Comparing Reaction Time And Postural Stabilization Based On Activity Groups In Older Adults, Lauren Marie Merk

Theses and Dissertations

The purpose of this study was to compare reaction time and postural stabilization between activity groups in older adults. These variables are important because older adults are at a high fall risk and two major contributors to fall risk are postural stabilization and reaction time. This study examined if the activity group of an older adult had any influence on reaction time and postural stabilization. Fifty-nine older adults aged 66.46 ± 9.47 years old were used in the study. Thirteen subjects were in the master’s athletes which are individuals over the age of 40 who competed in a ...

What You Know Makes A Difference: Physical Activity Maintenance And Adherence Of Collegiate Students, Vista Beasley, Brooke Thompson, Patrick R. Young, Itay Basevitch 2017 University of Stirling

What You Know Makes A Difference: Physical Activity Maintenance And Adherence Of Collegiate Students, Vista Beasley, Brooke Thompson, Patrick R. Young, Itay Basevitch

Journal of Counseling and Psychology

For decades, exercise psychology researchers dismissed health/exercise knowledge as a determinant of physical activity (PA). We sought to overturn this misconception, showing that psychological theory may serve as a basis for informing physical education curriculum. Based on social cognitive and self-determined motivation theories, we examined health/exercise knowledge as a determinant of collegiate students’ PA maintenance (i.e., ≥ 6 months of regular PA involvement); adherence to United States Department of Health and Human Services (USDHHS) 2008 PA guidelines; and PA types (i.e., aerobic, weight training). Collegiate students (n = 231) provided data via online survey. ANOVA analyses revealed that ...

Exploring The Utilisation Of Stand Up Paddle Boarding In Australia, Ben Schram, James Furness

James Furness

Stand Up Paddle Boarding (SUP) has grown exponentially in the last few years with unprecedented participation rates globally. Despite some scientific research on physiological and performance variables, minimal information exists regarding participation and utilisation. The purpose of this study was to discover more about how and where people participate in the relatively new sport of SUP. An open-source online survey application was administered internationally to active SUP participants to capture information relevant to both demographics and participation. Of a total of 240 responses, 154 (64.2%) were Australian. The average SUP rider was 42.9 ± 11.7 years, mass 80 ...

The Effects Of Moderate Intensity Strength Training Coupled With Blood Flow Restriction: A 12 Week Intervention, Kelly Barrett 2017 The University of Western Ontario

The Effects Of Moderate Intensity Strength Training Coupled With Blood Flow Restriction: A 12 Week Intervention, Kelly Barrett

Electronic Thesis and Dissertation Repository

Blood flow restriction training (BFRT) has been suggested to increase muscle size and strength in trained and untrained individuals when using light load intensities (30 percent 1-RM). However, there is little data to support its use when working with moderate load intensities, specifically, above 50 percent of an individual’s 1-RM. The purpose of this study was to evaluate the effects of moderate load intensity BFRT on muscle size and strength of the biceps brachii after a 12 week strength training intervention. Nine, previously strength trained, participants performed an elbow flexion exercise at 70 percent of their individualized 1-RM, twice ...


The Relationship Between Generalized Joint Laxity And Hip Cartilage Thickness In Ballet And Modern Dancers, Noelle Jeanette Tuttle 2017 Brigham Young University

The Relationship Between Generalized Joint Laxity And Hip Cartilage Thickness In Ballet And Modern Dancers, Noelle Jeanette Tuttle

All Theses and Dissertations

Generalized joint laxity (GJL), a condition in which most joints of the body move beyond the accepted normal range of motion, is present in many ballet and modern dancers. It has been associated with an increased risk of injury, decreased muscle strength, and greater landing forces. Increased joint laxity results in joint instability and may precede the development of osteoarthritis, which is associated with a reduction in cartilage thickness. We hypothesized that dancers with GJL would have decreased hip cartilage thickness, as well as greater hip adduction angles and greater ground reaction force on landings. Twenty female ballet and modern ...
