The Effect Of Various Body Positions On Performance Of The Isometric Mid-Thigh Pull, George K. Beckham
Electronic Theses and Dissertations
The purpose of this dissertation was to evaluate the effects of changing body position on the execution of the isometric mid-thigh pull (IMTP). Furthermore, while there is evidence to suggest that there is an effect of familiarization on performance of maximal strength tests, there has been no known research evaluating the effect of learning on the IMTP. The effect of familiarization was assessed by evaluating changes in variables obtained from the IMTP. Subjects did not statistically improve over the five IMTP testing sessions, regardless of the body position used, or if subjects had previous experience with weightlifting derivatives. This may …

Negative Skeletal Effects Of Locally Produced Adiponectin, Marcia J. Abbott, Theresa M. Roth, Linh Ho, Liping Wang, Dylan O'Carroll, Robert A. Nissenson
Health Sciences and Kinesiology Faculty Articles
Epidemiological studies show that high circulating levels of adiponectin are associated with low bone mineral density. The effect of adiponectin on skeletal homeostasis, on osteoblasts in particular, remains controversial. We investigated this issue using mice with adipocyte-specific over-expression of adiponectin (AdTg). MicroCT and histomorphometric analysis revealed decreases (15%) in fractional bone volume in AdTg mice at the proximal tibia with no changes at the distal femur. Cortical bone thickness at mid-shafts of the tibia and at the tibiofibular junction was reduced (3–4%) in AdTg mice. Dynamic histomorphometry at the proximal tibia in AdTg mice revealed inhibition of bone formation. AdTg …

Journal Articles
In rehabilitation, rhythmic acoustic cues are often used to improve gait. However, stride-time fluctuations become anti-persistent with such pacing, thereby deviating from the characteristic persistent long-range correlations in stride times of self-paced walking healthy adults. Recent studies therefore experimented with metronomes with persistence in interbeat intervals and successfully evoked persistent stride-time fluctuations. The objective of this study was to examine how participants couple their gait to a persistent metronome, evoking persistently longer or shorter stride times over multiple consecutive strides, without wandering off the treadmill. Twelve healthy participants walked on a treadmill in self-paced, isochronously paced and non-isochronously paced conditions, …

Understanding Stress And Aggression Behaviors Among Urban Youth, Erin E. Centeio, Laurel Whalen, Noel Kulik, Erica Thomas, Nate Mccaughtry
Kinesiology, Health and Sport Studies
Background/Objective: Youth violence, including school bullying and fighting, has become a global public health problem. Stress has been identified as a factor related to aggression (i.e., bullying behaviors, fighting, and anger), of which inner-city youth are particularly vulnerable given their often disproportionately high stress living environments. Stress and aggression are of particular concern in urban physical education (PE) given the proliferation of competitive, sport-based curricula, “culture of basketball”, and the often-limited supervision that takes place. Using the Social Ecological Model, the purpose of this study was to examine the relationships between stress and aggression in inner-city elementary PE students. …

Sympathetic Neural Recruitment Strategies: Responses To Severe Chemoreflex And Baroreflex Stress, Mark B. Badrov, Charlotte W. Usselman, J Kevin Shoemaker
Kinesiology Publications
This study tested the hypothesis that neural coding patterns exist within the autonomic nervous system. We investigated sympathetic axonal recruitment strategies in humans during chemoreflex- and baroreflex-mediated sympathoexcitation using a novel action potential (AP) analysis technique. Muscle sympathetic nerve activity (microneurography) was collected in 11 young individuals (6 females) during baseline and two subsequent protocols: 1) severe chemoreflex stimulation (maximal end-inspiratory apnea following rebreathe), and 2) severe baroreceptor unloading (−80 mmHg lower body negative pressure; LBNP). When compared with each respective baseline, apnea and LBNP increased AP frequency and mean AP content per sympathetic burst (all P < 0.01). When APs were binned according to peak-to-peak amplitude (i.e., into “clusters”), total clusters detected increased during both apnea (Δ7 ± 5; P …

Use And Misuse Of The Likert Item Responses And Other Ordinal Measures, Phillip A. Bishop, Robert L. Herron
International Journal of Exercise Science
International Journal of Exercise Science 8(3): 297-302, 2015. Likert, Likert-type, and ordinal-scale responses are very popular psychometric item scoring schemes for attempting to quantify people’s opinions, interests, or perceived efficacy of an intervention and are used extensively in Physical Education and Exercise Science research. However, these numbered measures are generally considered ordinal and violate some statistical assumptions needed to evaluate them as normally distributed, parametric data. This is an issue because parametric statistics are generally perceived as being more statistically powerful than non-parametric statistics. To avoid possible misinterpretation, care must be taken in analyzing these types of data. The use …

Trx Suspension Training: A New Functional Training Approach For Older Adults - Development, Training Control And Feasibility, Angus Gaedtke, Tobias Morat
International Journal of Exercise Science
International Journal of Exercise Science 8(3): 224-233, 2015. Because of its proximity to daily activities functional training becomes more important for older adults. Sling training, a form of functional training, was primarily developed for therapy and rehabilitation. Due to its effects (core muscle activation, strength and balance improvements), sling training may be relevant for older adults. However, to our knowledge no recent sling training program for healthy older adults included a detailed training control which is indeed an essential component in designing and implementing this type of training to reach positive effects. The purpose of this study was to develop …

Sensitivity Of Prescribing High-Intensity, Interval Training Using The Critical Power Concept, Robert W. Pettitt, Ashley M. Placek, Ida E. Clark, Nicholas A. Jamnick, Steven R. Murray
International Journal of Exercise Science
International Journal of Exercise Science 8(3): 202-212, 2015. The critical power (CP) concept enables the calculation of time to exhaustion (tLIM) for a given power output above CP using the equation of tLIM = W’/(power – CP), where W’ is the curvature constant, and CP is the asymptote for the power-tLIM relationship. The CP concept offers great promise for prescribing high-intensity interval training (HIIT); however, knowledge on the concept’s sensitivity is lacking (i.e., how much of a difference in W’ expenditure is needed to evoke different metabolic responses). We tested if two …
