After a randomized controlled trial showing that improvement on some aspects of cognitive function was related to adherence to an exercise program, determinants of adherence and maintenance were further studied. Older adults with mild cognitive impairment were contacted 6 mo after the end of exercise programs for a telephone interview addressing patterns of adherence and determinants of maintenance. Mean adherence during the trial was 53%. About one third of participants had lapses during the trial but completed, one third had no lapses, and one third dropped out or never started. Practical barriers (time, location) were related to not starting and functional limitations to dropout. After the trial 25% of participants continued the programs, 14% reported intention to continue, and 61% quit. Maintenance was determined by fewer health complaints, higher satisfaction with the programs, and better adherence during the programs. Although maintenance was low, this study identified several reasons and barriers to adherence and maintenance that could be addressed.
一项随机对照试验表明，认知功能某些方面的改善与坚持锻炼计划有关，之后对坚持和维持锻炼计划的决定因素进行了进一步研究。在锻炼计划结束6个月后，联系了患有轻度认知障碍的老年人进行电话访谈，询问他们的坚持模式和维持锻炼计划的决定因素。试验期间的平均坚持率为53%。约三分之一的参与者在试验期间有中断但完成了锻炼计划，三分之一没有中断，三分之一退出或从未开始锻炼。实际障碍（时间、地点）与未开始锻炼有关，功能受限与退出有关。试验结束后，25%的参与者继续参加锻炼计划，14%表示有继续参加的意愿，61%退出。维持锻炼计划的决定因素包括较少的健康问题投诉、对锻炼计划较高的满意度以及在锻炼计划期间更好的坚持情况。尽管维持锻炼计划的比例较低，但这项研究确定了几个可以解决的坚持和维持锻炼计划的原因及障碍。
