This study aimed to examine in healthy older adults the effects of dance/movement training (DMT) on the cortisol awakening response (CAR), a marker of chronic stress. Forty participants (mean age = 67.45, 75% women) were randomized into three groups: DMT ( = 12) - a set of exercises to promote gross motor skills, body awareness, and socialization; aerobic exercise training (AT; = 14) - high intensity activity on a recumbent bicycle, and wait list (WL; = 14). Both DMT and AT groups were supervised by licensed instructors and met three times a week for three months. Before and after their respective program, participants of all groups provided saliva samples on 3 d at 0-, 30- and 60-min after awakening, and had their fitness level evaluated. A significant group × time interaction ( = 5.79, = .01, = 0.25) was found, with the DMT group showing lower salivary cortisol values post-training, while the other two groups showed no change from baseline in their CAR. Cardiorespiratory fitness improved only in the AT group, while DMT showed no group-specific physical functioning improvements. The results are discussed in terms of the importance of physical and psychological effects of training on change in cortisol levels.
本研究旨在探讨舞蹈/运动训练(DMT)对健康老年人皮质醇觉醒反应(CAR)的影响,CAR 是慢性应激的标志物。40 名参与者(平均年龄 67.45 岁,75%为女性)被随机分为三组:舞蹈/运动训练(DMT; = 12)——一组促进大运动技能、身体意识和社交能力的练习;有氧运动训练(AT; = 14)——在卧式自行车上进行高强度活动,以及候补名单(WL; = 14)。DMT 和 AT 两组均由持照教练监督,每周三次,为期三个月。在各自的项目之前和之后,所有组别的参与者在 3 天内分别在 0、30 和 60 分钟后提供唾液样本,并评估他们的健康水平。发现组间时间交互作用显著( = 5.79, = .01, = 0.25),DMT 组在训练后唾液皮质醇值较低,而其他两组的 CAR 与基线相比没有变化。只有 AT 组的心肺功能得到改善,而 DMT 组在特定于组的身体功能方面没有改善。结果从训练对皮质醇水平变化的身心影响的重要性方面进行了讨论。
