Effects Of Footstrike Pattern On Low Back Posture, Shock Attenuation, And Comfort During Running, Traci L. Delgado, Emilia Kubera-Shelton, Robert R. Robb

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose: Barefoot running (BF) is popular in the running community. Biomechanical changes occur with BF, especially when initial contact changes from rearfoot strike (RFS) to forefoot strike (FFS). In addition, changes in lumbar spine range of motion (ROM), particularly involving lumbar lordosis, have been associated with increased low back pain (LBP). However it is not known how changing from RFS to FFS affects lumbar lordosis or LBP. Thus, the purpose of this study was to determine if a change from RFS to FFS would change lumbar lordosis, and/or decrease shock attenuation, and/or change comfort levels in healthy recreational/experienced runners.

Examining Lower Extremity Range Of Motion And Movement Variability Chages Due To Focus Of Attention During Landing, Andrew Nordin, Janet Dufek

Interdisciplinary Research Scholarship Day

Attentional focus (AF) has been explored among a variety of motor skills providing evidence that external AF promotes automaticity and enhanced performance [6]. External focus of attention is distinguished from internal focus such that external focus is directed toward movement effect rather than body movements [6]. Movement variability provides a means of assessing functional characteristics of the neuromotor system, where normal functioning is suggested to occur within optimal limits, while excessively high or low movement variability is indicative of system dysfunction [2,4,5]. Additionally, the ability of the motor system to vary, or broadly distribute, internal loads is thought to reduce …

Osteochondritis Dissecans Development After Bone Contusion Of The Knee In The Skeletally Immature: A Case Series, Kevin G. Shea, John C. Jacobs Jr., Nathan L. Grimm, Ronald P. Pfeiffer

Kinesiology Faculty Publications and Presentations

Osteochondritis dissecans (OCD) is thought to be an acquired osteochondral disorder, and its etiology may be multi-factorial. Trauma, both acute and repetitive events, has previously been proposed as a potential cause for OCD development. We present two cases of skeletally immature males who developed a symptomatic OCD lesion following a femoral condyle bone contusion. These cases suggest that an acute traumatic event may lead to the development of OCD of the knee.

Parkinson's Disease And Forced Exercise In A Community Setting: A Feasibility Study, Alati Gagne, Sarabeth Makins, James Walrath

Research Posters

Parkinson’s disease is a neurodegenerative disorder that increases an individual’s fall risk. In recent studies, an 8-week tandem bike forced exercise program was effective in reducing overall Parkinsonian symptoms. The feasibility of a tandem bike forced exercise program in a community setting has not been studied previously, and no published study has evaluated balance and health outcomes after participation in a forced exercise program. This six week tandem bike forced exercise protocol, conducted in a community setting for individuals with Parkinson’s disease, aimed to assess the feasibility of such a protocol, and to assess resultant balance and health outcomes.

Reconsidering And Re-Conceptualizing Kinesiology, T. G. Johnson

Kinesiology Faculty Publications and Presentations

The purpose of this article is to delineate a more humanistic view of kinesiology by drawing on the rich, but often overlooked, phenomenology of movement literature (Arnold, 1979; Brown & Payne, 2009; Merleau-Ponty, 1962). Brown and Payne (2009) maintain that "phenomenology is a reaction against...the scientization of [kinesiology] that sees its conceptualization, contextualization, representation, and legitimation primarily as a science" (p. 423). By drawing on the work of Maurice Merleau-Ponty (1962) and Peter Arnold (1979), I argue that kinesiology is not only a scientific discipline charged with creating and disseminating scientifically-based knowledge, but also a field of study that encompasses …

Determining Intensity Levels Of Selected Wii Fit Activities In College Aged Individuals, Joshua D. Griese, Yong Gao, Lynda Ransdell, Shawn R. Simonson

Kinesiology Faculty Publications and Presentations

To determine intensity of Nintendo Wii Fit games using indirect calorimetry. Twenty-five college students completed Wii Fit activity sessions at two difficulty levels within aerobics, strength, and yoga categories. Resting metabolic rate and exercise VO₂ were measured and metabolic equivalents (METs) were calculated. Measured METs and calculated METs ranged from 2.30 ± .42 and 2.44 ± .38 for Yoga to 5.73 ± 1.36 and 6.04 ± 1.09 for aerobics, respectively. All selected Wii Fit activity intensities were significantly higher than resting, p < .001; aerobic and strength activities met the moderate intensity threshold (3 METs, p < .001), yoga activities did not (p < .005); aerobic and yoga activities of medium difficulty were more intense than the corresponding easy-rated activities (p < .005). There were no statistical differences between measured and calculated METs. Wii Fit has potential as an effective tool for helping college-age individuals increase their PA.
