Suicide: A Secondary Analysis of Health Behaviors in School-Age Children (HBSC 2009-2010)

    Creator:
    Hoffman, Lora K.
    Abstract:
    Counselors, therapists and other mental health professionals are dedicated to finding more useful ways to prevent, assess and treat adolescents experiencing suicidal ideation. Recent research has shown that the use of Interpersonal-Psychological Theory of Suicide (IPTS) components in suicidal assessment and treatment have been effective for treating adults. However, a...

  • Calcium regulation and physiological function in animals exposed to lead

    Creator:
    Hoffman, Norbert Edward
    Abstract:
    Tissue distribution studies of calcium and lead in brain tissue of rats were increased subsequent to a single intravenous injection of lead, 10 mg/kg, in the form of lead acetate. Time-course studies demonstrated that brain concentrations of calcium and lead (in terms of wet tissue weight) were found to be...

  • Ocean Temperature Variability during the Late Pleistocene

    Creator:
    Hoffman, Jeremy Scott
    Abstract:
    This dissertation explores one overarching question relevant to the paleoclimate of the latest Pleistocene glacial cycle (approximately the last 130,000 years): “How did spatial and temporal evolution of ocean temperature, both at the surface and interior, relate to other parts of the climate system in the late Pleistocene?” Results from...

  • Natural history and evolution of a color polymorphism in Rana pipiens, the northern leopard frog

    Creator:
    Hoffman, Eric A.
    Abstract:
    A primary goal of population genetics is to identify the role of microevolutionary forces in producing observed patterns of molecular and phenotypic variation. I conducted four studies in the northern leopard frog, Rana pipiens, to determine just how mutation, migration, genetic drift, and selection influenced, genetic structure of mitochondrial DNA...

  • Investigation of the biomechanics of running and rapid change-of-direction tasks

    Creator:
    Golden, Grace M.
    Abstract:
    Rapid change-of-direction tasks have been associated with non-contact anterior cruciate ligament (ACL) injuries and females are more likely to suffer this injury compared to males. The purpose of this investigation was to evaluate the biomechanical behavior of running and three rapid change-of-direction tasks and determine whether sex differences exist across...
