Relationships Between Muscle Characteristics And Step Outcomes In Young And Old Adults, Kareem Abubukker
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Background: Falls are a primary cause of mortality and morbidity in older adults. In an effort to assess falls, a number of studies have measured neurological, biomechanical, and neuromuscular function in relation to fall risk. Despite efforts, falls continue to affect the older adult population leading to subsequent impaired mobility and function. Multiple factors contribute to fall risk among older adults, however, a factor that has shown a consistent relationship with the prevalence of future falls is reduced muscle characteristics. Moreover, the ability to rapidly accelerate a limb, as captured by rate of power development (RPD), rate of velocity development …

Effects Of Foam Rolling On Range Of Motion And Vertical Jump Height, Giovanna Leone, Chad Smith
Honors Theses
Static stretching has been shown to elicit an acute improvement in range of motion (ROM) in both the contralateral and ipsilateral limb. However, static stretching has also been shown to impair performance. Foam rolling has been used in clinical settings as well as by the general population to increase ROM without impairing performance. To date, there is limited research evaluating the effect of foam rolling on the contralateral limb. Therefore, the purpose of this study was to explore the effect of foam rolling on ROM and single-leg drop jump performance in the foam rolled and non-foam rolled legs. The results …

Assessment Of Joint Kinetics In Elite Sprint Cyclists, Lynne Munro
Assessment Of Joint Kinetics In Elite Sprint Cyclists, Lynne Munro
Theses: Doctorates and Masters
Sprint cycling requires the production of explosive muscle power outputs up to very high pedalling rates. The ability to assess muscular function through the course of the sprint would aid training practices for high-level performers. Inverse dynamics provides a non-invasive means of estimating the net muscle actions acting across any joint contributing to movement. However, analysis of joint kinetics requires motion-capture techniques that present some unique challenges for cycling. This thesis presents three studies investigating the application of a custom-designed force pedal system to examine the joint kinetics of elite trained track sprint cyclists. To provide the basis for selecting …
