Few data are available regarding maximal exercise testing of mentally retarded individuals. No data are available on the reliability of maximal exercise testing of mentally retarded individuals. The purpose of this study was to determine the reliability of graded exercise testing of mentally retarded adolescents and adults. The testing was conducted at two geographically different centers. At Center A, 14 mentally retarded adolescents (11 boys, three girls) with Down syndrome, who were educable or trainable, were recruited from a nonresidential school. The subjects completed two Balke-Ware treadmill protocols until exhaustion. The treadmill time and heart rate (HR) were recorded. The time between tests was approximately one week. At Center B, 21 mentally retarded adults (14 women, seven men means IQ = 56) were recruited from local workshops and group homes. These subjects completed a treadmill walking protocol, with metabolic measurements, until exhaustion. The time between tests varied from one to four months. At Center A, the subjects achieved a mean treadmill time of 8.72min on test one and 8.84min on test two (means HR = 174 and 175bpm, respectively). The reliability coefficient between the two tests was .94. At Center B, the subjects achieved a mean V0(2)max of 27.2mL.kg-1.min-1 on test one and 26.9mL.kg-1.min-1 on test two. The reliability coefficient was .93. These data show that maximal exercise testing is reliable for these populations of mentally retarded individuals, exhibiting similar values to their nonretarded peers.
关于智障人士的最大运动测试，可用数据很少。目前尚无关于智障人士最大运动测试可靠性的数据。本研究的目的是确定智障青少年和成年人分级运动测试的可靠性。测试在两个地理位置不同的中心进行。在中心A，从一所走读学校招募了14名患有唐氏综合征、可教育或可训练的智障青少年（11名男孩，3名女孩）。受试者完成了两个Balke-Ware跑步机测试方案，直至力竭。记录跑步机运动时间和心率（HR）。两次测试之间的时间间隔约为一周。在中心B，从当地工厂和集体之家招募了21名智障成年人（14名女性，7名男性，平均智商=56）。这些受试者完成了一项跑步机步行测试方案，并进行了代谢测量，直至力竭。两次测试之间的时间间隔从1个月到4个月不等。在中心A，受试者在第一次测试中的平均跑步机运动时间为8.72分钟，在第二次测试中为8.84分钟（平均心率分别为174次/分钟和175次/分钟）。两次测试之间的可靠性系数为0.94。在中心B，受试者在第一次测试中的平均最大摄氧量（V0(2)max）为27.2mL.kg-1.min-1，在第二次测试中为26.9mL.kg-1.min-1。可靠性系数为0.93。这些数据表明，最大运动测试对这些智障人群是可靠的，其结果与非智障同龄人相似。
