Exploring How Gentrification-Related Effects Impact The Health Of Older Black Adults, Ann Wachana, Holly Hinson
Exploring How Gentrification-Related Effects Impact The Health Of Older Black Adults, Ann Wachana, Holly Hinson
McNair Symposium
Black adults living in gentrifying neighborhoods experience cultural incongruence with new, often younger, high SES and White residents. In addition, older Black adults are losing deep ties to their neighborhood. This is a major loss to their social network and their sense of belonging within their own neighborhoods. Disruption of long-standing social ties can cause changes in mental health and raises concerns about gentrification’s potentially disruptive impact on cognitive health and the brain aging process. In order to learn more about the experience of older Black adults within a rapidly changing city, focus group discussions from the Sharing History through …
The Effects Of Quadmill Training On Balance: An Intervention Study 2017, Alexander J. Generali
The Effects Of Quadmill Training On Balance: An Intervention Study 2017, Alexander J. Generali
Master's Theses
The purpose of this study was to observe and compare the effects of two separate training interventions using the QuadmillTM to a control group on balance in college-aged individuals. It was hypothesized that both experimental groups (I1 and I2) would experience improvements in balance over the intervention whereas the control group would remain at baseline. It was secondarily hypothesized that I2 would experience greater improvements than I1 in balance due to the nature of the exercise protocol. Data was collected using three systems; Balance Tracking Systems, Star Excursion Balance Test, and the Biodex Balance system. A two-way mixed methods ANOVA …
Using Cultural Relevancy To Promote African American Brain Health, Miya Walker
Using Cultural Relevancy To Promote African American Brain Health, Miya Walker
University Honors Theses
African Americans are disproportionately more likely than older whites to develop Alzheimer’s disease and other dementias (ADOD). Despite these disparities, there is difficulty in motivating African Americans to engage in activities suitable to maintaining cognitive health (walking, social engagement, physical activity). The Sharing History through Active Reminiscence and Photo-imagery (SHARP) walking program (Croff, PI) combines these proactive activities in a culturally relevant way to create a motivational force to preserve cognitive health. SHARP engaged 19 African Americans aged 55 and older on 72 themed, 1-mile walks over 6 months in Portland, Oregon’s historically Black neighborhoods. This study examines participant responses …

Theses : Honours
The purpose or this study was to test the suitability or selected assistance exercises to strengthen the low back for the Olympic lilts in elite weightlifters. Four subjects were filmed by a five-camera Motion Analysis system operating at 120Hz. The subjects completed both or the Olympic lifts (Snatch and Clean) at a near one repetition maximum and four assistance exercises (Bent-over Row, Clean Pull Deadlift, Romanian Deadlift, and Good Morning) at an intensity typically performed at a routine training session. Peak moments, compressive and shear forces about the L5/S1 intervertebral joint were calculated via a top-down inverse dynamics model. Comparisons …
Sense Of Effort Associated With Exercise In The Chronic Fatigue Syndrome, Karen E. Wallman
Sense Of Effort Associated With Exercise In The Chronic Fatigue Syndrome, Karen E. Wallman
Theses : Honours
Investigations into the mediators of effort sensation have indicated that central mechanisms related to corollary discharges may be responsible for an increased sense of effort during fatiguing isometric exercise. The role for central mediators for sense of effort have been objectively demonstrated through use of contralateral limb matching tasks. Subjects diagnosed with chronic fatigue syndrome (CFS) often report prevalent fatigue associated with a greater sense of effort when involved in exercise. This study employed a fatiguing contralateral limb-matching task in order to determine if CFS subjects (n == 6) experienced an altered sense of effort associated with the task when …

Changes In Muscular Power Associated With Delayed Onset Muscle Soreness, Carmel Nottle
Theses : Honours
The aims of the this study were to investigate the effects of delayed onset muscle soreness (DOMS) following downhill running on cycling power output and to determine the extent of any relationships between power output, strength, and DOMS. 12 active male subjects (aged 18-25 years) were randomly assigned to either a test (n=7) or control (n=5) group. The test group performed a 5 x 8 minute downhill running protocol at a grade of -7% and a speed corresponding to 80% of the subjects age predicted heart rate maximum. Measurements of isometric knee extension and flexion strength, peak and average cycling …
The Perception Of Effort During Muscular Fatigue And Recovery, Juan H. Svendsen
The Perception Of Effort During Muscular Fatigue And Recovery, Juan H. Svendsen
Theses : Honours
This study investigated how sense of effort is altered during fatigue in nine normal subjects. A contralateral limb matching paradigm was used in which the subjects nondominant (reference) arm was held at 20% MVC with force production matched at one minute intervals by the dominant (marching arm). It was found that matching force increased in a linear fashion with fatigue. It was also observed that EMG amplitude increased in the reference and matching arm and remained elevated during a 15 minute recovery period. As in previous studies strong correlation (r = 0.85) between rmsEMG in the reference arm and matching …
The Effect Of Eccentric And Concentric Training On The Size And Strength Of Human Skeletal Muscle, Haydn J. N. Mcdonald
The Effect Of Eccentric And Concentric Training On The Size And Strength Of Human Skeletal Muscle, Haydn J. N. Mcdonald
Theses : Honours
The objective of this study was to determine if the high forces generated through eccentric contractions, and the subsequent damage sustained, contributes to greater growth and force increase in human skeletal muscle than other contraction types, and whether damage from eccentric exercise effects the increase in torque and muscle size expected after a progressive concentric strength training program. 20 healthy subjects were split into four groups which participated in 3 different training protocols, with one group serving as the control (C). Groups underwent either concentric training (CT), eccentric damage (ED), or a combination of the two protocols (DC) with the …
Eccentrically Induced Skeletal Muscle Damage In Patients With Chronic Fatigue Syndrome (Cfs), With Reference To Overtrained Athletes, David L. Wright
Eccentrically Induced Skeletal Muscle Damage In Patients With Chronic Fatigue Syndrome (Cfs), With Reference To Overtrained Athletes, David L. Wright
Theses : Honours
Chronic fatigue syndrome (CFS) and Overtraining syndrome (OTS) are separate, complex conditions which have so many similar debilitating effects that it has led some researchers to conclude that OTS is a sub-condition of CFS. The purpose of this research was to compare the force and damage-recovery characteristics of skeletal muscle in CFS patients and control normals, after a single damaging bout of eccentric contractions in the non-dominant forearm flexors. The subjects ( n = 25 ), a convenience sample were assigned to three groups; [I] CFS + eccentric damage (n = 8), [2] Control Damage (CD)+ eccentric damage (n = …

Anuran Activity Energetics, Scott R. Landrey
Dissertations and Theses
This thesis presents two separate experiments concerning aerobic and anaerobic amphibian energetics. The first study (Part I) investigates differential alterations in the kinetics of the anaerobic enzyme lactate dehydrogenase, in nine species of anurans with varying natural histories. The second study (Part II) studies changes in different anaerobic and aerobic physiological parameters in a single species (Rana catesbeiana) after six weeks of chronic exercised, unexercised-captive and for field frogs. The common theme of these two experiments involves the potential for physiological changes due to environmental stress. Part I examines different species to infer a possible evolutionary relationship to …
