Interactions among behavioral style, ventilatory drive, and load recognition.
The American Review of Respiratory Disease

Summary
Behavioral style impacts breathing load recognition. Higher resting ventilatory drive (breathing effort) lowers the resistance needed for detection, especially in anxious individuals.
Area of Science:
- Respiratory Physiology
- Behavioral Neuroscience
- Psychophysiology
Background:
- Previous research linked behavioral styles to breathing load recognition.
- The underlying physiological mechanisms remained unclear.
Purpose of the Study:
- To investigate the relationship between resting ventilatory drive, behavioral style, and the perception of breathing resistance.
- To clarify the basis for behavioral influences on respiratory load detection.
Main Methods:
- Assessed resting ventilatory drive using inspiratory neuromuscular activity via mouth occlusion.
- Categorized 12 healthy subjects into behavioral style groups using the MMPI Panic-Fear Scale.
- Determined the threshold resistance for recognizing added inspiratory loads.
Main Results:
- A significant inverse correlation was found between resting ventilatory drive and the threshold resistance.
- Higher ventilatory drive correlated with a lower threshold resistance (easier detection).
- Anxious, dependent subjects exhibited lower ventilatory drive and required more resistance for detection compared to other groups.
Conclusions:
- Resting ventilatory drive level appears to influence the ability to detect added resistive loads during breathing.
- Behavioral style and resting ventilatory drive are interrelated, affecting respiratory perception.
