Physical activity is the basic factor to the human being in order to assume his place in society. Blind persons are often sedentary, which compromises its physical capacity. The present work evaluates the blind person's physical capacity, analysing possible differences related to sex, age and life time blindness. The sample was constituted by 27 blind (congenital and noncongenital), 18 male and 9 female, aged between 17 and 37 years old. To evaluate previous physical activity, a questionnaire, was answered which showed a dominant sedentary population. The maximum oxygen uptake was determined in a treadmill test using standard procedures (Bruce protocol). Medium results for boys were 45.85 +/- 8 ml/kg/min and for girls were 34.46 +/- 3.8 ml/kg/min. The difference between congenital and acquired blindness on the VO2max values was 2.9 ml/kg/min, not statistically significant (p = 0.468). Those findings lead us to consider that aerobic capacity mostly depends on type and intensity of physical exercise which may be temporary related to the onset of blindness and visual impairment degree.
身体活动是人类在社会中立足的基本要素。盲人往往久坐不动，这损害了他们的身体能力。本研究评估了盲人的身体能力，分析了与性别、年龄和失明时长相关的可能差异。样本由27名盲人（先天性和非先天性）组成，其中18名男性和9名女性，年龄在17至37岁之间。为了评估以往的身体活动情况，他们回答了一份问卷，结果显示大部分人久坐不动。使用标准程序（布鲁斯方案）在跑步机测试中测定最大摄氧量。男孩的平均结果为45.85±8毫升/千克/分钟，女孩为34.46±3.8毫升/千克/分钟。先天性失明和后天性失明在最大摄氧量值上的差异为2.9毫升/千克/分钟，无统计学意义（p = 0.468）。这些发现使我们认为有氧能力主要取决于体育锻炼的类型和强度，这可能与失明的发生和视力损害程度暂时相关。
