This study investigated the effect of combined exercise training on indices of body composition, physical fitness and lipid profile in adolescents with mental retardation.
Thirty adolescents with mental retardation (total IQ, 45-70) received exercise training (n = 15) or no training (n = 15). Groups were matched for age, sex and mental retardation. Before and after the intervention period, indices of body composition, physical fitness and lipid profile were measured.
In comparison with the control group, weight, body mass index, waist and fat mass decreased significantly, while relative fat-free mass increased. The level of triglycerides, total cholesterol and low-density lipoprotein decreased significantly, while high-density lipoprotein increased. Muscle strength, muscle fatigue resistance and sit-to-stand were ameliorated. PeakVO2/peak power decreased significantly. The distance covered in the 6-min walk test (6MWT) increased with 50 m.
In conclusion, combined exercise training has a positive effect on indices of obesity, physical fitness and lipid profile in adolescents with mental retardation.
本研究调查了联合运动训练对智力发育迟缓青少年身体成分、体能和血脂指标的影响。
30名智力发育迟缓青少年（总智商45 - 70）接受运动训练（n = 15）或不接受训练（n = 15）。两组在年龄、性别和智力发育迟缓程度上相匹配。在干预期前后，测量身体成分、体能和血脂指标。
与对照组相比，体重、体重指数、腰围和脂肪量显著降低，而相对去脂体重增加。甘油三酯、总胆固醇和低密度脂蛋白水平显著降低，而高密度脂蛋白增加。肌肉力量、抗肌肉疲劳能力和从坐到站的能力得到改善。峰值摄氧量/峰值功率显著降低。6分钟步行试验（6MWT）所走距离增加了50米。
总之，联合运动训练对智力发育迟缓青少年的肥胖指标、体能和血脂状况有积极影响。
