Ultrasound Visual Biofeedback And Accent Modification: Effects On Consonant And Vowel Accuracy For Mandarin English Language Learners, Courtney Armstrong
Ultrasound Visual Biofeedback And Accent Modification: Effects On Consonant And Vowel Accuracy For Mandarin English Language Learners, Courtney Armstrong
Electronic Theses and Dissertations
The number of individuals in the United States who speak languages other than English continues to increase. With the increase of language diversity comes a potential rise in communication challenges for those who speak with non-mainstream American English accents as English language learners. A portion of these individuals may elect to seek accent modification services, perhaps due to decreased intelligibility or communication breakdowns. Thus, speech-language pathologists must research and provide effective techniques to enhance intelligibility of all American English speakers for optimal communication. Few approaches employ a variety of treatment methods to improve speech sound accuracy, naturalness and intelligibility to …

Fascicle Arrangement In College-Aged Athletes, Jacob Goodin
Electronic Theses and Dissertations
Purpose: To compare muscle architecture variables between sport and sex in competitive athletes, and to compare muscle architecture with performance variables in strong versus weak athletes, and good versus poor jumpers. Methods: The vastus lateralis (VL) and lateral gastrocnemius (LG) muscles of 139 collegiate athletes were collected using ultrasonography to determine muscle thickness (MT), pennation angle (PA), fascicle length (FL), and relative fascicle length (FLrel). Absolute and relative peak power, absolute and relative isometric peak force, and jump height were measured in a subset of baseball and soccer athletes. A 5x2 factorial analysis of variance (ANOVA) was used …
Acute And Chronic Vascular Responses To Blood Flow Restriction In The Upper Body, J. Grant Mouser
Acute And Chronic Vascular Responses To Blood Flow Restriction In The Upper Body, J. Grant Mouser
Electronic Theses and Dissertations
Blood flow restriction (BFR) with low load exercise increases muscular size and strength. Little is known of vascular adaptations to this training modality, and nothing was known at very low loads. These studies examined cardiovascular responses to high load (70% of one-repetition maximum (1RM)) and very low load (15%1RM) exercise, alone or at two levels of BFR. Study 1: Participants performed unilateral biceps curls using either 15%1RM with no BFR (15/00), 40% of arterial occlusion pressure (AOP) (15/40), or 80%AOP (15/80), or 70%1RM (70/00). Systolic and diastolic blood pressure (SBP, DBP) and blood flow (BF) were measured in the arms …
