AB  - This study examines the acute effect of heart rate variability (HRV) biofeedback 
      on HRV measures during and immediately after biofeedback and during the following 
      laboratory-induced stress. Eighteen healthy males exposed to work-related stress 
      were randomised into an HRV biofeedback group (BIO) or a comparative group (COM). 
      Subjects completed a modified Stroop task before (Stroop 1) and after (Stroop 2) 
      the intervention. Both groups had similar physiological responses to stress in 
      Stroop 1. In Stroop 2, the COM group responded similarly to the way they did to 
      Stroop 1: respiratory frequency (RF) and heart rate (HR) increased, RMSSD and 
      high frequency (HF) power decreased or had a tendency to decrease, while low 
      frequency (LF) power showed no change. The BIO group responded differently in 
      Stroop 2: while RF increased and LF power decreased, HR, RMSSD and HF power 
      showed no change. In the BIO group, RMSSD was higher in Stroop 2 compared to 
      Stroop 1. In conclusion, HRV biofeedback induced a short term carry-over effect 
      during both the following rest period and laboratory-induced stress suggesting 
      maintained HF vagal modulation in the BIO group after the intervention, and 
      maintained LF vagal modulation in the COM group.
