A Review Of Literature For Osteology: Cell Biology, Tissue Biology, And The Application Of Synthetic Compounds For The Facilitation Of Bone Tissue Repair, Ryan T. Jones
Honors Theses
Bone is a dynamic matter that provides support, structure, mineral reserves, and stem cell reserves for the body. Important functions range from structural support for the body to roles in maintaining homeostasis. Structure and support for the body is the most obvious role, with the skeletal system as a whole providing a normal force for other tissues and organs to resist gravity. Protection is also inferred for tissues and organs from impacting forces, especially with axial bones covering vital organs in the thoracic cavity. Another function of bone includes the ability to store and release minerals when needed to maintain …
The Effects Of Differing Bicycle Frame Geometry On Muscle Recruitment Strategies And Power During A 30-Second Wingate Anaerobic Test, Patrick Hills-Meyer
The Effects Of Differing Bicycle Frame Geometry On Muscle Recruitment Strategies And Power During A 30-Second Wingate Anaerobic Test, Patrick Hills-Meyer
Masters Theses
The purpose of this study was to test how changing the bicycle frame geometry; from a shallow frame geometry [seat tube angle (STA) of 72°] to a steep frame geometry (STA of 82°) affected the electromyographic (EMG) signal of the hamstrings [biceps femoris (BF) and semitendinosus (ST) muscles] and the quadriceps [vastus medialis (VM) and vastus lateralis (VL)] and power (max, mean, min, and, % drop) during a Wingate anaerobic test (WAT). To measure the muscle recruitment and power, 12 experienced triathletes were prepped with surface electrodes to measure EMG amplitude and an electrogoniometer to measure knee joint angle while …
A Kinematic And Kinetic Analysis Of First, Fourth, And Fifth Positions In The Classical Ballet Method, Mary Sue Hill
A Kinematic And Kinetic Analysis Of First, Fourth, And Fifth Positions In The Classical Ballet Method, Mary Sue Hill
Masters Theses
The problem of the study was to compare electromyography (EMG) responses, ground reaction forces, and torques on female college-age dancers' knees in selected positions. Subjects were 18 female dancers, aged 18 to 30 years, with 6 subjects from each of three levels: Ballet Technique I, II, and III. The rectus femoris, vastus lateralis, and vastus medialis were analyzed in a grande plie in three positions, (1) first, (2) fourth, and (3) fifth, with two phases: (1) eccentric, and (2) concentric. No differences in force or EMG data were found for the concentric phases of the three positions. Significant differences were …
Pain Levels And Rating Of Perceived Exertion Of People With Herniated Lumbar Disc While Walking In Two Environments, Brenda L. Cunningham-Boerger
Pain Levels And Rating Of Perceived Exertion Of People With Herniated Lumbar Disc While Walking In Two Environments, Brenda L. Cunningham-Boerger
Masters Theses
The purpose of the study was to investigate if walking in water is an effective substitute for walking on land as an aerobic exercise for people with herniated lumbar disc. The study involved the dependent variables o f perceived pain levels (PPL) and ratings o f perceived exertion (RPE). Independent variables were walking condition and work intensity. Land walking was performed on a treadmill; water walking was performed in an indoor pool 4.5 ft deep and 90*F. Work was set at four different intensities, based on the formula for predicting maximum heart rate (MHR), 220 minus age. The graded work …
