目的：一个目的是验证运动后焦虑减少是由日常关心和担忧的“暂停”引起的假设，第二个目的是记录运动后高特质焦虑女性状态焦虑的变化幅度。方法：焦虑的女性(N=14)完成4个随机排序的条件：仅运动，骑自行车20min(40%的(V)超过点O-2峰值)，然后恢复20min；仅研究，坐在自行车功率计上学习40min，运动/学习，学习时骑车20min(40%的(V)超过点O-2峰值)，然后坐在自行车上学习20min；对照组，安静地坐在功率计上40min。结果：在每种状态前后都进行了状态焦虑评定。状态焦虑在仅运动状态下降低(平均原始变化分数+/-95%可信区间为4.3+/-3.5；t=2.3，P=0.04，d=0.52)。调整条件焦虑评分后，95%可信区间不包括零(调整后的变化得分+/-95%可信区间为3.3+/-3.2)。结论：由于运动/学习状态焦虑的降低在运动/学习条件下受阻(t=-0.05，P=0.97，d=0.01)，且相关的Cis为零(未调整的0.1+/-3.4，调整后的0.8+/-3.2)，这一结果支持运动后焦虑的减少是因为运动为个人提供了一段摆脱日常担忧的时间。
Purpose: One purpose was to test the hypothesis that anxiety reductions following exercise are caused by a "time out" from daily cares and worries, and the second purpose was to document the magnitude of the change in state anxiety after exercise in high trait anxious females. Methods: Anxious women (N = 14) completed four randomly ordered conditions: Exercise Only, 20 min of cycling (40% of (V) over dot O-2peak) followed by 20 min of recovery; Study Only, 40 min of studying while sitting on a cycle ergometer, Exercise/Study, 20 min of cycling (40% of (V) over dot O-2peak) while studying followed by 20 min of studying while sitting on the cycle egometer; and Control, sitting quietly on an ergometer for 40 min. Results: State anxiety was assessed before and after each condition. State anxiety was reduced following the Exercise Only condition (mean raw change score +/- 95% confidence interval (CI) of 4.3 +/- 3.5; t = 2.3, P = 0.04, d = 0.52). The 95% CI did not include zero after adjusting for precondition anxiety scores (adjusted change score +/- 95% CI of 3.3 +/- 3.2). Conclusions: Because the reduction in state anxiety following exercise was blocked in the Exercise/Study condition (t = -0.05, P = 0.97, d = 0.01) and the associated CIs included zero (unadjusted 0.1 +/- 3.4, adjusted 0.8 +/- 3.2), the findings support the hypothesis that anxiety reductions following exercise occur because exercise affords individuals a time out from daily worries.
