We evaluated the experimental hypothesis that an acute bout of aerobic exercise (AE) serves as a buffer to psychosocial stress responses in low to moderate physically fit women. Forty-eight (24 White, 24 Black) 25- to 40-year-old women participated in two counterbalanced experimental conditions: an attention control and a 40-min bout of AE at 70% heart rate (HR) reserve. The attention control and AE treatments were followed by (a) 30 min of quiet rest, (b) exposure to mental and interpersonal threat, and (c) 5 min of recovery. Blood pressure (BP) and HR were monitored at baseline, during the stressors, and throughout recovery. Self-reported distress was assessed before each stressor and upon completion of the recovery period. The results provided clear evidence that exercise dampens BP reactivity to psychosocial stress. Additionally, compared with the attention placebo control, AE reduced both the frequency and intensity of anxiety-related thoughts that occur in anticipation of interpersonal threat and challenge.
一次急性有氧运动(AE)可作为一种缓冲,减轻身体状况为低到中度的女性的心理社会应激反应。48名(24名白人、24名黑人)25至40岁的女性参与了两种平衡的实验条件:注意力控制组和一次持续40分钟、心率(HR)储备为70%的急性有氧运动。注意力控制组和急性有氧运动组在之后均经历了:(a)30分钟的安静休息,(b)暴露于心理和人际威胁中,以及(c)5分钟的恢复期。在基线、应激源期间以及整个恢复期监测血压(BP)和心率。在每个应激源之前和恢复期结束时评估自我报告的痛苦程度。结果提供了明确的证据,表明运动可减轻血压对心理社会应激的反应性。此外,与注意力安慰剂对照组相比,急性有氧运动减少了在预期人际威胁和挑战时出现的焦虑相关想法的频率和强度。
