The influence of baseline sleep on exercise‐induced cognitive change in cognitively unimpaired older adults: A randomised clinical trial

Observational studies consistently demonstrate that physical activity is associated with elevated cognitive function, however, there remains significant heterogeneity in cognitive outcomes from randomized exercise interventions. Individual variation in sleep behaviours may be a source of variability in the effectiveness of exercise‐induced cognitive change, however this has not yet been investigated. The current study aimed to (1) investigate the influence of a 6‐month exercise intervention on sleep, assessed pre‐ and post‐intervention and, (2) investigate whether baseline sleep measures moderate exercise‐induced cognitive changes.

观察性研究一直表明，身体活动与认知功能的提升有关，然而，随机运动干预在认知结果方面仍存在显著的异质性。睡眠行为的个体差异可能是运动诱导的认知变化有效性存在差异的一个原因，但这尚未得到研究。当前的研究旨在（1）研究为期6个月的运动干预对睡眠的影响，在干预前后进行评估；（2）研究基线睡眠指标是否会调节运动诱导的认知变化。
