To study the physical condition of adolescents with mild to moderate mental retardation (MR), twenty-eight MR students from Rajanukul school were evaluated for their fitness components compared to 14 normal students.
Per cent body fat (%BF) was calculated from three sites of skinfold thickness. The cardiorespiratory endurance was assessed using graded exercise testing and Quinton gas analyzer. Isometric leg strength was measured with dynamometer, and flexibility was measured by sit and reach test.
Compared between MR and normal subjects, %BF was higher in the MR group without statistic significance. Five MR females had %BF > 30. The mean VO2peak was about 70 per cent of normal. The leg strength and flexibility were very poor.
The MR adolescents had a significantly lower level of physical fitness and more prevalence of obesity than normal students. Appropriate physical activities should be emphasized for health promotion and disease prevention.
为研究轻度至中度智力发育迟缓（MR）青少年的身体状况，对拉贾努库尔学校的28名患有MR的学生进行了体能成分评估，并与14名正常学生进行比较。
通过三个部位的皮褶厚度计算体脂百分比（%BF）。使用分级运动测试和昆顿气体分析仪评估心肺耐力。用测力计测量等长腿部力量，通过坐位体前屈测试测量柔韧性。
与正常受试者相比，MR组的%BF较高，但无统计学意义。五名患有MR的女性%BF>30。平均最大摄氧量（VO2peak）约为正常水平的70%。腿部力量和柔韧性非常差。
与正常学生相比，患有MR的青少年体能水平明显较低，肥胖患病率更高。应强调进行适当的体育活动以促进健康和预防疾病。
