Muscle Activity Amplitudes And Co-Contraction During Stair Ambulation Following Anterior Cruciate Ligament Reconstruction, Michelle Hall, Catherine A. Stevermer, Jason C. Gillette

Jason C Gillette

The purpose of this study was to compare muscle activity amplitudes and co-contraction in those with anterior cruciate ligament (ACL) reconstruction to healthy controls during stair negotiation. Eighteen participants with unilateral ACL reconstruction and 17 healthy controls performed stair ascent and descent while surface electromyography was recorded from knee and hip musculature. During stair ascent, the ACL group displayed higher gluteus maximus activity (1–50% stance, p = 0.02), higher vastus lateralis:biceps femoris co-contraction (51–100% stance, p = 0.01), and higher vastus lateralis:vastus medialis co-contraction (51–100% stance, p = 0.05). During stair descent, the ACL group ...

Fall Risk In Sedentary, Recreationally Active, And Masters Athlete Older Adults, Felicia Elizabeth Squires

Theses and Dissertations

The purpose of this study was to examine whether different habitual activity levels may affect balance ability in older adults. Balance must be studied as poor balance increases likelihood of falls. This study examined activity levels in older adults and effect on balance ability. Fifty-nine older adults aged 66.5 ± 9.5 participated. Three groups were separated by physical activity level. First group had 13 masters athletes, older adults performing least 150 minutes of aerobic activity a week and competing in nationally sanctioned event within the last six months. Twenty-seven older adults comprised recreationally active group performing at least 150 ...


Effects Of Direction Time Constraints And Walking Speed On Turn Strategies And Gait Adaptations In Healthy Older And Young Adults, Dennis Torre 2017 Seton Hall University

Effects Of Direction Time Constraints And Walking Speed On Turn Strategies And Gait Adaptations In Healthy Older And Young Adults, Dennis Torre

Seton Hall University Dissertations and Theses (ETDs)

Hip fractures can be life-threatening, debilitating, and costly. The odds for hip fracture increases from impact of sideways falls. While turning has been strongly associated with hip fracture & sideways falls, the distinction between the risks for walking-turns as opposed to low-velocity in-place turning is not clear. The present study sought to fill a gap as previous research had not compared walking-turn performance in young & healthy older adults at low-fall risk within the same study and response-conditions of speed interacting with direction-cue time constraints. Spatial-temporal variables representative of AP braking/propulsion (i.e. stride-length & speed) & ML stability (left/right H-H BOS) were collected with the Gaitrite upon approach of a turning zone whose entrance width was just 73 cm; and turn-strategy categorical data for stable wide-BOS step-turns, biomechanically challenging narrow-BOS spin-turns, and combined subtypes of mixed-turns either of the “extra-step” variety representative of an AP stability/braking issue or “small-amplitude” variety representative of a ML stability/balance issue were captured on video. Mixed-ANOVA of gait measures for AP propulsion/braking revealed no age-group differences in speed despite a trend for less of a fast-pace increase in elderly stride-length, yet similar anticipatory ...


Utility Of The Living (Well Through) Intergenerational Fitness And Exercise Program As A County-Delivered Extension Program, Ashleigh J. Sowle, Sarah L. Francis, Jennifer A. Margrett, Warren D. Franke 2017 Iowa State University

Utility Of The Living (Well Through) Intergenerational Fitness And Exercise Program As A County-Delivered Extension Program, Ashleigh J. Sowle, Sarah L. Francis, Jennifer A. Margrett, Warren D. Franke

Warren D Franke

Rural-residing older adults are not participating in regular physical activity. Extension is in an excellent position to fill this programming void through transdisciplinary programming such as the Living (well through) Intergenerational Fitness and Exercise (LIFE) program. Qualitative evaluation was conducted to assess the LIFE program's utility as an Extension-delivered program. Nearly all LIFE program managers were satisfied with the program and were likely to recommend it to others. Best liked program features and attributes were the ready-to-use curriculum, corresponding training, and intergenerational and rural focuses. These results suggest that the LIFE program is viewed as appropriate for delivery by ...


Lessons And Challenges Of Trials Involving Ancillary Therapies For Parkinson’S Disease, Chris J. Hass, Elizabeth L. Stegemoller, Madeleine E. Hackney, Joe R. Nocera 2017 Iowa State University

Lessons And Challenges Of Trials Involving Ancillary Therapies For Parkinson’S Disease, Chris J. Hass, Elizabeth L. Stegemoller, Madeleine E. Hackney, Joe R. Nocera

Progressive impairment, particularly related to gait, postural control and cognitive decline, are not effectively treated by the current pharmacological and surgical management of Parkinson's disease (PD). This has led many patients and treating physicians to explore concomitant therapeutic modalities such as aerobic exercise, resistance training, physical therapy, massage, dance and music therapy, tai chi and others to aid in reducing symptomatology and improving patient quality of life.


Repetitive Finger Movement Performance Differs Among Parkinson’S Disease, Progressive Supranuclear Palsy, And Spinocerebellar Ataxia, Elizabeth L. Stegemoller, Jennifer Uzochukwu, Mark D. Tillman, Nikolaus R. McFarland, SH Subramony, Michael S. Okun, Chris J. Hass 2017 Iowa State University

Repetitive Finger Movement Performance Differs Among Parkinson’S Disease, Progressive Supranuclear Palsy, And Spinocerebellar Ataxia, Elizabeth L. Stegemoller, Jennifer Uzochukwu, Mark D. Tillman, Nikolaus R. Mcfarland, Sh Subramony, Michael S. Okun, Chris J. Hass

Elizabeth L. Stegemoller

Background Differentiating movement disorders is critical for appropriate treatment, prognosis, and for clinical trials. In clinical trials this is especially important as effects can be diluted by inclusion of inappropriately diagnosed participants. In early disease duration phases, disorders often have overlapping clinical features, such as impairments in repetitive finger movement, making diagnosis challenging. The purpose of this pilot study was to examine and compare repetitive finger movement performance in participants diagnosed with idiopathic Parkinson’s disease, Progressive Supranuclear Palsy, and spinocerebellar ataxias. Methods Participants completed an unconstrained index finger flexion/extension movement (i.e. finger tap) in time with an ...


Walking As Ontological Shifter: Thoughts In The Key Of Life, Bibi (Silvina) Calderaro 2017 The Graduate Center, City University of New York

Walking As Ontological Shifter: Thoughts In The Key Of Life, Bibi (Silvina) Calderaro

All Dissertations, Theses, and Capstone Projects

With walking as ontological shifter I pursue an alternative to the dominant modernist episteme that offers either/or onto-epistemologies of opposition and their reifying engagements. I propose this type of walking is an intentional turning towards a set of radical positions that, as integrative aesthetic and therapeutic practice, brings multiplicity and synchronicity to experience and being in an expanded sociality. This practice facilitates the conditions of possibility for recurring points of contact between the interiority perceived as ‘body’ and the exteriority perceived as ‘world.’ While making evident the self’s at once incoherence with it-self, it opens to a space ...

Daniel W. Russell

Background: Schools are the most frequent target for intervention programs aimed at preventing child obesity; however, the overall effectiveness of these programs has been limited. It has therefore been recommended that interventions target multiple ecological levels (community, family, school and individual) to have greater success in changing risk behaviors for obesity. This study examined the immediate and short-term, sustained effects of the Switch program, which targeted three behaviors (decreasing children's screen time, increasing fruit and vegetable consumption, and increasing physical activity) at three ecological levels (the family, school, and community). Methods: Participants were 1,323 children and their parents ...

The well-rounded development of the child, including physical, cognitive, emotional, and social health, may be the most efficient route to well-being and academic success. The primary goal was to investigate the feasibility of implementing a 12-week structured program of physical activity (PA) incorporating cognitive, social, and emotional elements in preschool. Additionally, this study, using a within-subject design, examined the acute effects of a PA session on classroom engagement and changes on perceived competence and peer acceptance from the first to the last week of the program.


Effect Of Activity Trackers And Text Messaging On Exercise, Fitness, And Physical Activity Self-Efficacy Of Middle School Students, Alison F. Pittman 2017 University of Texas at Tyler

Effect Of Activity Trackers And Text Messaging On Exercise, Fitness, And Physical Activity Self-Efficacy Of Middle School Students, Alison F. Pittman

Nursing Theses and Dissertations

A decrease in physical activity as children age is a contributing factor to the U.S. obesity epidemic. Middle school children are particularly vulnerable to sedentary activities. Activity trackers show promise as a means to motivate children and adults to increase physical activity (PA). This study examined the effect of a text messaging intervention and use of activity trackers with a companion social website on the body mass index (BMI), body fat percentage, physical fitness, and PA self-efficacy of middle school children. Children aged 11-14 (n=102) were randomly assigned to one of three groups for a 10-week intervention: activity ...


The Effect Of Two Learning Conditions On A Dancer's Technical Accuracy And Confidence In A Simulated Performance Setting, Avery K. Lux 2017 University of Wyoming

The Effect Of Two Learning Conditions On A Dancer's Technical Accuracy And Confidence In A Simulated Performance Setting, Avery K. Lux

Honors Theses AY 16/17

In dance classes, mirrors are used to help students see if they are using proper alignment and technique. Mirrors are used in the classroom, but are not used in performances. Performances usually take place on a stage, with stage lighting. The purpose of this study is to see if there is a notable impact on the technical accuracy and confidence of the dancer when learning dance with the mirror versus learning dance without the mirror. For this study, participants learned sequences with and without the mirror, and executed the sequences in a simulated performance setting. A faculty panel assessed the ...


Promoting Benefits Of Physical Activity Through Persuasive Communication, Priynka Patil 2017 The University of Western Ontario

Promoting Benefits Of Physical Activity Through Persuasive Communication, Priynka Patil

Electronic Thesis and Dissertation Repository

Inactivity early in life can lead to inactively later in life, which can result in negative outcomes. The primary purpose was to determine if gain- or loss-framed messages about physical activity would change the attitudes, intentions, and behaviours of students in the contemplation or preparation stage of the Transtheoretical model. The secondary purpose was to determine if framing the message in terms of the physical health benefits, appearance/social benefits, or mental health benefits (benefit condition) would change attitude, intention and behaviour. Undergraduate female students (N=60) between the ages of 18 and 36 were recruited from the university. The ...

The Effect Of A Pettlep Imagery Intervention-Based Pre-Performance Routine On Golfer's Short-Game Performance, Logan Baughman 2017 Georgia Southern University

The Effect Of A Pettlep Imagery Intervention-Based Pre-Performance Routine On Golfer's Short-Game Performance, Logan Baughman

Electronic Theses & Dissertations

Studies have suggested that imagery has a positive effect on performance in a variety of sports. The PETTLEP model (Holmes and Collins, 2001) includes the seven minimum elements sport psychologists incorporate into their imagery scripts. The PETTLEP model is the most comprehensive imagery model, thus providing the most functional equivalence. Golf is the interest of this study, with research stating that imagery has an overall positive impact on golf performance (Nicholls & Polman, 2005). However, studies involving the PETTLEP model have not been investigated thoroughly. There are several shots that have not been studied with the PETTLEP model, therefore this investigation ...

In part 1, participants performed three randomized 1/3-mile walking bouts at an intensity equivalent to 70% of their oxygen consumption at ventilatory threshold (VO2-at-VT). During these exercise bouts, individuals viewed 1) their favorite television program (FavTV), 2) a standardized nature program (NatTV) or 3) no-TV program (NoTV). A behavioral ...


Relationships Among Self-Efficacy, Implicit Associations, Motives And Exercise Behaviour, Alison Divine 2016 The University of Western Ontario

Relationships Among Self-Efficacy, Implicit Associations, Motives And Exercise Behaviour, Alison Divine

Electronic Thesis and Dissertation Repository

The general purpose of this dissertation was to examine how self-efficacy, explicit exercise motives and implicit automatic associations with exercise influence exercise behaviour of sedentary adults. This dissertation is divided into three manuscripts. The first manuscript examined how self-selection influences the decision to enrol in an exercise program as well as in self-efficacy, explicit motives and implicit associations. Additionally, manuscript one sought to understand the role of self-selection bias in the adoption and maintenance of exercise over six months. A total of 290 inactive adults aged 35-65 completed the Multidimensional Self-Efficacy for Exercise Scale (MSES; Rodgers, Wilson, Hall, Fraser, & Murray, 2008), two Go/No Go Association Tasks (GNATs; Nosek ...
