背景和目的。尽管人们对有氧运动对心血管健康的益处了解很多，但关于有氧运动对运动表现的影响的研究却很少。本研究旨在探讨有氧运动对老年人手指运动追踪过程中视觉空间信息加工的影响。科目15名老年受试者（平均年龄=83.2岁，SD = 5.7，范围= 72-91）从高级住宅区被随机分配到对照组或实验（运动）组。12名受试者完成了研究，从10名受试者获得的数据用于数据分析（排除2名对照受试者，以允许实验组和对照组之间的配对分析）。对照组（n=5）的平均年龄为80.2岁（SD=7.8）。实验组受试者（n=5）的平均年龄为84.8岁（SD=2.5）。方法.干预包括每周3次连续8周的团体运动，包括健美操（如原地踏步、侧步、模拟拳击）、固定、骑自行车和步行。在训练前后进行手指运动跟踪测试和次极量分级运动耐力台阶测试，以确定手指运动跟踪和任何有氧训练效果的变化。结果配对t检验显示，实验组与控制组在前测到后测的追踪能力上存在差异。两组之间的台阶测试性能没有差异。讨论和结论。这项小规模研究的结果表明，对于老年人来说，手指运动跟踪性能可以通过有氧运动来改善，尽管没有有氧训练效果。对信息加工的处理效果的可能机制进行了讨论。
Background and Purpose. Although much is known about the benefits of aerobic exercise on cardiovascular health, little research has been done on the effect of aerobic exercise on motor performance. This study examined whether aerobic exercise has an effect on visuospatial information processing during finger-movement tracking in elderly subjects. Subjects. Fifteen elderly subjects (mean age=83.2 years, SD = 5.7, range = 72-91) from a senior housing complex were randomly assigned to a control group or an experimental (exercise) group. Twelve subjects completed the study, and data obtained for 10 subjects were used for data analysis (2 control subjects were eliminated to allow for matched-pairs analysis between the experimental and control groups). The control group (n=5) had a mean age of 80.2 years (SD=7.8). Subjects in the experimental group (n=5) had a mean age of 84.8 years (SD=2.5). Methods. The intervention consisted of group exercise 3 times a week for 8 consecutive weeks, and included calisthenics (eg, marching in place, side stepping, mock boxing), stationary, bicycling, and walking. A finger-movement tracking test and submaximal graded exercise tolerance step tests were performed before and after training to determine changes in finger-movement tracking and any aerobic training effects. Results. Matched-pairs t tests showed a difference in tracking from pretest to posttest in the experimental group compared with the control group. Step test performance did not differ between the 2 groups. Discussion and Conclusion. The results of this small-scale study with a limited number of subjects indicate that, for elderly people, finger-movement tracking performance can improve with aerobic exercise, despite the absence of an aerobic training effect. Possible mechanisms for the treatment effect on information processing are discussed.
