The Relationship Between Feeding Type And Temporomandibular Joint Morphology In Superfamily Musteloidea, Travis L. Garvin
The Relationship Between Feeding Type And Temporomandibular Joint Morphology In Superfamily Musteloidea, Travis L. Garvin
Masters Theses
Many studies have focused on the soft tissue analysis of carnivores and have demonstrated a relationship between feeding biomechanics and feeding types. Herbivores and omnivores rely heavily on anteroposterior and helical movement of the mandible and teeth for the breakdown of fibrous foods resulting in a flat mandibular fossa while the function of the carnivore TMJ is different, as they need a much stable joint for ripping and tearing of the flesh. I aim to look at whether the bony morphology of the temporomandibular joint (TMJ) can be directly related to feeding type, specifically in the superfamily Musteloidea. I sampled …
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 …
The Effects Of Desoxycorticosterone, Hydrocortisone, And Prednisone On Myogenesis In Vitro, Gregory K. Nienaber
The Effects Of Desoxycorticosterone, Hydrocortisone, And Prednisone On Myogenesis In Vitro, Gregory K. Nienaber
Masters Theses
In order to obtain proper muscle development in tissue culture, certain conditions must prevail. There is a delicate balance of factors, and elimination of even one of these factors leads to poor and improper development. Muscle cells grown in the absence of fibroblasts usually fail to differentiate. Therefore, proper development depends upon the presence of two cell types: myoblasts and fibroblasts. Investigators have demonstrated that the fibroblasts are necessary in that they produce collagen which is necessary for proper muscle development. The present study has shown that desoxycorticosterone, hydrocortisone, and prednisone at concentrations of 10, 1, and 0.1 ug/ml of …
