Using bicycle ergometers, physical working capacity was determined in 61 deaf, 22 visually handicapped, and 67 mentally retarded children 8 to 17 years of age. Compared to the normal population, the working capacities per kilogram body weight of the deaf children, particularly the girls, were superior to the other groups and to the normal population. The visually handicapped had lower working capacities, while those of the retarded children were similar to the normals. The work efficiency was similar in both groups. For the boys and younger girls, the maximum oxygen uptakes per kilogram body weight were similar in the deaf and visually handicapped, results that were contrary to the working capacity studies. The difference could be explained by postulating that the deaf children did not work to maximal values though lactic acid and respiratory quotient data suggested that they did. The maximum heart rates of the deaf children were lower than the visually handicapped.
使用自行车测力计，对61名8至17岁的聋哑儿童、22名视力障碍儿童和67名智力发育迟缓儿童进行了身体工作能力测定。与正常人群相比，聋哑儿童每千克体重的工作能力，尤其是女孩，优于其他组和正常人群。视力障碍儿童的工作能力较低，而智力发育迟缓儿童的工作能力与正常人相似。两组的工作效率相似。对于男孩和年龄较小的女孩，聋哑儿童和视力障碍儿童每千克体重的最大摄氧量相似，这一结果与身体工作能力研究相反。这种差异可以通过假设聋哑儿童没有达到最大值来解释，尽管乳酸和呼吸商数据表明他们达到了。聋哑儿童的最大心率低于视力障碍儿童。
