UNLV Theses, Dissertations, Professional Papers, and Capstones
When comparing oral breathing versus nasal breathing more volume of air can be transported through the oral passageway, but nasal breathing can lead to slower respiration rates and cleaner inspired air. The purpose of this study is to find the most efficient mode of breathing during different intensities of submaximal aerobic exercise. There were 9 males and 10 females that completed this study. First test was a VO2 Max test, 3.0 mph for 3 minutes, with increases in 1.0 mph every minute after that. Using a regression equation running speeds were determined for each individual’s submaximal intensities. The desire …

Pulmonary Diffusing Capacity Is Unaltered In Elite Swimmers After Restricted Breathing Training., Benjamin Todd Ogle 1990-
Electronic Theses and Dissertations
Controlled frequency breath (CFB) holding is a swim training modality that involves holding one’s breath for ~12 strokes before taking another breath. We looked to examine the effects of CFB training on pulmonary diffusing capacity for nitric oxide (DLNO) and carbon monoxide (DLCO). Elite swimmers (n = 25) were divided into either the CFB or a group that breathed regularly, every ~3rd stroke. The training intervention included 16 sessions of 12 x 50-m repetitions with either breathing pattern. Approximately 60% of the males and ~20% of the females were above the upper limits of normal for diffusing capacity at baseline. …

A high prevalence of sleep-disordered breathing (SDB) after spinal cord injury (SCI) has been reported in the literature; however, the underlying mechanisms are not well understood. My studies had 2 aims: 1) to determine the effect of the withdrawal of the wakefulness drive to breathe on the degree of hypoventilation in SCI patients and able-bodied controls and 2) to determine the response of …
