Abstract：
This study explored the acute effects of different running intensities on cognitive and motor performances in individuals with intellectual disability (ID). An ID group (age, M = 15.25 years, SD = 2.76) and a control group without ID (age, M = 15.11 years, SD = 1.54) performed visual simple and choice reaction times, auditory simple reaction time, and finger tapping tests before and after running at low or moderate intensity (30% and 60% of heart rate reserve [HRR], respectively). Visual simple reaction time values decreased (p < .001) after both intensities at all time points with higher (p = .007) extend after the 60% HRR intensity for both groups. After both intensities, the VCRT decreased (p < .001) in the ID group at all time points compared with preexercise (Pre-EX) while, in the control group, these values decreased (p < .001) only immediately (IM-EX) and after 10 min (Post-10) of exercise cessation. Compared withs Pre-EX, in the ID group, the auditory simple reaction time values decreased (p < .001) at all time points after the 30% HHR intensity whereas, after the 60% HRR, these values decreased only at IM-EX (p < .001), Post-10 (p = .001) and Post-20 (p < .001). In the control group, auditory simple reaction time values decreased (p = .002) only after the 30% HRR intensity at IM-EX. The finger tapping test increased at IM-EX (p < .001) and at Post-20 (p = .001) compared to Pre-EX in both groups only after the 30% HHR intensity and for the dominant hand. The effect of physical exercise on cognitive performances in individuals with ID seems to depend on the cognitive test type as well as the exercise intensity.
摘要：
这项研究探讨了不同跑步强度对智力障碍（ID）个体认知和运动表现的急性影响。ID组(年龄，M=15.25年，SD=2.76)和无ID的对照组(年龄，M=15.11年，SD=1.54)执行视觉简单和选择反应时间，听觉简单反应时间，低强度或中等强度跑步前后的手指敲击测试（心率储备[HRR]的30％和60％，分别)。在所有时间点的两种强度之后,视觉简单反应时间值降低(p<.001),在两组的60%HRR强度之后,更高的(p=.007)延长。在两种强度之后，与运动前(Pre-EX)相比，ID组的VCRT在所有时间点都降低(p<.001)，在对照组中，这些值仅在运动停止后10分钟（IM-EX）和10分钟后（10后）才降低（p<.001）。与Pre-EX相比，在ID组中，在30％HHR强度后的所有时间点，听觉简单反应时间值降低（p<.001），在60%的HRR之后，这些值仅在IM-EX（p<.001）时降低，后10（p=.001）和后20（p<.001）。在对照组中，仅在IM-EX的30％HRR强度之后，听觉简单反应时间值降低（p=.002）。仅在30%HHR强度之后和对于优势手,在两组中,与Pre-EX相比,手指敲击测试在IM-EX(p<.001)和在20后(p=.001)增加。体育锻炼对ID患者认知表现的影响似乎取决于认知测试类型和运动强度。
