对27名患有不同程度失明但没有其他已知障碍的儿童(年龄7-17岁)进行了身体健康评估。随机选择的27名视力正常的儿童也进行了评估。在跑步机上进行递增运动试验时，直接测量最大摄氧量(.ovrhdot.VO2max)。在完全失明的儿童中，.ovrhdot.VO2max有显著和实质性的减少(平均值为+-。标准差35.0.+-7.5毫升.cntdot。Min-1.cntdo.Kg-1，与正常儿童(45.9±-)比较。6.6毫升.cntdot。Min-1.cntdo.Kg-1)。部分视力儿童的.ovrhdot.VO2max下降明显，但幅度较小。在视力受损的儿童中，通过阶梯测试评估的健康状况显著降低，在完全失明的儿童中，皮肤褶皱厚度也明显增加。通过问卷调查评估，每个儿童的习惯性体力活动水平与最大摄氧量相关(r=0.53p<；0.0001)。盲童的活动量明显低于正常儿童，考虑到他们不同的活动水平，盲童和正常儿童的平均.ovrhdo.VO2max之间的差异变得不显著。结论是，完全失明的儿童比其他儿童更不健康，至少部分原因是他们的习惯性活动水平较低。
Twenty-seven children (age 7-17 years) with varying degrees of blindness but with no other known disorder were assessed for physical fitness. Twenty-seven randomly selected children with normal eyesight were also assessed. Maximum oxygen uptake (.ovrhdot.VO2max) was measured directly during a progressive exercise test on a treadmill. There was a significant and substantial reduction in .ovrhdot.VO2max in totally blind children (mean .+-. standard deviation 35.0 .+-. 7.5 ml .cntdot. min-1 .cntdot. kg-1) compared with normal children (45.9 .+-. 6.6 ml .cntdot. min-1 .cntdot. kg-1). Partially sighted children had a significant but smaller reduction in .ovrhdot.VO2max. Fitness assessed by a step-test was significantly reduced in the visually impaired children and skin-fold thickness was also significantly greater in totally blind children. The level of habitual physical activity for each child, as assessed by a questionnaire, correlated with .ovrhdot.VO2max (r = 0.53, p < 0.0001). Blind children were significantly less active than normal children, and the difference between mean .ovrhdot.VO2max for blind and normal children became non-significant when their different activity levels were taken into account. It is concluded that totally blind children are less fit than other children at least partly because of their lower level of habitual activity.
