The effects of aerobic fitness on resistance to psychosocial stressors are reviewed. To unravel the inconsistent results in studies examining the relationship between aerobic fitness and psychosocial stress response, a meta-analysis was conducted. The results of 34 studies having 92 effect size estimates from 1,449 subjects were statistically combined to compare psychosocial stressor tasks and arousal measures. The average effect size estimate of 0.48 was significantly different from zero (P less than 0.01), indicating that aerobically fit subjects had a reduced psychosocial stress response compared to either control group or baseline values. The test for the homogeneity assumption showed that it could not be rejected, and thus none of the proposed moderating variables altered the aerobic fitness-psychosocial reactivity relationship. Various underlying mechanisms which may contribute to this response are discussed, and future research directions are presented.
本文综述了有氧适能对心理社会应激源抵抗力的影响。为了梳理在研究有氧适能与心理社会应激反应之间关系时出现的不一致结果，我们进行了一项荟萃分析。对34项研究的结果进行了统计合并，这些研究来自1449名受试者，有92个效应量估计值，用于比较心理社会应激源任务和唤醒指标。平均效应量估计值为0.48，与零有显著差异（P小于0.01），这表明有氧适能良好的受试者与对照组或基线值相比，心理社会应激反应有所降低。齐性假设检验表明该假设不能被拒绝，因此，所提出的任何调节变量都没有改变有氧适能与心理社会反应性之间的关系。文中讨论了可能导致这种反应的各种潜在机制，并提出了未来的研究方向。
