The Short-Term Effect Of Whole Body Vibration Training On Sprint Start Performance In Collegiate Athletes, J. Brent Feland, J. Ty Hopkins, Iain Hunter, Brad Roberts

Faculty Publications

Whole body vibration (WBV) is characterized by a vibratory stimulus emitted throughout the body through the use of a vibrating platform on which the subject stands. Studies have shown over 30% increases in maximal explosive strength such as maximal speed biceps curl as well as increases in maximum dynamic force such as maximal sitting bench pull as the result of vibration. The purpose of this study was to investigate the effects of short term whole-body vibration on sprint starts among collegiate track athletes. On the first day eleven subjects were randomly assigned to either a non-vibration or vibration group for …

The Influence Of Concurrent Visual Feedback During Treadmill Training In Parkinson’S Disease, Rose Ellen Johnston

Theses and Dissertations (Comprehensive)

Walking is an exercise that has been thought to benefit Parkinson’s disease (PD). In a laboratory setting treadmills have been employed to successfully improve certain aspects of gait in PD (Cakit et al., 2007, Fisher et al., 2008, Herman et al., 2007, Miyai et al., 2000, Miyai et al., 2002, Pohl et al., 2003). Research has also indicated that walking with visual cues can improve aspects of gait that are impaired in PD (Azulay et al., 1999, Bagely et al., 1997, Nieuwboer et al., 2007), however, the integration of visual cues and treadmill training has yet to be studied. Thus, …

Effects Of Estrogen Receptor Activation On Post-Exercise Muscle Satellite Cell Proliferation, Kareem Bunyan

Theses and Dissertations (Comprehensive)

This study investigated the role of estrogen receptor activation on total and proliferating satellite cells following running exercise in rats, by using an estrogen receptor-alpha (ER-α) specific agonist, 4,4,4 (4-Propyl-[1H]-pyrazole-1,3,5-triyl) trisphenol (PPT). PPT is the first ER-α specific agonist (Stauffer et al 2000) which binds the ER-a subtype with a 410-greater affinity than ER-β (Stauffer et al 2000). Previous studies have demonstrated that estrogen can augment muscle satellite cell numbers following exercise (Enns and Tiidus, 2008) and that this augmentation may be due to mechanisms activated via estrogen receptors that can influence total, proliferating, and differentiating satellite cell numbers (Enns …

Piecing Together The Puzzle Of Autism: Aspects Of Its Effects On Children With The Condition And Their Caregivers, Roula Markoulakis

Theses and Dissertations (Comprehensive)

As one of the most prevalent developmental disorders, extensive research exists concerning Autism Spectrum Disorders (ASD). However, gaps are still evident in a number of areas. Information pertaining to any costs and benefits associated with the experience of caring for a child with autism is inadequate. In Study 1, the lived experiences of married female primary caregivers of children with autism were explored, specifically by examining the costs and benefits of caregiving and its influence on the women’s situations. Furthermore, motor control deficits are apparent in many children with high functioning autism (HFA) and Asperger syndrome (AS), but need to …

An Examination Of Intercollegiate Athletic Injury Tracking Systems Within Canadian Universities, Andrew D. Ross

Theses and Dissertations (Comprehensive)

Information regarding the practice of athletic injury tracking within Canadian intercollegiate institutions has been relatively deficient. The study aimed to assess the current status of athletic injury tracking systems (AITS) in Canadian universities within the Canadian Interuniversity Sport Association (CIS). A secondary purpose was to obtain data from therapists within Canadian Universities, to identify and analyze issues, benefits, barriers and obtain information regarding how athletic injury tracking methods are conducted. This was achieved by obtaining data regarding the current state of AITS in CIS institutions, clinical demographics, athletic therapists and/or physiotherapists’ opinions regarding the pro’s and con’s of athletic injury …

The Relationship Between Socioeconomic Status And Physical Activity Among Adolescents, Meredith Laurel Stockie

Theses and Dissertations (Comprehensive)

Background: Many Canadian youth are inactive (Active Healthy Kids Canada, 2009). Socioeconomic status (SES) is one factor that influences youth physical activity (PA) levels; however, the factors involved in this relationship are not well understood. Given that numerous quantitative studies suggest there is a positive relationship between SES and PA among adolescents, but offer little insight into why the given relationship exists, the purpose of the current thesis is to study the factors that influence the relationship between SES and PA among youth aged 12–14 years through a qualitative lens.

Methods: Low (n = 2) and high SES (n = …

The Influence Of Propyl Pyrazole Triol On The Post-Exercise Alpha Estrogen Receptor-Mediated Activation Of Satellite Cells In Skeletal Muscle Of Ovariectomized Rats, Amy Elisabeth Thomas

Theses and Dissertations (Comprehensive)

Estrogen has been shown to augment satellite cell activation, proliferation and total number and that this may occur through an estrogen receptor (ER) mediated mechanism. The purpose of this study was to investigate the role of ERs in the postexercise estrogen-induced augmentation of satellite cells in skeletal muscle of ovariectomized rats. Furthermore, the specific role of the ERα was examined through the use of an ERa agonist, propyl pyrazole triol (PPT). Ovariectomized rats were used (n=64) and separated into 4 groups: sham, estrogen supplemented, agonist supplemented and a combined estrogen and agonist supplemented group. These groups were further subdivided into …

Quantifying The Onset Of The Concentric Phase Of The Force–Time Record During Jumping, S.K. Leissring, William Ebben, Luke Garceau, Erich Petushek, R.L. Jensen

Exercise Science Faculty Research and Publications

Thirteen college students performed a drop jump from height equal to their peak vertical jump, single leg jumps from the left and right legs, and a counter movement jump. Vertical ground reaction force (GRF) obtained via an AMTI force plate and video analysis of markers placed on the hip, knee, lateral malleolus, and fifth metatarsal were used to estimate reaction forces on the knee joint. One-way Repeated Measures ANOVA indicated no differences for knee joint reaction forces relative to body weight or peak GRF for any of the jumps (p > 0.05). Average measures Intraclass Correlation Coefficients ranged from r = …
