Leisure activities are believed to contribute to healthy ageing. We compared the effects of choir singing and playing on cortisol levels in Japanese older adults. We also examined its relevance to the older adults' emotional affect and cognitive performance.
Thirty-six older adults participated either in choir or playing, within a 2 (groups)×2 (time points) design. Dependent measures included levels of salivary cortisol, as well as key psychological, cognitive, and neuropsychological measures.
A significant two-way interaction was observed, showing that levels of salivary cortisol decreased for the choir but increased for the groups. The decrease in salivary cortisol for the choir group correlated with the participant's negative affect and their degree of cognitive impairment.
Choir singing has the potential to reduce Japanese older adults' physiological stress. The decreases can be seen more prominently for people with stronger negative affect and cognitive impairment. Further research is required to replicate these effects.
休闲活动被认为有助于健康老龄化。我们比较了唱诗班演唱和演奏对日本老年人皮质醇水平的影响。我们还研究了其与老年人情绪影响和认知表现的相关性。
36名老年人参与了唱诗班或演奏活动，采用2（组）×2（时间点）设计。相关测量指标包括唾液皮质醇水平，以及关键的心理、认知和神经心理学测量指标。
观察到显著的双向交互作用，表明唱诗班组唾液皮质醇水平下降，而演奏组上升。唱诗班组唾液皮质醇的下降与参与者的负面影响及其认知障碍程度相关。
唱诗班演唱有可能减轻日本老年人的生理压力。对于负面影响较强和认知障碍较严重的人，这种下降更为明显。需要进一步研究来重复这些效果。
