| 目的：观察肥胖青少年在4周有氧运动减肥前后其身体形态、血脂和脂蛋白酯酶（lipoprotein lipase，LPL）的变化。方法：以15~17岁肥胖青少年32人（男女各16名）为研究对象，根据心率控制运动强度，进行4周中低强度有氧运动为主，结合适当饮食控制的运动减肥训练，并分别于入营第一天和出营前一天测定受试者身体形态、血脂和LPL等指标。结果：4周有氧运动后，肥胖青少年体重、BMI和体脂率显著下降；血清甘油三酯、总胆固醇和低密度脂蛋白含量显著降低，高密度脂蛋白水平无明显变化；空腹血清LPL的活性明显提高。结论：4周中低强度有氧运动结合适当饮食控制能够明显改善肥胖青少年身体形态、血脂代谢水平，显著提高LPL酶活性，一定程度上改善了肥胖患者的脂代谢状态，对中小强度有氧运动有效促进脂肪分解具有重要作用。 |
| 英文摘要: |
| Purpose: To observe the body shape, blood lipid and LPL changes of obese teenagers before and after 4-week aerobic exercise for losing weight. Method: 32 obese teenagers (16 males and 16 females at the age of 15-17) were selected as the subjects. The exercise intensity was controlled according to heart rate. 4-week low intensity aerobic exercise with controlled diet was arranged. The indexes of body shape, blood lipid and LPL were measured on the first day and last day of the training camp. Result: After the 4-week aerobic exercise, the body weight, BMI and body fat rate of the subjects dropped significantly. The serum triglyceride, total cholesterol and low density lipoprotein content decreased obviously. The high density lipoprotein level had no significant change. Fasting serum lipoprotein lipase activity improved significantly. Conclusion: 4-week low intensity aerobic exercise with controlled diet can obviously change the body shape, blood lipid metabolism, significantly accelerate the activity of LPL and improve the lipid metabolic state to some extent. So low intensity aerobic exercise plays an important role in promoting adipose decomposition. |
