Development Of A Technique To Diagnose Subtalar Joint Instability, Ajaya Dhakal

Mechanical & Aerospace Engineering Theses & Dissertations

Most patients escape diagnosis of subtalar joint instability for years before treatment. Therefore, a clinically relevant technique to diagnose subtalar joint instability will improve its management. Towards this goal, a six degree of freedom positioning and loading device was developed to apply physiologic loads to the hindfoot. Because the ideal loading configuration to detect subtalar joint instability is unknown, the device was designed to apply rotational and translational forces simultaneously. Specifically, plantarflexion/dorsiflexion, inversion/eversion, and internal/external rotation can be applied individually or as coupled motions along with an anterior/posterior drawer. Kinematic data were collected from calcaneus, talus and tibia using a …

The Effect Of Intensity Of Aerobic Training On Insulin Sensitivity, Carmine Richard Grieco Iii

Human Movement Studies & Special Education Theses & Dissertations

Epidemiological studies have demonstrated that the prevalence of type 2 diabetes is increasing. It is estimated that I 0. 7% of adults over the age of 20 years and 23.1 % of adults over the age of 60 years have diabetes (NIH, 2007). Individuals with type 2 diabetes are 2-4 times more likely to die from heart disease than those without diabetes and twice as likely to die of all-cause mortality (CDC, 2005). Additionally Mokdad et al. (2000) report that the prevalence of diabetes increased 33% between 1990 and 1998. Furthermore it has been estimated that nearly 26% of the …

Gender Differences And Biomechanics In The 3000m Steeplechase Water Jump, Kassi R. Andersen, Bryan K. Lindsay, Iain Hunter

Faculty Publications

Since 1996, women have been competing in the 3000m steeplechase race internationally. Whenever women and men both compete in similar events with different equipment (the barriers are lower for women) consideration should be given as to how techniques should be coached differently. This study investigated the differences in water-jump technique between men and women after accounting for differences in running speed and which techniques led to maintenance of race pace through the water-jump. Eighteen men and 18 women were filmed at two major track and field meets during the 2004 season. Peak Motus 8.2 was used to digitize all seven …

Relationship Of Vo2 Peak, Body Fat Percentage, And Power Output Measured During Repeated Bouts Of A Wingate Protocol, John R. Mclester‡, J. Matthew Green‡, P. Jason Wickwire†, Thaddeus R. Crews‡

International Journal of Exercise Science

The principle of specificity would indicate that being aerobically trained would not necessarily enhance performance in events relying principally on oxygen-independent metabolic pathways (i.e. “anaerobic” exercise). Body fatness may be associated with aerobic and anaerobic performance. VO2 Peak was determined with a graded cycle ergometry and, in a separate session 4 consecutive Wingate power tests (3 min recovery) in 31 males. Pearson correlations were calculated for VO2 Peak and Body Fat Percentage with Peak Power, Mean Power, Minimum Power, Fatigue Index, Peak Heart Rate, and Recovery Heart Rate. No significant correlations were found for VO2 Peak or Body Fat Percentage …

Ground Reaction Force Profiles In Acl Reconstructed Female Athletes, Ashley Mcgavern

Kinesiology Theses - Archive

Injury to the anterior cruciate ligament (ACL) has become a global topic of research, as the number of injuries is staggering and continues to increase each year because the underlying elements contributing to this injury have yet to be fully grasped. It is estimated that 80,000 – 250,000 ACL injuries occur annually in female athletics.(45) As a result, an estimated number of 100,000 ACL reconstructions are performed annually.(2) The uncertainty involving the contributing causes of this injury has naturally ushered uncertainty involving the treatment of the injury, i.e. surgical repair and subsequent rehabilitation. Although considerable gains toward improving surgical procedure …

Exercise, Apoe, And Working Memory: Meg And Behavioral Evidence For Benefit Of Exercise In Epsilon4 Carriers, Sean P. Deeny, David Poeppel, Jo B. Zimmerman, Stephen M. Roth, Josef Brandauer, Sarah Witkowski, Joseph W. Hearn, Andrew T. Ludlow, José L. Contreras-Vidal, Jason Brandt, Bradley D. Hatfield

Exercise and Sport Studies: Faculty Publications

Performance on the Sternberg working memory task, and MEG cortical response on a variation of the Sternberg task were examined in middle-aged carriers and non-carriers of the APOE ε4 allele. Physical activity was also assessed to examine whether exercise level modifies the relationship between APOE genotype and neurocognitive function. Regression revealed that high physical activity was associated with faster RT in the six- and eight-letter conditions of the Sternberg in ε4 carriers, but not in the non-carriers after controlling for age, gender, and education (N = 54). Furthermore, the MEG analysis revealed that sedentary ε4 carriers exhibited lower right temporal …

Distinct Timing Mechanisms Produce Discrete And Continuous Movements, Raoul Huys, Breanna E. Studenka, Nicole L. Rheaume, Howard N. Zelaznik, Viktor K. Jirsa

Kinesiology and Health Science Faculty Publications

The differentiation of discrete and continuous movement is one of the pillars of motor behavior classification. Discrete movements have a definite beginning and end, whereas continuous movements do not have such discriminable end points. In the past decade there has been vigorous debate whether this classification implies different control processes. This debate up until the present has been empirically based. Here, we present an unambiguous non-empirical classification based on theorems in dynamical system theory that sets discrete and continuous movements apart. Through computational simulations of representative modes of each class and topological analysis of the flow in state space, we …

Do The Principles Of Motor Program Editing Apply To Longer Sequences Of Rapid Aiming Movements? Part Ii, Eric J. Wilson*, David E. Sherwood‡

International Journal of Exercise Science

In Part I of this study, it was shown that performing a shorter distance aiming movement prior to a longer distance aiming movement resulted in overshooting of the short movement and undershooting of the longer movement compared to control conditions. However, the finding was limited, unexpectedly, to the nondominant hand. To replicate the prior result and to determine the effect of practice organization on movement accuracy, right-handed (n =24) participants (aged 18-22) produced a sequence of three rapid lever reversals combining short (20°) and long (60°) movements with an intermovement interval of 2.5 s with the dominant hand. Greater overshooting …
