The aim of this study was to examine the effects of a 24-week aerobic exercise training program on daily psychological processes and occurrence of stressors in a group of previously physically underactive family caregivers of patients with dementia. As part of the Fitness, Aging, and STress (FAST) randomized controlled trial, 68 participants (F = 55; M = 13) were randomized to either a staff-supported, 24-week aerobic training ( = 34) program or waitlist control ( = 34) group. Approximately 2 weeks prior to randomization, ecological momentary assessments were completed 6 times per day for 7 days and again in the 24th week of the trial to assess exposure to levels of momentary positive affect, negative affect, rumination, control, and the occurrence of stressors throughout the day. These secondary analyses with data from 56 of the participants revealed that the intervention group showed a significantly larger increase in daily positive affect and perceptions of control compared to control participants over the course of the intervention. A treatment effect was also found for negative affect and rumination, whereby both decreased to a greater extent in the intervention group when compared with participants in the control condition. The 24-week aerobic training program had significant impacts on daily psychological processes in family caregivers, deepening our understanding of the robust effects of exercise on mental health.
本研究的目的是检验一项为期24周的有氧运动训练计划，对一组此前身体活动不足的痴呆症患者家庭照料者的日常心理过程和应激源发生情况的影响。作为“健身、衰老与压力”（FAST）随机对照试验的一部分，68名参与者（女性=55名；男性=13名）被随机分为两组，一组是由工作人员支持的为期24周的有氧训练（n=34）计划，另一组是候补对照组（n=34）。在随机分组前约2周，每天进行6次生态瞬时评估，持续7天，并在试验的第24周再次进行，以评估全天瞬时积极情绪、消极情绪、沉思、掌控感水平的暴露情况以及应激源的发生情况。对56名参与者的数据进行的这些二次分析显示，与对照组参与者相比，干预组在干预过程中每日积极情绪和掌控感的提升显著更大。在消极情绪和沉思方面也发现了治疗效果，与对照组参与者相比，干预组的消极情绪和沉思程度下降得更多。这项为期24周的有氧运动训练计划对家庭照料者的日常心理过程产生了显著影响，加深了我们对运动对心理健康的强大作用的理解。
