Ground Reaction Forces Through A Range Of Speeds In Steeplechase Hurdling, James Brian Tracy
Ground Reaction Forces Through A Range Of Speeds In Steeplechase Hurdling, James Brian Tracy
Theses and Dissertations
The men's steeplechase event requires participants to jump over thirty-five 0.914-meter-tall obstacles, 4 rigid barriers and 1 fixed barrier followed by a 3.66-meter-long water pit per lap, over a 3000-meter distance. This study investigated the effect of increasing running velocity, through a range of 5.33 m/s to 6.66 m/s, on takeoff and landing ground reaction forces, for males during steeplechase hurdling using a force plate embedded under a track surface. Subjects completed 1 trial within each of 6 different pace ranges in a random order, once with a hurdle following the force plate to measure the takeoff ground reaction forces …
The Effects Of Experimental Anterior Knee Pain On Bilateral Ground Reaction Forces During Running, Emily Rachel Cronk
The Effects Of Experimental Anterior Knee Pain On Bilateral Ground Reaction Forces During Running, Emily Rachel Cronk
Theses and Dissertations
The purpose of this study was to examine the independent effects of anterior knee pain (AKP) on bilateral ground reaction force (GRF) during running, with a focus on GRF applied to the uninvolved leg, which, prior to this study, had never been evaluated. Twelve volunteers completed three data collection sessions, that corresponded to one of three conditions (control, sham, and pain), in a counterbalanced order. For each session, subjects ran for five minutes. For the pain and sham sessions, respectively, hypertonic and isotonic saline were infused into the infrapatellar fat pad of the right leg during the running, while no …
Ground Reaction Forces Generated By Twenty-Eight Common Hatha Yoga Postures, Sylvia Joan Wilcox
Ground Reaction Forces Generated By Twenty-Eight Common Hatha Yoga Postures, Sylvia Joan Wilcox
Theses and Dissertations
Yoga adherents claim many benefits of the practice, including promotion of bone health and prevention of osteoporosis. However, few, if any, studies have investigated whether yoga enhances bone mineral density. Furthermore, none have identified force generation in yoga. The purpose of this study is to collect ground reaction force (GRF) data on a variety of common hatha yoga postures that would be practiced in fitness centers or private studios. Twelve female and eight male volunteers performed a sequence of 28 common hatha yoga postures while ground reaction force data were collected with an AMTI strain-gauge force plate. The sequence was …
