研究概览
简要总结
Teachers are a population at high risk for voice disorders given their occupational demands. In a teaching career, a common debilitating symptom among all vocal symptoms experienced is - vocal fatigue, impacting teachers' occupational performance and increasing health care costs. It is therefore essential to identify potential treatment options to alleviate the symptom of vocal fatigue. The purpose of this study is to utilize a body-system level cardiovascular training protocol in comparison to traditional voice production training to alleviate the symptoms of vocal fatigue.

结局指标
主要结局
Changes in Global Rating of Vocal Fatigue (VAS 100mm)
时间窗: At baseline, at 4 weeks after treatment
Global Rating of Vocal Fatigue (VAS 100mm) measures the ability to sustain voice with no fatigue at the end of a working day
Changes in Physiologic Cost of Speaking
时间窗: At baseline, at 4 weeks after treatment
Physiologic Cost of Speaking is measured as the rate of oxygen consumption at steady state/ rate of speech (wpm) for each of the two reading tasks
Changes in Post Task Physiological Recovery
时间窗: At baseline, at 4 weeks after treatment
Post Task Physiological Recovery is measured as the time, seconds, to reach baseline of oxygen consumption post task (within 0.2ml/kg/min) following each of the reading tasks
Changes in Vocal Fatigue Index (VFI)
时间窗: At baseline, at 4 weeks after treatment
Vocal Fatigue Index (VFI) is a retrospective scale that measures self-reported symptoms of vocal fatigue
Changes in Oxygen Uptake Kinetics
时间窗: At baseline, at 4 weeks after treatment
Oxygen Uptake Kinetics is measured as the pattern of oxygen use during each of the two reading tasks
Changes in Excess Post Exercise Consumption (EPOC)
时间窗: At baseline, at 4 weeks after treatment
EPOC is measured as the magnitude of recovery oxygen consumption, ml/kg/min for each of the reading tasks
Changes in Ratings of Perceived Exertion (RPE)
时间窗: At baseline, at 4 weeks after treatment
Borg Scale of Ratings of Perceived Exertion (RPE)- measures the self-report of vocal effort for each of the reading tasks
