【 摘 要 】

Background: This study examines the impact of different mood states on exertional dyspnea during standard exercise stress test in healthy subjects.Methodology: 25 healthy subjects went through standard cycle ergometer exercise test on three separate days. On each day, subjects viewed randomly assigned images designed to induce positive, negative, or neutral mood states. For each condition, at minute intervals, subjects rated dyspnea (sensory and affective domains) in the first test and mood (valence and arousal domains) in the second test. Respiratory rate and heart rate were measured throughout the exercise.Results: In comparison to negative mood state, there was significant decrease in dyspnea [3.2(2.0-3.9) vs. 4.6(4.2-5.4)], botherness to dyspnea [3.2(2.2-3.8) vs. 4.6(4.0-5.8)], respiratory rate [29.0(26.3-31.6) vs. 32.2(29.7-35.3) cycles/min] and heart rate [114(102.7-138.7) vs. 123(109.9-144.3) beats/min] in positive mood state. Likewise, in comparison to neutral mood state, there was significant increase in dyspnea [4.6(4.2-5.4) vs. 3.4(3.0-3.8)], botherness to dyspnea [4.6(4.0-5.8) vs. 3.6(2.8-4.2)], respiratory rate [32.2(29.7-35.3) vs. 28.4(26.6-31.2) cycles/min] and heart rate [116.4 (105.4-128.4) vs. 123(109.9-144.3) beats/min] in negative mood state.Conclusion: The result suggests that negative mood state increase and positive mood state decrease perceived dyspnea. These findings can have profound impact via psychotherapeutic interventions on patients of cardiorespiratory diseases to reduce dyspnea.
