Emerging evidence suggests that outdoor group exercise may reduce stress more than indoor group exercise because the outdoor environment provides unique mental health benefits. Stress leads to illnesses and diseases, but exercise mitigates harmful impacts. This study explored differences in perceived stress and outdoor physical activity participation among college students in an indoor or outdoor group exercise class. Data were collected pre-, mid- (after four sessions), and post-intervention (after eight sessions). Seventeen participants indicated an interest in the study, but 13 signed up. Participants completed a four-week group exercise intervention that met twice weekly in outdoor and indoor conditions. Mixed ANOVAs with Tukey post hoc tests determined between-group differences in perceived stress and outdoor physical activity levels. Partial eta-squared () estimated effect sizes. Significant differences in perceived stress scores existed across time for the whole sample [(2, 12) = 48.359, < 0.001, = 0.890] and for the interaction between time and condition [(2, 12) = 10.051, = 0.003, = 0.626]. Post hoc analysis revealed that the outdoor group's perceived stress ( < 0.001) was reduced more than the indoor group post-intervention ( = 0.028).
新出现的证据表明，户外团体运动可能比室内团体运动更能减轻压力，因为户外环境对心理健康有独特的益处。压力会导致疾病，但运动可以减轻有害影响。本研究探讨了参加室内或户外团体运动课程的大学生在感知压力和户外体育活动参与方面的差异。在干预前、中期（四节课后）和后期（八节课后）收集数据。17名参与者表示对该研究感兴趣，但13人报名参加。参与者完成了一项为期四周的团体运动干预，该干预在户外和室内条件下每周进行两次。采用混合方差分析和Tukey事后检验来确定感知压力和户外体育活动水平的组间差异。偏 eta 平方（）估计效应大小。整个样本在不同时间的感知压力得分存在显著差异[（2, 12） = 48.359， < 0.001， = 0.890]，时间和条件之间的交互作用也存在显著差异[（2, 12） = 10.051， = 0.003， = 0.626]。事后分析显示，干预后户外组的感知压力（ < 0.001）比室内组降低得更多（ = 0.028）。
