The purpose of this study was to examine African American toddlers' cortisol response to acute physical play activity within a full-time subsidized day care environment. Saliva samples were taken from participants (N = 22, ages 26-45.5 months) before and after physical play and control play conditions at the same time of day. Actiheart monitors were used to estimate the intensity of the play conditions. Although heart rate and other indicators were significantly higher during physical play, no change in cortisol levels was seen pre- to postphysical play. Further research is needed to better understand the cortisol response observed.
本研究旨在考察在全日制补贴日托环境中，非洲裔美国学步儿童对急性体力活动的皮质醇反应。在同一天的体力活动和对照活动条件下，在活动前和活动后从参与者（N=22，年龄 26-45.5 个月）中采集唾液样本。使用 Actiheart 监测器来估计活动条件的强度。尽管在体力活动期间心率和其他指标显著升高，但在体力活动前后皮质醇水平没有变化。需要进一步的研究来更好地理解所观察到的皮质醇反应。
