Dental Hygiene Theses & Dissertations
Purpose: Physiological symptoms and comfort levels while wearing an N95 respiratory mask has not been examined with dental hygienists. The purpose of this study was to investigate dental hygiene students reported physiological symptoms and comfort perception while wearing an N95 respirator mask during patient care appointments. Methods: After IRB approval (IRB #1987754-2), a 16-item questionnaire was distributed through email to a convenience sample of 65 dental hygiene students. Questions assessed respiratory, dermatologic, cardiac, mask mouth and general physiological symptoms, as well as comfort levels. Additionally, participants were asked to respond to demographic questions and one open ended question inquiring about …

Effect Of Acute Caffeine Ingestion On On-Field Performance In Division 1 Female Field Hockey Players, Nicole Danielle Fredricks
Human Movement Sciences & Special Education Theses & Dissertations
This study aimed to determine the effects of acute caffeine ingestion on on-field performance in collegiate female field hockey players. A placebo-controlled, double-blind, randomized, crossover experimental design was utilized. The participants (N=10) were female division 1 field hockey players (age: 20.0 ± 1.6 years). They competed in two 60-minute, off-season scrimmages separated by two weeks. They were randomly assigned to ingest the caffeine, 3 mg/kg of body weight, or placebo treatment 60 minutes before each scrimmage. They wore a PLAYERTEK (Catapult, Australia) global positioning system (GPS) device to track their total distance, sprint distances, power plays, and zone three and …
Effects Of Chewing Time On Gastrointestinal Discomfort, Substrate Use, And Performance During Running, Thomas Geaney
Effects Of Chewing Time On Gastrointestinal Discomfort, Substrate Use, And Performance During Running, Thomas Geaney
Human Movement Sciences & Special Education Theses & Dissertations
Previous research has shown that food particle size affects gastric processing. For example, food particles greater than 3 mm may delay gastric emptying under certain conditions. Delays in gastric emptying can be problematic during aerobic exercise, leading to nausea, bloating, fullness, and other gastrointestinal (GI) symptoms. In some cases, symptoms can be severe enough to negatively affect athletic performance. This study investigated the effects of manipulating chewing duration of carbohydrate sports bars on GI discomfort, physiological responses, and performance during endurance running. This crossover study recruited 12 male runners (age: 36.4 ± 7.2 years, VO2peak: 57.2 ± 4.7 …
