||The objectives of this study were to propose methodological strategies for analyzing vagal cardiac control based on the Stress Disequilibrium Theory (SDT) using high frequency power of heart rate variability (HFP) and short term variance of HFP, as well as to provide evidence of reduced vagal cardiac control range and variability in high strain job and exhausted subjects. Job strain was measured using the Job Content Questionnaire, diary reports and a standardized occupational code linkage in 36 healthy mid-aged males with varying strain jobs. Subjects were Holter-monitored for 48 hours, including a work and rest day. Comparisons were made between 10 high and 22 low job strain jobs. Furthermore, four subjects categorized as exhausted were analyzed separately. Findings support the hypothesis that job strain is associated with reductions in cardiac vagal variance, and that reduced system variability may be a characteristic of exhaustion.
