  • 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...

  • Effect of leg muscle fatigue on the contributions of the somatosensory, visual, and vestibular systems to balance

    Creator:
    Korioukhina, Maia O.
    Abstract:
    Objectives: To evaluate the effect of leg muscle fatigue on balance and to determine the contributions of the somatosensory, visual, and vestibular systems to balance of apparently healthy males and females. Design: Forty-two subjects were randomly assigned to either the experimental or control groups and then subdivided based on gender...

  • Performance in static, dynamic, and clinical tests of postural control in individuals with functional ankle instability

    Creator:
    Nakagawa, Lyn H.
    Abstract:
    Objectives: To evaluate postural control in individuals with functional ankle instability using static, dynamic, and clinical balance tests. Also, to examine the relationships between the performances in each of these tests. Design: Postural control was evaluated with a single leg balance test, a balance test involving movement, and the star...

  • A comparison of two neuropsychological concussion assessment batteries

    Creator:
    Padilla, Diana M.
    Abstract:
    Objectives: To compare the neuropsychological concussion assessment testing batteries of the Standardized Assessment of Concussion (SAC™) test and the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT™) test and determine if the tests measure similar neuropsychological functions as well as determine the test-retest reliability of the pre and post season measures...

  • 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 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...

  • Spinal control mechanisms in elite level, explosively-trained athletes from two different sports

    Creator:
    Zidek, Marie E.
    Abstract:
    Mechanisms of motor control and function are interesting to those from the medical, athletic training and sports performance professions primarily during the development of conditioning and rehabilitation programs. The aim of this study was to assess spinal control mechanisms in two groups of explosively trained, female athletes from a NCAA...

  • 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...

  • 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...
