A Pilot Study Examining Exercise Self-Efficacy As A Mediator For Walking Behavior In College-Age Women, Lynne L. Ornes, Lynda B. Ransdell

Kinesiology Faculty Publications and Presentations

Since mechanisms of behavior change are not always evaluated in physical activity interventions, current interventions are limited until these mechanisms are better understood (Bauman, Sallis, Dzewaltowski, & Owen, 2002). Therefore, studies are needed that examine mediating variables, derived from theory, in the design, implementation, and evaluation of interventions. A mediator is a variable that must be included in an intervention in order for a specific change in a dependent variable or outcome to occur (MacKinnon, 2008). MacKinnon (2008) describes several methods of identifying mediators using statistical procedures, including the causal inference approach, difference in coefficients, product of coefficients, structural equation …

The Effects Of Aquatic Exercise On Physiological And Biomechanical Responses, Matthew M. Denning

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Due to recent advances in aquatic research, technology, and facilities, many modes of aquatic therapy now exist. These aquatic modes assist individuals (e.g., osteoarthritis patients) in the performance of activities that may be too difficult to complete on land. However, the biomechanical requirements of each aquatic therapy mode may elicit different physiological and functional responses. Therefore, the purpose of this thesis was to: (a) provide a review of the physiological and biomechanical differences between aquatic and land based exercises, and (b) examine the acute effects of underwater and land treadmill exercise on oxygen consumption (VO₂), rating of perceived …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purposes of these studies were to determine if an acute static stretch influenced isokinetic peak torque (IPT), and to examine if the order in which the warm up routine was performed affected peak knee extension torque. Twenty trained college male students performed maximal isokinetic knee extensions under four conditions: a control consisting of no stretching, a stretch only trial, jog then stretch, and stretch then jog conditions. Each stretch was held for a total volume of 360 s. Measurements were taken on a Biodex System 3 isokinetic dynamometer at speeds of 60º s^-1 and 300º s^-1. …

Women Bound To Be Active (Year 3 & 4): Can A Book Club Help Women Overcome Barriers To Physical Activity And Improve Self-Worth?, Jennifer L. Huberty, Jamie Vener, Lynda Ransdell, Laura Schulte, Melissa A. Budd, Yong Gao

Kinesiology Faculty Publications and Presentations

Little progress has been made toward increasing physical activity (PA) in women. This study aimed to determine if an 8-month theory-based book club intervention (Women Bound to Be Active) was effective in increasing: (a) self-worth, (b) benefits relative to barriers to PA, and (c) PA in women (n=51). Findings suggested a book-club was effective for improving: self-worth, the benefits relative to barriers to PA, and possibly participation in PA. This is an innovative model to help women become more active and learn skills that may enable them to be active on their own long after a PA program has ended.

The Effects Of Whole Body Vibration On Bone Mineral Density For A Person With A Spinal Cord Injury: A Case Study, Ronald Davis, Charlotte Sanborn, David Nichols, David M. Bazett-Jones, Eric Dugan

Kinesiology Faculty Publications and Presentations

Bone mineral density (BMD) loss is a medical concern for individuals with spinal cord injury (SCI). Concerns related to osteoporosis have lead researchers to use various interventions to address BMD loss within this population. Whole body vibration (WBV) has been reported to improve BMD for postmenopausal women and suggested for SCI. The purpose of this case study was to identify the effects of WBV on BMD for an individual with SCI. There were three progressive phases (standing only, partial standing, and combined stand with vibration), each lasting 10 weeks. Using the least significant change calculation, significant positive changes in BMD …

Women Bound To Be Active: One Year Follow-Up To An Innovative Pilot Intervention To Increase Physical Activity And Self-Worth In Women, Jennifer L. Huberty, Jamie Vener, Laura Schulte, Sara M. Roberts, Beth Stevens, Lynda Ransdell

Kinesiology Faculty Publications and Presentations

The purpose of this investigation was to assess the effectiveness of a lifestyle intervention (a women’s book club; Women Bound to be Active) in promoting long-term physical activity (PA). Thirty-five women (26-70 years; mean age 50.6 years) completed the 8-month intervention and participated in the one-year follow-up. At follow-up, PA returned to baseline levels; however, self-worth and body mass index significantly improved. Women were more knowledgeable about PA at follow-up; however, they failed to maintain PA after the intervention. Components of the intervention were effective in improving self-worth and lowering BMI at one-year follow-up. To enhance long-term PA adherence continued …

Kinesiology Faculty Publications and Presentations

Increasing physical activity (PA) has become a national health objective due to its associated health benefits, but low participation rates. Therefore, the purpose of this study was to determine the feasibility of an 8-month (September 2006 - April 2007) PA book club (Women Bound to Be Active-WBA) in increasing PA and self-worth (SW) among women. Fifty-six adult women participated in an 8-month intervention consisting of weekly meetings designed to improve PA knowledge, awareness, confidence, and SW. Results indicated a significant increase in PA and SW. The WBA program represents a creative theory-based approach to empowering women to be more active.

Functional Rehabilitation: Managing Low Back Pain Through Activities-Of-Daily-Living Education, Timothy E. Speicher, R. Daniel Martin, Robert M. Desimone

All PTHMS Faculty Publications

After trauma to the low back, a decrease in intervertebral joint stiffness can occur, which can lead to inability of the motor-control system to compensate for the tasks imposed on the tissues, resulting in spinal instability. Intervertebral joint stiffness can be thought of as a tightening of a corset around a spine segment, facilitated through coactivation of small and large spinal muscles. The motor-control system might be able to adapt initially with cocontractions of the intrinsic muscles, but an unbalanced demand between the small and large muscles can lead to muscle fatigue and poor task performance. The inability of the …

Sight-Reading Versus Repertoire Performance On The Piano: A Case Study Using High-Speed Motion Analysis, Brenda Wristen, Sharon Evans, Nikolaos Stergiou

Health and Kinesiology Faculty Publications

This study was intended to examine whether differences exist in the motions employed by pianists when they are sightreading versus performing repertoire and to determine whether these differences can be c[uantified using high-speed motion capture technology. A secondary question of interest was whether or not an improvement in the efficiency of motion could be observed between two sight-reading trials of the same musical excerpt. This case study employed one subject and a six-camera digital infrared camera system to capture the motion of the pianist playing two trials of a repertoire piece and two trials of a sight-reading excerpt. Angular displacements …

Time To Task Failure Differs With Load Type When Old Adults Perform A Submaximal Fatiguing Contraction, Sandra K. Hunter, Ludovic Rochette, Ashley Critchlow, Roger M. Enoka

Exercise Science Faculty Research and Publications

Young adults exhibit a longer time to task failure when performing a submaximal isometric contraction by pushing against a force transducer (force task) than when supporting an equivalent inertial load (position task). The purpose of this study was to compare the time to failure for old adults when they performed a force task and a position task with the elbow flexor muscles. Eighteen old adults (72 ± 4 years) performed the force and position tasks at 20% maximal voluntary contraction (MVC) force until task failure. The time to task failure was briefer for the position task (10.6 ± 6.1 min) …

Gender-Specific Protection From Microvessel Rarefaction In Female Hypertensive Rats, Paula E. Papanek, Mark J. Rieder, Julian H. Lombard, Andrew S. Greene

Exercise Science Faculty Research and Publications

Epidemiologic studies reveal that women have a significantly lower age-adjusted morbidity and mortality from cardiovascular disease than men, suggesting that gender is a cardiovascular disease risk factor. The mechanism of the “gender protection” is unknown. In this study, we investigated the microvascular remodeling in reduced renal mass plus a high salt (4.0% NaCl) diet model of hypertension (RRM + HS). We hypothesized that women would be protected from the increase in blood pressure and from the microvascular rarefaction associated with RRM + HS hypertension. Studies were designed to determine whether female rats were less susceptible to changes in microvessel density …
